What is a heat pump?

A heat pump is a single appliance that can provide both your heating and cooling. During the summer, the heat pump works like a conventional air conditioner, cooling the home. In winter, the heat pump reverses its flow and heats your home by extracting heat from the outside air and pumping it to your house. Usually a heat pump is an add-on system that improves the efficiency of your conventional gas or electric furnace. When the weather is very cold, the heat pump shuts off and your furnace takes over.

One feature in many models is a variable speed compressor that alters its power usage based on the need for heating or cooling. When needs are minimal, the compressor runs at slower speeds. Variable speed units provide better humidity control during the cooling season and are much quieter for year-round operation.
