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.

We’ve worked the waterfront blocks from Shore Road to Tomac Avenue long enough to know that Old Greenwich isn’t just another Greenwich neighborhood. The salt air off Long Island Sound, the 1920s-era housing stock with its patched-together duct systems, and the basement flooding patterns after coastal storms all change how we approach a job here. Our Air Duct Cleaning team doesn’t apply a suburban template to a shoreline home.
Why Kestrel Air Duct Cleaning Is Old Greenwich’s Preferred Air Duct Cleaning Company
We’ve built our reputation in Old Greenwich by showing up in the window we promised and leaving the price where we left it. Dale Whitmore and our local crews have handled enough post-storm calls off Sound Beach Avenue to know that documentation matters as much as the cleaning itself. When a homeowner needs photo evidence for an insurance adjuster, we deliver it.
Our technicians are background-checked, uniformed, and trained on the Kingswell Way: say the price before touching a vent, show up when you said you would, leave the place cleaner than you found it, put the guarantee in writing, and come back if it fails. The 365-Day Done Right Promise means exactly what it says. If our work falls short within a year, we return and make it right at no charge. No discretion, no hoops.
Calls are answered by a live person, day or night. Not a queue, not a callback tomorrow. A real conversation about what you’re seeing in your ducts and what we can do about it.
Commercial Air Duct Cleaning in Old Greenwich
Commercial Air Duct Cleaning in Old Greenwich covers retail spaces along Sound Beach Avenue, professional offices near the train station, and small commercial buildings throughout the 06870 zip code. These systems typically run larger than residential, with more complex zone controls and higher occupancy loads that push debris through ductwork faster. A commercial cleaning in Old Greenwich generally ranges from $1,200 to $3,500 depending on system size and accessibility, with post-construction or post-water-damage jobs at the higher end.
Retail and Restaurant Systems
Grease-laden return air and high customer turnover mean these ducts need more frequent attention. We use Nikro negative-pressure units to extract contaminants without shutting down your ventilation during business hours when possible.
Office and Mixed-Use Buildings
Older commercial structures near the Old Greenwich train station often have original galvanized ductwork retrofitted with modern flex runs. Our video inspection identifies where generations of modifications have created debris traps or airflow restrictions.
Air Duct Cleaning Services in Old Greenwich
Air Duct Cleaning Services in Old Greenwich start with understanding what kind of home we’re walking into. The Colonial Revivals and Cape Cods on Shore Road, Sound Beach Avenue, and Tomac Avenue were built between the 1920s and 1950s, many with central air added decades later. That means mixed-generation ductwork: original galvanized trunk lines spliced to 1970s or 1980s flex duct, sometimes with no unified layout and significant accumulated debris. A typical residential cleaning runs $450 to $850, with full-system jobs including video inspection and antimicrobial treatment at the higher end.
Supply and Return Duct Cleaning
Supply ducts push conditioned air to your rooms; returns pull it back. In Old Greenwich’s older homes, returns are often undersized or retrofitted into wall cavities that were never designed as ducts. We clean both sides of the loop because dirty returns recontaminate clean supplies immediately.
Video Inspection and Documentation
Our camera systems show you what’s inside your ducts before we start and after we finish. On waterfront homes, this documentation is often the difference between an approved and denied insurance claim after storm damage.

Trusted Brands We Service in Old Greenwich
We clean with Rotobrush rotary brush systems that physically dislodge debris from duct walls, Nikro negative-pressure units that pull loosened contaminants out of your home entirely, and Abatement Technologies HEPA filtration that keeps particles from resettling in your living space during the job. For homeowners who want to maintain cleaner air between service visits, we carry Honeywell, Aprilaire, and Guardsman filtration and indoor air quality products. Our Hartford office stocks common replacement parts and register boots for the galvanized systems prevalent in Old Greenwich’s older housing stock, so we’re not waiting on shipments when a rusted boot needs swapping.
Common Air Duct Cleaning Problems We See in Old Greenwich Homes
- Salt-air corrosion on galvanized trunk lines. The marine microclimate on Shore Road and Tomac Avenue accelerates rust scaling inside galvanized ductwork that crews in Cos Cob or Glenville rarely encounter. Camera inspection reveals pitting that surface cleaning misses entirely.
- Collapsed flex duct in crawlspaces and basements. Moisture degradation from Long Island Sound humidity causes flex runs to sag, kink, or separate at joints. We document whether the damage is repairable or requires replacement before any work begins.
- Mold colonization extended by coastal humidity. Old Greenwich’s elevated indoor relative humidity keeps mold viable well into autumn and again in spring. Cleaning without antimicrobial treatment here is temporary at best.
- Post-nor’easter water intrusion in basement mechanical rooms. Storm surge pushes water into low-lying areas near Greenwich Point, soaking return plenums and air handler bases. We distinguish cleanable sheet metal from waterlogged porous flex that must be replaced under NADCA guidelines.
Pricing for Air Duct Cleaning in Old Greenwich, CT
A typical residential air duct cleaning in Old Greenwich runs $450 to $850 for a complete supply-and-return system using brush agitation and negative-air extraction.

