Building Value in Air - From The Beginning.

Corporate Offices and Facility 8

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. Their function, basically, is to move air in, out and around a building — making life inside a lot more pleasant.

Greenheck is also a major, multi-brand corporation, representing a number of other affiliated entities (Accurex, Airolite, Innovent, Precision Coils, and Valent) offering architectural louvers and sunshades, specialized air-handling systems, heating and cooling coils and many related accessories and services. (See Other Greenheck Corporate Brands.)

It's clear Greenheck has come a long way since 1947 when it began business as a tiny sheet metal shop in Schofield, Wisconsin. Today, Greenheck brand fans and ventilators, centrifugal and vane axial fans, make-up air units, energy-recovery ventilators, dampers, louvers, kitchen ventilation systems, laboratory exhaust systems, indoor air handling units, 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, Minnesota, North Carolina, Ohio, India, China and Mexico.

Founders Bernie and Bob Greenheck, though always determined to make their business grow, never imagined how large their enterprise would someday become. And grow it has. No other company offers a wider selection of these products. The company now achieves sales of approximately $500 million annually, employs more than 2,850 people, and utilizes more than 1.5 million square feet of manufacturing space. No matter how you measure it, Greenheck is number one in air movement and control.

Leading in Innovation

Achieving this leadership position is attributable in large part to Greenheck's long-standing commitment to consistently provide solutions to new industry challenges. Making ventilation and related equipment more energy-efficient, quieter, easier to install and maintain, and capable of the highest performance standards makes Greenheck the manufacturer others look to for the latest advances and ideas.

Growing demand for building projects that reflect "green" initiatives is impacting the ventilation industry. Greenheck was one of the first manufacturers of air-moving and control equipment to join the U.S. Green Building Council. Greenheck references the USGBC and ASHRAE guidelines and standards to identify specific products mechanical engineers can use when designing ventilation systems for sustainable-design projects and those adhering to LEED certification guidelines.

Investing in Itself

Greenheck consistently invests substantially in expansion and new facilities designed to better serve its customers. In recent years, Greenheck has steadily increased its manufacturing space, adding many thousands of square feet of capacity in Schofield and other U.S. locations, and in other countries. This growth is in response to ever-increasing demand for products that move air in, out, and through buildings.
