How a Heat Pump Cools Your Home

In Jacksonville, heat pumps can be a popular choice to heat and cool your house. 

They appear almost like an air conditioner. In reality, 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 add warmth to 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 find you use a heat pump, or you’re considering purchasing one, find out how this HVAC system keeps homes cozy. 

How Heat Pumps Run 

Heat pumps use a refrigeration system like 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 pumped through these coils to shift warmth. The outdoor unit also uses a compressor and is enclosed by metal fins that function as a heat sink to help shift warmth properly. 

Summertime Cooling 

In cooling mode, the refrigerant starts in the evaporator coil. Air from indoors 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 moves away. The ensuing 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 concentrates the refrigerant, leading it to warm up. As it flows through the condensing coil, the outside fan and metal fins help to exhaust heat to the outdoors. The refrigerant moves back indoors, moving through an expansion valve that chills it considerably, prepping it to start the process from the beginning. 

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

Wintertime Heating 

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

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

Heat pumps work longer than furnaces as the air doesn’t become as warm. This helps maintain a more balanced indoor temperature. On top of that, 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.
