How a Heat Pump Cools Your Home

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

They look about the same as an air conditioner. In fact, they work in a similar fashion during hot weather. Because of a reversing valve, they can move heat in the opposite direction as well as add warmth to your house when it's cold.

Not sure if you rely on a heat pump or an air conditioner? Just locate the model number on the outdoor unit and run it online. If you discover you have a heat pump, or you’re thinking over getting one, find out how this HVAC system keeps homes comfy.

How Heat Pumps Work

Heat pumps use a refrigeration system like an air conditioner. Most can work like 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 sent through these coils to move warmth. The outdoor unit also has a compressor and is surrounded by metal fins that act as a heat sink to help move humidity properly.

Summertime Cooling

In cooling mode, the refrigerant starts in the evaporator coil. Air from inside the house is set over the coil, and the refrigerant extracts warmth. Moisture in the air also condenses on the coil, falling into the condensate pan below and drains away. The following dehumidified air moves through the ductwork and back into your residence.

During this time, the refrigerant flows a compressor on its way to the outdoor coil. This constricts the refrigerant, forcing it to get hotter. As it flows through the condensing coil, the outside fan and metal fins help to discharge heat to the exterior. The refrigerant travels back inside, passing through an expansion valve that cools it considerably, preparing it to start the process from the beginning.

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

Wintertime Heating

When your heat pump is heating, the heat exchange procedure occurs the opposite way. By flowing in the opposing direction, refrigerant extracts heat from the outdoor air and adds it into your home to warm the interior.

Heat pumps running in heating mode are most efficient 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 run longer than furnaces because the air doesn’t turn as warm. This helps sustain 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 bills by switching to a heat pump.
