Green Line Air Duct Cleaning

Green Line Air Duct Cleaning is a Quincy company that has built a striking record doing one thing very consistently: air duct and dryer vent cleaning, done with photo proof and a plain explanation of what it found. Reviewers keep circling back to specifics rather than adjectives — a bird's nest pulled out of a vent, a dryer hose connection rewired to code, mold spotted and cleaned at no extra charge. Google shows a 5★ average across 242 ratings, and the BBB gives the company an A+ as an accredited member. The written history backs that up with volume and consistency: 163 reviews on file since 2022, 31 of them in just the last six months, none negative. Specific accounts run deep — a 2026 review described ducts and coils at a house that likely hadn't been cleaned since it was built getting a full deep clean; a 2024 review recounted a technician correcting a dryer hose connection a big-box store had installed incorrectly, flagging it as a fire-hazard and airflow problem; another described a condo complex's dryer vents, packed with lint, cleaned across every unit. One reviewer said they found the company through NADCA, the national trade association for duct cleaners, specifically because they wanted certified professionals, and came away understanding the high ratings. Another described being told outright that their ductwork didn't need cleaning at all — the technician checked and found it in good shape rather than selling an unnecessary job. The one recurring note worth flagging isn't about the work itself — it's price: a couple of reviewers mentioned the quote felt a bit high going in, before deciding the thoroughness and documentation (before-and-after photos, sometimes video from inside the vents) justified it. For dryer vent or whole-house duct cleaning around the South Shore, Green Line reads as the safety-minded, document-everything option — ask for before-and-after photos as part of the job, since that's clearly their normal practice.
