How a Heat Pump Cools Your Home

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

They look almost like an air conditioner. In reality, they run in the same way during high temperatures. Because of a reversing valve, they can shift 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? All you have to do is track down the model number on the outdoor unit and check it online. If it turns out you have a heat pump, or you’re considering installing one, find out how this HVAC equipment keeps homes comfy.

How Heat Pumps Run

Heat pumps have a refrigeration system similar to an air conditioner. Most can operate akin to a ductless mini-split, as 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 has a compressor and is surrounded by metal fins that act as a heat sink to help transfer humidity effectively.

Summertime Cooling

When your heat pump is cooling, the refrigerant is in the evaporator coil. Air from within the house is distributed over the coil, and the refrigerant removes humidity. Water in the air also condenses on the coil, dropping into the condensate pan below and flows away. The ensuing dehumidified air moves through the ductwork and back into your house.

At the same time, the refrigerant moves a compressor on its way to the outdoor coil. This concentrates the refrigerant, causing it to get hotter. As it moves through the condensing coil, the outside fan and metal fins help to emit heat to the outdoors. The refrigerant heads back into your house, passing through an expansion valve that cools it greatly, prepping it to start the process from the start.

When your heat pump is installed and maintained appropriately, you’ll get efficient cooling comparable to a high-performance air conditioner.

Wintertime Heating

When your heat pump is heating, the heat exchange process takes place the other way around. By moving in the opposite direction, refrigerant extracts heat from the outdoor air and vents it into your residence to warm the interior.

Heat pumps operating in heating mode are most efficient when the temperature remains above freezing outside. If it gets too frigid, a backup electric resistance heater kicks on to keep your home comfy, but your heating costs go up as a result.

Heat pumps work longer than furnaces since the air doesn’t turn as heated. This helps keep a more balanced indoor temperature. Additionally, because heat pumps move heat rather than generating it from a fuel source, they can operate well above 100% efficiency. You should receive 30–40% savings on your heating bills by using a heat pump.
