How a Heat Pump Cools Your House

In Grand Island, heat pumps can be a popular option for heating and cooling your house.

They seem almost like an air conditioner. In fact, they operate in a similar fashion during hot weather. Because of a reversing valve, they can move humidity in the opposite direction as well as add comfort to your home in the winter.

Not sure if you use a heat pump or an air conditioner? Just find the model number on the outdoor unit and run it online. If you discover you own a heat pump, or you’re thinking about installing one, find out how this HVAC unit keeps houses comfortable.

How Heat Pumps Run

Heat pumps use a refrigeration system much like an air conditioner. Most can work like a ductless mini-split, because they can heat and cool. Heat pumps rely on an indoor evaporator coil and an outdoor condensing coil. Refrigerant is moved through these coils to move humidity. The outdoor unit also contains a compressor and is enclosed by metal fins that function as a heat sink to help move humidity properly.

Summertime Cooling

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

During this time, the refrigerant flows a compressor on its way to the outdoor coil. This constricts the refrigerant, leading it to get hotter. As it flows through the condensing coil, the exterior fan and metal fins help to discharge heat to the outdoors. The refrigerant moves back indoors, traveling through an expansion valve that cools it considerably, preparing it to go through the process from the beginning.

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

Wintertime Heating

When your heat pump is set to heat, the heat exchange procedure takes place in reverse. By moving in a different direction, refrigerant extracts heat from the outdoor air and adds it into your home to warm rooms.

Heat pumps operating in heating mode are most efficient when the temperature is warmer than freezing outside. If it turns too cold, a backup electric resistance heater kicks on to keep your home cozy, but your heating expenses go up as a result.

Heat pumps operate longer than furnaces because the air doesn’t become as warm. This helps maintain a more balanced indoor temperature. Additionally, because heat pumps transfer warmth rather than making it from a fuel source, they can work well above 100% efficiency. You should receive 30–40% savings on your heating costs by switching to a heat pump.
