Hybrid Rooftop Unit Rebates up to $8,000+ per Unit
Replacing a gas rooftop unit, or adding RTUs to a new building? A hybrid RTU pairs an air-source heat pump with natural gas backup heat. You get efficient electric heating most of the year and dependable gas heat on the coldest days. Spring Home sizes, installs and commissions your units so you qualify for the Enbridge Gas Hybrid RTU incentive.
- Packaged, single-zone hybrid RTUs
- Replaces an existing gas RTU, or new construction
- Incentive capped at 50% of eligible equipment cost
- Typically paid within 8 weeks of commissioning
What Is a Hybrid Rooftop Unit?
A hybrid RTU is a packaged rooftop unit with two heat sources: an air-source heat pump and a natural gas furnace. In mild weather the heat pump moves heat from outdoor air into your building, and in summer it provides cooling. When temperatures drop, the controls bring in the gas furnace so occupants stay comfortable.
To qualify, the unit's controls must allow a switchover temperature of 30°F (-1.1°C) or below, or let the heat pump and gas furnace run at the same time. Move the slider to see how a hybrid RTU chooses its heat source.
Outdoor Temperature
Shown with a 30°F switchover. The exact settings depend on how the unit and controls are configured for your building.





Hybrid RTU Rebates by Heating Capacity
The incentive is based on the unit's rated heating capacity at 47°F, counting only the heat pump (non-furnace) heating output.
The incentive can't exceed 50% of eligible equipment cost. Units of 201 kBtu/hr or more that don't meet the prescriptive criteria may qualify for custom incentives.
