How a Heat Pump Cools Your House

In Memphis, heat pumps can be a popular solution for heating and cooling your home.

They seem about the same as an air conditioner. In fact, they run in a similar fashion during hot weather. Since they have a reversing valve, they can transfer humidity 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? Just find the model number on the outdoor unit and run it online. If it turns out you use a heat pump, or you’re thinking about purchasing one, find out how this HVAC equipment keeps houses comfy.

How Heat Pumps Run

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

Summertime Cooling

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

Meanwhile, the refrigerant moves a compressor on its way to the outdoor coil. This compresses the refrigerant, causing it to heat up even more. As it goes through the condensing coil, the outdoor fan and metal fins help to emit heat to the outdoors. The refrigerant moves back into your house, passing through an expansion valve that cools it considerably, readying it to go through the process from the beginning.

When your heat pump is replaced and maintained properly, you’ll enjoy efficient cooling as good as an energy-saving air conditioner.

Wintertime Heating

When your heat pump is heating, the heat exchange procedure happens in reverse. By traveling in a different direction, refrigerant extracts heat from the outdoor air and adds it into your residence to warm the interior.

Heat pumps working in heating mode are most useful when the temperature remains above freezing outside. If it becomes too cold, a backup electric resistance heater starts to keep your house comfortable, but your heating expenses go up as a result.

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