How a Heat Pump Cools Your House

In the U.S., heat pumps can be a popular solution for heating and cooling your house. 

They look about the same as an air conditioner. In reality, they operate in a similar fashion during high temperatures. Due to a reversing valve, they can transfer humidity in the opposite direction as well as add comfort to your residence when it’s cold. 

Not sure if you rely on a heat pump or an air conditioner? Just track down the model number on the outdoor unit and run it online. If it turns out you use a heat pump, or you’re considering buying one, discover how this HVAC equipment keeps houses cozy. 

How Heat Pumps Work 

Heat pumps have a refrigeration system similar to an air conditioner. Most can run like 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 sent through these coils to shift humidity. The outdoor unit also contains a compressor and is enclosed by metal fins that act as a heat sink to help shift heat efficiently. 

Summertime Cooling 

In cooling mode, the refrigerant is in the evaporator coil. Air from inside the house blows over the coil, and the refrigerant sucks out warmth. Water in the air also condenses on the coil, falling into the condensate pan below and flows away. The resulting cool air circulates through the ductwork and back into your residence. 

During this time, the refrigerant moves a compressor on its way to the outdoor coil. This compresses the refrigerant, leading 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, moving through an expansion valve that lowers its temperature it considerably, prepping it to begin the process all over again. 

When your heat pump is replaced and maintained properly, you’ll have efficient cooling similar to a high-performance air conditioner. 

Wintertime Heating 

When your heat pump is set to heat, the heat exchange cycle happens in reverse. By traveling in a different direction, refrigerant extracts heat from the outdoor air and disperses it into your residence to warm rooms. 

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

Heat pumps operate longer than furnaces because the air doesn’t become as hot. This helps maintain a more balanced indoor temperature. On top of that, because heat pumps move hot air rather than making it from a fuel source, they can perform well above 100% efficiency. You should receive 30–40% savings on your heating bills by getting a heat pump.
