How a Heat Pump Cools Your Home

In Louisville, heat pumps can be a popular option for heating and cooling your home.

They look almost like an air conditioner. In reality, they run in the same way during warm weather. Due to a reversing valve, they can shift humidity in the opposite direction as well as add comfort to your house in the winter.

Not sure if you have a heat pump or an air conditioner? All you have to do is 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 purchasing one, learn more about how this HVAC equipment keeps homes comfortable.

How Heat Pumps Operate

Heat pumps rely on a refrigeration system much like an air conditioner. Most can run akin to a ductless mini-split, since they can heat and cool. Heat pumps rely on an indoor evaporator coil and an outdoor condensing coil. Refrigerant is sent through these coils to shift humidity. The outdoor unit also uses a compressor and is encircled by metal fins that act as a heat sink to help transfer humidity effectively.

Summertime Cooling

When your heat pump is cooling, the refrigerant begins in the evaporator coil. Air from inside the house blows over the coil, and the refrigerant extracts humidity. Water in the air also condenses on the coil, dripping into the condensate pan below and flows away. The resulting cool air flows through the ductwork and back into your residence.

During this time, the refrigerant passes through a compressor on its way to the outdoor coil. This compresses the refrigerant, causing it to heat up even more. As it moves through the condensing coil, the outside fan and metal fins help to discharge heat to the outside. The refrigerant moves back inside, traveling through an expansion valve that cools it significantly, prepping it to begin the process from the beginning.

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

Wintertime Heating

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

Heat pumps operating in heating mode are most useful when the temperature remains above freezing outside. If it gets too frigid, a backup electric resistance heater kicks on to keep your house comfortable, but your heating expenses increase as a result.

Heat pumps operate longer than furnaces since the air doesn’t become as heated. This helps sustain a more even indoor temperature. Also, because heat pumps shift heat rather than making it from a fuel source, they can perform well above 100% efficiency. You should expect 30–40% savings on your heating expenses by installing a heat pump.
