What General Temperature Control, Inc. does

General Temperature Control, Inc. (GTC) is a privately held mechanical contractor founded in 1987 and headquartered in Canal Winchester, Ohio. The company designs, installs, and services heating, ventilation, and air-conditioning (HVAC) systems, plumbing, and sheet metal fabricated components for industrial, commercial, and institutional customers across Central Ohio. Notable technical capabilities include geothermal well-field installations (e.g., a 168-well system for Hocking College) and LEED-certified project delivery (London Middle School, Hocking College), positioning GTC within the energy-efficient and sustainable-building segment of regional mechanical contracting.

GTC employs a staff of 16, with technical personnel holding EPA, UA, and OSHA certifications. Its business model combines project-based mechanical construction — including large institutional work such as a 128,000-square-foot Ohio State University academic building and a 14,000-square-foot hospital addition — with recurring preventive-maintenance contracts, plumbing services, and emergency repair response. The company has formalized a workplace-safety partnership with the Ohio Bureau of Workers' Compensation. Customers span education (Ohio State University, Hocking College, London Middle School), healthcare, industrial, and government (Ohio National Guard) end markets.

The company makes money primarily through fixed-price mechanical construction contracts and recurring service agreements, with revenue concentrated in the Central Ohio region. No external funding, M&A activity, or recent leadership changes are documented, and the company's web presence shows a 2012 copyright date, indicating limited recent digital or marketing investment. An open Sales Account Executive requisition is the most observable forward-looking growth signal.
