HVAC Questions, Answered

Most gas furnaces last 15 to 20 years. Annual maintenance, regular filter changes and proper sizing all help a furnace reach the upper end of that range.

In the GTA, furnaces work hard from October to April, so a furnace in a Toronto home racks up a lot of run time each year. Regular maintenance, regular filter changes and a properly sized system help it reach the upper end of that range. If yours is getting close to 15 years, start planning before it fails in a January cold snap.

Common signs are an age of 15 years or more, frequent repairs, rising gas bills, uneven heating, a yellow or flickering burner flame, and new rattling or banging noises. If you’re seeing several of these, it’s worth getting a replacement quote.

An older furnace can also become a safety concern, especially if the heat exchanger is cracked. During a visit, our technicians can tell you whether a repair still makes sense or whether you’d be better off putting that money toward a new, more efficient system.

The right size depends on a heat-loss calculation, not just square footage. Insulation, windows, air leakage and the number of storeys all matter. An oversized furnace short-cycles and an undersized one struggles on cold days.

Toronto’s winter design temperature is around -20°C, and that’s the cold day a furnace in the GTA needs to be sized for. We do a room-by-room heat-loss calculation during a free in-home consultation, so your furnace heats evenly, runs quietly and doesn’t waste gas.

AFUE stands for Annual Fuel Utilization Efficiency. It’s the percentage of fuel a furnace turns into heat for your home. A 96% AFUE furnace turns 96 cents of every gas dollar into heat.

Older furnaces were often 60% to 80% efficient, which means up to 40 cents of every dollar spent on gas went up the chimney. Today, high-efficiency condensing furnaces in Ontario are typically rated 95% AFUE or higher.

A single-stage furnace runs at full output every time. A two-stage furnace has a low and high setting, and a modulating furnace adjusts in small steps. More stages mean steadier temperatures, quieter operation and better efficiency.

Single-stage furnaces cost less upfront but can create hot and cold swings. Two-stage and modulating furnaces run longer at lower output, which keeps temperatures more even, reduces noise and improves comfort, especially in two-storey homes.

For most GTA homes, yes. Older furnaces often run at 60% to 80% efficiency, while new high-efficiency models reach 95% or more, so less gas is wasted every winter.

Most GTA homes heat with natural gas from Enbridge Gas, so every percentage point of efficiency shows up on your gas bill over a long Ontario winter. A high-efficiency furnace also vents safely through the side of your home with PVC piping, which frees up your old chimney.

Most furnace replacements are completed in a single day. Jobs that need new venting, ductwork changes or a combined furnace and air conditioner installation can take longer.

Our installers remove your old furnace, set and connect the new one, test the venting, gas pressure and safety controls, and walk you through how to use it. We’ll let you know in advance if your installation needs any extra time.

Check that the thermostat is set to heat and the fan is on Auto, not On. A clogged filter, a dirty flame sensor, an ignition problem or an overheating safety switch can also cause cold air. If it continues, call for service.

If the furnace just finished a heating cycle, the air may also feel cooler as the blower clears remaining heat from the system. If you hear repeated clicking or see a flashing error light on the furnace, note the code and give us a call.

Short cycling is often caused by a dirty filter, a dirty flame sensor, a poorly placed thermostat or a furnace that’s too large for the home. It wastes energy and wears out parts, so it’s worth having checked.

A thermostat placed near a heat source or in direct sun can also trigger short cycles. Our technicians can track down the cause and fix it, whether it’s a simple cleaning, a control problem or a sizing issue.

Standard 1-inch filters should be checked monthly and replaced every 1 to 3 months. Thicker 4- to 5-inch media filters usually last 6 to 12 months. Change them more often if you have pets or renovation dust.

A clogged filter restricts airflow, makes your furnace work harder and can even cause it to overheat and shut off. Write the date on each new filter so you always know when it’s due, and keep a spare on hand.

A tune-up typically includes inspecting and cleaning the burners and flame sensor, checking the ignition, heat exchanger, venting and safety controls, testing gas pressure and airflow, and checking the filter and blower.

We also check the thermostat, look for signs of wear or corrosion, and test carbon monoxide levels where appropriate. If we find anything that needs attention, we’ll explain it clearly and give you options before doing any work.

Once a year, ideally in the fall before the heating season. Regular service helps catch small problems early and keeps your furnace running safely and efficiently.

In the GTA, book your furnace tune-up in September or October, before the first cold nights and before the busiest repair season. A yearly service also helps keep your manufacturer warranty valid, since many warranties require proof of regular maintenance.

A bang at start-up can mean delayed ignition, squealing often points to the blower motor or belt, rattling can be loose panels or ductwork, and constant humming can be an electrical issue. Unusual new noises should be checked.

Some sounds are normal, like a soft whoosh as the burners light or a click from the controls. Loud, new or worsening noises usually mean a part is wearing out, and fixing it early often prevents a bigger repair later.

Leave your home right away without using light switches, phones or appliances inside. From outside, call your gas utility’s emergency line or 911. Don’t go back in until it’s declared safe.

In the GTA, call the Enbridge Gas emergency line at 1-866-763-5427 or 911 from outside your home. Don’t try to find the leak yourself. Once Enbridge has made the area safe, our licensed gas technicians can inspect and repair your appliances.

Yes. In Ontario, homes with a fuel-burning appliance, a fireplace or an attached garage must have working CO alarms outside all sleeping areas. Test them monthly and replace them as the manufacturer recommends.

This is required under the Ontario Fire Code. CO is colourless and odourless, so an alarm is the only way to know it’s there. If your CO alarm sounds, get everyone outside, call 911, and don’t go back in until emergency services say it’s safe.

High-efficiency furnaces produce condensation that drains away through a line and sometimes a pump. A clogged drain line, a failed condensate pump or a leaking humidifier are the usual causes. Turn the furnace off and call if water is pooling.

A small amount of water near a high-efficiency furnace isn’t always serious, but it shouldn’t be ignored. Water can damage the furnace’s electronics and your floors, so it’s best to have a technician find the source.

A flame sensor confirms the burner is lit. If it gets dirty, the furnace may light and then shut off within seconds. Cleaning it is a routine part of a furnace tune-up.

Over time, the flame sensor collects a thin layer of buildup that makes it hard to detect the flame. If your furnace keeps lighting and shutting off, a dirty flame sensor is one of the most common causes.

No. In Ontario, gas appliances must be installed by a licensed gas technician, and installations often need a permit and inspection. A professional install also protects your manufacturer warranty.

In Ontario, gas technicians are licensed through the Technical Standards and Safety Authority (TSSA), and gas work must meet the province’s gas installation code. Most GTA municipalities, including Toronto, may also require a building permit. Our licensed technicians handle the installation, testing and any required permits for you.

If your furnace is over 15 years old and the repair cost is more than about half the price of a new one, replacement usually makes more sense. Frequent breakdowns and high gas bills also point toward replacing.

We’ll always give you an honest look at both options. If your furnace is relatively new and the repair is simple, fixing it usually makes sense. If it’s old and inefficient, a new furnace can lower your bills and give you years of reliable heat.

A furnace burns fuel to create heat. A heat pump moves heat from the outdoor air into your home and can also cool in summer. Many homes pair the two in a hybrid system.

Each has advantages. Furnaces deliver very hot air quickly, even in extreme cold, while heat pumps are very efficient and provide air conditioning too. With current heat pump rebates, many homeowners are comparing both options.

Yes. In a hybrid or dual-fuel system, the heat pump handles heating for most of the year and the gas furnace takes over on the coldest days. It’s a popular option for GTA homes.

You can set the system to switch between the heat pump and furnace based on outdoor temperature or energy costs. It’s a flexible way to cut gas use while keeping strong backup heat for the coldest days.

A clogged filter, closed or blocked vents, leaky ductwork, a blower problem or an undersized furnace can all cause this. Start by checking the filter and vents, then call for service.

Older homes with long or leaky duct runs often lose a lot of heat before it reaches the rooms. If simple checks don’t solve it, our technicians can test airflow and recommend the right fix.

An ECM (electronically commutated motor) blower adjusts its speed to match demand. It uses less electricity, runs more quietly and helps even out temperatures between rooms.

