In the summer, a heat pump removes heat from inside your home and
replaces it with cool air. Simply speaking, it works just like a
conventional, high-efficiency air conditioner.
In the winter, the system works in reverse. It removes available
heat from the air outside your home (yes, there is heat in cold
outdoor air) and moves it indoors, providing an even, comfortable
temperature level throughout your home. There are seldom any warm or
cold spots such as those that exist when a gas furnace alone is
used.
When outdoor temperatures drop
below 20 degrees or so, a back-up heating system automatically provides supplemental heat.
