How a Heat Pump Cools Your Home

In Longmont, heat pumps can be a popular solution for heating and cooling your residence.

They seem almost like an air conditioner. In reality, they work in the same way during warm weather. Because of a reversing valve, they can move heat in the opposite direction as well as add warmth to your residence when temperatures drop.

Not sure if you use a heat pump or an air conditioner? Just track down the model number on the outdoor unit and run it online. If it turns out you have a heat pump, or you’re thinking over buying one, learn more about how this HVAC equipment keeps residences cozy.

How Heat Pumps Work

Heat pumps depend on a refrigeration system like an air conditioner. Most can work akin to a ductless mini-split, as they can heat and cool. Heat pumps have an indoor evaporator coil and an outdoor condensing coil. Refrigerant is moved through these coils to transfer warmth. The outdoor unit also has a compressor and is enclosed by metal fins that work as a heat sink to help move heat properly.

Summertime Cooling

When your heat pump is cooling, the refrigerant starts in the evaporator coil. Air from within the house moves over the coil, and the refrigerant removes heat. Water in the air also condenses on the coil, dripping into the condensate pan below and drains away. The ensuing cold air circulates through the ductwork and back into your home.

Meanwhile, the refrigerant passes through a compressor on its way to the outdoor coil. This compresses the refrigerant, forcing it to heat up even more. As it moves through the condensing coil, the exterior fan and metal fins help to discharge heat to the outside. The refrigerant heads back inside, moving through an expansion valve that lowers its temperature it considerably, prepping it to start the process from the beginning.

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

Wintertime Heating

When your heat pump is set to heat, the heat exchange procedure happens in reverse. By moving in the opposing direction, refrigerant removes heat from the outdoor air and vents it into your home to warm the inside.

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

Heat pumps work longer than furnaces since the air doesn’t get as warm. This helps keep a more even indoor temperature. Additionally, because heat pumps shift warmth rather than generating it from a fuel source, they can perform well above 100% efficiency. You should expect 30–40% savings on your heating costs by switching to a heat pump.
