How a Heat Pump Cools Your House

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

They look very similar to an air conditioner. In actuality, they run in a similar fashion during hot weather. Due to a reversing valve, they can move warmth in the opposite direction as well as add warmth to your home when temperatures drop.

Not sure if you use a heat pump or an air conditioner? All you need to do is find the model number on the outdoor unit and look it up online. If you discover you use a heat pump, or you’re thinking about installing one, discover how this HVAC system keeps houses comfy.

How Heat Pumps Work

Heat pumps depend on a refrigeration system similar to an air conditioner. Most can operate akin 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 shift heat. The outdoor unit also contains a compressor and is enclosed by metal fins that function as a heat sink to help shift warmth efficiently.

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 moves away. The resulting cold air moves through the ductwork and back into your home.

During this time, the refrigerant flows a compressor on its way to the outdoor coil. This compresses the refrigerant, forcing it to warm up. As it goes through the condensing coil, the outside fan and metal fins help to emit heat to the outside. The refrigerant travels back indoors, passing through an expansion valve that cools it greatly, readying it to start the process from the beginning.

When your heat pump is put in and maintained correctly, you’ll receive efficient cooling comparable to a high-performance air conditioner.

Wintertime Heating

In heating mode, the heat exchange procedure takes place the opposite way. By moving in the opposite direction, refrigerant extracts heat from the outdoor air and adds it into your residence to warm the inside.

Heat pumps running in heating mode are most effective when the temperature remains above freezing outside. If it turns too frigid, a backup electric resistance heater turns on to keep your residence comfortable, but your heating expenses increase as a result.

Heat pumps are on longer than furnaces since the air doesn’t become as hot. This helps keep a more balanced indoor temperature. Additionally, because heat pumps shift warmth rather than making it from a fuel source, they can work well above 100% efficiency. You can anticipate 30–40% savings on your heating expenses by using a heat pump.
