How Well Does Geothermal Cooling Work?

Geothermal cooling saves money and energy in cooling one’s home.

Geothermal systems are becoming a more popular heating and cooling option among homeowners in recent years, most famous for their energy efficiency. They also perform heating and cooling in the same system, so one only needs one appliance instead of two. As summer rolls around, or if you have memories of a sweltering home with high AC costs, you might be thinking about a better way to cool your house during this time. Understanding how geothermal cooling works helps one see why it truly is an excellent invention.

How Geothermal AC Works

Air conditioners typically cool a room by taking the heat out of the space and blowing the cooled air back in. With a geothermal system, the heat pump which warms the home in winter works in reverse to maintain a comfortable temperature. Instead of taking heat from the earth into the house, it pumps heat back into the earth. In other words, the heat pump is recharging the battery to draw heat from the ground again come winter. Technically speaking, the heat pump transfers the heat gathered in the refrigerant to the ground loop fluid, which releases the energy into the earth. 


Given the mechanics of geothermal cooling, one can begin to see how efficient it is. Instead of releasing heat into an already hot summer climate, a geothermal system puts it into a constantly temperate earth. The earth tends to stay at about 50 degrees Fahrenheit year-round and is a free source of cooling and heating energy. Because of this use of energy, the need for electrical powering is less than in conventional HVAC systems.


Your home will definitely see results with the right size and proper installation of a residential geothermal system. A professional geothermal installer will know how to size and position your system best for the best outcome, in summer and winter. Another positive of geothermal cooling is its quietness. Geothermal heat pumps are quiet machines and eliminate the need for a noisy outdoor condenser as well.

Low Maintenance

Geothermal cooling and heating work so well that they can last around 50 years, unlike traditional HVAC units, which might last between 20 and 30 years. As with the more common systems, though, one can enjoy it and not worry about it at all. Should problems arise, it likely will pertain to the heat pump rather than the underground pipes. That said, geothermal systems need very little maintenance on the whole.
