Heat pumps are a highly powerful and energy efficient alternative to traditional central AC systems. Heat pumps help keep you comfortable year-round because they have both heating and cooling functions. In the summer, they pull heat from your home and expel it outside. Throughout the winter, heat pumps switch functions and drawing warm air from outdoors back into your house.
SEER Rating: Seasonal Energy Efficiency Ratio, or the ratio of the cooling output of an AC system during a typical cooling season, divided by the energy it uses in Watt-Hours. Like miles-per-gallon in your car, the the higher the SEER Rating the more cooling comfort you get per dollar spent on energy.