Variable-speed blowers can also run at a low, quiet speed between heating cycles to keep air moving through your filter. They’re common in higher-end furnaces and pair well with air conditioners and heat pumps.

A light dusty or burning smell for a few minutes at the start of the heating season is normal, as dust burns off the heat exchanger. A strong, lasting burning, electrical or gas smell is not normal.

Change your filter before the first cold day of the season to cut down on that dusty smell. If you notice a strong smell that doesn’t go away, turn the furnace off and call for service.

Usually not. Closing too many vents can raise pressure in the ductwork, reduce airflow and make your furnace work harder. If some rooms are too warm or cold, ask about duct balancing or zoning.

Your system is designed to move a certain amount of air. Instead of closing vents, we can help balance your ducts, add zoning or recommend a ductless unit for the rooms that are hard to heat or cool.

The heat exchanger keeps combustion gases separate from the air you breathe. A cracked heat exchanger can let carbon monoxide escape, so a furnace with a confirmed crack should be shut down and repaired or replaced.

Heat exchanger cracks are most common in older furnaces and can be hard to see. That’s one reason annual inspections matter, and why working CO alarms are so important in every home with a gas furnace.

Most manufacturers offer a parts warranty, often around 10 years when the furnace is registered. Labour coverage varies by installer, so ask what’s included in your quote.

Registering your furnace with the manufacturer soon after installation is important, because many offer longer coverage only to registered products. Keep your installation paperwork and maintenance records together in case you ever need to make a claim.

The price depends on the furnace size, efficiency, features, venting and any ductwork changes. We offer free in-home consultations so you get an accurate quote for your home.

Prices for GTA homes depend on the furnace size, efficiency, venting and any ductwork changes, plus permits where your municipality requires them. We offer free in-home consultations across Toronto, Markham, Richmond Hill and the GTA, and financing options to spread out the cost.

Natural Resources Canada suggests about 20°C when you’re home and awake, and a few degrees lower while you sleep or are away. A programmable or smart thermostat makes this automatic.

Every degree you lower the temperature while you’re asleep or away can help reduce your heating costs. If you have a heat pump, keep setbacks small, since big swings can make the system work harder to recover.

You can. Running the fan continuously improves air circulation and filtration, but it uses more electricity and can make the air feel cooler. Most homeowners keep it on Auto.

If you choose to run the fan constantly, a furnace with a variable-speed blower is much more efficient at it. Pairing continuous fan with a good filter or air purifier can noticeably improve indoor air quality.

A heat pump is an electric system that moves heat instead of creating it. In winter it pulls heat from the outdoor air into your home, and in summer it works in reverse to cool your home like an air conditioner.

Because heat pumps move heat instead of burning fuel, they can deliver more energy as heat than they use in electricity. That’s what makes them so efficient, and why they’re at the centre of many government rebate programs.

Yes. Today’s cold-climate heat pumps are designed to keep heating efficiently well below freezing, and many keep producing heat in temperatures around -25°C to -30°C.

Toronto’s winter design temperature is around -20°C, and most GTA winter days are much milder than that, which is where heat pumps are most efficient. Cold-climate models are built for these conditions, and many GTA homeowners keep their gas furnace as backup for the coldest stretches.

A cold-climate heat pump is built to deliver strong heating performance at low outdoor temperatures. These models use variable-speed (inverter) compressors and are tested for cold-weather output.

Not every heat pump is a cold-climate model. When you’re comparing systems, look at how much heating capacity it keeps at low temperatures, not just its efficiency rating. We’ll help you compare models side by side.

A ducted heat pump connects to your home’s existing ductwork, much like a central air conditioner. A ductless heat pump uses wall-mounted or ceiling units in individual rooms, so no ductwork is needed.

Ducted systems heat and cool the whole home through your existing vents. Ductless systems are ideal for homes without ducts, additions, basements or rooms that are hard to keep comfortable. Some homes use both.

Air-source heat pumps exchange heat with the outdoor air and are the most common choice. Ground-source (geothermal) heat pumps use buried loops in the ground. They’re very efficient but cost much more to install.

For most GTA homes, an air-source heat pump offers the best balance of cost and performance. Geothermal systems need space for drilling or trenching, which makes them more practical for larger properties or new builds.

In many homes, yes, with a properly sized cold-climate system. Many GTA homeowners choose to keep their furnace as a backup for the coldest days. We’ll help you decide what fits your home.

Whether a heat pump can handle all of your heating depends on your home’s heat loss, insulation and the system you choose. During a free consultation, we look at your home and recommend whether a full replacement or hybrid setup makes more sense.

A hybrid system pairs a heat pump with a gas furnace. The heat pump heats your home for most of the year, and the furnace automatically takes over during extreme cold.

The switch between the two can be set by outdoor temperature or by energy cost. A hybrid system lets you use less natural gas while keeping reliable, strong heat during the coldest stretches of winter.

It depends on what you heat with today. Homes switching from electric baseboards, oil or propane usually see the biggest savings. Switching from natural gas may not always lower bills, depending on your home and energy prices.

Most GTA homes heat with natural gas from Enbridge Gas, and how a heat pump compares depends on current gas and electricity rates and your home. Homes heating with electric baseboards, oil or propane usually see the biggest savings. We’ll give you an honest estimate for your home.

SEER2 measures cooling efficiency and HSPF2 measures heating efficiency. Higher numbers mean a more efficient heat pump. These ratings use updated testing that better reflects real-world conditions.

When comparing heat pumps, look at heating performance in cold weather too, not just SEER2. A system with a strong low-temperature rating will keep your home comfortable through a GTA winter.

The right size comes from a load calculation that looks at your home’s insulation, windows, air leakage and layout. Proper sizing is especially important for heat pumps, so they heat well in winter without short-cycling in summer.

An oversized heat pump short-cycles in mild weather, which reduces comfort and dehumidification. An undersized one may need more help from backup heat in winter. We size every system to your home’s actual needs.

Most heat pumps last 15 to 20 years with regular maintenance. Because they run in both summer and winter, yearly service is important.

Keeping the outdoor unit clear of snow, ice and debris, changing filters regularly and booking yearly service all help a heat pump reach a long, efficient lifespan.

Air from a heat pump feels warm but not as hot as a furnace, which is normal. During a defrost cycle it may briefly blow cooler air. If the air stays cold, check the thermostat and filter, then call for service.

Heat pumps deliver a steady stream of warm air, often around 30°C to 40°C at the vents, rather than short bursts of very hot air. Your home stays comfortable, even if the air doesn’t feel as hot on your hand.

In cold, damp weather, frost builds up on the outdoor coil. The heat pump periodically runs a short defrost cycle to melt it. You may see steam and hear a whoosh, and that’s normal.

Defrost cycles are more frequent in damp weather around freezing. During defrost, the outdoor fan usually stops and the system briefly reverses. It then switches back to heating automatically.

Steam usually means the heat pump is in defrost mode, melting frost off the outdoor coil. It typically lasts a few minutes and is part of normal winter operation.

Steam is especially common on cold, humid mornings. If you see smoke, smell burning or hear grinding noises, turn the system off and call us right away.

A light layer of frost that clears during defrost is normal. Thick ice that covers the unit or doesn’t clear can mean a defrost, airflow or drainage problem, so call for service.

Ice can build up if the unit is sitting in snow, if water from the roof is dripping onto it, or if there’s a mechanical problem. Never chip ice off the coil with tools, since it’s easy to damage the fins.

It needs good airflow, clearance from walls and shrubs, and protection from roof runoff and dripping eaves. In the GTA it should sit above the expected snow line on a stand or wall bracket.

In Toronto and the GTA, we plan for snow, roof runoff and ice from eaves, and we keep the unit above the expected snow line on a stand or wall bracket. In tight downtown side yards and semi-detached homes, we also consider noise for you and your neighbours.

In most GTA locations, yes. A stand or wall bracket keeps the outdoor unit above snow and lets melt water drain away during defrost, which protects performance.

GTA winters bring snow, freezing rain and freeze-thaw cycles, so a stand or wall bracket keeps the outdoor unit clear of snow and lets defrost water drain away. Raising the unit also protects it from ice that can form underneath and block airflow.

