How a Heat Pump Cools Your House

In Gainesville, heat pumps can be a popular option for heating and cooling your house.

They look about the same as an air conditioner. In fact, they work in a similar fashion during the summer. Due to a reversing valve, they can move humidity 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 find the model number on the outdoor unit and check it online. If you discover you have a heat pump, or you’re thinking over purchasing one, discover how this HVAC equipment keeps homes comfortable.

How Heat Pumps Run

Heat pumps depend on a refrigeration system similar to an air conditioner. Most can run akin to a ductless mini-split, because they can heat and cool. Heat pumps use an indoor evaporator coil and an outdoor condensing coil. Refrigerant is moved through these coils to shift warmth. The outdoor unit also has a compressor and is surrounded by metal fins that work as a heat sink to help move humidity effectively.

Summertime Cooling

When your heat pump is set to cooling, the refrigerant is in the evaporator coil. Air from within the house blows over the coil, and the refrigerant extracts warmth. Water in the air also condenses on the coil, dropping into the condensate pan below and flows away. The following dehumidified air circulates through the ductwork and back into your house.

During this time, the refrigerant passes through a compressor on its way to the outdoor coil. This concentrates the refrigerant, causing it to warm up. As it flows through the condensing coil, the exterior fan and metal fins help to exhaust heat to the exterior. The refrigerant travels back inside, traveling through an expansion valve that cools it greatly, readying it to begin the process all over again.

When your heat pump is installed and maintained appropriately, you’ll have efficient cooling comparable to a high-performance air conditioner.

Wintertime Heating

When your heat pump is set to heat, the heat exchange cycle takes place the other way around. By moving in the opposing direction, refrigerant extracts heat from the outdoor air and adds it into your house to warm the interior.

Heat pumps operating in heating mode are most effective when the temperature is above freezing outside. If it turns too frigid, a backup electric resistance heater kicks on to keep your house comfy, but your heating bills rise as a result.

Heat pumps run longer than furnaces since the air doesn’t become as hot. This helps maintain a more stable indoor temperature. Also, because heat pumps move warmth rather than generating it from a fuel source, they can operate well above 100% efficiency. You should expect 30–40% savings on your heating bills by installing a heat pump.
