How a Heat Pump Works | Alabama Power

Installing an electric heat pump is the most economical way to keep your home comfortable year-round.


How does a heat pump work?

Heat pumps utilize electricity to move heat from a cool space to a warm space, making the cool space cooler and warm space warmer. Even in cold air, heat energy is present so when it’s cold outside, a heat pump takes the heat in the outside air and transfers it inside, warming your home. During warmer weather, it reverses direction, acting like an air conditioner, to remove heat from your home.

There are some important things to consider when choosing a heat pump:

  1. Size: Select the right size for your home. If a heat pump is undersized or oversized it will not heat or cool your home effectively.

  2. Fuel source: Electric heat pumps are an economical way to heat and cool your home.

  3. Energy efficiency: Maximize energy savings and help the environment when you select an ENERGY STAR® rated electric heat pump.

  4. Seasonal Energy Efficiency Ratio (SEER): Air-source and dual-fuel systems measure cooling efficiency by SEER. The federal minimum standard for new homes in the Southeast is 14 SEER.
