How Does a Heat Pump Work?

In mild climates like Mission Viejo, CA, heat pump technology makes an attractive alternative to traditional gas furnace systems. Heat pumps combine the function of a heater and an air conditioner into a single unit, allowing you to both heat and cool the house with one system. According to the U.S. Department of Energy, they can save up to 40% on your monthly bills. They function best in mild climates where temperatures don’t drop below 40 degrees very often, making them perfect for Southern California towns like Mission Viejo.

How does a heat pump work? Read on for the answers.

Heat pumps are based on the same technology as traditional air conditioners, which involves a closed loop system that circulates refrigerant gas. In the summer, the gas enters a compressor on the outside part of the unit, which subjects it to a huge amount of pressure and heat. The pressurized gas then moves to a series of condenser coils, which bleed off the heat into the outside air and reduce the gas to a liquid state. Still under pressure, the liquid moves to the inside part of the unit and passes through an expansion valve into a series of evaporator coils. As the liquid evaporates, it pulls heat from the air above the coils, making it very cold. A blower fan then blows the cold air into your home, keeping the air cool and comfortable when temperatures rise. The gas then returns to the compressor to start the cycle all over again.

That’s the summertime. In the winter, you essentially reverse the process. The evaporator array becomes the condenser and the condenser array becomes the evaporator: releasing cold air outside and blowing hot air into your home.

Heat pumps usually cost a little more to install than gas furnaces, which can be offset by their increased savings and efficiency.  If you need Mission Viejo heating service, there’s a reliable company nearby to help.
