Boston Air Systems

Boston Air Systems is a Braintree sheet metal shop that builds and installs ductwork, exhaust systems, and other HVAC infrastructure — but for commercial jobs, not private homes. The company describes itself as a commercial sheet metal fabrication and installation contractor serving the greater Boston area with HVAC ductwork, restaurant exhaust systems, and related metal work. By its own account, the business dates to 2005 and is still run by its founders, Jay Blazo and Barry Dwyer, having grown from five workers to around seventy. Its sheet metal crews are Local 17 union members, and its Massachusetts sheet metal/HVAC license, 229-SM-B, is active. What's missing is any real customer track record: public review activity amounts to a single 5-star Google rating, with no written reviews behind it. That single number isn't enough to say much about what it's actually like to work with them. For a homeowner, the bigger flag is scope — everything the company publishes points to commercial and institutional sheet metal work, not residential HVAC calls. Anyone considering them for a house should confirm directly that they take on residential jobs at all before requesting a quote.
