Air duct cleaning is the process of removing accumulated dust, debris, allergens, mold spores, pet dander, and other contaminants from your home or building’s HVAC system — the supply ducts, return ducts, registers, grilles, and coils. When the system runs, anything sitting in those ducts circulates straight into the air you breathe. At Dependable Duct Cleaning, we use precision source-removal equipment and HEPA-filtered vacuums to clean the full system, not just the registers you can see. We’re family-owned, NADCA and OSHA-10 certified, and based in Southbury, serving Greenwich and the Fairfield County shoreline. When you call, you’re reaching a local family, not a national call center.
For homeowners, dirty ducts usually show up in small ways: a persistent musty odor, dust that resettles a day after you wipe it down, or allergy and asthma symptoms that get worse indoors. For commercial property owners, the effects are operational — higher HVAC energy costs, tenant or employee complaints, and indoor-air-quality concerns. Our residential and commercial duct cleaning follow the same careful, contained approach either way.
No pressure, no national hotline. Reach the family that actually does the work — serving Greenwich and the Fairfield County shoreline from our Southbury base.

Settlers from Massachusetts bought the land that is now Old Greenwich in 1640, and by 1730 the roughly fifty square miles of present-day Greenwich had been laid out. The railroad arrived in 1848, mills drew workers to Glenville and Byram, and by the end of the century New Yorkers were building along the shore in what became Belle Haven, Field Point Park, and Byram Shore, while families like the Rockefellers and Havemeyers assembled the backcountry estates. Houses from all three eras were heated for generations by fireplaces, coal, or oil before forced-air HVAC was retrofitted in, leaving non-standard duct runs where dust and debris settle for decades.
Cos Cob holds the antique core — colonial saltboxes and Georgians near the harbor and Strickland Road, anchored by the Bush-Holley House, built in stages from about 1728 and now a National Historic Landmark. Riverside and Old Greenwich grew as railroad suburbs and summer colonies from the late 1800s, so shingle-style cottages and center-hall colonials sit alongside newer rebuilds on the same streets, and the ductwork in the older ones has had a long time to collect dust, dander, and grit. We clean single-family homes throughout all three, and we handle commercial duct cleaning for the shops, offices, and restaurants along Greenwich Avenue and in the village centers.
Belle Haven was laid out as a planned waterfront association in the 1880s and 1890s, and north of the Merritt Parkway the backcountry runs to Georgian revival, Tudor, and French-inspired country houses on large wooded lots, where multi-zone systems and long duct runs give contaminants far more places to sit than a standard home does. Salt air along the shore, heavy tree pollen inland, summer humidity, and the long Connecticut heating season, when homes stay sealed from November into March, all feed the musty, dust-laden buildup we're called about most.

Get your free, in-person air duct cleaning estimate from a local, family-owned team serving Greenwich and the Fairfield County shoreline. We’ll look at the job before we quote it.
Every job follows the same five steps, and it starts with us actually coming to look — we never quote air duct cleaning over the phone. The full breakdown is below.
A technician visits your Greenwich property, inspects the system, and gives you an honest quote. We don't quote over the phone.
We check supply and return ducts, registers, coils, and accessible ductwork to map the full scope of the cleaning.
Professional-grade equipment dislodges and captures debris from the entire system — not just the openings.
High-powered HEPA-filtered vacuums ensure everything we loosen is removed, never just redistributed.
We show you what we found, what we did, and what to expect going forward — before we leave.
The only duct cleaning company that actually came and looked at the job before providing an estimate. In a business that has too many unethical players, I felt like I could trust Sal and his team. They were neat and thorough, and while the price was a little higher than others, I got full value for what I spent.
Sal explained everything in detail and answered all of my questions. The crew was on time, professional, and did a great job. My ducts had a musty smell and I was waking up stuffy every morning — that's completely gone now. I'll be hiring them again next year.
The best in the business. We've had them out twice in the past three years and they do an incredible job. Very professional, very personable, and the work speaks for itself. You would be missing out if you didn't hire this company.
They were polite, considerate — offered to remove their shoes — on time, efficient, and knowledgeable. No high-pressure sales, just great work from start to finish. I always refer them when someone asks.
Most Greenwich residential cleanings take 2 to 4 hours, depending on the size of the home and how complex the duct system is. Larger homes, multi-zone systems, and commercial properties take longer, and backcountry and Belle Haven properties with several zones routinely run well past that. We give you a realistic timeframe during your free in-home estimate before any work begins.
Yes. Cos Cob holds colonial saltboxes and Georgians near the harbor, some dating to the 1720s, and Old Greenwich and Riverside are full of shingle-style and center-hall houses from the railroad-suburb era. Every one of them had forced air added long after the framing went up, which leaves non-standard duct runs through original framing and old chimney chases. We clean them carefully and keep the work contained.
Yes. We're OSHA-10 certified and clean ducts for shops, restaurants, and offices along Greenwich Avenue and in the Cos Cob, Riverside, Old Greenwich, Byram, and Glenville village centers, as well as multi-family buildings throughout town. We schedule around your hours and provide post-service documentation.
Pricing depends on your property's size, duct configuration, and accessibility, so we don't quote over the phone. Greenwich properties vary more widely than most, from village cottages to houses with several independent zones, which is exactly why we look before we quote. We provide free on-site estimates, and you can read more on duct cleaning costs here.
Most Greenwich homes benefit from air duct cleaning every three to five years. Homes with pets, allergy or asthma sufferers, multi-zone systems, waterfront humidity, or recent renovations may need it more often, and high-occupancy commercial properties should consider annual cleaning.
