Greenheck is known worldwide as the leading manufacturer of air-movement and control equipment. Its flagship ventilation products are typically found behind walls, in ductwork or on the roofs of hospitals, office buildings, hotels, shopping malls, restaurants, schools, industrial plants and other commercial buildings.
Greenheck began business in 1947 as a tiny sheet metal shop in Schofield, Wisconsin. Today, Greenheck brand fans, energy-recovery ventilators, packaged ventilation, make-up air units, dampers, louvers, commercial kitchen ventilation, laboratory exhaust systems, and coils are shipped around the globe. Most of the company’s manufacturing still takes place in Schofield; additional manufacturing and assembly facilities are located in California, Kentucky, North Carolina, China, Mexico, and Delhi NCR Region, India.
