USA Air Duct And Chimney Services

USA Air Duct And Chimney Services works out of a Massachusetts Ave address in Cambridge, doing both ends of what keeps a house's air moving safely: chimney sweeps, repairs and cap installs on one side, and duct and vent cleaning on the other. Its Google page carries 4.8★ from 20 ratings, and every review on file dates to the past year. The chimney side shows up in the most specific detail. One homeowner who'd just bought an older house had a cracked crown and loose bricks rebuilt, with the old brick matched over a three-day job; another had a flue cleaned and a smoke test run, with photos of the creosote buildup shown before and after. Techs named in reviews — Justin removing a bird's nest from the flue and capping it, Gabe finding and adjusting a loose damper, Aaron diagnosing a bad draft behind a smoky fireplace — each get credited with explaining what they found and fixing it on the spot. On the duct side, customers describe dryer-vent cleanings that cut drying time from three cycles to one, and full duct and register cleanings with the air handler checked and pricing called transparent. One review even describes a same-visit AC contactor repair. A recurring note across reviews is that the crew works clean — protecting floors, leaving little to no dust or mess — with pricing described as fair. The one sour note isn't about the work at all: a January 2026 review complained the building has no visible entrance or sign, making the office hard to find in person. For chimney or duct work in Cambridge, this is a company with a specific, consistent track record — just call ahead for directions rather than expecting to spot a storefront.
