How a Heat Pump Cools Your House

In Miami, heat pumps can be a popular choice to heat and cool your residence.

They seem almost like an air conditioner. In actuality, they operate in the same way during the summer. Due to a reversing valve, they can transfer heat in the opposite direction as well as add comfort to your house in the winter.

Not sure if you rely on a heat pump or an air conditioner? Just track down the model number on the outdoor unit and look it up online. If you discover you use a heat pump, or you’re thinking about getting one, learn more about how this HVAC equipment keeps houses cozy.

How Heat Pumps Run

Heat pumps use a refrigeration system much like an air conditioner. Most can operate similar to a ductless mini-split, because they can heat and cool. Heat pumps rely on an indoor evaporator coil and an outdoor condensing coil. Refrigerant is moved through these coils to move heat. The outdoor unit also contains a compressor and is encircled by metal fins that act as a heat sink to help move heat properly.

Summertime Cooling

In cooling mode, the refrigerant is in the evaporator coil. Air from indoors blows over the coil, and the refrigerant removes warmth. Moisture in the air also condenses on the coil, dropping into the condensate pan below and flows away. The ensuing dehumidified air flows through the ductwork and back into your home.

During this time, the refrigerant flows a compressor on its way to the outdoor coil. This constricts the refrigerant, causing it to heat up even more. As it moves through the condensing coil, the exterior fan and metal fins help to emit heat to the exterior. The refrigerant heads back indoors, moving through an expansion valve that cools it significantly, readying it to start the process from the beginning.

When your heat pump is put in and maintained appropriately, you’ll have efficient cooling on par with an energy-saving air conditioner.

Wintertime Heating

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

Heat pumps operating in heating mode are most useful when the temperature remains above freezing outside. If it becomes too chilly, a backup electric resistance heater starts to keep your residence comfy, but your heating bills rise as a result.

Heat pumps work longer than furnaces because the air doesn’t get as heated. This helps keep a more balanced indoor temperature. Additionally, because heat pumps move hot air rather than generating it from a fuel source, they can work well above 100% efficiency. You can anticipate 30–40% savings on your heating costs by getting a heat pump.
