Whole-system duct and dryer vent check with before-and-after photos - you see exactly what came out of your vents
That "$99 whole-house special" is a bait ad - the real number appears once they are in your hallway, or the "clean" is a shop-vac at the register. We photograph the inside of your ducts before and after instead.
Fast, Reliable Air Duct Cleaning Across Greenwich
Air duct cleaning in Greenwich typically runs $450-$950 for most homes, with back-country estates on multi-zone systems ranging higher based on square footage and access complexity. Our crews dispatch from the Hartford office and carry Rotobrush, Nikro, and Abatement Technologies equipment on every truck serving Fairfield County. If you’re on a gravel lane off Round Hill or burning wood heat through the winter, your ducts reload faster than standard Fairfield County intervals suggest. Call us at (469) 972-3151 and we’ll give you a written price before any work begins.
We know Greenwich’s housing stock intimately. The stone estates north of the Merritt, the waterfront colonials in Old Greenwich, the post-war splits in Cos Cob and Riverside. Each neighborhood loads its duct systems differently. Salt air off Long Island Sound drives mold into return boots along Shore Road. Gravel road dust scours flex liner seams in the Back Country. Wood smoke ash settles in return trunks of homes that burn through the winter. Our technicians don’t guess at these conditions. They’ve worked them.
Every visit operates under The Kingswell Way: say the price, show up in the window we gave, leave the place cleaner, put the guarantee in writing, come back if it fails. That’s been our standard since 2004.
Why Kestrel Air Duct Cleaning Is Greenwich’s Preferred Air Duct Cleaning Company
Greenwich homeowners have long memories for contractors who changed the price at the door or no-showed the arrival window. We’ve built our reputation here by doing the opposite. Our written price reaches your hands before a single register cover comes off. Our 365-Day Done Right Promise goes on paper, not into a verbal assurance that evaporates after the invoice.
Our technicians are background-checked, uniformed, and trained on estate-grade systems. They carry professional-grade equipment, not shop vacs with extra hose. When we clean a duct system in Riverside or Old Greenwich, we use Rotobrush rotary brush agitation to dislodge debris at the duct wall, Nikro negative-pressure units to pull contaminants out of the system entirely, and Abatement Technologies HEPA filtration to keep loosened particles out of your living space during the work.
Calls to (469) 972-3151 are answered by a live person, any time of day. Not a queue. Not an automated system. A real conversation with someone who can schedule your visit, explain our process, and give you an honest sense of what your home will cost before we ever dispatch a truck.
Air Duct Cleaning Services in Greenwich
Air Duct Cleaning Services in Greenwich cover the complete source-removal cleaning of supply and return ductwork, register covers, and the air handler blower assembly. Most Greenwich homes fall in the $450-$750 range for a standard single-system cleaning, while back-country estates with multiple zones or complex access run $750-$1,400+. We clean what we can see and what we can’t, using camera inspection to verify the condition of interior duct surfaces before and after.
Residential Duct Cleaning
Our residential work spans the full range of Greenwich housing. A 2,500-square-foot colonial in Cos Cob needs a different approach than a 12,000-square-foot estate off North Street with four air handlers. We size the crew and equipment to the job, not the other way around. Single-system homes typically take 3-4 hours. Large estates may run two days with multiple technicians.

Commercial Duct Cleaning
Greenwich’s commercial inventory includes professional offices along Greenwich Avenue, retail spaces, and institutional buildings with packaged rooftop units. Commercial systems require scheduled downtime coordination and often involve access challenges above drop ceilings or in mechanical penthouses. We plan these cleanings around your operating hours and provide documentation for facility managers and property insurers.

