How a Heat Pump Cools Your House

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

They look almost like an air conditioner. In fact, they run in a nearly identical way during high temperatures. Since they have a reversing valve, they can transfer heat in the opposite direction as well as add warmth to your residence when it's cold.

Not sure if you use a heat pump or an air conditioner? Just locate the model number on the outdoor unit and look it up online. If it turns out you have a heat pump, or you’re thinking about installing one, find out how this HVAC unit keeps residences cozy.

How Heat Pumps Operate

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

Summertime Cooling

When your heat pump is set to cooling, the refrigerant starts in the evaporator coil. Air from within the house moves over the coil, and the refrigerant extracts humidity. Moisture in the air also condenses on the coil, falling into the condensate pan below and flows away. The following dehumidified air circulates through the ductwork and back into your home.

Meanwhile, the refrigerant flows 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 exterior fan and metal fins help to emit heat to the outside. The refrigerant moves back into your house, moving through an expansion valve that cools it considerably, preparing it to start the process from the start.

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

Wintertime Heating

When your heat pump is set to heat, the heat exchange process occurs the opposite way. By traveling in the opposite direction, refrigerant extracts heat from the outdoor air and adds it into your home to warm the interior.

Heat pumps running in heating mode are most efficient when the temperature is warmer than freezing outside. If it gets too frigid, a backup electric resistance heater turns on to keep your residence cozy, but your heating expenses increase as a result.

Heat pumps work longer than furnaces since the air doesn’t become as heated. This helps keep a more balanced indoor temperature. On top of that, because heat pumps move warmth rather than making it from a fuel source, they can perform well above 100% efficiency. You can anticipate 30–40% savings on your heating expenses by installing a heat pump.