Modern inverter heat pumps are quiet. Outdoor units are often similar to a normal conversation or quieter, and indoor units are very quiet. You may hear a brief whoosh during defrost.

Indoor units of ductless systems are especially quiet, and outdoor units often run at low speeds most of the time. Good placement and a solid mount help keep noise to a minimum.

Yes. We recommend a professional service once a year. Between visits, keep filters clean and keep the outdoor unit clear of snow, ice, leaves and debris.

A maintenance visit includes checking refrigerant levels, cleaning coils, testing electrical parts and controls, checking the defrost cycle and clearing drains. Regular service also helps protect your warranty.

Often, yes. We check your ductwork’s size and condition first, since heat pumps typically need good airflow to perform well. Some homes need minor duct changes.

If your existing ducts are too small or in poor condition, we may recommend upgrades or a ductless system for certain areas. We’ll explain any duct work clearly before you decide.

Sometimes. It depends on your panel’s capacity and what else is on it, such as an EV charger or electric range. We assess your panel during the free consultation.

Many older Toronto homes still have 60- or 100-amp electrical service, which may not leave enough room for a heat pump. If an upgrade is needed, it’s coordinated with your local utility, such as Toronto Hydro or Alectra Utilities. We assess your panel during the free consultation.

Most standard installations are completed in a single day. Larger systems, hybrid setups or jobs that need electrical upgrades can take longer.

We’ll give you a clear timeline before we start. On installation day, our team protects your home, installs and tests the system, cleans up and shows you how to use your new heat pump and thermostat.

Yes. Canada’s National Heat Pump Rebate offers up to $10,000 for households at or below the median income, and $2,000 for households above it. Visit our Heat Pump Rebate page for full details.

GTA homeowners in Toronto, Markham, Richmond Hill and across Ontario can use the National Heat Pump Rebate. To qualify, the heat pump must be on the program’s eligible product list, heat your whole home and be installed by an HVAC contractor. We’ll confirm your system’s eligibility before you buy.

Manufacturer warranties vary by brand and model. As a Mitsubishi Electric Residential Summit Dealer, we can offer a 12-year parts and compressor warranty on qualifying Cold Climate Hyper-Heat installations.

Warranty terms can depend on registering the equipment and keeping up with maintenance. We’ll walk you through exactly what’s covered for the system you choose.

HRAI is the Heating, Refrigeration and Air Conditioning Institute of Canada. Spring Home is recognized as an HRAI Heat Pump Champion for our heat pump expertise.

It means our team has the training and experience to design and install heat pumps properly. That matters, because a heat pump’s performance depends heavily on correct sizing, placement and setup.

Heat pumps work best with a steady setting. Big setbacks can make the system work harder or call on backup heat to recover. Small setbacks of a degree or two are usually fine.

Most heat pumps are most efficient when they hold a consistent temperature. A smart thermostat designed for heat pumps can help manage this automatically while keeping your home comfortable.

In cooling mode they work the same way. The difference is that a heat pump has a reversing valve, so it can also heat your home in winter.

That means one heat pump can replace your air conditioner and provide much of your heating. If you’re replacing an aging air conditioner anyway, it’s worth comparing the cost of a heat pump.

New systems are moving to lower-impact refrigerants such as R-454B and R-32, replacing R-410A under updated Canadian rules. Your installer will match the right refrigerant to your equipment.

Refrigerant rules are changing to reduce environmental impact. If your current system uses an older refrigerant, it may be harder and more expensive to repair as time goes on.

Yes, as long as the thermostat supports heat pumps. Some ductless and variable-speed systems work best with the manufacturer’s own controls. We’ll recommend the right option.

Using the right thermostat matters with heat pumps, because it controls defrost, backup heat and staging correctly. The wrong thermostat can cause higher bills or comfort problems.

Like a furnace, a heat pump needs power to run. If outages are a concern, ask about backup heat or a backup power solution.

GTA homeowners still remember outages like the 2013 Toronto ice storm. If outages are a concern, keeping your gas furnace as backup heat, or adding a standby generator, gives you more security. We can talk through options during your consultation.

A properly sized cold-climate heat pump can heat a whole home. Whole-home heating is also a requirement for the National Heat Pump Rebate, so sizing matters.

Whole-home heating usually means the system can heat all the main living areas, not just one room. We’ll size and design your system with that in mind.

Yes. You don’t have to remove your existing furnace. Many homeowners keep it as backup heat in a hybrid system.

Keeping your furnace gives you a backup heat source and lets you set up an efficient hybrid system. The furnace can also run the blower for your ducted heat pump.

Most central air conditioners last 12 to 15 years. Annual maintenance and a clean outdoor coil help them last longer.

Coastal or very hot climates shorten AC life, but in the GTA most systems reach that range with good care. If your system is over 12 years old, it’s worth planning ahead rather than waiting for it to fail during a heat wave.

The right size comes from a cooling load calculation, not just square footage. Air conditioners are sized in tons, where one ton equals 12,000 BTUs per hour. An oversized unit cools quickly but leaves the air clammy.

GTA summers are hot and humid, with Humidex values that can climb into the high 30s, so the right size matters for removing moisture as well as heat. An oversized unit cools quickly but leaves the air clammy. We size every system with a proper cooling load calculation.

SEER2 measures an air conditioner’s cooling efficiency over a typical season. The higher the number, the less electricity it uses to cool your home.

Higher-SEER2 systems usually cost more upfront but use less electricity every summer. We’ll help you find the balance between purchase price and long-term savings that suits your home.

Check the thermostat setting, the breaker and the filter first. A dirty outdoor coil, a refrigerant leak, a failed capacitor or a frozen indoor coil can also stop cooling. Call for service if the basics look fine.

Make sure all vents are open and the outdoor unit isn’t blocked by plants, leaves or debris. If the system runs but blows warm air, turn it off to protect the compressor and call us.

Ice on the indoor coil or refrigerant line usually means low airflow from a dirty filter or blocked vents, or low refrigerant from a leak. Turn cooling off, run the fan to thaw it, and call for service.

Running the system while it’s frozen can damage the compressor. Once it’s thawed, replace the filter and check for blocked vents. If it freezes again, there’s likely a refrigerant or airflow problem that needs a technician.

The most common cause is a clogged condensate drain line. A cracked drain pan, a failed condensate pump or a frozen coil that melts can also cause leaks.

Leaks can damage ceilings, floors and drywall, so shut the system off if water is pooling. A technician can clear the drain, check the pump and make sure the coil isn’t freezing.

Once a year, ideally in the spring before hot weather arrives. Regular service keeps it efficient and helps prevent breakdowns during heat waves.

In the GTA, book your AC tune-up in April or May, before the first heat wave. Service schedules fill up fast once Toronto hits its first 30°C day, so booking early helps you avoid waiting during peak season.

A tune-up typically includes cleaning the outdoor coil, checking refrigerant levels, testing electrical parts and the capacitor, clearing the condensate drain, checking airflow and the filter, and confirming the system cools properly.

A tune-up also gives our technician a chance to spot wear on parts like the fan motor or contactor. Catching these early can prevent a breakdown on the hottest day of the year.

A breathable cover over just the top can keep ice and debris out. Avoid wrapping the whole unit tightly, since that can trap moisture and attract rodents.

Before using your AC in spring, remove any cover and clear away debris around the unit. Always make sure power is off before cleaning near the outdoor unit.

During a heat wave, long run times can be normal. If it runs nonstop in mild weather, a dirty coil, low refrigerant, leaky ducts or an undersized system could be the cause.

An air conditioner that never shuts off may also be low on refrigerant or struggling with a failing part. If it’s running nonstop and the house still isn’t comfortable, book a service call.

If your system is over 12 years old, needs a costly repair or uses R-22 refrigerant, replacement is usually the better value. A newer system will also use much less electricity.

We’ll give you an honest repair-versus-replace recommendation. For a newer system with a simple problem, repair usually makes sense. For an older or inefficient system, replacement often saves money over time.

R-22 has been phased out in Canada, so repairs that need refrigerant are expensive. If your system needs a major repair, replacing it with a modern air conditioner or heat pump is usually the smarter choice.

