How a Heat Pump Cools Your House

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

They appear almost like an air conditioner. In reality, they operate in the same way during hot weather. Because of 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? All you have to do is find 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 buying one, discover how this HVAC unit keeps houses comfortable.

How Heat Pumps Run

Heat pumps rely on a refrigeration system similar to an air conditioner. Most can operate like 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 move humidity. The outdoor unit also contains a compressor and is encircled by metal fins that act as a heat sink to help move humidity effectively.

Summertime Cooling

When your heat pump is cooling, the refrigerant begins in the evaporator coil. Air from indoors is set over the coil, and the refrigerant extracts heat. Moisture in the air also condenses on the coil, dropping into the condensate pan below and flows away. The following cool air flows through the ductwork and back into your home.

During this time, the refrigerant flows a compressor on its way to the outdoor coil. This compresses the refrigerant, leading it to heat up even more. As it moves through the condensing coil, the outdoor fan and metal fins help to exhaust heat to the outside. The refrigerant moves back indoors, traveling through an expansion valve that chills it considerably, readying it to begin the process from the beginning.

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

Wintertime Heating

In heating mode, the heat exchange process happens the opposite way. By flowing in a different direction, refrigerant pulls heat from the outdoor air and adds it into your home to warm rooms.

Heat pumps working in heating mode are most useful when the temperature remains above freezing outside. If it gets too chilly, a backup electric resistance heater kicks on to keep your residence comfy, but your heating expenses increase as a result.

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