Fast, Reliable Air Duct Cleaning Across Greenwich
Air duct cleaning in Greenwich typically runs $350-$850 for standard residential systems and $1,800-$4,500 for large back-country estates with multiple air handlers. Most jobs are completed in a single visit, with our Air Duct Cleaning in Greenwich team usually on-site within the same day you call. We’ve been driving these roads since 1984 - from the winding lanes of 06831 to the colonial blocks near Putnam Avenue in 06830 - and we know the difference between a straightforward clean and a job that demands patience and the right equipment.
Greenwich’s housing stock doesn’t forgive guesswork. A crew that treats a six-handler estate like a suburban ranch house will either underbid and rush, or show up unprepared. That’s not how we work. We quote by the air handler, inspect every run with a camera before we start, and show you exactly what we found when we’re done. Call (844) 685-6342 for a free estimate - we’ll be there when we say.
Why Bellows Air Duct & Vent Co. Is Greenwich’s Preferred Air Duct Cleaning Company
We’ve built our reputation in Fairfield County the old way: by doing what we promised and standing behind it. Our 90-Day Done Right Promise means if something’s not right, we return at no charge - no paperwork, no arguing. It’s stamped on every job, and it’s why homeowners in Cos Cob and Riverside call us back when their kids buy houses of their own.
Calls to our office are answered by a live person, 24 hours a day. Not a voicemail tree, not an app. When you’re staring at a water stain around a ceiling vent in a back-country guest wing at 9 p.m. on Sunday, you talk to someone who can dispatch a technician.
Our crews are background-checked and uniformed, every time. They arrive with Rotobrush and Abatement Technologies equipment - the same brands serious HVAC contractors specify - and they know Greenwich’s roads well enough to find a driveway off John Street or Clapboard Ridge Road without GPS gymnastics. Most jobs finish in one visit because we diagnosed correctly over the phone.
We’re not the cheapest name in the phone book, and we don’t try to be. We’re the company you call when you’ve already been burned by a low-bid operator who quoted $199 and left your system half-cleaned.
Our Air Duct Cleaning Services in Greenwich
Residential Duct Cleaning
From the compact colonials near Greenwich Avenue to the sprawling estates off Round Hill Road, our residential cleaning adapts to the house in front of us. Downtown homes in 06830 often have ductwork retrofitted around original steam or hot-water systems - irregular runs, mixed materials, access panels where you wouldn’t expect them. We map each branch before we brush or vacuum, and we camera-inspect every connection. A typical residential duct cleaning in Greenwich runs $350-$650 for single-system homes, $850-$1,400 for properties with two to three handlers.
Commercial Duct Cleaning
Greenwich’s commercial base runs from boutique professional offices on Mason Street to municipal buildings and small retail. We work around business hours, contain our equipment to minimize disruption, and provide before-and-after video documentation for facilities managers. Commercial pricing starts around $800 for small office suites and scales with system complexity and access requirements.
Supply Duct Cleaning
Supply lines push conditioned air to your rooms, and in Greenwich’s climate they’re where we most often find mold and biofilm. The persistent summer dew points along Long Island Sound - often 65°F or higher through June and September - create condensation on duct liner surfaces that static pressure alone won’t dry. We brush and vacuum supply trunks and branches, then verify cleanliness with camera inspection. Supply-only cleaning typically runs $250-$450 as a standalone service.
Return Duct Cleaning
Return ducts pull air back to the handler, and in older Greenwich homes they’re frequently the dirtiest part of the system - especially where original construction left returns as unlined wall or floor cavities. We seal and vacuum these runs with negative-air machines from Nikro, capturing debris rather than redistributing it. Return cleaning is usually bundled with full-system service but can be quoted separately.
Full System Cleaning
This is what most Greenwich homes actually need. We clean supply and return ductwork, registers, grilles, the air handler cabinet, and the evaporator coil - the component where Long Island Sound humidity does its worst damage. Full system cleaning for a standard single-handler home in Greenwich runs $550-$850. For back-country estates with six to eight air handlers, we quote by the handler; a full-property clean typically runs $1,800-$4,500 and may extend across two days.
