How a Heat Pump Cools Your Home

In Waldorf, heat pumps can be a popular solution for heating and cooling your house.

They appear about the same as an air conditioner. In fact, they run in a nearly identical way during the summer. Since they have a reversing valve, they can shift warmth in the opposite direction as well as heat your home when it's cold.

Not sure if you rely on a heat pump or an air conditioner? All you need to do is track down the model number on the outdoor unit and run it online. If you discover you have a heat pump, or you’re thinking about purchasing one, find out how this HVAC system keeps homes cozy.

How Heat Pumps Run

Heat pumps depend on a refrigeration system much like an air conditioner. Most can operate like a ductless mini-split, since they can heat and cool. Heat pumps use an indoor evaporator coil and an outdoor condensing coil. Refrigerant is sent through these coils to transfer humidity. The outdoor unit also uses a compressor and is encircled by metal fins that work as a heat sink to help shift heat effectively.

Summertime Cooling

When your heat pump is set to cooling, the refrigerant begins in the evaporator coil. Air from inside the house is distributed over the coil, and the refrigerant sucks out warmth. Water in the air also condenses on the coil, falling into the condensate pan below and drains away. The following cold air moves through the ductwork and back into your residence.

At the same time, the refrigerant moves a compressor on its way to the outdoor coil. This concentrates the refrigerant, forcing it to heat up even more. As it flows through the condensing coil, the exterior fan and metal fins help to exhaust heat to the outdoors. The refrigerant moves back into your house, traveling through an expansion valve that lowers its temperature it greatly, readying it to start the process all over again.

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

Wintertime Heating

In heating mode, the heat exchange process occurs the opposite way. By flowing in the opposite direction, refrigerant removes heat from the outdoor air and adds it into your residence to warm rooms.

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

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