How a Heat Pump Cools Your House

In Raleigh, heat pumps can be a popular choice to heat and cool your residence.

They appear about the same as an air conditioner. In fact, they work in the same way during the summer. Since they have a reversing valve, they can shift warmth in the opposite direction as well as heat your residence when temperatures drop.

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 you discover you have a heat pump, or you’re thinking over getting one, find out how this HVAC equipment keeps homes comfortable.

How Heat Pumps Work

Heat pumps use a refrigeration system much like an air conditioner. Most can run similar to a ductless mini-split, because 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 shift warmth. The outdoor unit also uses a compressor and is surrounded by metal fins that work as a heat sink to help transfer humidity properly.

Summertime Cooling

When your heat pump is cooling, the refrigerant is in the evaporator coil. Air from indoors moves over the coil, and the refrigerant sucks out heat. Wetness in the air also condenses on the coil, falling into the condensate pan below and flows away. The resulting cold air moves through the ductwork and back into your home.

At the same time, the refrigerant passes through a compressor on its way to the outdoor coil. This compresses the refrigerant, forcing it to get hotter. As it goes through the condensing coil, the outdoor fan and metal fins help to discharge heat to the outdoors. The refrigerant travels back into your house, passing through an expansion valve that chills it considerably, preparing it to start the process from the start.

When your heat pump is replaced and maintained correctly, you’ll get efficient cooling equivalent to a high-performance air conditioner.

Wintertime Heating

In heating mode, the heat exchange process takes place the opposite way. By traveling in the opposing direction, refrigerant extracts heat from the outdoor air and disperses it into your home to warm the inside.

Heat pumps running in heating mode are most effective when the temperature remains above freezing outside. If it turns too cold, a backup electric resistance heater starts to keep your house comfy, but your heating expenses go up as a result.

Heat pumps are on longer than furnaces because the air doesn’t get as warm. This helps sustain a more balanced indoor temperature. Also, because heat pumps transfer heat rather than creating it from a fuel source, they can work well above 100% efficiency. You can anticipate 30–40% savings on your heating costs by using a heat pump.