FAQs About Air Duct Cleaning in Old Greenwich
It depends on what got wet and for how long. Sheet-metal trunk lines and galvanized register boots can almost always be cleaned under NADCA standards if corrosion hasn’t perforated the metal. Porous flex duct, fiberglass-lined plenums, or waterlogged insulation must be replaced; they cannot be sanitized to safe levels after saturation. We document both categories with before-and-after photos so your insurer sees exactly why some components were cleaned and others replaced. Call (469) 972-3151 for a free post-storm inspection.
Old Greenwich’s direct exposure to Long Island Sound creates the highest salt-air concentration in town, accelerating galvanized steel corrosion that inland neighborhoods simply don’t experience. The same marine influence keeps indoor relative humidity elevated into October and again in April, extending the window when mold spores can establish inside ductwork by six to eight weeks compared to Cos Cob or Glenville. That’s why we recommend antimicrobial treatment on waterfront jobs where it would be optional inland.
Cleaning helps measurably when it’s done with the right equipment and documentation. Rotobrush agitation dislodges debris; Nikro negative pressure removes it; HEPA filtration prevents redistribution. For post-storm work, the value is in distinguishing salvageable metal duct from ruined porous materials and proving that distinction to your insurer. Cosmetic cleaning skips the inspection and documentation that make the difference in a real claim.
We map the splice points where original galvanized trunk lines connect to later flex runs, check for corrosion pitting inside the metal that surface rust hides, and identify kinked or collapsed flex in crawlspaces where moisture has degraded the structure. The goal is finding the weak links in a patched-together system before they fail completely. Video inspection shows you exactly what we found and where.
Yes, and we recommend it. Dryer vent cleaning is a separate service, but our technicians will inspect the accessible portions of your dryer exhaust run during an air duct cleaning visit and note any blockages, improper materials, or code issues. If cleaning is needed, we’ll quote it on the spot with the same upfront pricing standard. Many Old Greenwich homes have long vent runs through finished walls that accumulate lint despite regular trap cleaning.
The Old Greenwich Difference: When to Clean and When to Replace
Old Greenwich sits directly on Long Island Sound, making it the most salt-air-exposed corner of Greenwich. That marine microclimate accelerates galvanized ductwork corrosion and drives above-average interior humidity into HVAC systems year-round. Unlike inland Greenwich neighborhoods such as Cos Cob or Glenville, homes here face persistent coastal moisture infiltration that promotes mold and mildew colonization inside duct systems, making cleaning frequency and post-cleaning antimicrobial treatment a harder sell everywhere else but a genuine necessity here.
On a post-nor’easter call off Sound Beach Avenue near Greenwich Point, our tech pulled a flooded air handler and found standing water in the return plenum plus a collapsed flex run in the crawlspace. Camera inspection showed rust-scaled register boots and mold colonization on the galvanized trunk line that had been invisible from the registers. We documented the wet porous flex as non-salvageable and the sheet-metal trunk as cleanable under NADCA standards, then ran negative pressure source removal with HEPA filtration and applied antimicrobial treatment so the homeowner’s insurer had photo evidence for both the replace and the clean line items.
Three failure patterns keep showing up in Old Greenwich, and they’re all avoidable with the right approach. Some crews treat salt-air rust as cosmetic and skip camera inspection, missing corrosion pitting inside galvanized trunk lines on Shore Road and Tomac Avenue that only shows up two miles inland as a non-issue. Others dry the air handler after basement flooding but leave wet flex duct and return plenums in place, seeding mold that reappears within weeks and gets denied by the insurer for lack of documentation. And too often, cleaning is sold without antimicrobial treatment, ignoring that Old Greenwich’s marine humidity keeps the mold window open into autumn and spring. Here, that treatment isn’t an upsell. It’s part of doing the job right.
We’re not interested in selling you duct replacement you don’t need, and we’re not interested in cleaning duct that should be torn out. The Kingswell Way means documenting the difference, putting it in writing, and standing behind the call we make. If we’re wrong, the 365-Day Done Right Promise covers it. Dale Whitmore and our team have been applying that standard since 2004.
Call (469) 972-3151 for a free estimate. We’ll give you a written price before any work begins, show up in the window we promise, and leave you with documentation that holds up with your insurer and your own standards for your home.
