Green Line Air Duct Cleaning

Two technicians pulled a bird's nest out of a dryer duct in May 2026, along with enough lint to block the vent, and then swapped out a dryer connector that wasn't up to code. That visit is Green Line in miniature: they come for the vent, and they tell you what else is back there. Green Line Air Duct Cleaning works out of Quincy, covering Boston and the towns around it, Dedham, Springfield and out to Cape Cod, and the company says it also works in Rhode Island and New Hampshire. Air ducts and dryer vents are the entire business — it describes a four-stage HEPA filtration setup plus a sanitizing and odour-killing step. The Better Business Bureau accredits the company and grades it A+. One customer in May 2026 said she went looking for certified professionals and found Green Line through NADCA. Across 242 Google ratings the average is 5 stars, and customers are strikingly consistent about what a visit looks like: on time, floors protected or shoes off at the door, and before-and-after photographs handed over at the end. A March 2026 customer said the difference in those photos was hard to believe. A January 2026 customer had a whole house's ducts cleaned that probably hadn't been touched since it was built, plus the coils and the dryer vent. Another in June 2026 had seven years of HVAC ducts done across multiple floors and returns, and a startling amount of lint taken out of the dryer line. The crews teach while they work. A customer in May 2026 was shown how to change the filter to keep the ducts clean between visits; a March 2026 customer was told the exterior screen on his dryer vent traps lint and chokes airflow; a 2024 customer had a badly installed indoor dryer hose connection explained and corrected on the spot. In October 2025 a household had mold found during the job and cleaned up at no extra charge. Buildings get the same treatment as houses. Two technicians, Michael and James, cleaned every dryer vent in a condo complex in November 2025 and left the laundry rooms spotless; an apartment complex was done that same month; and in 2024 a building owner described three to four inches of build-up inside the HVAC system before the crew got to it. One customer uses them both commercially and at home. The one thing worth pinning down is the price. A May 2026 customer who called for a dryer vent cleaning found the sticker price jarring, though she still rated the visit five stars and reckoned regular maintenance pays for itself. Others describe the price as reasonable or fair, so settle the number for the floors, returns and vents you actually want done before the truck arrives. If your ducts haven't been touched in years, or the dryer needs three cycles to finish a load, this is a shop that does nothing else, photographs what it finds and explains the rest. Ask what the quote covers — customers routinely have the dryer vent done in the same visit as the HVAC ducts.
