Using electricity as its energy source, heat pumps are used for either the heating or cooling of your home by transferring heat between two reservoirs.
In the warmer months, the heat pump acts like an air conditioner, removing heat from the air inside your home and transferring it outside.
During colder months, heat from outdoor air is extracted and transferred to the interior of your home. Believe it or not, even a 35° Fahrenheit day produces enough heat to warm a home using a heat pump. Below freezing temperatures, a backup source of heat may be required to augment the heat pump, typically a small set of electric heat strips installed in the air handler.