Older R-22 systems are also usually much less efficient than today’s equipment. Planning a replacement before a major failure gives you more choice and avoids an emergency purchase in peak season.

It often makes sense. A matched system works more efficiently, you only have one installation, and both units start fresh with new warranties.

Your furnace’s blower moves the cooled air through your home, so the two systems work together. Matching them helps your new air conditioner reach its rated efficiency and comfort.

Natural Resources Canada suggests about 25°C when you’re home and a few degrees higher when you’re away. Every degree higher saves energy.

Avoid setting the thermostat very low when you get home. Your air conditioner won’t cool faster, it will just run longer. A programmable or smart thermostat can start cooling before you arrive.

Buzzing can point to an electrical part such as the capacitor or contactor, rattling to loose panels or debris, and squealing to a fan motor. Grinding or screeching should be checked right away.

Some humming and a soft whoosh of air are normal. Loud or new sounds usually mean a part is failing, and getting it checked early can prevent a bigger repair.

A musty smell usually comes from mould or mildew on the indoor coil or in the drain pan. A professional cleaning helps, and a UV light can help prevent it from coming back.

Changing your filter regularly and keeping the condensate drain clear also help prevent smells. If you notice a burning or electrical smell, turn the system off and call right away.

Yes. A ductless mini split adds efficient cooling, and heating, to homes or rooms without ductwork.

That makes ductless a popular choice for older Toronto homes, semis and houses with radiators that never had central air. Ductless systems also provide efficient heat in winter, which can help reduce how much your furnace or boiler runs.

A heat pump cools just like an air conditioner but can also heat your home in winter. With current heat pump rebates, many homeowners find a heat pump is the better long-term choice.

Heat pumps cost a bit more than an air conditioner alone, but they can reduce how much your furnace runs in spring, fall and milder winter days. We’ll help you compare options.

Common causes are poor airflow, ductwork that isn’t balanced, extra sun through windows, or poor insulation. Duct balancing, zoning or a ductless unit for that room can help.

Second floors and rooms over garages are common trouble spots. Our technicians can measure airflow and suggest the most effective fix for your home.

Most central air conditioner installations are completed in one day. Adding new ductwork or a new furnace at the same time can extend the job.

On installation day, we remove the old unit, install and connect the new outdoor and indoor coil, test the system and show you how to use it.

Yes. As your air conditioner cools, it also pulls moisture out of the air, which makes your home feel more comfortable.

That’s especially important in Toronto, where muggy summer days make homes feel sticky. Systems that are oversized or short-cycling don’t run long enough to dehumidify well, which can leave the air feeling damp even when it’s cool.

It’s often a failed capacitor or fan motor. Turn the system off to protect the compressor and call for service.

Running the system without the outdoor fan can overheat the compressor. A capacitor replacement is often a quick and affordable fix when caught early.

A failing capacitor, a struggling compressor, a dirty coil or a wiring problem can all cause this. Don’t keep resetting the breaker. Call a technician.

A breaker that trips repeatedly is a sign of a real problem. Continuing to reset it can damage the system or create a safety risk.

Close blinds on sunny windows, keep the filter clean, keep the outdoor unit clear of debris, and avoid using heat-producing appliances during the hottest part of the day.

Ceiling fans also help you feel cooler without lowering the thermostat. Turn them off when you leave the room, since fans cool people, not spaces.

The price depends on the size, efficiency and features you choose, and on any changes your ductwork or electrical needs. We offer free in-home consultations so you get an accurate quote.

Prices for GTA homes depend on the size, efficiency and features you choose, and any electrical or ductwork changes. We offer free in-home consultations across Toronto, Markham, Richmond Hill and the GTA, and financing options to spread out the cost.

Usually, yes, if your furnace is in good shape and its blower can handle the airflow the new air conditioner needs. If your furnace is near the end of its life, replacing both together often makes more sense.

If your furnace is near the end of its life, replacing both together often makes more sense. We’ll look at your furnace’s condition during the consultation and recommend what’s best.

A ductless mini split is a heat pump with an outdoor unit connected to one or more indoor units by a small line set. It heats and cools individual rooms without ductwork.

The outdoor unit sits outside on a stand or wall bracket, and the indoor units mount on walls, ceilings or floors. Because there are no ducts, there’s no energy lost through leaky ductwork.

A single-zone system has one outdoor unit and one indoor unit. A multi-zone system connects several indoor units to one outdoor unit, so you can control different rooms separately.

Multi-zone systems are great for homes where different rooms need different temperatures, such as a cool bedroom and a warmer living area. Each indoor unit has its own controls.

They’re ideal for homes without ductwork, additions, finished basements, sunrooms, garages, home offices and rooms that are always too hot or cold.

In the GTA, they’re especially popular in older Toronto homes with radiators, semi-detached homes, laneway suites, finished basements and third-floor rooms that are always too hot in summer.

Yes. A mini split is a heat pump, so it heats in winter and cools in summer. Cold-climate models keep heating efficiently in very cold weather.

Cold-climate mini splits are designed for winters like Toronto’s, where the winter design temperature is around -20°C. Using a mini split for heating can reduce how much your furnace, boiler or baseboards run.

It depends on your layout and how you use each space. Open areas may need one unit, while closed-off rooms often need their own. We’ll design the right setup for your home.

Each indoor unit needs to be sized for the space it serves. Putting one large unit in a central area doesn’t always reach bedrooms or rooms with closed doors.

Options include high-wall units, ceiling cassettes, floor consoles and concealed ducted units. We’ll help you choose a style that suits each room.

High-wall units are the most common and affordable. Ceiling cassettes and floor consoles suit certain rooms better, and concealed ducted units can hide the equipment completely.

Usually about 3 inches across. It’s sealed and finished, and the line set can be hidden behind a neat cover on the outside.

The hole carries the refrigerant lines, drain line and power cable. We seal it properly to keep out drafts, water and pests.

A single-zone system is often installed in one day. Multi-zone systems can take one to three days depending on the number of rooms.

We’ll plan the layout with you beforehand so there are no surprises. On installation day, we protect your home, install the units, test the system and show you how to use it.

Rinse or vacuum the indoor unit filters every 2 to 4 weeks, especially during heavy use. Clean filters keep airflow strong and the air fresh.

Clogged filters reduce airflow and efficiency and can cause odours or leaks. Most filters slide out easily and can be rinsed with water and left to dry.

Yes. Plan on a professional cleaning and inspection once a year. This includes the indoor coils, blower wheel, drain and outdoor unit.

Indoor coils and blower wheels can collect dust and mould that filters don’t catch. A deep cleaning keeps the system efficient and the air fresh.

The usual causes are a clogged drain line, a dirty filter, or an indoor unit that isn’t mounted level. Turn it off and call for service if water keeps dripping.

A mini split that isn’t draining properly can also lead to mould inside the unit. Getting the drain cleared quickly protects your walls and floors.

A blinking light usually signals an error code or a filter reminder. Check your owner’s manual for the meaning, then call us if it’s an error.

Note the pattern of the blinking lights before calling us, since it helps our technician diagnose the problem. Sometimes turning the unit off and on clears a temporary error.

Mould can grow on the coil or blower wheel inside the indoor unit. A professional deep cleaning removes it, and regular filter cleaning helps prevent it.

Leaving the unit off for long periods in humid weather can also contribute to odours. Running it in fan or dry mode for a while can help keep it fresh.

Yes. They use inverter compressors that adjust their speed to demand, and there are no duct losses. That makes them one of the most efficient ways to heat and cool.

Inverter technology means the system doesn’t constantly turn on and off. It runs steadily at the speed needed, which keeps temperatures even and saves energy.

Often, but you’ll usually need approval from your condo board for the outdoor unit location and wall penetration. We can help you with the technical details they ask for.

Toronto condo boards often have rules about outdoor unit locations, balcony mounting and drilling through exterior walls. Getting approval before scheduling saves time. We can provide the equipment details and installation plans your board asks for.

They’re very quiet. Indoor units are often barely noticeable on low settings, and outdoor units are generally quieter than a standard central air conditioner.

Most of the noise comes from the outdoor unit, which we place carefully to reduce noise inside and for neighbours.

