How a Heat Pump Cools Your Home

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 nearly identical way during the summer. Because of a reversing valve, they can transfer heat in the opposite direction as well as add comfort to your house in the winter. 

Not sure if you use a heat pump or an air conditioner? Just 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 buying one, discover how this HVAC system keeps homes comfortable. 

How Heat Pumps Work 

Heat pumps depend on a refrigeration system like an air conditioner. Most can operate similar to a ductless mini-split, because 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 move heat. The outdoor unit also uses a compressor and is surrounded by metal fins that act as a heat sink to help move warmth effectively. 

Summertime Cooling 

When your heat pump is cooling, the refrigerant starts in the evaporator coil. Air from inside the house blows over the coil, and the refrigerant extracts warmth. Water in the air also condenses on the coil, dripping into the condensate pan below and drains away. The ensuing cool air moves 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 constricts the refrigerant, causing it to heat up even more. As it flows through the condensing coil, the exterior fan and metal fins help to discharge heat to the outside. The refrigerant moves back inside, moving through an expansion valve that lowers its temperature it greatly, readying it to go through the process from the start. 

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

Wintertime Heating 

When your heat pump is heating, the heat exchange procedure happens in reverse. By traveling in a different direction, refrigerant removes heat from the outdoor air and vents it into your residence to warm the inside. 

Heat pumps running in heating mode are most effective when the temperature is above freezing outside. If it becomes too frigid, a backup electric resistance heater kicks on to keep your home comfy, but your heating costs increase as a result. 

Heat pumps are on longer than furnaces because the air doesn’t turn as hot. This helps maintain a more stable indoor temperature. Additionally, because heat pumps transfer warmth rather than making it from a fuel source, they can operate well above 100% efficiency. You should receive 30–40% savings on your heating expenses by switching to a heat pump.
