How a Heat Pump Cools Your House

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

They seem almost like an air conditioner. In fact, they run in a similar fashion during high temperatures. Since they have a reversing valve, they can shift humidity 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? Just track down the model number on the outdoor unit and check it online. If it turns out you use a heat pump, or you’re thinking over buying one, find out how this HVAC unit keeps homes cozy.

How Heat Pumps Operate

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

Summertime Cooling

In cooling mode, the refrigerant starts in the evaporator coil. Air from indoors moves over the coil, and the refrigerant sucks out warmth. Wetness in the air also condenses on the coil, falling into the condensate pan below and flows away. The following dehumidified air flows through the ductwork and back into your residence.

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 goes 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 cools it greatly, readying it to begin the process from the start.

When your heat pump is put in and maintained appropriately, you’ll receive efficient cooling similar to a high-performance air conditioner.

Wintertime Heating

When your heat pump is set to heat, the heat exchange procedure happens the other way around. By traveling in the opposite direction, refrigerant removes heat from the outdoor air and vents it into your home to warm the inside.

Heat pumps operating 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 house cozy, but your heating bills go up as a result.

Heat pumps are on longer than furnaces since the air doesn’t get as heated. This helps keep a more stable indoor temperature. Additionally, because heat pumps shift heat rather than generating it from a fuel source, they can perform well above 100% efficiency. You can anticipate 30–40% savings on your heating costs by installing a heat pump.