Yes. A multi-zone outdoor unit can connect to several indoor units, depending on the model’s capacity.

Multi-zone systems save space outside, since you need fewer outdoor units. We’ll make sure the outdoor unit has enough capacity for all the rooms it serves.

Many models offer Wi-Fi control through the manufacturer’s app, either built in or with an add-on adapter.

App control lets you adjust settings, set schedules and switch modes from anywhere. Some systems also connect to smart home devices.

They can, if the system is on the eligible product list and can heat your whole home. A single unit for one room may not qualify. We’ll confirm before you buy.

Rebate rules can change, so we always check the current requirements before you buy. If you’re planning a larger heat pump project, we’ll design it with rebate eligibility in mind.

Yes. We use line set covers that run neatly along the wall and can often be painted to match your home.

Line set covers protect the refrigerant lines from sun and weather, and they give your installation a clean, professional look.

With regular cleaning and maintenance, most last 15 to 20 years.

Regular filter cleaning and yearly professional maintenance help ductless systems reach a long lifespan.

If your home has good ductwork, a ducted heat pump may be simpler. If you don’t have ducts, or only need to fix certain rooms, ductless is often the better fit.

We’ll look at your existing ductwork, the rooms that need help and your budget, then recommend the system that makes the most sense.

With properly sized cold-climate units, many homes can rely on mini splits for most or all of their heat. Some homeowners keep another heat source as backup.

Proper sizing and placement are key if you want to rely on mini splits for most of your heat. We’ll design a system that can handle GTA winters.

Dry mode removes humidity with minimal cooling. It’s useful on damp spring and fall days.

Dry mode is helpful in basements and during humid weather when you don’t need much cooling. It removes moisture while keeping temperatures comfortable.

Most tank water heaters last 8 to 12 years. Hard water, high usage and skipped maintenance can shorten that.

Annual flushing helps remove sediment, which keeps a tank working efficiently. If your tank is near the end of its life, planning a replacement helps you avoid a sudden leak.

Tankless water heaters often last 15 to 20 years or more with regular descaling and maintenance.

Because tankless units only heat water when you need it, they avoid standby heat losses from a tank. Regular descaling is the key to reaching their full lifespan.

A tank water heater stores and keeps a supply of hot water warm. A tankless unit heats water on demand as it flows through, so it saves space and won’t run out, but is limited by flow rate.

Tanks cost less upfront and work well for many homes. Tankless units cost more but save space, can last longer and provide continuous hot water. We’ll help you decide based on your household’s needs.

Watch for rusty or discoloured hot water, water around the base, rumbling noises, not enough hot water, or a tank that’s over 10 years old.

Water heaters often fail with little warning. Replacing an aging tank before it leaks can save you from water damage and an emergency replacement.

For gas units, check the gas supply and whether the pilot or ignition has gone out. For electric units, check the breaker. A failed thermostat, burner or venting safety switch can also cause it.

If you have a power-vented unit, a blocked vent or a tripped safety switch can also shut it down. Don’t try to relight a gas water heater if you smell gas. Leave the home and call your gas utility.

Sediment buildup, a broken dip tube, a faulty thermostat or a tank that’s too small for your household can all reduce hot water supply.

In winter, incoming water is colder, so your water heater has to work harder. If your hot water supply has shrunk over time, it’s worth having the unit checked.

That’s usually sediment at the bottom of the tank. Water trapped under the sediment boils and pops. Flushing the tank helps, but heavy buildup can mean it’s time to replace.

Sediment also makes your water heater work harder and less efficiently. Regular flushing helps keep it quiet and extends its life.

Bacteria in the tank can react with the anode rod and create a sulphur smell. Flushing the tank and replacing the anode rod usually fixes it.

If the smell only comes from hot water, it’s likely the water heater. If both hot and cold water smell, the issue may be in your water supply.

Once a year for most tank water heaters. In hard-water areas, more often helps prevent sediment buildup.

GTA water from Lake Ontario is moderately hard, so sediment builds up in tanks over time. Our technicians can flush your tank and check the anode rod and safety valve at the same time.

A tank temperature of about 60°C helps prevent bacteria such as Legionella. Anti-scald mixing valves can then lower the temperature at your taps to reduce the risk of burns.

Higher temperatures increase scald risk, especially for young children and older adults. A mixing valve lets you store water hot enough to limit bacteria, while delivering safer water at your taps.

Turn off the cold water supply to the tank and turn off the gas or power. Then call for service. A leaking tank usually needs replacement.

Place towels or a bucket to catch water and move valuables away. For a gas water heater, if you smell gas, leave your home and call the Enbridge Gas emergency line at 1-866-763-5427. Then call us to replace the unit.

The temperature and pressure relief valve opens when pressure or temperature gets too high. Frequent dripping can mean high water pressure, a missing expansion tank or a faulty valve, and should be checked.

Never cap or block the relief valve. It’s an important safety device. If it’s leaking, have a technician check the cause.

Most households use 40 to 60 gallons. Size depends on the number of people, bathrooms and how much hot water you use at peak times.

Your plumbing fixtures, showers and appliances affect the right size too. A tank that’s too small runs out quickly, while one that’s too large wastes energy.

Tankless units are sized by flow rate in gallons per minute and how much the water needs to be heated. We look at how many fixtures you run at once.

If you often run multiple showers at once, you may need a larger tankless unit. We’ll size it for your household’s peak use.

Yes. It should be descaled regularly, typically once a year, to remove mineral buildup, especially with hard water.

GTA tap water from Lake Ontario is moderately hard, so minerals build up inside tankless heat exchangers over time. Descaling keeps the unit efficient and helps prevent error codes and shutdowns.

It won’t run out the way a tank does, but it can only heat so much water at once. Running several showers and appliances together can exceed its capacity.

Using fixtures one after another, rather than all at once, helps a tankless unit keep up. Proper sizing makes sure it can handle your typical usage.

Conventional units vent through a chimney. Power-vented units use a fan to vent through a wall. Direct-vent units draw air from and vent outside without a fan.

The type of venting affects where your water heater can go and what a replacement involves. We’ll match the right type to your home.

Buying usually costs less over the life of the unit, while renting bundles repairs into a monthly fee. We’ll explain the options so you can choose.

Many Ontario homes rent their water heater from companies like Enercare or Reliance. Buying usually costs less over the life of the unit, while renting bundles repairs into a monthly fee. We’ll explain the options so you can choose.

Usually, yes. Check your rental agreement for any buyout or return terms first. We can then install a new unit that you own.

If you rent from a company like Enercare or Reliance, check your agreement for buyout or return terms first, since some contracts include fees. We can then install a new water heater that you own and help with returning the old unit.

Most replacements are done in a few hours, often the same day you call.

Switching from a tank to tankless can take longer, since it may involve new venting, gas line or electrical changes.

A combi boiler provides both space heating and on-demand hot water from one compact unit, so you don’t need a separate tank.

Combi boilers save space and work well in homes with radiators or in-floor heating. They’re sized for both your heating and hot water needs.

A heat pump water heater moves heat from the surrounding air into the water. It’s very efficient but needs enough space and air around the unit to work well.

Heat pump water heaters work best in spaces that stay above a certain temperature, such as a basement or utility room. They also cool and dehumidify the space around them.

Rusty hot water often means the tank is corroding inside or the anode rod is worn out. It’s usually a sign replacement is coming.

Rusty water can also come from old galvanized pipes. If the rust only appears in hot water, the water heater is the likely source.

Many homes need one, especially with a backflow preventer or closed plumbing system. It absorbs pressure as water heats and protects your tank and plumbing.

Without an expansion tank, pressure can build up and cause the relief valve to drip or put stress on your plumbing. Some local codes require one.

The longer the pipe run from the water heater, the longer the wait. A recirculation pump can deliver hot water faster.

Insulating hot water pipes can also help water stay hot as it travels. A recirculation system saves water by reducing the time you wait for hot water.

This is sometimes called a cold water sandwich. It happens when water left in the pipes cools between uses. It’s normal and usually lasts only a few seconds.

Some tankless units have features that reduce this effect. Waiting a moment before stepping into the shower usually avoids it.

