How a Heat Pump Cools Your Home

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

They look about the same as an air conditioner. In fact, they operate in the same way during high temperatures. Since they have a reversing valve, they can shift heat in the opposite direction as well as add warmth to your home in the winter.

Not sure if you rely on a heat pump or an air conditioner? All you have to do is find the model number on the outdoor unit and run it online. If it turns out you have a heat pump, or you’re thinking over installing one, find out how this HVAC equipment keeps houses comfortable.

How Heat Pumps Run

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

Summertime Cooling

When your heat pump is cooling, the refrigerant is in the evaporator coil. Air from within the house moves over the coil, and the refrigerant sucks out warmth. Water in the air also condenses on the coil, dropping into the condensate pan below and moves away. The ensuing cool air flows through the ductwork and back into your residence.

During this time, the refrigerant moves a compressor on its way to the outdoor coil. This constricts the refrigerant, causing it to warm up. As it moves through the condensing coil, the outside fan and metal fins help to exhaust heat to the outside. The refrigerant heads back into your house, moving through an expansion valve that chills it considerably, readying it to go through the process all over again.

When your heat pump is installed and maintained correctly, you’ll get efficient cooling similar to an energy-saving air conditioner.

Wintertime Heating

In heating mode, the heat exchange cycle takes place the other way around. By flowing in the opposite direction, refrigerant extracts heat from the outdoor air and disperses it into your residence to warm the interior.

Heat pumps working in heating mode are most effective when the temperature is above freezing outside. If it gets too chilly, a backup electric resistance heater kicks on to keep your house comfortable, but your heating expenses go up as a result.

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