How a Heat Pump Cools Your House

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

They seem about the same as an air conditioner. In actuality, they run in a similar fashion during warm weather. Due to a reversing valve, they can transfer warmth in the opposite direction as well as add comfort to your residence 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 discover you use a heat pump, or you’re thinking about getting one, find out how this HVAC equipment keeps houses comfortable.

How Heat Pumps Work

Heat pumps depend on a refrigeration system like an air conditioner. Most can work like a ductless mini-split, as 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 shift humidity. The outdoor unit also uses a compressor and is enclosed 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 indoors is distributed over the coil, and the refrigerant removes 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 constricts the refrigerant, forcing 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 exterior. The refrigerant moves back indoors, moving through an expansion valve that cools it greatly, prepping it to start the process all over again.

When your heat pump is replaced and maintained properly, you’ll get efficient cooling similar to an energy-saving air conditioner.

Wintertime Heating

When your heat pump is heating, 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 working 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 house comfy, but your heating bills go up as a result.

Heat pumps run longer than furnaces as the air doesn’t turn as hot. This helps sustain a more balanced indoor temperature. Also, because heat pumps transfer warmth rather than generating it from a fuel source, they can operate well above 100% efficiency. You should receive 30–40% savings on your heating costs by getting a heat pump.
