How a Heat Pump Cools Your Home

In Charlotte, heat pumps can be a popular option for heating and cooling your house.

They appear almost like an air conditioner. In fact, they run in the same way during warm weather. Due to a reversing valve, they can move humidity in the opposite direction as well as add comfort to your residence in the winter.

Not sure if you have a heat pump or an air conditioner? All you need to do is track down the model number on the outdoor unit and look it up online. If you find you use a heat pump, or you’re thinking over purchasing one, learn more about how this HVAC system keeps residences comfy.

How Heat Pumps Run

Heat pumps have a refrigeration system like an air conditioner. Most can work 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 sent through these coils to move warmth. The outdoor unit also has a compressor and is enclosed by metal fins that act as a heat sink to help move heat properly.

Summertime Cooling

In cooling mode, the refrigerant is in the evaporator coil. Air from within the house blows over the coil, and the refrigerant extracts heat. Water 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.

Meanwhile, the refrigerant flows a compressor on its way to the outdoor coil. This compresses the refrigerant, causing it to get hotter. As it goes 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 greatly, prepping it to start the process all over again.

When your heat pump is put in and maintained properly, you’ll get efficient cooling on par with a high-performance air conditioner.

Wintertime Heating

When your heat pump is heating, the heat exchange cycle takes place the other way around. By flowing in the opposite direction, refrigerant pulls heat from the outdoor air and vents it into your residence to warm the inside.

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

Heat pumps run longer than furnaces as the air doesn’t turn as warm. This helps sustain a more stable indoor temperature. Also, because heat pumps move heat rather than generating it from a fuel source, they can perform well above 100% efficiency. You can anticipate 30–40% savings on your heating costs by installing a heat pump.
