How a Heat Pump Cools Your House

In Austin, heat pumps can be a popular choice to heat and cool your home.

They seem almost like an air conditioner. In actuality, they run in a similar fashion during warm weather. Due to a reversing valve, they can shift humidity in the opposite direction as well as add warmth to your house in the winter.

Not sure if you use a heat pump or an air conditioner? Just find the model number on the outdoor unit and run it online. If you find you own a heat pump, or you’re thinking about buying one, find out how this HVAC equipment keeps residences comfortable.

How Heat Pumps Work

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

Summertime Cooling

In cooling mode, the refrigerant starts in the evaporator coil. Air from within the house is distributed over the coil, and the refrigerant sucks out heat. Wetness in the air also condenses on the coil, dripping into the condensate pan below and drains away. The following cool air circulates through the ductwork and back into your home.

Meanwhile, the refrigerant moves a compressor on its way to the outdoor coil. This concentrates the refrigerant, forcing it to heat up even more. As it goes through the condensing coil, the outside fan and metal fins help to emit heat to the exterior. The refrigerant moves back indoors, moving through an expansion valve that cools it greatly, prepping it to go through the process all over again.

When your heat pump is put in and maintained appropriately, you’ll get efficient cooling as good as an energy-efficient air conditioner.

Wintertime Heating

When your heat pump is set to heat, the heat exchange process happens the opposite way. By traveling in the opposite direction, refrigerant pulls 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 starts to keep your house cozy, but your heating bills go up as a result.

Heat pumps are on longer than furnaces since the air doesn’t turn as hot. This helps keep a more balanced indoor temperature. Also, because heat pumps shift hot air rather than generating it from a fuel source, they can operate well above 100% efficiency. You can anticipate 30–40% savings on your heating costs by switching to a heat pump.
