How a Heat Pump Cools Your Home

In the U.S., heat pumps can be a popular choice to heat and cool your house. 

They appear very similar to an air conditioner. In reality, they run in the same way during hot weather. Because of a reversing valve, they can transfer warmth in the opposite direction as well as add warmth to your home when it’s cold. 

Not sure if you have a heat pump or an air conditioner? All you need to do is locate the model number on the outdoor unit and check it online. If it turns out you use a heat pump, or you’re considering installing one, discover how this HVAC unit keeps residences cozy. 

How Heat Pumps Work 

Heat pumps have a refrigeration system similar to an air conditioner. Most can run similar to a ductless mini-split, because they can heat and cool. Heat pumps rely on an indoor evaporator coil and an outdoor condensing coil. Refrigerant is pumped through these coils to transfer humidity. The outdoor unit also contains a compressor and is enclosed by metal fins that work as a heat sink to help move humidity efficiently. 

Summertime Cooling 

When your heat pump is set to cooling, the refrigerant begins in the evaporator coil. Air from inside the house is distributed over the coil, and the refrigerant sucks out heat. Moisture in the air also condenses on the coil, dropping into the condensate pan below and moves away. The ensuing cool air moves through the ductwork and back into your residence. 

At the same time, the refrigerant moves a compressor on its way to the outdoor coil. This concentrates 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 moves back inside, traveling through an expansion valve that lowers its temperature it considerably, readying it to go through the process from the beginning. 

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

Wintertime Heating 

When your heat pump is set to heat, the heat exchange procedure occurs in reverse. By moving in the opposing direction, refrigerant extracts heat from the outdoor air and disperses it into your home to warm rooms. 

Heat pumps running in heating mode are most useful when the temperature is above freezing outside. If it turns too frigid, a backup electric resistance heater turns on to keep your residence comfy, but your heating expenses go up as a result. 

Heat pumps work longer than furnaces because the air doesn’t become as warm. This helps maintain a more balanced indoor temperature. Also, because heat pumps move warmth rather than generating it from a fuel source, they can operate well above 100% efficiency. You should expect 30–40% savings on your heating costs by getting a heat pump.
