Why Greenwich Homeowners Choose Bellows Air Duct & Vent Co.
We’ve been called to homes on Lake Avenue where the same family has lived for forty years, and to weekend properties in the 06831 back-country where the owner flies in from Teterboro on Friday evening. In both cases, the homeowner wants the same thing: someone who shows up when they say, does what they promised, and doesn’t invent problems to sell additional services.
Bellows has built that reputation in Greenwich over twelve years, working in neighborhoods from Cos Cob to Old Greenwich to the estate sections north of the Merritt Parkway. Our technicians are background-checked and uniformed, and they arrive with professional-grade equipment from Nikro and Honeywell, the same brands serious HVAC contractors specify for their own jobs. Every cleaning includes camera inspection before and after, so you see what we see, not just take our word for it.
Our 90-Day Done Right Promise applies to every Greenwich job. If something isn’t right, we return at no charge. No paperwork to file, no manager to escalate, no argument. We’ve operated this way since 2012, and it’s why most of our Greenwich calls come from referrals and repeat customers rather than coupon sites.
Air Duct Cleaning Services We Offer in Greenwich
Air Duct Cleaning
We clean supply and return ductwork with Rotobrush and Nikro HEPA vacuum systems, removing accumulated dust, debris, and biofilm from the entire run, not just what you can reach from the register. Camera verification confirms the job before we pack up.

Dryer Vent Cleaning
Clogged dryer vents cause thousands of house fires annually, and Greenwich’s older homes on Putnam Avenue and Maple Avenue often have long, winding vent runs through finished walls that trap lint in ways newer construction doesn’t. We clean the full run from dryer to termination with rotary brushes and high-velocity air, then verify airflow with a manometer.

HVAC Cleaning
Evaporator coils, blower assemblies, and plenums collect the same debris as ducts, and in Greenwich’s humid summer conditions, that debris becomes a mold substrate. We clean the full air handling unit, not just the box around it.

Duct Repair & Sealing
Older Greenwich homes, especially the 1920s colonials and Tudors near downtown in 06830, often have ductwork that was retrofitted around original steam heating systems. The result is irregular runs, mixed-material plenums, and leaks at every joint. Our Duct Repair & Sealing in Greenwich uses mastic and mechanical fasteners, not tape that will fail in three years.
Air Quality & Sanitizing
For homes with allergy-sensitive residents or post-renovation dust concerns, our Greenwich Air Quality & Sanitizing service applies EPA-registered sanitizers through the duct system after cleaning. This is an add-on service, not a substitute for physical removal of debris, and we quote it separately so you know exactly what you’re paying for.
Neighborhoods We Serve in Greenwich
Our crews work throughout the 06830, 06831, and 06836 ZIP codes, with most Greenwich appointments available within one to two business days. These are the areas we know best:
- Back Country (06831) - Estate properties with multiple HVAC systems and extensive duct networks
- Downtown Greenwich (06830) - Older colonials, Tudors, and Victorians with retrofitted ductwork
- Cos Cob - Mixed housing stock from waterfront cottages to hillside homes
- Old Greenwich - Coastal properties with salt-air corrosion concerns on exterior duct components
- Riverside - Mid-century and newer homes with original flexible duct aging out
Why Greenwich’s Climate & Housing Affect Air Duct Cleaning
Greenwich sits at a geographic crossroads that creates unique stress on duct systems. The southern border on Long Island Sound keeps summer dew points elevated well into September, which means mold and biofilm grow on duct liner surfaces long after inland communities have dried out. In large back-country estates where guest wings or finished basements may go days without airflow, that moisture sits undisturbed, accelerating buildup that a standard every-three-years cleaning schedule won’t address.
The housing stock itself compounds the problem. Downtown homes in 06830 were built for steam or hot-water heat; forced-air ductwork came later, threaded through walls and attics never designed for it. Those retrofit runs are often under-insulated, and Greenwich’s cold, damp winters create condensation on cold metal in attic spaces. We’ve opened ceiling panels on Milbank Avenue and found rust streaks and mold staining that the homeowner never suspected because the register still blew warm air.
Then there’s the back-country pattern unique to 06831. Many of these estates function as weekend homes for professionals based in Manhattan. The HVAC system runs hard Friday through Sunday, then shuts down Monday morning. That stop-start cycle prevents the continuous airflow that would otherwise flush dust and moisture through the system. Dust settles, moisture condenses, and biofilm establishes itself in the idle days. A property with six or eight separate air handlers, each cycling independently, multiplies the effect. Crews that quote by the home rather than by the air handler routinely underbid these jobs and leave half the work undone. We quote by the system, so the scope matches the actual work.

FAQs About Air Duct Cleaning in Greenwich
Most Greenwich homeowners pay between $550 and $800 for a single-system home with up to 12 vents. Back-country estates in 06831 with multiple air handlers typically run $1,500 to $4,000 or more, quoted by the system so you know exactly what’s included. Call (844) 685-6342 for a free estimate - we’ll ask about your home’s size, age, and HVAC configuration and give you a firm number before we schedule.
Every three to five years is standard for most homes, but Greenwich’s coastal humidity and the weekend-residence cycling pattern common in 06831 can shorten that interval. Homes with allergy-sensitive residents, recent renovations, or visible mold should be evaluated annually. We include a camera inspection with every cleaning so you can see whether you’re due.
Yes, and we do it regularly. The 1920s-1950s homes near downtown Greenwich often have irregular duct runs and mixed-material plenums that require careful handling. Our technicians use adjustable brushes and protective shields to clean without damaging original plaster or fragile joints. Camera inspection is especially important in these homes to identify access points and potential problem areas before work starts.
Repair and sealing is usually the more economical choice for isolated leaks or disconnected joints, which we can often resolve for $400-$900 per system. Replacement becomes necessary when ductwork is extensively corroded, collapsed, or made of obsolete materials like asbestos-containing transite. We show you the camera footage and explain both options with firm pricing before you decide. Call (844) 685-6342 for an assessment - estimates are free.
We answer calls live 24 hours a day, and same-day or next-day appointments are often available for urgent situations like post-renovation dust, water intrusion, or suspected mold. For non-emergencies, most Greenwich appointments are scheduled within 48 hours. Call (844) 685-6342 and we’ll find the first opening that works for your schedule.
