How a Heat Pump Cools Your Residence

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

They seem almost like an air conditioner. In fact, they operate in the same way during the summer. Due to a reversing valve, they can transfer warmth in the opposite direction as well as heat your house when it's cold.

How Heat Pumps Run

Heat pumps have a refrigeration system like an air conditioner. Most can run similar 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 sent through these coils to move warmth. The outdoor unit also contains a compressor and is enclosed by metal fins that function as a heat sink to help shift heat properly.

Summertime Cooling

When your heat pump is cooling, the refrigerant is in the evaporator coil. Air from inside the house moves over the coil, and the refrigerant extracts heat. Wetness in the air also condenses on the coil, falling into the condensate pan below and flows away. The ensuing cool air circulates through the ductwork and back into your residence.

Meanwhile, the refrigerant passes through a compressor on its way to the outdoor coil. This constricts the refrigerant, causing it to warm up. As it goes through the condensing coil, the outdoor fan and metal fins help to discharge heat to the exterior. The refrigerant heads back into your house, moving through an expansion valve that chills it considerably, readying it to go through the process all over again.

When your heat pump is installed and maintained appropriately, you’ll get efficient cooling on par with a high-performance air conditioner.

Wintertime Heating

In heating mode, the heat exchange cycle takes place the opposite way. By flowing in the opposite direction, refrigerant removes heat from the outdoor air and adds it into your residence to warm the interior.

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

Heat pumps run longer than furnaces because the air doesn’t become as heated. This helps sustain a more even indoor temperature. On top of that, because heat pumps move hot air rather than making it from a fuel source, they can work well above 100% efficiency. You should expect 30–40% savings on your heating bills by using a heat pump.
