How a Heat Pump Cools Your Home

In Dallas, heat pumps can be a popular solution for heating and cooling your house. 

They appear about the same as an air conditioner. In fact, they run in a similar fashion during warm weather. Because of a reversing valve, they can shift warmth in the opposite direction as well as heat your house when it’s cold. 

Not sure if you have a heat pump or an air conditioner? All you have to do is locate the model number on the outdoor unit and check it online. If you discover you use a heat pump, or you’re considering purchasing one, find out how this HVAC system keeps houses comfortable. 

How Heat Pumps Run 

Heat pumps use a refrigeration system similar to an air conditioner. Most can run akin to a ductless mini-split, as they can heat and cool. Heat pumps use an indoor evaporator coil and an outdoor condensing coil. Refrigerant is moved 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 move warmth properly. 

Summertime Cooling 

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

At the same time, the refrigerant flows a compressor on its way to the outdoor coil. This compresses the refrigerant, leading it to warm up. As it moves through the condensing coil, the outdoor fan and metal fins help to discharge heat to the outside. The refrigerant moves back inside, moving through an expansion valve that chills it greatly, prepping it to start the process all over again. 

When your heat pump is put in and maintained correctly, you’ll get efficient cooling on par with an energy-efficient air conditioner. 

Wintertime Heating 

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

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

Heat pumps work longer than furnaces as the air doesn’t become as warm. This helps keep a more stable indoor temperature. Additionally, because heat pumps move warmth 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 installing a heat pump.
