EarthWise® Hybrid Dual Fuel Packaged Systems

A dual fuel packaged HVAC system gives you the best of both the heating and cooling worlds. Inside one sleek cabinet, this system houses a heat pump that cools your home and heats it in mild to cold temperatures, as well as a gas furnace that heats when the temperatures truly drop. A dual fuel system can help you save both energy and money on your home temperature control.

The SEER2 (Seasonal Energy Efficiency Ratio) rating on your dual fuel packaged system is an energy rating for the heat pump inside. The SEER2 rating is an indication of how well the heat pump in your packaged system can cool your home, and the higher the SEER2 the more efficient the system is at cooling. A good rule of thumb is to look for SEER2 ratings that exceed the minimums set by the Department of Energy, effective Jan. 1, 2023.

The HSPF2 (Heating Seasonal Performance Factor) rating on your dual fuel packaged system is the opposite of the SEER2 rating. While SEER2 measures how efficiently the heat pump in your system can cool, HSPF2 measures how efficiently the heat pump in your system can heat. In most cases, homeowners should look for a system that has an HSPF2 of 6.7 or higher, as is the minimum set by the Department of Energy for single-packaged heat pumps, effective Jan. 1, 2023.

The AFUE (Annual Fuel Utilization Efficiency) rating is the only energy rating for your dual fuel packaged system that refers to the gas furnace. The AFUE measures how efficiently the gas furnace in the system can heat your home, and the higher the rating the more efficient the furnace. Homeowners should look for an AFUE rating that is higher than 80% in most cases.
