What McGill AirFlow does

McGill AirFlow LLC is a US-based, family-owned manufacturer of commercial and industrial sheet metal ductwork for HVAC systems, founded in 1951 and headquartered in Columbus, Ohio. The company pioneered the manufacture and use of spiral duct and fittings for HVAC in the United States and remains the self-identified leading domestic producer of commercial and industrial sheet metal ductwork. Its product portfolio spans single-wall and double-wall round, flat oval, and rectangular ductwork; proprietary specialty lines including SilverGuard antimicrobial ductwork, Uni-Gasket self-sealing fittings, Uni-Coat PVC-coated steel, Uni-Quick movable duct systems, and Rectangular-k27 insulated rectangular duct; and ancillary components such as terminal outlets, dampers, access doors, silencers, and Leak Detective leakage-testing equipment.

The business operates five regional manufacturing plants (Iowa, Ohio, South Carolina, Texas, Vermont) combined with regional sales engineering offices covering all 50 US states, Puerto Rico, and Canadian provinces, supported by a Duct Express nationwide fulfillment service and proprietary Duct System Design engineering services. Revenue is generated through one-time B2B sales of manufactured ductwork and accessories to sheet metal contractors, design engineers, and project owners, with custom quoting on a project basis rather than published pricing. The customer base spans aviation (Delta Airlines), automotive (Mercedes-Benz), pharmaceutical (Becton Dickinson, Aspire Pharmaceutical), healthcare (St. Ann's Hospital), institutional (Herman Miller, Philadelphia Newspapers, Praxair, Webster Aquatic Center), and general commercial construction. The company remains privately held by the founding family with no external equity funding, no public listing, and no disclosed subsidiaries or M&A activity.
