How a Heat Pump Cools Your House

In Charleston, heat pumps can be a popular option for heating and cooling your home.

They appear about the same as an air conditioner. In reality, they work in a nearly identical way during warm weather. Since they have a reversing valve, they can shift humidity in the opposite direction as well as add comfort to your residence when it's cold.

Not sure if you have a heat pump or an air conditioner? Just track down the model number on the outdoor unit and check it online. If it turns out you use a heat pump, or you’re considering installing one, find out how this HVAC unit keeps houses comfortable.

How Heat Pumps Operate

Heat pumps depend on a refrigeration system much like an air conditioner. Most can work akin to a ductless mini-split, since they can heat and cool. Heat pumps use an indoor evaporator coil and an outdoor condensing coil. Refrigerant is sent through these coils to move warmth. The outdoor unit also contains a compressor and is encircled by metal fins that function as a heat sink to help shift warmth effectively.

Summertime Cooling

When your heat pump is cooling, the refrigerant begins in the evaporator coil. Air from inside the house is distributed over the coil, and the refrigerant extracts warmth. Water in the air also condenses on the coil, dripping into the condensate pan below and moves away. The resulting cold air flows through the ductwork and back into your house.

During this time, the refrigerant flows a compressor on its way to the outdoor coil. This concentrates the refrigerant, leading it to warm up. As it goes through the condensing coil, the outdoor fan and metal fins help to discharge heat to the outside. The refrigerant moves back inside, traveling through an expansion valve that cools it greatly, readying it to start the process from the start.

When your heat pump is replaced and maintained correctly, you’ll receive efficient cooling equivalent to a high-performance air conditioner.

Wintertime Heating

When your heat pump is heating, the heat exchange process takes place the opposite way. By flowing in a different direction, refrigerant extracts heat from the outdoor air and disperses it into your residence to warm the inside.

Heat pumps operating in heating mode are most useful when the temperature is above freezing outside. If it turns too cold, a backup electric resistance heater turns on to keep your home comfortable, but your heating costs increase as a result.

Heat pumps operate longer than furnaces as the air doesn’t become as heated. This helps sustain a more balanced indoor temperature. Additionally, because heat pumps shift hot air rather than creating it from a fuel source, they can operate well above 100% efficiency. You can anticipate 30–40% savings on your heating costs by using a heat pump.
