For homes in mild climates, heat pumps are an attractive solution for both heating and cooling. This unique all-in-one unit transfers heat from one location to another to maintain a desired indoor temperature year-round. If you’re accustomed to switching from a furnace during the winter to an AC compressor once the Southern heat rolls back around, it’s helpful to learn more about this technology. 

Circulation of Refrigerant

To transfer heat effectively, heat pumps use evaporation and condensation. A chemical called refrigerant is pumped through this cycle to absorb heat. The refrigerant and hot air move through a series of exchange coils. In one coil, the refrigerant reaches a low pressure so it can evaporate and better absorb heat. In the other coil, it condenses and releases heat.

How It Works Year-Round

Depending on the outdoor temperature, the heat pump will either move the heat from the indoor environment and place it outside or pull warm air from the outdoors and bring it into the home. This is because the entire evaporation and condensation cycle is reversible within the device. Even when the outside air is cool, the system can still extract some warmth from it. Much like a AC compressor, heat pumps also dehumidify a home during warm weather.

Both ground-source and air-source heat pumps are available. Known also as geothermal pumps, ground-source devices work the same way as traditional air-source pumps except for the fact that they exchange heat from the home to the ground and vice versa. In moderate climates, air pumps suffice, as the air remains warm enough even during winter months to provide the home with all the heat it needs.
