Geothermal Permits

A GeoExchange System, commonly known as a Geothermal System, is a closed loop network of piping in the ground which circulates fluid allowing for heat transfer between a building HVAC system and the ground. GeoExchange systems can improve the energy efficiency of building heating and cooling systems through the use of a heat pump which can be more efficient than heating and cooling equipment in traditional HVAC systems.
