Your Local Source for Geothermal Heating and Cooling

When we dig four to six feet below the ground, temperatures will remain relatively constant year-round. A geothermal system consists of an indoor handling unit and a buried system of pipes called an earth loop or pump to reinjection well.

The pipes on the earth loop are usually made of polyethylene and, depending on the job site, either buried horizontally or vertically. The AAA Heating & Air Conditioning Inc engineers may prefer to design an "open-loop" system if an aquifer is available, meaning that we drill a well into the underground water. Then water is pumped up, ran past a heat exchanger, and then the water returns to the same aquifer through "reinjection."

During the winter, fluid circulating through the system's earth loop or well absorbs stored heat from the ground and carries it indoors. The indoor unit compresses the heat to a higher temperature and distributes back through the building. In the summer, the geothermal HVAC system pulls heat from the building and carries it through the earth loop/pump reinjection well, where it deposits the heat into the cooler earth/aquifer.
