THE BASICS
What Is a Heat Pump?
A heat pump heats and cools your home by transferring heat rather than generating it directly, making it far more energy-efficient than standard electric heating. They range from a single indoor unit for one room through to fully ducted systems covering an entire home. The right type depends on how much of your home you want covered — compare your options below.
