How Heat Pumps Work

Amana heat pump

A heat pump works like an air conditioner to transfer heat away from your New Deal, Texas, home in summer. In winter, it reverses directions and absorbs heat from the air outside your home instead. That way, a heat pump keeps you and your family comfortable all year. It may be more expensive than a conventional air conditioner, but it’s worth the investment since you can save money on your utility bills. Also, you won’t need to pay for a separate furnace. Here’s some useful information about how heat pumps work in summer and winter.

How Heat Pumps Work in Summer

A motorized fan pulls warm air from the inside of your home into your ductwork through one or more return vents. Then, the warm air indoor air travels to the indoor air handler. It passes over the interior evaporator coil while a special liquid called refrigerant travels through the coil. The refrigerant absorbs heat from your indoor air, and the cooled and dehumidified air goes back to your ductwork. The motorized fan pushes it through your air registers and into your home. When your air temperature rises, the cycle starts again, pulling warm air into your ductwork.

How They Work in Winter

To heat your home, your heat pump reverses the direction that the refrigerant flows, turning the coil in your outdoor unit into the evaporator coil. Your outdoor unit absorbs heat from the outside air and then releases it through the coil in your indoor air handler. This heats your indoor air as it moves through your ductwork instead of cooling it. The coil that releases heat is a condenser coil. It’s indoors in winter and outdoors in summer.

Great experience! Called 3 companies before BTAC and they all told me it would be a couple of days. I called BTAC and they were here within the hour. Jeremy came out to look at our AC unit and was extremely professional. I admitted I knew nothing about HVAC units and he made sure to let me know step by step what was going on and what to look for in the future. Wonderful experience. They will always be my first call now.

Jeff, the plumber, and his helper, John, were fantastic about diagnosing and treating our plumbing issue. They quickly fixed our problem! Jeremy, the HVAC expert, was also quite good at formulating a rule-out diagnosis and was very cordial.
