How a Heat Pump Cools Your Home

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

They seem almost like an air conditioner. In reality, they run in a similar fashion during the summer. Since they have 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 have 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 own a heat pump, or you’re thinking about installing one, find out how this HVAC system keeps houses comfy.

How Heat Pumps Operate

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

Summertime Cooling

In cooling mode, the refrigerant begins in the evaporator coil. Air from within the house blows over the coil, and the refrigerant sucks out warmth. Moisture in the air also condenses on the coil, falling into the condensate pan below and moves away. The resulting dehumidified air flows through the ductwork and back into your home.

At the same time, the refrigerant flows 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 outdoor fan and metal fins help to exhaust heat to the exterior. The refrigerant travels back inside, moving through an expansion valve that cools it significantly, preparing it to begin the process all over again.

When your heat pump is put in and maintained correctly, you’ll receive efficient cooling equivalent to an energy-efficient air conditioner.

Wintertime Heating

When your heat pump is set to heat, the heat exchange process occurs in reverse. By moving in a different direction, refrigerant extracts heat from the outdoor air and disperses it into your house to warm the inside.

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

Heat pumps are on longer than furnaces since the air doesn’t get as warm. This helps maintain a more stable indoor temperature. On top of that, because heat pumps shift warmth rather than generating it from a fuel source, they can work well above 100% efficiency. You should receive 30–40% savings on your heating expenses by using a heat pump.
