A heat pump can serve as both a heating and air conditioning system. In the winter, heat is absorbed from the outdoor air and released to the indoor air. Since the ground and air outside always contain some heat, a heat pump can supply heat to a house even on cold winter days. In fact, at -18 C, the air contains about 85% of the heat contained therein to 21 C.

In summer, the cycle is reversed to remove the heat and humidity of the house and provide cool air.
