What It Does

Simply put, a heat pump can both heat and cool your home. In the summer time, it acts just like an air conditioner and moves heat from inside your home to the outdoors and cools the air to the temperature setting. It does exactly the opposite in the winter, capturing heat from the outdoors and moving it into your home and then warming the air as needed.

What It Looks Like

A heat pump looks just like a central air conditioner and most of the components are the same. An indoor air handler is attached to ductwork. The outdoor unit runs very quietly and inconspicuously. Running between the outdoor unit and the air handler is a pair of copper pipes called a ‘line set’. These are the pipes through which the refrigerant travels between the outdoor unit and the air handler. Air source heat pumps can maintain operating efficiencies at outdoor air temperatures as low as -15°F.
