How a Heat Pump Cools Your Home

In Mobile, heat pumps can be a popular solution for heating and cooling your home.

They appear almost like an air conditioner. In actuality, they operate in the same way during the summer. Due to a reversing valve, they can shift heat in the opposite direction as well as heat your house when it's cold.

Not sure if you rely on a heat pump or an air conditioner? Just find the model number on the outdoor unit and look it up online. If you discover you own a heat pump, or you’re considering purchasing one, find out how this HVAC equipment keeps residences comfy.

How Heat Pumps Run

Heat pumps depend on a refrigeration system much like an air conditioner. Most can work like 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

When your heat pump is cooling, the refrigerant starts in the evaporator coil. Air from inside the house moves over the coil, and the refrigerant sucks out warmth. Wetness in the air also condenses on the coil, falling into the condensate pan below and flows away. The ensuing cold air circulates through the ductwork and back into your house.

At the same time, the refrigerant moves a compressor on its way to the outdoor coil. This constricts the refrigerant, causing it to get hotter. As it flows through the condensing coil, the outdoor fan and metal fins help to exhaust heat to the outdoors. The refrigerant heads back into your house, moving through an expansion valve that cools it greatly, preparing it to start the process all over again.

When your heat pump is put in and maintained correctly, you’ll receive efficient cooling on par with a high-performance air conditioner.

Wintertime Heating

When your heat pump is heating, the heat exchange cycle happens the opposite way. By flowing in the opposite direction, refrigerant extracts heat from the outdoor air and vents it into your home to warm the interior.

Heat pumps operating in heating mode are most effective when the temperature remains above freezing outside. If it turns too chilly, a backup electric resistance heater turns on to keep your house comfortable, but your heating expenses rise as a result.

Heat pumps run longer than furnaces because the air doesn’t get as heated. This helps maintain a more balanced indoor temperature. On top of that, because heat pumps transfer hot air rather than creating it from a fuel source, they can operate well above 100% efficiency. You can anticipate 30–40% savings on your heating costs by getting a heat pump.