A boiler heats water and circulates it through radiators, baseboards or in-floor tubing to heat your home. It’s often called hydronic heating.

Boilers are common in older Toronto neighbourhoods, where many homes still heat with radiators, and in newer homes with radiant floor heating. Hydronic heating is known for quiet, even comfort and no blowing air.

A furnace heats air and blows it through ducts. A boiler heats water that delivers heat through radiators or floors, which many people find quieter and more even.

Boilers don’t move dust around the way forced air can, which some people prefer for allergies. However, adding air conditioning to a boiler-heated home usually requires a separate system.

Most boilers last 15 to 30 years depending on the type, water quality and maintenance.

Cast-iron boilers can last a very long time, while high-efficiency condensing boilers typically last 15 to 20 years. Annual service helps any boiler reach its full lifespan.

A condensing boiler captures heat from its exhaust gases, reaching efficiencies of 90% or more. Older non-condensing boilers are often far less efficient.

Condensing boilers work best with lower return water temperatures, which suits radiant floors and properly sized radiators. They vent through the side of your home with plastic piping.

Kettling often comes from scale or sediment on the heat exchanger, which makes water boil in spots. Banging can also be trapped air or a circulation issue. Both should be checked.

Ignoring kettling can reduce efficiency and damage the heat exchanger over time. A technician can flush or descale the system and check the pump.

That usually means air is trapped in the radiator. Bleeding the radiator releases the air and lets hot water fill it.

If several radiators are cold, the issue may be the pump, a valve or low system pressure. Bleeding the air out of the system usually solves cold spots at the top.

With the heating off, open the bleed valve with a radiator key and a cloth ready. Close it once water starts to come out, then check your boiler pressure.

Bleeding radiators releases trapped air so hot water can fill them. If you need to bleed radiators often, there may be a leak or another problem in the system.

Most residential hydronic systems run at roughly 12 to 20 psi, but your system may differ. If the gauge is outside the range your installer set, call for service.

Low pressure can mean a leak or that air has been bled from the system. High pressure can mean a problem with the expansion tank or fill valve.

Leaks can come from a failed pressure relief valve, loose fittings, a worn pump seal or corrosion. Turn the boiler off and call a technician.

Don’t ignore a leaking boiler, since water and electrical parts don’t mix. A small leak can also become a larger one.

Once a year, ideally before the heating season. Service includes checking the burner, controls, pressure, pump, venting and safety devices.

Regular service keeps your boiler running safely and efficiently. It also helps you avoid breakdowns during the coldest part of winter.

Follow the lighting instructions on the unit if you’re comfortable. If it won’t stay lit or goes out repeatedly, call for service, since it may be a thermocouple, gas or venting issue.

Never try to relight a boiler if you smell gas. Leave your home and call your gas utility from outside.

Older cast-iron boilers can be very inefficient. A new high-efficiency condensing or combi boiler can use much less gas and save space.

Many older Toronto homes still have cast-iron boilers that are decades old. Replacing one also gives you a chance to add better controls, zoning or indirect hot water. We’ll design a system that fits your home and budget.

Yes. Boilers work well with zoning, using separate thermostats and valves or pumps to control different areas of your home.

Zoning lets you keep bedrooms cooler and living areas warmer, or turn down rooms you don’t use often. It can improve comfort and reduce energy use.

Yes. Boilers are a common heat source for hydronic radiant floor heating.

A boiler can supply both radiators and radiant floors, with controls that deliver the right water temperature to each.

Most boiler replacements take one to three days, depending on the system and any piping changes.

The timeline depends on how much piping needs to change and whether venting must be updated. We’ll give you a clear plan before work begins.

Short cycling can be caused by an oversized boiler, thermostat problems, low water pressure or a faulty control. It wastes energy and should be checked.

Short cycling wastes energy and wears out parts faster. A properly sized boiler with the right controls runs longer, steadier cycles.

Yes. Ductless mini splits and high-velocity systems are popular ways to add cooling to homes heated by a boiler.

This is one of the most common questions we hear from owners of older Toronto homes with radiators. Ductless systems are popular because they add both cooling and efficient heating without ductwork.

Many systems benefit from water treatment to prevent scale and corrosion, which helps the boiler last longer. We can check this during service.

Treated water helps protect metal parts inside the boiler and system from scale and corrosion, extending their lifespan.

Radiant floor heating warms your home from the floor up, using hot water tubing or electric cables under the floor. It delivers quiet, even heat without blowing air.

Because radiant heat warms surfaces directly, rooms often feel comfortable even at a slightly lower air temperature. It’s especially popular in bathrooms, basements and kitchens.

Hydronic systems circulate warm water through tubing and suit larger areas or whole homes. Electric systems use heating cables and are popular for bathrooms and small spaces.

Hydronic systems cost more to install but are usually cheaper to run over large areas. Electric systems are simpler to install, making them ideal for small renovations.

Yes. Hydronic radiant systems can heat an entire home, often paired with a boiler or another hot water source.

Whole-home radiant heating works best when it’s planned into a new build or major renovation. It can be paired with a separate system for cooling and fresh air.

Often, yes. It’s easiest during renovations, in basements or when new flooring is going in. Some systems can also be installed from below the floor.

Retrofits can be more involved than new installs. We’ll look at your floors, access and heat source to see what’s practical.

Tile and stone work best because they conduct heat well. Many engineered wood and vinyl floors also work. Thick carpet and underlay reduce performance.

The flooring manufacturer’s guidelines matter, since some floors have temperature limits. We’ll help you choose a setup that suits your flooring.

It can be. Radiant systems work at lower water temperatures and heat people and objects directly, so many homes feel comfortable at a slightly lower thermostat setting.

Radiant heating also avoids the duct losses that forced-air systems can have, and it doesn’t stir up dust.

Radiant floors respond more slowly than forced air, especially in thick concrete slabs. They work best with a steady thermostat setting.

Thin systems installed under tile respond faster than tubing embedded in concrete. Smart controls can help schedule heat ahead of time.

Yes. An air-to-water heat pump can supply the lower water temperatures that radiant floors use.

Heat pumps work very efficiently with radiant floors because of the lower water temperatures involved. It’s a strong option for energy-efficient homes.

Hydronic systems need the same yearly service as the boiler or heat source that supplies them. Electric systems need very little maintenance.

Regular checks of the pump, controls and pressure help hydronic systems run smoothly. Electric systems usually only need thermostat checks.

Yes. Basements and garages with concrete slabs are well suited to radiant heat, which keeps floors warm and dry.

Basement apartments, laneway suites and heated garages are common in the GTA, and radiant heat keeps concrete floors warm and helps dry them out. It’s a comfortable choice for lower levels that tend to feel cold.

Standard radiant floors are for heating only. Pairing them with a ductless system or central air conditioner adds cooling.

Because radiant floors don’t use ducts, ductless systems are a natural way to add air conditioning.

Quality PEX tubing used in hydronic systems is designed to last for decades.

Well-installed tubing is protected inside the floor and rarely needs repair. The boiler or heat source will need replacing long before the tubing does.

Indoor air quality describes how clean and healthy the air inside your home is, including dust, allergens, humidity, odours and pollutants.

Indoor air can be more polluted than outdoor air, especially in airtight homes. Your HVAC system plays a big role in filtering, humidifying and ventilating the air you breathe.

Common signs include dust building up quickly, lingering odours, stuffiness, worsening allergies, headaches, window condensation and very dry or damp air.

If several of these sound familiar, a simple assessment of your filtration, humidity and ventilation can usually find the cause.

MERV rates how well a filter captures particles, from 1 to 16. Higher numbers capture smaller particles, but they can also restrict airflow if your system isn’t designed for them.

Higher-MERV filters capture more fine dust, pollen and smoke. Your system’s blower and filter rack need to handle them, or airflow can drop.

Many homes do well with MERV 8 to MERV 13. Ask us before switching to a higher rating, so your system’s airflow isn’t reduced.

Thicker media filters can offer high filtration with less airflow restriction than thin high-MERV filters. Ask us what your system can handle.

A whole-home air purifier works with your HVAC system to clean the air throughout your home, capturing fine particles and reducing allergens and odours.

