How a Heat Pump Cools Your Residence

In the U.S., heat pumps can be a popular option for heating and cooling your residence. 

They seem about the same as an air conditioner. In reality, they run in the same way during warm weather. Due to a reversing valve, they can move humidity in the opposite direction as well as add comfort to your house when it’s cold. 

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 look it up online. If you discover you use a heat pump, or you’re considering buying one, learn more about how this HVAC unit keeps homes cozy. 

How Heat Pumps Operate 

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

Summertime Cooling 

When your heat pump is set to cooling, the refrigerant begins in the evaporator coil. Air from indoors is distributed over the coil, and the refrigerant removes humidity. Moisture in the air also condenses on the coil, falling into the condensate pan below and drains away. The resulting cold air circulates through the ductwork and back into your house. 

Meanwhile, the refrigerant passes through a compressor on its way to the outdoor coil. This concentrates the refrigerant, forcing it to heat up even more. As it flows through the condensing coil, the outdoor fan and metal fins help to discharge heat to the exterior. The refrigerant travels back into your house, moving through an expansion valve that lowers its temperature it considerably, prepping it to start the process from the beginning. 

When your heat pump is installed and maintained appropriately, you’ll get efficient cooling comparable to a high-performance air conditioner. 

Wintertime Heating 

When your heat pump is set to heat, the heat exchange process occurs the opposite way. By moving in the opposite direction, refrigerant extracts heat from the outdoor air and adds it into your residence to warm the inside. 

Heat pumps working 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 residence comfy, 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 stable indoor temperature. Also, because heat pumps transfer hot air rather than creating it from a fuel source, they can perform well above 100% efficiency. You should expect 30–40% savings on your heating expenses by installing a heat pump.
