What is an air-source heat pump?
Heat pumps transfer heat from outside to inside or vice a versa. This provides both heating and cooling. A heat pump works on a fundamental principle that heat does exist in extremely cold air down to negative 460 degrees. To cool a house an air conditioner gathers heat from inside and transfers it to the outdoors. In winter a heat pump gathers the heat in the air outside and delivers it to the home.

During most of the winter a heat pump cost less to heat your home than a fossil fuel furnace. In severe winter weather when a heat pump loses it efficiency due to extreme cold a back-up heat source is needed – either electric or gas.

A heat pump can be added to an existing furnace. A heat pump would replace your central air conditioning system and provide both heating and cooling in conjunction with either a new or your current furnace.
