How a Heat Pump Cools Your Residence

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

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

Not sure if you have a heat pump or an air conditioner? All you need to do is track down the model number on the outdoor unit and run it online. If you discover you have a heat pump, or you’re considering installing one, learn more about how this HVAC system keeps homes comfy. 

How Heat Pumps Operate 

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

Summertime Cooling 

When your heat pump is set to cooling, the refrigerant is in the evaporator coil. Air from within the house moves over the coil, and the refrigerant extracts heat. Moisture in the air also condenses on the coil, falling into the condensate pan below and flows away. The ensuing cold air moves through the ductwork and back into your house. 

At the same time, the refrigerant passes through a compressor on its way to the outdoor coil. This constricts the refrigerant, forcing it to heat up even more. As it flows through the condensing coil, the outdoor fan and metal fins help to emit heat to the exterior. The refrigerant travels back into your house, passing through an expansion valve that chills it greatly, prepping it to begin the process all over again. 

When your heat pump is put in and maintained correctly, you’ll enjoy efficient cooling as good as a high-performance air conditioner. 

Wintertime Heating 

When your heat pump is heating, the heat exchange cycle takes place the opposite way. By moving in the opposite direction, refrigerant extracts heat from the outdoor air and vents it into your home to warm rooms. 

Heat pumps working in heating mode are most effective when the temperature is warmer than freezing outside. If it becomes too chilly, a backup electric resistance heater starts to keep your residence comfy, but your heating expenses increase as a result. 

Heat pumps work longer than furnaces because the air doesn’t become as hot. This helps sustain a more stable indoor temperature. Also, because heat pumps transfer hot air rather than generating it from a fuel source, they can work well above 100% efficiency. You can anticipate 30–40% savings on your heating bills by getting a heat pump.
