US Air Duct Services

US Air Duct Services works out of Newport Ave in Quincy, built around a fairly narrow promise: cleaning out home air duct systems for homeowners nearby. The one detailed review on file, though, isn't about ducts at all. A Quincy homeowner called in May 2026 after noticing water stains on a ceiling, and the company traced it to a chimney chase cover that had rusted through. The replacement took a couple of hours, everything was resealed and matched up, and a month later the leak hadn't come back — the customer called the price reasonable and said the crew cleaned up fully afterward. Past that single account and a passing mention in a Quincy 'top-rated contractors' roundup, there isn't much else to go on yet — one Google rating, one review. Worth asking directly: whether duct cleaning is still the core of the business, since the only job described so far was chimney work, not ductwork. For a one-off vent, duct, or chimney-adjacent repair in the Quincy area, they're worth a call — just confirm scope and get a written estimate before booking, since the public history here is still thin.
