Product Brochure

When properly matched and installed, your DX3SE Air Conditioner offers up to 14.5 SEER2 energy-efficient performance. The higher the SEER2, the greater the efficiency — and the lower the operating cost compared to lower SEER2 units. In many applications, the efficiency of your DX3SE can be enhanced by using it in conjunction with a Daikin brand gas furnace. This unit features a powder-paint finish over heavy-gauge galvanized steel that provides premium durability and excellent UV protection. Supports the 2023 DOE Energy Conservation Standards.
