How a Heat Pump Cools Your Home

In Austin, heat pumps can be a popular solution for heating and cooling your house.

They look about the same as an air conditioner. In reality, they operate in a nearly identical way during the summer. Because of a reversing valve, they can move humidity in the opposite direction as well as heat your residence when it's cold.

Not sure if you have a heat pump or an air conditioner? Simply locate the model number on the outdoor unit and check it online. If you discover you have a heat pump, or you’re thinking over buying one, find out how this HVAC system keeps residences comfy.

How Heat Pumps Operate

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

Summertime Cooling

In cooling mode, the refrigerant starts in the evaporator coil. Air from indoors is distributed over the coil, and the refrigerant sucks out humidity. Wetness in the air also condenses on the coil, dropping into the condensate pan below and moves away. The ensuing cool air flows through the ductwork and back into your house.

During this time, the refrigerant flows a compressor on its way to the outdoor coil. This concentrates the refrigerant, leading it to heat up even more. As it moves through the condensing coil, the exterior fan and metal fins help to exhaust heat to the outdoors. The refrigerant travels back indoors, moving through an expansion valve that chills it significantly, prepping it to go through the process from the start.

When your heat pump is put in and maintained appropriately, you’ll receive efficient cooling as good as a high-performance air conditioner.

Wintertime Heating

When your heat pump is heating, the heat exchange procedure occurs the other way around. By moving in a different direction, refrigerant pulls heat from the outdoor air and disperses it into your house to warm rooms.

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

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