How a Heat Pump Cools Your Home

In the U.S., heat pumps can be a popular option for heating and cooling your residence. 

They seem very similar to an air conditioner. In actuality, they operate in a similar fashion during the summer. Because of a reversing valve, they can transfer warmth in the opposite direction as well as heat your house when it’s cold. 

Not sure if you use a heat pump or an air conditioner? Simply locate the model number on the outdoor unit and run it online. If you discover you own a heat pump, or you’re thinking about buying one, discover how this HVAC unit keeps homes comfy. 

How Heat Pumps Operate 

Heat pumps rely on a refrigeration system similar to an air conditioner. Most can run like a ductless mini-split, as they can heat and cool. Heat pumps depend on an indoor evaporator coil and an outdoor condensing coil. Refrigerant is sent through these coils to move humidity. The outdoor unit also has a compressor and is enclosed by metal fins that function as a heat sink to help move warmth properly. 

Summertime Cooling 

When your heat pump is set to cooling, the refrigerant is in the evaporator coil. Air from within the house blows over the coil, and the refrigerant extracts humidity. Water in the air also condenses on the coil, dropping into the condensate pan below and flows away. The ensuing cool air circulates through the ductwork and back into your residence. 

At the same time, the refrigerant flows a compressor on its way to the outdoor coil. This constricts the refrigerant, leading it to heat up even more. As it moves through the condensing coil, the outside fan and metal fins help to exhaust heat to the outdoors. The refrigerant heads back inside, passing through an expansion valve that cools it greatly, readying it to start the process from the start. 

When your heat pump is replaced and maintained properly, you’ll have efficient cooling comparable to an energy-efficient air conditioner. 

Wintertime Heating 

When your heat pump is heating, the heat exchange process takes place the opposite way. By moving in a different direction, refrigerant removes heat from the outdoor air and vents it into your house to warm rooms. 

Heat pumps running in heating mode are most efficient when the temperature remains above freezing outside. If it turns too chilly, a backup electric resistance heater kicks on to keep your home cozy, but your heating bills rise as a result. 

Heat pumps operate longer than furnaces as the air doesn’t get as hot. This helps maintain a more balanced indoor temperature. Also, because heat pumps move warmth rather than creating it from a fuel source, they can perform well above 100% efficiency. You can anticipate 30–40% savings on your heating bills by switching to a heat pump.
