How a Heat Pump Cools Your Home

In Columbia, heat pumps can be a popular choice to heat and cool your house.

They appear about the same as an air conditioner. In fact, they operate in a similar fashion during the summer. Since they have a reversing valve, they can move warmth in the opposite direction as well as add comfort to your home when temperatures drop.

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

How Heat Pumps Work

Heat pumps have a refrigeration system much like an air conditioner. Most can operate similar to a ductless mini-split, because they can heat and cool. Heat pumps have an indoor evaporator coil and an outdoor condensing coil. Refrigerant is moved through these coils to transfer heat. The outdoor unit also has a compressor and is surrounded by metal fins that function as a heat sink to help shift heat efficiently.

Summertime Cooling

When your heat pump is cooling, the refrigerant starts in the evaporator coil. Air from indoors is distributed over the coil, and the refrigerant extracts humidity. Moisture in the air also condenses on the coil, dropping into the condensate pan below and flows away. The resulting dehumidified air circulates through the ductwork and back into your residence.

At the same time, the refrigerant passes through a compressor on its way to the outdoor coil. This concentrates the refrigerant, causing it to heat up even more. As it flows through the condensing coil, the outside fan and metal fins help to emit heat to the outdoors. The refrigerant travels back indoors, passing through an expansion valve that cools it significantly, prepping it to go through the process from the beginning.

When your heat pump is installed and maintained correctly, you’ll have efficient cooling similar to an energy-efficient air conditioner.

Wintertime Heating

In heating mode, the heat exchange process happens the other way around. By moving in a different direction, refrigerant removes heat from the outdoor air and vents it into your residence to warm rooms.

Heat pumps operating in heating mode are most effective when the temperature remains above freezing outside. If it gets too frigid, a backup electric resistance heater kicks on to keep your home cozy, but your heating bills go up as a result.

Heat pumps work longer than furnaces since the air doesn’t get as heated. This helps sustain a more balanced indoor temperature. On top of that, because heat pumps transfer hot air rather than making it from a fuel source, they can perform well above 100% efficiency. You can anticipate 30–40% savings on your heating bills by using a heat pump.
