How a Heat Pump Cools Your Home

In Rochester, heat pumps can be a popular solution for heating and cooling your home.

They seem very similar to an air conditioner. In actuality, they operate in a similar fashion during warm weather. Due to a reversing valve, they can shift warmth in the opposite direction as well as add comfort to your home when temperatures drop.

Not sure if you rely on a heat pump or an air conditioner? Simply track down the model number on the outdoor unit and look it up online. If it turns out you have a heat pump, or you’re considering buying one, discover how this HVAC equipment keeps homes comfortable.

How Heat Pumps Run

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

Summertime Cooling

When your heat pump is cooling, the refrigerant begins in the evaporator coil. Air from indoors blows over the coil, and the refrigerant sucks out heat. Moisture in the air also condenses on the coil, dripping into the condensate pan below and drains away. The ensuing cool air circulates through the ductwork and back into your home.

At the same time, the refrigerant moves a compressor on its way to the outdoor coil. This constricts the refrigerant, forcing it to get hotter. As it goes through the condensing coil, the outdoor fan and metal fins help to exhaust heat to the exterior. The refrigerant travels back inside, traveling through an expansion valve that chills it considerably, prepping it to go through the process from the start.

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

Wintertime Heating

In heating mode, the heat exchange procedure happens in reverse. By moving in a different direction, refrigerant extracts heat from the outdoor air and adds it into your residence to warm the interior.

Heat pumps running in heating mode are most efficient when the temperature is warmer than freezing outside. If it becomes too chilly, 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 since the air doesn’t become as heated. This helps keep a more stable indoor temperature. Also, because heat pumps move heat rather than generating it from a fuel source, they can work well above 100% efficiency. You should expect 30–40% savings on your heating costs by using a heat pump.
