How a Heat Pump Cools Your Home

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

They look about the same as an air conditioner. In fact, they run in a similar fashion during high temperatures. Due to a reversing valve, they can move warmth in the opposite direction as well as add warmth to your residence in the winter.

Not sure if you have a heat pump or an air conditioner? All you need to do is locate the model number on the outdoor unit and look it up online. If it turns out you own a heat pump, or you’re thinking over purchasing one, find out how this HVAC system keeps residences comfortable.

How Heat Pumps Operate

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

Summertime Cooling

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

At the same time, the refrigerant passes through a compressor on its way to the outdoor coil. This compresses the refrigerant, forcing it to get hotter. As it flows through the condensing coil, the exterior fan and metal fins help to discharge heat to the exterior. The refrigerant heads back into your house, moving through an expansion valve that chills it greatly, prepping it to begin the process all over again.

When your heat pump is replaced and maintained correctly, you’ll have efficient cooling equivalent to an energy-efficient air conditioner.

Wintertime Heating

When your heat pump is set to heat, the heat exchange cycle takes place the other way around. By flowing in the opposing direction, refrigerant extracts heat from the outdoor air and vents it into your residence to warm the inside.

Heat pumps operating in heating mode are most effective when the temperature is above freezing outside. If it becomes too chilly, a backup electric resistance heater starts to keep your house cozy, but your heating costs go up as a result.

Heat pumps run longer than furnaces because the air doesn’t become as warm. This helps keep a more even indoor temperature. Also, because heat pumps transfer heat rather than generating it from a fuel source, they can work well above 100% efficiency. You should receive 30–40% savings on your heating expenses by using a heat pump.
