How a Heat Pump Cools Your House

In Oakville, heat pumps can be a popular option for heating and cooling your home.

They seem about the same as an air conditioner. In fact, they work in a similar fashion during the summer. Because of a reversing valve, they can move humidity in the opposite direction as well as add comfort to your home when it's cold.

Not sure if you use a heat pump or an air conditioner? Simply locate the model number on the outdoor unit and check it online. If you discover you use a heat pump, or you’re considering purchasing one, find out how this HVAC system keeps residences comfy.

How Heat Pumps Work

Heat pumps use a refrigeration system like an air conditioner. Most can run similar to a ductless mini-split, because they can heat and cool. Heat pumps use an indoor evaporator coil and an outdoor condensing coil. Refrigerant is pumped through these coils to move heat. The outdoor unit also has a compressor and is surrounded by metal fins that work as a heat sink to help shift humidity efficiently.

Summertime Cooling

In cooling mode, the refrigerant is in the evaporator coil. Air from within the house is set over the coil, and the refrigerant extracts warmth. Moisture in the air also condenses on the coil, dropping into the condensate pan below and flows away. The resulting cool air flows through the ductwork and back into your home.

During this time, the refrigerant flows a compressor on its way to the outdoor coil. This constricts the refrigerant, forcing it to heat up even more. As it goes through the condensing coil, the exterior fan and metal fins help to discharge heat to the outside. The refrigerant moves back into your house, moving through an expansion valve that cools it significantly, prepping it to start the process from the start.

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

Wintertime Heating

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

Heat pumps working in heating mode are most effective when the temperature is warmer than freezing outside. If it gets too cold, a backup electric resistance heater starts to keep your house comfortable, but your heating bills go up as a result.

Heat pumps operate longer than furnaces as the air doesn’t turn as heated. This helps sustain a more stable indoor temperature. Also, because heat pumps shift hot air rather than creating it from a fuel source, they can perform well above 100% efficiency. You should receive 30–40% savings on your heating expenses by switching to a heat pump.
