What Air Source does
Air Source is a private, for-profit LLC founded in 2009 and headquartered in Dover, New Hampshire. The company specializes exclusively in industrial and commercial sheet metal ductwork: design, fabrication, and installation, operating as a specialty trade sub-contractor for general contractors and mechanical contractors across Northern New England (New Hampshire, Massachusetts, and Maine). Its service scope spans HVAC ductwork, process piping and ventilation, clean room fabrication, stainless steel fabrication, modular welding, phased retrofit/replacement, and building automation integration. The technical approach is built on AutoCAD-based design with 3D modeling for coordination, fabrication drawings, and field layout.
The company serves enterprise end-customers across multiple verticals, including healthcare, education, biotech, industrial, retail, financial, hospitality, government, and logistics. Named reference projects and end-customers include Plymouth Regional Hospital, Tufts, MIT, Lonza, Medtronic, LL Bean, Whole Foods, Morgan Stanley, Liberty Mutual, UPS, USAF, National Grid, Johnson Controls, and Teledyne. The breadth of enterprise logos is the most visible signal of capability across technically demanding scopes (clean rooms, regulated environments, process ventilation).
Air Source generates revenue through project-based, competitive-bid contracts awarded by general contractors, mechanical contractors, and facility owners; there is no indication of recurring maintenance contracts, subscription revenue, or product licensing in the available data. Headcount is reported in the 11-50 range. No funding rounds, acquisitions, partnerships, awards, or patents are disclosed. The business model positions Air Source as a focused single-trade execution firm rather than a scaled platform or product business, and the competitive basis is technical execution, scheduling reliability, and trade-craft reputation rather than proprietary technology or data assets.
