CASCADE, IA — When All Seasons Heating & Cooling, Dubuque, Iowa—a 75-employee sheet metal and mechanical contractor set up to do design builds or bid and spec jobs—was called to provide an HVAC solution for a newly constructed building at large agricultural farm in nearby Cascade, meeting with the facility owner and reviewing their wants and needs to determine the total design of a geothermal system was top priority. The main objectives included in-floor heat for the main farm shop, forced air heating and cooling for the offices and in-floor heat for the wash bay. The building consists of a very large farm shop, approximately 13,000 sq. ft. with 20 feet plus ceiling height; the office is approximately 1,200 sq. InstallationStarting the project in June 2023 and completing it in January 2024, All Seasons Heating & Cooling installed forced air and hydronic ClimateMaster geothermal units, which includes a 26-ton horizontal loop, or slinky loop as Fens describes it, installed under the back parking lot and farm field behind the building, dug in at about 10-12 feet in depth.
