How a Heat Pump Cools Your Home

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

They seem almost like an air conditioner. In fact, they run in a similar fashion during the summer. Because of a reversing valve, they can move warmth in the opposite direction as well as add comfort to your home when it's cold.

Not sure if you rely on a heat pump or an air conditioner? Simply locate the model number on the outdoor unit and run it online. If it turns out you own a heat pump, or you’re considering installing one, discover how this HVAC equipment keeps residences comfortable.

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 have an indoor evaporator coil and an outdoor condensing coil. Refrigerant is moved through these coils to transfer heat. The outdoor unit also uses 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 set to cooling, the refrigerant starts in the evaporator coil. Air from within the house is distributed over the coil, and the refrigerant extracts warmth. Moisture in the air also condenses on the coil, dropping into the condensate pan below and moves 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 discharge heat to the outside. The refrigerant travels back into your house, 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 as good as an energy-saving air conditioner.

Wintertime Heating

In heating mode, the heat exchange procedure takes place the opposite way. By moving in a different direction, refrigerant pulls heat from the outdoor air and adds it into your residence to warm the inside.

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

Heat pumps work longer than furnaces as the air doesn’t get as warm. This helps sustain a more even indoor temperature. Additionally, 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.
