How a Heat Pump Cools Your Home

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

They appear almost like an air conditioner. In actuality, they work in a nearly identical way during the summer. Because of a reversing valve, they can move heat 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? Just track down the model number on the outdoor unit and look it up online. If you discover you use a heat pump, or you’re considering getting one, discover how this HVAC equipment keeps homes cozy.

How Heat Pumps Work

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

Summertime Cooling

When your heat pump is cooling, the refrigerant starts in the evaporator coil. Air from indoors is distributed over the coil, and the refrigerant extracts heat. Wetness in the air also condenses on the coil, dropping into the condensate pan below and drains away. The ensuing cool air circulates through the ductwork and back into your home.

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 outside fan and metal fins help to emit heat to the exterior. The refrigerant heads back indoors, moving through an expansion valve that lowers its temperature it greatly, readying it to start the process from the start.

When your heat pump is put in and maintained properly, you’ll enjoy efficient cooling equivalent to a high-performance air conditioner.

Wintertime Heating

In heating mode, the heat exchange process takes place the other way around. By moving in the opposing direction, refrigerant removes heat from the outdoor air and adds it into your house to warm rooms.

Heat pumps working in heating mode are most effective when the temperature is warmer than freezing outside. If it becomes too cold, a backup electric resistance heater turns on to keep your house comfortable, but your heating expenses increase as a result.

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