How a Heat Pump Cools Your House

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

They appear about the same as an air conditioner. In fact, they operate in a nearly identical way during the summer. Since they have a reversing valve, they can transfer heat in the opposite direction as well as heat your house when it's cold.

Not sure if you have a heat pump or an air conditioner? All you need to do is track down the model number on the outdoor unit and check it online. If it turns out you own a heat pump, or you’re thinking over getting one, discover how this HVAC system keeps homes comfy.

How Heat Pumps Operate

Heat pumps have a refrigeration system like 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 pumped through these coils to shift humidity. The outdoor unit also contains a compressor and is encircled by metal fins that function as a heat sink to help shift warmth effectively.

Summertime Cooling

In cooling mode, the refrigerant starts in the evaporator coil. Air from within the house is distributed over the coil, and the refrigerant extracts warmth. Moisture in the air also condenses on the coil, falling into the condensate pan below and moves away. The following cold air flows through the ductwork and back into your house.

Meanwhile, the refrigerant moves a compressor on its way to the outdoor coil. This concentrates the refrigerant, leading 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 travels back inside, traveling through an expansion valve that lowers its temperature it greatly, readying it to begin the process from the start.

When your heat pump is installed and maintained appropriately, you’ll have efficient cooling as good as an energy-efficient air conditioner.

Wintertime Heating

When your heat pump is set to heat, the heat exchange cycle happens the other way around. By moving in the opposing direction, refrigerant removes heat from the outdoor air and disperses it into your home to warm the interior.

Heat pumps running in heating mode are most effective when the temperature is above freezing outside. If it turns too cold, a backup electric resistance heater turns on to keep your house comfortable, but your heating expenses rise as a result.

Heat pumps work longer than furnaces as the air doesn’t turn as heated. This helps sustain a more balanced indoor temperature. Also, because heat pumps shift heat rather than generating it from a fuel source, they can work well above 100% efficiency. You can anticipate 30–40% savings on your heating bills by installing a heat pump.
