A loop in the ground and a steady temperature
Inside the earth, temperatures stay relatively constant through the year, and a geothermal system taps into that. R.A. Heating & Air Conditioning installs systems that run fluid through a loop buried underground. In winter they warm your house from that steady source, and in summer they dispel heat from your home.
The fluid in the loop carries the ground's temperature to the house. Inside, it circulates through water-to-refrigerant and refrigerant-to-air heat exchangers, where those fluid temperatures are converted into hot or cool air for your rooms. It is a different machine from the condenser that sits beside most houses.