HVAC Duct Cleaning in Greenwich
HVAC Duct Cleaning in Greenwich addresses the entire forced-air system, not just the visible registers. We clean supply trunks that push conditioned air to your rooms, return trunks that pull air back for reconditioning, and the blower motor and coil assembly where debris accumulation costs you efficiency. Standard single-system HVAC duct cleaning in Greenwich runs $500-$850; multi-zone estate systems with complex access range $900-$1,600+.
Full System Cleaning
A full system cleaning means every component that moves air. We remove and wash register covers, clean supply and return ductwork with rotary brush agitation under negative-air extraction, vacuum the blower cabinet and motor, and inspect the evaporator coil for debris loading that restricts airflow. In Greenwich’s older homes, we frequently find collapsed flex sections and deteriorated duct wrap that need flagging for repair before they become air leaks.
Video Inspection
Camera inspection lets us show you what we found. Before cleaning, we feed a lighted borescope through the duct run to document debris loading, mold growth, or structural damage like disconnected joints or crushed flex. After cleaning, we run the camera again so you can verify the results. In waterfront Greenwich homes where salt humidity drives mold, this documentation is particularly valuable for insurance and resale purposes.
Trusted Brands We Service in Greenwich
We clean duct systems connected to every major HVAC manufacturer, and we stock filtration products from Aprilaire, Guardsman, and Honeywell for Greenwich homeowners who want to maintain cleaner air between service visits. Aprilaire media air cleaners upgrade standard one-inch filters to four-inch pleated media that captures finer particles without restricting airflow. Guardsman UV-C systems install in the ductwork to suppress mold and bacterial growth, particularly valuable in Greenwich’s humid coastal zones. We size and quote these upgrades during your cleaning visit if your system is a candidate.
Common Air Duct Cleaning Problems We See in Greenwich Homes
- Coarse road dust scouring flex liner seams. Homes on unpaved lanes in the Back Country and mid-country load ducts with grit that behaves differently from fine household dust. The particles are larger, heavier, and more abrasive. They settle in low duct runs and accelerate wear at flex liner connections.
- Mold bloom in waterfront return boots. The salt-laden humidity of Old Greenwich, Riverside, and Cos Cob creates chronic moisture conditions in basement and crawl-space ductwork. We find mold concentrated in return-air boots along Shore Road and Sound Beach Avenue, where tidal humidity penetrates year-round.
- Asbestos-containing duct wrap on pre-1980 construction. Many Greenwich estates built between the 1920s and 1960s retain original duct insulation wrapped in materials that require certified abatement evaluation. We cannot legally disturb these materials without proper testing and, if present, licensed abatement coordination.
- Ash and creosote loading from wood heat. Back-country homes that burn wood stoves or fireplaces through the winter see accelerated debris accumulation in return trunks. The fine ash particulate bypasses standard filters and coats blower motors and coils, reducing efficiency and shortening equipment life.

FAQs About Air Duct Cleaning in Greenwich
Every 18 to 24 months, not the standard 3-to-5-year interval recommended for typical Fairfield County homes. The combination of coarse road dust and wood smoke ash reloads supply and return ducts faster than fine household debris alone. We set the next visit at 24 months for a Round Hill Road estate with twin wood stoves and a quarter-mile gravel drive, and that owner has stayed on that cycle since. Call (469) 972-3151 and we’ll evaluate your specific loading factors.
Yes, if the home retains original ductwork and pre-1980 construction. Many Greenwich estates built between the 1920s and 1960s have duct insulation wrapped with asbestos-containing materials. We cannot legally proceed with agitation or disturbance until certified testing confirms the wrap is asbestos-free, or until licensed abatement has been completed. We coordinate this evaluation as part of our pre-work assessment. The cost of testing is separate from cleaning and typically runs $400-$800 depending on sample count.
Outbuilding systems often have shorter, older duct runs with different diameter and material than the main house, and they may be served by a separate air handler with limited access. Our standard truck-mounted negative-air unit may be oversized for these smaller systems, and the duct loading pattern differs, especially if the outbuilding houses workshop equipment or vehicles that introduce additional particulate. We assess each building independently and may deploy a smaller portable unit for the secondary structure.
A two-day project with multiple technicians, one zone at a time, to ensure every register, trunk line, and blower motor receives proper source removal. We don’t book a single-visit cleaning on a 10,000-square-foot home and then run short on time. Each zone gets rotary brush agitation, negative-air extraction, HEPA filtration, and post-cleaning camera verification. The schedule is planned in advance with the homeowner, and the written price covers the complete scope.
Yes. Rotobrush and Nikro are the professional-grade systems we carry on every truck, and they’re compatible with all standard residential and light-commercial duct materials. Your HVAC service company maintains the mechanical equipment. We specialize in source-removal cleaning of the ductwork itself. The two services complement each other, and we coordinate with your HVAC contractor if they flag duct conditions during seasonal maintenance. Call (469) 972-3151 to schedule around your existing service relationship.
