  • Conventional ducted systems
  • Space pak systems
  • Ductless systems

Hybrid Systems

Hybrid Heat systems deliver exceptional performance by using a heating source that provides its most energy-efficient comfort during moderate heating conditions. As the temperature drops outside, the system automatically switches to your second heating source when that becomes the most economical way to keep your family comfortable

Heating

Hybrid Heating systems include a gas furnace with a heat pump to provide soothing, superior comfort during both heat pump and furnace operation. This powerful combination can deliver heated air temperatures that are warmer than most traditional heat pumps so air from your vents feels warmer to the touch.

Cooling

Because a Hybrid Heat system also provides cool, indoor comfort when it’s hot outside, this system becomes your total, year-round indoor comfort solution. With the recent increase in the SEER rating (SEER = Seasonal Energy Efficiency Ratio) of air conditioners and heat pumps, a Hybrid Heat system could also save you money during the cooling season.