Whole-home purifiers clean the air in every room your system serves, without the noise and clutter of portable units.

UV lights installed near the indoor coil help limit mould and bacteria growth on the coil and in the air passing by, which can help reduce odours.

UV lights are a good add-on in homes with humidity, allergy or odour concerns. They work best alongside regular filter changes and maintenance.

Aim for about 30% to 50% relative humidity. In very cold weather, keep it toward the lower end to avoid window condensation.

Too little humidity can cause dry skin and static, while too much can lead to condensation and mould. A hygrometer helps you keep track.

If your home feels dry in winter, with static shocks, dry skin or cracking wood floors, a whole-home humidifier can add comfortable moisture to the air.

Whole-home humidifiers connect to your furnace and water supply, so you don’t have to refill portable units. They need yearly maintenance to stay clean.

If your home or basement feels damp or musty in summer, a whole-home dehumidifier removes excess moisture and helps prevent mould.

GTA summers are humid, and many Toronto basements feel damp from June to September. A whole-home dehumidifier removes much more moisture than portable units and drains automatically.

Both bring in fresh outdoor air and exhaust stale air while recovering heat. An ERV also transfers some moisture, which helps balance humidity.

HRVs work well in most GTA homes. ERVs can be helpful in homes that get too dry in winter or too humid in summer.

Newer, tightly sealed homes often need one to bring in fresh air. Signs you may need one include stuffiness, lingering odours and window condensation.

Newer GTA homes built to recent Ontario Building Code standards are tightly sealed and usually include an HRV or ERV. Older homes that have been air-sealed during renovations can also benefit from added ventilation.

Not every year. Consider duct cleaning after renovations, if you see visible dust or debris coming from vents, after pests, or when moving into a home.

Duct cleaning is usually most helpful when there’s a clear reason, such as construction dust or debris. Keeping filters changed helps ducts stay cleaner.

It can help if your ducts are dirty, but good filtration and humidity control usually make the biggest difference for allergies.

For allergies, start with a higher-quality filter and keep humidity in check. Duct cleaning can be a helpful extra step if ducts are visibly dirty.

Use the highest MERV filter your system can handle, run the fan to keep air filtering, keep windows closed and consider a whole-home air purifier.

Toronto saw several days of poor air quality from wildfire smoke in recent summers. During smoke events, reduce fresh-air intake from your HRV or ERV, and consider portable purifiers in bedrooms for extra protection.

Indoor humidity is too high for the outdoor temperature. Lower your humidifier setting, run bathroom and kitchen fans and consider an HRV or ERV.

It’s common in GTA homes during cold snaps, when outdoor temperatures drop well below freezing. Lower your humidifier setting as it gets colder, run bathroom and kitchen fans and consider an HRV or ERV.

Cold winter air holds little moisture, and heating it makes it feel even drier. A whole-home humidifier can bring humidity back to a comfortable level.

Proper humidity also helps protect wood floors, furniture and musical instruments from drying out and cracking.

Keep humidity between 30% and 50%, use exhaust fans, fix leaks quickly, keep your HVAC drains clear and make sure your home is properly ventilated.

Pay extra attention to basements, bathrooms and around windows. If you see mould growing, address the moisture source first.

Yes. A better filter, a whole-home air purifier and regular filter changes all help reduce pet dander and hair in the air.

Regular brushing and vacuuming also help. A purifier can make a noticeable difference in homes with several pets.

Some technologies can reduce airborne particles that carry viruses, but no air purifier guarantees protection. They work best alongside good ventilation.

Good ventilation, filtration and humidity control all work together to keep indoor air healthier.

Check and clean them about every three months, and have the unit serviced once a year.

Dirty HRV filters reduce airflow and fresh air delivery. Many filters can be vacuumed or rinsed, while others need replacing.

A media filter cabinet holds a thicker 4- to 5-inch filter next to your furnace. It captures more particles than a standard filter and lasts much longer.

Media filters only need changing once or twice a year in most homes, which makes them convenient as well as effective.

Clean filters and coils help your system run efficiently, and proper humidity can make your home feel comfortable at a lower or higher thermostat setting.

An efficient system with clean filters runs less and uses less energy. Good humidity control can also help you feel comfortable at a more efficient setting.

Smart thermostats let you adjust your temperature from your phone, learn your schedule, use sensors for comfort in different rooms and help cut energy use.

Many smart thermostats also send maintenance reminders and alerts if something goes wrong. They’re a simple upgrade that can improve comfort and help manage energy use.

Most work with common furnaces, air conditioners and heat pumps, but some need a C-wire for power. Some ductless and variable-speed systems need the manufacturer’s own controls.

If your system doesn’t have a C-wire, an adapter or a new wire can often be added. We’ll check compatibility before installing.

A programmable thermostat follows a schedule you set. A smart thermostat adds Wi-Fi control, learning features, energy reports and remote access.

Smart thermostats are easier to adjust as your schedule changes. Programmable thermostats are a budget-friendly way to automate temperature changes.

On an interior wall away from direct sun, drafts, doors, windows, kitchens and heat sources, so it reads the true temperature of your home.

A thermostat in the wrong place can cause short cycling and uneven temperatures. Moving it is sometimes the best way to improve comfort.

Check the batteries, the breaker and the furnace power switch. Some systems cut power to the thermostat if a safety switch, like a condensate float switch, is triggered.

If the screen is still blank after checking these, the thermostat or wiring may need replacing. A technician can find the cause.

Auto runs the fan only when heating or cooling and uses less electricity. On runs it constantly for better air circulation and filtration.

Some smart thermostats offer a circulate setting that runs the fan part of each hour, a good balance between Auto and On.

With a furnace, yes. Lowering the temperature a few degrees while you sleep or are away reduces heating costs. With a heat pump, smaller setbacks work best.

With a gas furnace in a GTA home, lowering the temperature a few degrees overnight can cut Enbridge gas use over a long winter. With a heat pump, smaller setbacks work best, and some homeowners schedule heating around Ontario’s lower overnight electricity rates.

Yes. Your thermostat needs to support heat pumps and any backup heat, so the system switches between them correctly.

A heat pump thermostat manages auxiliary heat so it only runs when needed. The wrong thermostat can lead to higher bills.

Zoning divides your home into areas with their own thermostats and dampers or units, so you can heat or cool rooms differently.

Zoning is helpful in larger or multi-storey homes where different areas need different temperatures. It can be done with dampers in ducted systems or with ductless units.

Some homeowners do, but compatibility and wiring can be tricky, especially with heat pumps and multi-stage systems. A professional install makes sure everything works correctly.

Incorrect wiring can damage your system or prevent it from running properly. A professional install ensures everything works as it should.

Geofencing uses your phone’s location to adjust the temperature when you leave and return home, saving energy without you having to remember.

Geofencing works best when everyone in the household uses the app, so the system knows when the home is truly empty.

On heat pump systems, emergency heat runs only the backup heat source. It’s meant for when the heat pump isn’t working, not for everyday use.

Using emergency heat regularly can raise your energy bills, since backup heat is less efficient. Call us if you find you need it often.

Check the furnace power switch, breaker, filter and any error lights on the furnace. If those look fine, call for service.

Also make sure the thermostat is set to Heat and the temperature is set above the current room temperature.

Yes, with a Wi-Fi smart thermostat or a ductless system with a Wi-Fi adapter.

Phone control lets you adjust your home’s temperature from anywhere, and many systems send alerts if something goes wrong.

Regular maintenance keeps your system efficient and safe, catches small problems before they become breakdowns, and helps your equipment last longer.

Many breakdowns start as small issues, like a dirty part or a loose connection, that are easy to fix during maintenance. Regular service also helps protect your manufacturer warranty.

Book heating service in the fall and cooling service in the spring. Heat pumps benefit from a yearly visit, since they run all year.

In the GTA, book heating service in September or October and cooling service in April or May. Booking before the first cold night or heat wave means more flexible scheduling and time to fix any issues.

Our protection plans bundle regular maintenance with added benefits for your home comfort systems. Visit our Protection Plans page for current coverage details.

A protection plan makes it easy to stay on top of maintenance, without having to remember to book each year.

