How a Heat Pump Cools Your Residence

In North America, heat pumps can be a popular choice to heat and cool your home.

They look about the same as an air conditioner. In fact, they run in the same way during hot weather. Because of a reversing valve, they can transfer warmth in the opposite direction as well as add comfort to your house in the winter.

Not sure if you rely on a heat pump or an air conditioner? All you need to do is locate 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 buying one, learn more about how this HVAC equipment keeps homes comfortable.

How Heat Pumps Work

Heat pumps have a refrigeration system much like an air conditioner. Most can run akin to a ductless mini-split, as they can heat and cool. Heat pumps have an indoor evaporator coil and an outdoor condensing coil. Refrigerant is sent through these coils to shift humidity. The outdoor unit also uses a compressor and is encircled by metal fins that work as a heat sink to help shift warmth properly.

Summertime Cooling

When your heat pump is set to cooling, the refrigerant is in the evaporator coil. Air from inside the house blows over the coil, and the refrigerant extracts warmth. Water in the air also condenses on the coil, falling into the condensate pan below and drains away. The ensuing cool air moves through the ductwork and back into your residence.

During this time, the refrigerant flows a compressor on its way to the outdoor coil. This compresses the refrigerant, forcing it to heat up even more. As it moves through the condensing coil, the outdoor fan and metal fins help to exhaust heat to the exterior. The refrigerant moves back inside, passing through an expansion valve that lowers its temperature it considerably, preparing it to begin the process all over again.

When your heat pump is put in and maintained appropriately, you’ll enjoy efficient cooling as good as a high-performance air conditioner.

Wintertime Heating

When your heat pump is set to heat, the heat exchange procedure occurs in reverse. By flowing in the opposing direction, refrigerant pulls heat from the outdoor air and vents it into your residence to warm the inside.

Heat pumps working in heating mode are most useful when the temperature is warmer than freezing outside. If it becomes too cold, a backup electric resistance heater starts to keep your residence cozy, but your heating bills increase as a result.

Heat pumps are on longer than furnaces because the air doesn’t become as heated. This helps maintain a more stable indoor temperature. Also, because heat pumps transfer hot air rather than making it from a fuel source, they can operate well above 100% efficiency. You should expect 30–40% savings on your heating costs by getting a heat pump.
