Boston Air Systems

Boston Air Systems is a Braintree commercial sheet metal contractor rather than a residential service company — its own site describes fabricating and installing HVAC ductwork, restaurant exhaust systems, and related sheet metal work for the greater Boston area. The company says it was founded in 2005, is family-owned by Jay Blazo and Barry Dwyer, and has grown from 5 to 70 sheet metal workers, with technicians affiliated with the Local 17 sheet metal workers union. Its Massachusetts sheet-metal contractor license (229-SM-B) is registry-verified as active. Beyond that, there isn't much of a public track record to draw on — Google shows a single 5-star rating with no written review attached, and there's no customer account describing an actual job. Anyone considering them for a commercial or institutional project should ask for references from comparable work directly.