It can. Many manufacturers require proof of regular professional maintenance to honour warranty claims, so keep your service records.

Keep your maintenance records and receipts, along with your installation paperwork. They make warranty claims much easier.

Change or clean filters, keep vents open and clear, keep the outdoor unit free of snow and debris, and check that the condensate drain flows freely.

Leave gas, electrical and refrigerant work to licensed technicians. Simple homeowner care between visits helps your system run smoothly.

Most maintenance visits take about an hour per system, depending on its condition.

Our technicians will explain anything they find and give you options before doing any extra work.

Yes. If your heating or cooling stops working, call us and we’ll get a technician to you as quickly as we can.

If you smell gas, leave your home first and call the Enbridge Gas emergency line at 1-866-763-5427 from outside. For no-heat or no-cooling calls, let us know what’s happening and any error codes you see, so our technician comes prepared.

Yes. We offer free in-home consultations and quotes for new heating, cooling and water heating systems.

During your consultation, we’ll look at your home, talk about your goals and give you clear options and pricing.

Check the thermostat settings and batteries, the breaker, the furnace power switch and the filter. These simple checks solve many common problems.

If these checks don’t solve the problem, call us and we’ll get a technician out to help.

Yes. An adult should be home to give our technician access and to go over any findings and recommendations.

Make sure there’s a clear path to your equipment, and secure any pets before the technician arrives.

Spring Home has been installing and servicing heating and cooling systems across the GTA since 2001.

That’s more than two decades of experience installing and servicing heating, cooling and water heating systems in GTA homes.

Yes. We provide commercial and industrial HVAC installation, maintenance and repair.

Call us to talk about your building’s heating, cooling and maintenance needs, and we’ll recommend the right service.

Canada’s National Heat Pump Rebate is the main program for homeowners. It helps you switch to an eligible cold-climate heat pump that can heat your whole home.

Rebate programs can change, so it’s important to check the current rules before you buy. We’ll help you understand what applies to your home.

Households at or below the median after-tax income for their province and household size can receive up to $10,000. Households above it receive $2,000.

Your household income is based on your tax return, and the Canada Revenue Agency confirms it when you apply. Our rebate page includes an estimator to help you see where you may fall.

You must own the home and live in Canada. The heat pump must be on the eligible product list, be able to heat your whole home, and be purchased from and installed by an HVAC contractor.

There’s a limit of one rebate per household, and the address can’t have received federal heat pump funding before. Rental properties can qualify, since it doesn’t have to be your primary residence.

Eligible installations on or after November 1, 2026 may qualify, and the online portal is expected to open in early 2027. Keep your receipts and apply within six months.

Funding isn’t guaranteed until your application is approved, and program details may change. Keep all receipts and installation paperwork.

No. The National Heat Pump Rebate doesn’t require an energy audit before or after installation.

That makes the process simpler than many past programs. You’ll still need your invoice and equipment details to apply.

Toronto homeowners can use the National Heat Pump Rebate. Visit our Toronto Heat Pump Rebates page for details.

The same rules apply in Toronto as across Canada: the heat pump must be on the eligible product list, heat your whole home and be installed by an HVAC contractor. Our Toronto Heat Pump Rebates page explains how it works for GTA homeowners.

Commercial customers may qualify for incentives on hybrid rooftop units. Visit our Hybrid Rooftop Unit Rebate page or call us to find out more.

Rules and amounts vary by program. Our commercial team can help you understand what may apply to your building.

Yes. We offer flexible financing options on heating, cooling and water heating systems. Visit our HVAC Financing page for details.

Financing lets you spread the cost of a new system into manageable monthly payments, so you don’t have to delay an important upgrade.

Yes. Financing helps spread out the cost of your system, and the rebate is paid to you after you apply.

Some homeowners use their rebate to pay down their financing once it arrives. We’ll explain how it works.

Financing is typically subject to credit approval. Our team will walk you through the application.

Approval and terms depend on the financing provider. We’ll help you understand your options before you apply.

Buying outright usually costs least over time, financing spreads payments out while you own the system, and renting bundles service into a monthly fee. We’ll help you compare.

The right choice depends on your budget and how long you plan to stay in your home. We’ll lay out the options clearly.

Environment and Climate Change Canada doesn’t send door-to-door salespeople or make marketing calls about heating and cooling equipment. Contact HVAC companies yourself.

Report any suspicious calls or visits about rebates to Environment and Climate Change Canada. When in doubt, call us directly.

The homeowner applies, but we make sure your invoice includes the details the program asks for, like the make, model and AHRI number.

We’ll also confirm your system’s eligibility before installation, so you can apply with confidence.

Most current incentives focus on heat pumps. Check our Promotions page or call us for any current offers.

We sometimes run seasonal promotions on new equipment. Check our Promotions page or ask our team when you request a quote.

HVAC stands for heating, ventilation and air conditioning. It covers the systems that heat, cool and move air through your home.

HVAC systems also include related equipment like thermostats, humidifiers, air purifiers and ventilation systems.

A load calculation measures how much heating and cooling your home actually needs, based on insulation, windows, air leakage, orientation and layout. It’s the right way to size equipment.

Sizing by square footage alone often leads to systems that are too big or too small. A load calculation leads to better comfort, efficiency and equipment life.

An AHRI number identifies a certified, matched set of heating and cooling equipment. Rebate programs often use it to confirm eligibility.

Using the AHRI number ensures the outdoor and indoor equipment are a certified match, which affects efficiency and rebate eligibility.

A BTU (British Thermal Unit) is a measure of heat. Furnaces, heat pumps and air conditioners are rated by how many BTUs per hour they deliver.

Knowing the BTU rating helps compare systems, but the right size for your home still comes from a load calculation.

One ton of cooling equals 12,000 BTUs per hour. Most homes use systems between about 1.5 and 5 tons.

Bigger isn’t always better. The right tonnage depends on your home’s cooling and heating needs.

Keep up with maintenance, change filters, use a programmable or smart thermostat, seal air leaks, add insulation and consider a high-efficiency system.

Small changes add up. Ask us about a system check if your energy bills seem higher than they should be.

A lot. Better insulation and air sealing reduce how much heating and cooling your home needs, which can allow a smaller, more efficient system.

Improving your home’s envelope before replacing your system can also lead to better comfort and savings.

Heat rises, so upper floors are often warmer. Duct balancing, zoning, a variable-speed system or a ductless unit for problem areas can help.

Simple steps like keeping vents open and changing filters help. For bigger differences, our team can recommend the right solution.

Many installations, including most gas appliance replacements, require a permit and inspection. We take care of permits where they’re required.

In Toronto and many GTA municipalities, new HVAC installations and many replacements need a building permit, and gas work must be done by a TSSA-licensed gas technician. We take care of permits and inspections where they’re required.

Look for licensed, insured technicians, industry memberships like HRAI, strong reviews, a proper load calculation and a clear written quote.

In Ontario, make sure anyone working on gas appliances holds a TSSA gas technician licence. Ask for a load calculation, a clear written quote and references, and choose a contractor without pressure tactics.

A good quote lists the equipment make and model, efficiency ratings, warranty details, what’s included in installation, permits and the total price.

Comparing quotes side by side is easier when they include the same details. Don’t hesitate to ask questions.

Our team protects your floors, removes the old equipment, installs and tests the new system, cleans up and shows you how to use it.

We’ll explain how the system works, how to change filters and what maintenance it needs.

Spring and fall are ideal because you’re not relying on heating or cooling as much. But don’t wait for a breakdown if your system is old and unreliable.

In the GTA, spring and fall are ideal, between the heating and cooling seasons. Planning ahead also gives you time to review rebates and financing, instead of making a rushed decision during a January breakdown.

Sometimes. Heat pumps, multi-stage and variable-speed systems often need a compatible thermostat to work at their best.

We’ll recommend the right thermostat for your new system and set it up for you.

If your furnace and air conditioner are both older, replacing them together gives you a matched, efficient system and a single installation.

Replacing both at once can also reduce overall installation costs compared to doing them separately.

Clear a path to your furnace, water heater and outdoor unit, secure pets, and note any symptoms or error codes you’ve noticed.

It also helps to have your equipment’s model numbers handy if you can find them.
