How a Heat Pump Cools Your House

In Fort Wayne, heat pumps can be a popular option for heating and cooling your residence.

They seem almost like an air conditioner. In reality, they work in the same way during high temperatures. Since they have a reversing valve, they can transfer warmth in the opposite direction as well as heat your home when temperatures drop.

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 run it online. If it turns out you have a heat pump, or you’re considering buying one, learn more about how this HVAC equipment keeps residences comfy.

How Heat Pumps Run

Heat pumps rely on a refrigeration system similar to an air conditioner. Most can run akin to a ductless mini-split, as they can heat and cool. Heat pumps use an indoor evaporator coil and an outdoor condensing coil. Refrigerant is sent through these coils to transfer warmth. The outdoor unit also uses a compressor and is surrounded by metal fins that function as a heat sink to help shift warmth efficiently.

Summertime Cooling

When your heat pump is cooling, the refrigerant begins in the evaporator coil. Air from within the house moves 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 cold air circulates through the ductwork and back into your house.

During this time, the refrigerant moves a compressor on its way to the outdoor coil. This constricts the refrigerant, causing it to warm up. As it flows through the condensing coil, the outdoor fan and metal fins help to emit heat to the outside. The refrigerant heads back inside, traveling through an expansion valve that chills it greatly, prepping it to begin the process all over again.

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

Wintertime Heating

When your heat pump is heating, the heat exchange cycle happens the opposite way. By traveling in the opposite direction, refrigerant extracts heat from the outdoor air and disperses it into your residence 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 cold, a backup electric resistance heater starts to keep your residence comfy, but your heating expenses go up as a result.

Heat pumps work longer than furnaces as the air doesn’t become as warm. This helps maintain a more stable indoor temperature. On top of that, because heat pumps transfer warmth rather than creating it from a fuel source, they can work well above 100% efficiency. You should receive 30–40% savings on your heating costs by getting a heat pump.
