What Greenheck Group does

Greenheck Group, operating through its legal entity Greenheck Fan Corporation, is a privately held US manufacturer of commercial air movement, control, and conditioning equipment founded in 1947 by WWII veterans Bob and Bernie Greenheck and headquartered in Schofield, Wisconsin. The company designs and builds fans, blowers, rooftop units, air terminal units, kitchen ventilation systems, dampers, louvers, dedicated outdoor air systems, fume exhaust systems, and air distribution products (grilles, registers, diffusers) marketed under six sub-brands — Greenheck, Accurex, Airolite, Innovent, Metalaire, and Valent — serving non-residential end markets including schools, hospitals, commercial kitchens, stadiums, laboratories, factories, data centers, multifamily housing, and OEM customers.

The company operates 15+ manufacturing facilities across the United States, Mexico (Saltillo), and India (Bawal), employing more than 5,500 people and managing approximately $530M in annual sourcing spend through dedicated business units (CF, FETI, DOAS, RTU, KVS, PRV, ATU, GRD). Its engineering platforms include Advanced Design Simulation (CFD/FEA-based), Advanced Materials and Strategic Technologies (AMAST), and a Manufacturing Execution System integrated with SAP. The portfolio includes a US-patented Automatic Airflow Balancing Valve and an A2L-refrigerant-compliant direct-fired heating and cooling unit, the first such compliant product in the commercial kitchen market.

Greenheck generates revenue primarily through engineered-to-order hardware sales to commercial construction, institutional, and industrial customers, priced via project quotes rather than published price lists. Go-to-market combines direct regional sales teams with a 200+ rep partner distribution network across the US and Latin America, supplemented by government cooperative purchasing access through Sourcewell contracts, OEM channels, and direct field sales for engineered solutions in healthcare, laboratories, and data centers. The company is executing a multi-year capacity expansion headlined by a $300M, 330-acre Knoxville, Tennessee campus, with a new Rooftop Unit business unit launched in 2025 marking the company's first greenfield BU.
