How a Heat Pump Cools Your House

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 shift humidity in the opposite direction as well as add warmth to your residence in the winter.

Not sure if you use a heat pump or an air conditioner? All you need to do is track down the model number on the outdoor unit and check it online. If it turns out you own a heat pump, or you’re thinking about getting 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 operate akin to a ductless mini-split, as they can heat and cool. Heat pumps rely on an indoor evaporator coil and an outdoor condensing coil. Refrigerant is sent through these coils to move warmth. The outdoor unit also uses a compressor and is encircled by metal fins that work as a heat sink to help shift warmth efficiently.

Summertime Cooling

When your heat pump is set to cooling, the refrigerant is in the evaporator coil. Air from inside the house is set 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 house.

At the same time, the refrigerant flows a compressor on its way to the outdoor coil. This compresses the refrigerant, leading it to heat up even more. As it goes 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 chills it considerably, preparing it to begin the process all over again.

When your heat pump is put in and maintained appropriately, you’ll receive efficient cooling similar to 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 a different direction, refrigerant removes heat from the outdoor air and vents it into your house to warm the inside.

Heat pumps working in heating mode are most useful when the temperature is warmer than freezing outside. If it turns too cold, a backup electric resistance heater turns on to keep your residence comfy, but your heating bills go up 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 work well above 100% efficiency. You should expect 30–40% savings on your heating expenses by switching to a heat pump.
