Heat Pumps are air conditioners that run in reverse. They extract heat from outside and pump it inside. Heat pumps can be installed with an electric furnace on the inside or combined with a gas furnace. Either of these options create a dual fuel hybrid heating and cooling system.

In more moderate temperatures, a dual fuel hybrid system uses the electric heat pump to heat your home. When temperatures drop below freezing, it automatically switches over to gas. Since electric companies tend to charge less for electricity during the winter months, using an electric furnace can save you money.

A heat pump makes an ideal heating/cooling system for a basement remodel or a room addition. It is more efficient, has a lower upfront cost, and is less complicated to install compared to a traditional gas-fuel system.