Video Inspection
Every job starts and ends with a camera. We run a lighted borescope through your ductwork before we clean, so you see what we’re dealing with, and again after, so you see what changed. For downtown Tudors and Victorians with retrofitted ductwork, this step isn’t optional - it’s how we avoid damaging legacy insulation or disturbing asbestos-wrapped sections. Video documentation is included with every service and can be provided to insurers or renovation contractors on request.

Trusted Brands We Service in Greenwich
We specify professional-grade equipment from Rotobrush, Abatement Technologies, and Aprilaire - brands that HVAC contractors choose for their own jobs, not consumer-grade machines sold at big-box stores. For repairs and component replacements, we stock common parts for faster turnaround, and we source specialty items through our supply network rather than making you wait. When we recommend a product, it’s because we’ve installed it, serviced it, and know how it holds up in Fairfield County’s humidity.
Common Air Duct Cleaning Problems We See in Greenwich Homes
- Biofilm buildup in back-country estates from intermittent use. Many 06831 properties serve as weekend residences for NYC-based professionals. Systems cycle hard Friday through Sunday, then sit idle all week. Without continuous airflow, moisture settles on duct liners and evaporator coils, accelerating mold and biofilm growth that standard cleaning schedules miss.
- Underbid multiproperty jobs from crews quoting per home instead of per air handler. A single back-country estate can have six to eight separate air handlers. Local crews that don’t adjust their pricing model routinely underbid, then rush through or skip handlers entirely. We quote by the air handler so the scope is clear before we arrive.
- Condensation damage in uninsulated attic runs. Cold, damp Greenwich winters create condensation in attic ductwork common in older downtown housing stock. Water stains, rusted connections, and collapsed flexible duct sections are frequent findings in 06830 homes built between the 1920s and 1950s.
- Legacy mixed-material plenums in retrofitted downtown homes. Forced-air systems added to original steam or hot-water homes often splice galvanized sheet metal into asbestos-wrapped sections. Without careful video inspection and manual brushing, aggressive cleaning disturbs materials that should stay intact. Last fall, we serviced a 1920s Tudor off North Street in 06830 where exactly this situation required mapping each irregular run before we could clean safely - finished in under three hours, but only because we looked first.

FAQs - Air Duct Cleaning in Greenwich
You’ll likely need cleaning more often than inland Connecticut homes. Greenwich’s southern border on Long Island Sound keeps dew points elevated through late spring and early fall, creating persistent condensation on duct liner surfaces and evaporator coils - especially in secondary zones like guest wings and finished basements that see intermittent airflow. Most Fairfield County HVAC contractors recommend annual inspection and cleaning every 18-24 months rather than the standard 3-5 year interval. Call (844) 685-6342 to schedule - estimates are free.
You may have partial ductwork from a mid-century retrofit, or you may have none at all. Many 06830 homes converted from steam or hot-water to forced-air during the 1960s-1980s, adding ductwork around original radiator lines - often creating irregular, hard-to-access runs. We can verify what you have with a quick video inspection, usually completed in under an hour. Call (844) 685-6342 and we’ll tell you exactly what’s in your walls before quoting any work.
Your property likely has six to eight separate air handlers, each requiring individual access, brushing, and vacuuming. A Stamford colonial with one system is a two-hour job. A Greenwich back-country estate with multiple handlers, zone dampers, and extended duct runs is a fundamentally different scope. We quote by the air handler so you know the time and cost before we arrive - not when we’re halfway through handler three and the crew is already behind schedule. Call (844) 685-6342 for a property-specific estimate.
It usually helps significantly, but the source matters. Musty odors in intermittently used zones typically come from biofilm on evaporator coils or standing moisture in low-velocity duct runs - both common in Greenwich’s humid climate. Our full system cleaning addresses the ductwork and coil, and we camera-inspect to confirm we’ve reached the affected branches. If the smell persists, we may recommend a sanitizing treatment or HVAC contractor evaluation for drainage issues. Call (844) 685-6342 - we’ll diagnose the source before quoting.
Yes, we include before-and-after video with every job and can format documentation specifically for insurance or contractor records. In Greenwich’s active renovation market - especially estate properties adding guest wings or finishing basements - insurers and general contractors increasingly require verified duct condition reports before and after construction. Our camera records are date-stamped and narrated, suitable for claims or dispute resolution. Call (844) 685-6342 to arrange inspection and documentation.
