General Heating and Air Conditioning has significant experience with the design, development and installation of geothermal mechanical systems. A member of the Wisconsin Geothermal Association since 2001, General's largest scale, most impressive and most visible geothermal project is located in Verona, WI at Epic Systems Corporation. This multi-building campus embarked on a geothermal project with a scale not seen before in this area. Epic Systems' geothermal vertical bore field is to date the largest installation in the Midwest.

General, partnering with experienced and knowledgeable subcontractors, performed an installation that far exceeded anyone's expectations. The emergence, development and refinement of new approaches to energy usage and conservation are a continuous and ongoing process. At General, we are on the leading edge of new innovations taking place in core HVAC applications.
