How a Heat Pump Cools Your House

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

They seem very similar to an air conditioner. In actuality, they run in a similar fashion during the summer. Due to a reversing valve, they can move heat in the opposite direction as well as add comfort to your residence in the winter.

Not sure if you use a heat pump or an air conditioner? All you have to do is locate the model number on the outdoor unit and run it online. If you discover you have a heat pump, or you’re thinking about buying one, discover how this HVAC system keeps residences cozy.

How Heat Pumps Run

Heat pumps rely on a refrigeration system similar to an air conditioner. Most can run similar to a ductless mini-split, since they can heat and cool. Heat pumps have an indoor evaporator coil and an outdoor condensing coil. Refrigerant is moved through these coils to shift warmth. The outdoor unit also contains a compressor and is encircled by metal fins that act as a heat sink to help move heat effectively.

Summertime Cooling

In cooling mode, the refrigerant begins in the evaporator coil. Air from within the house moves over the coil, and the refrigerant extracts heat. Moisture in the air also condenses on the coil, dropping into the condensate pan below and moves away. The resulting cool air moves through the ductwork and back into your home.

Meanwhile, the refrigerant passes through a compressor on its way to the outdoor coil. This constricts the refrigerant, causing it to get hotter. As it flows through the condensing coil, the outdoor fan and metal fins help to emit heat to the outside. The refrigerant travels back inside, traveling through an expansion valve that cools it considerably, readying it to begin the process all over again.

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

Wintertime Heating

When your heat pump is set to heat, the heat exchange process takes place the opposite way. By flowing in a different direction, refrigerant removes heat from the outdoor air and vents it into your home to warm the interior.

Heat pumps working in heating mode are most efficient when the temperature is above freezing outside. If it becomes too frigid, a backup electric resistance heater turns on to keep your house comfortable, but your heating costs rise as a result.

Heat pumps operate longer than furnaces as the air doesn’t turn as warm. This helps sustain a more stable indoor temperature. Additionally, because heat pumps move 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 costs by switching to a heat pump.
