How a Heat Pump Cools Your House

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

They seem almost like an air conditioner. In fact, they work in the same way during warm weather. Because of a reversing valve, they can transfer humidity in the opposite direction as well as add warmth to your home in the winter.

Not sure if you have a heat pump or an air conditioner? Simply locate the model number on the outdoor unit and check it online. If it turns out you own a heat pump, or you’re thinking over purchasing one, learn more about how this HVAC system keeps residences comfortable.

How Heat Pumps Run

Heat pumps use a refrigeration system similar to an air conditioner. Most can work akin to a ductless mini-split, because they can heat and cool. Heat pumps use an indoor evaporator coil and an outdoor condensing coil. Refrigerant is sent through these coils to transfer heat. The outdoor unit also has a compressor and is encircled by metal fins that act as a heat sink to help transfer warmth efficiently.

Summertime Cooling

In cooling mode, the refrigerant begins in the evaporator coil. Air from indoors is distributed over the coil, and the refrigerant removes humidity. Wetness in the air also condenses on the coil, dropping into the condensate pan below and drains away. The ensuing cold air flows through the ductwork and back into your house.

During this time, the refrigerant moves a compressor on its way to the outdoor coil. This compresses the refrigerant, causing it to get hotter. As it flows through the condensing coil, the outside fan and metal fins help to emit heat to the outside. The refrigerant heads back inside, moving through an expansion valve that lowers its temperature it significantly, preparing it to go through the process from the start.

When your heat pump is put in and maintained properly, you’ll get efficient cooling as good as an energy-saving air conditioner.

Wintertime Heating

When your heat pump is heating, the heat exchange process takes place the other way around. By traveling in the opposite direction, refrigerant pulls heat from the outdoor air and vents it into your home to warm the inside.

Heat pumps working in heating mode are most useful when the temperature is above freezing outside. If it turns too frigid, a backup electric resistance heater turns on to keep your home comfortable, but your heating costs increase as a result.

Heat pumps are on longer than furnaces since the air doesn’t become as warm. This helps sustain a more balanced indoor temperature. Additionally, because heat pumps shift hot air rather than generating it from a fuel source, they can operate well above 100% efficiency. You should expect 30–40% savings on your heating costs by using a heat pump.
