Anchor Stone HVAC Duct Fabrication traces its roots back more than half a century — the company says its work continues the duct-manufacturing division of Air Purchases Inc., a Massachusetts HVAC company founded in 1969, since folded into Anchor Stone's Burlington shop. It describes itself as a precision custom ductwork fabricator for commercial and industrial clients — hospitals, schools, labs, and industrial facilities — across Massachusetts, with Boston named as part of its service area. Outside reviews are scarce: the one Google review on record calls the shop "a fantastic fabshop," but with just a single rating, there isn't much from customers yet to weigh beyond that. Anyone lining up a fabrication job with Anchor Stone would do well to ask about current lead times and recent project references directly, since little beyond the company's own history is available yet.
