A properly installed heat pump is one of the most efficient ways you can provide comfort into your home. The unit operates very much like an air conditioner but has a reversing valve that allows heat to be captured outside and brought into your home when needed. This unit heats very well when operating in outdoor temperatures above 40 degrees Fahrenheit. During colder temps a secondary heat source often assists. A heat pump is often paired with an electric air handler but can be easily adapted to function with a gas furnace. This is often referred to as a dual fuel system.
