Almy - Geothermal Heating & Cooling
Geothermal technology harnesses the Earth’s heat. Just a few feet below the surface, the Earth maintains a near-constant temperature, in contrast to the summer and winter extremes of the ambient air above ground. Like a cave, this ground temperature is warmer than the air above it during the winter and cooler than the air in the summer. Geothermal systems take advantage of this through heat exchange, act as heat sources in the winter and heat sinks in the summer
