How a Heat Pump Cools Your Residence

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 nearly identical way during hot weather. Since they have a reversing valve, they can move humidity in the opposite direction as well as add comfort to your home when temperatures drop.

Not sure if you use a heat pump or an air conditioner? All you need to do is track down the model number on the outdoor unit and check it online. If you find you use a heat pump, or you’re considering purchasing one, find out how this HVAC unit 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 shift heat. The outdoor unit also uses a compressor and is surrounded by metal fins that work as a heat sink to help move warmth 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 cold air moves through the ductwork and back into your home.

During this time, the refrigerant moves a compressor on its way to the outdoor coil. This constricts the refrigerant, leading it to heat up even more. As it moves through the condensing coil, the outside fan and metal fins help to emit heat to the outdoors. The refrigerant moves back indoors, traveling through an expansion valve that cools it significantly, prepping it to go through the process from the beginning.

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

Wintertime Heating

When your heat pump is set to heat, the heat exchange process happens the other way around. By moving in a different direction, refrigerant extracts heat from the outdoor air and adds it into your house to warm the inside.

Heat pumps running in heating mode are most useful when the temperature is above freezing outside. If it gets too cold, a backup electric resistance heater turns on to keep your residence comfortable, but your heating bills increase as a result.

Heat pumps operate longer than furnaces as the air doesn’t become as warm. This helps keep 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.
