The term “geothermal heating” is now generally familiar. But the idea of using geothermal power to provide cooling might seem a bit strange, perhaps even counter-intuitive. However, using the mechanics of a geothermal heat pump (also known as a ground-source heat pump for reasons we will get into below), you can use the stable, clean, and renewable energy of the earth to cool down your home during summer. We’ll provide a brief explanation for how this works.
Installing a geothermal heat pump requires trained technicians and an extensive amount of labor that falls far outside the ability of amateurs.

A geothermal comfort system is a type of heat pump: it moves heat from one location and places it in another. By reversing the direction that the refrigerant moves, it reverses the direction the heat moves. In one mode, heat is moved inside and you have heating. In another, heat is moved outside and you have cooling.
A standard heat pump is an air-source pump that uses the air for its medium of exchange. It extracts heat from the outside air and moves it into a house, or it extracts heat from inside a house and moves it outside. But a geothermal heat pump is ground-source: it uses the earth as its medium of exchange, removing heat from the earth for its heating mode, and depositing heat into the earth for its cooling mode.
The indoor parts of a geothermal heat pump are similar to an air-source heat pump. The difference lies in the outdoor ground loops. These refrigerant lines are buried in the property around a house, either in horizontal or vertical configurations (depending on how much space is available). Some systems use chemical refrigerant to run through the pipes, but the majority circulate water. The temperature of the earth at the depth of the coils remains stable at around 55°F regardless of the surface temperature—this makes it ideal for air conditioning. It’s easy for the indoor coils to remove heat from the house—which is probably above 80°F—and move it into the cooler ground. When the winter comes, the still stable 55°F is a ready source for heating.

Find Out If Geothermal Is Your Best Option
The major drawback of a geothermal heat pump is that it isn’t ideal for all properties. The loops require significant space and the land itself may not be a good source of heat. And although geothermal heat pumps cost less to run than most heating and cooling systems, they do have a larger initial cost.
