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.

AfterAir Duct Cleaning Company in Greenwich, CT
Air duct cleaning in Greenwich costs between $425 and $1,250 for most homes, with backcountry estates running $1,800 and up depending on system size. What makes Greenwich different from neighboring towns is the housing stock itself: pre-war fieldstone estates, mid-century colonials, and new custom builds each present their own ductwork challenges. Morton’s Air Duct Cleaning has worked in enough Greenwich homes to know that a 12,000-square-foot backcountry estate and a 1950s Cos Cob colonial can’t be priced or cleaned the same way. Call (323) 918-4345 for a written quote before any work begins.
Why Greenwich Homes Are Different
Greenwich’s backcountry and mid-country estates, many spanning 8,000 to 20,000-plus square feet across multiple wings, run multi-zone HVAC systems with hundreds of linear feet of ductwork. These aren’t weekend-cleaner jobs; they require commercial-grade equipment rarely needed for standard Connecticut residential work. Because these homes turn over to high-net-worth buyers who commission full renovations, post-construction dust loaded with drywall compound and fiberglass particles routinely gets sealed into systems that look pristine from the outside. We’ve opened registers in newly renovated Greenwich homes and found an inch of white dust caked inside the boot.
The older stock brings its own complications. Pre-1940 fieldstone-and-timber homes often still have original galvanized duct sections, and some contain asbestos-insulated segments that require careful handling. Meanwhile, mid-century colonials in Riverside and Cos Cob frequently have flex-duct retrofits jammed into historic framing during past renovations, kinked and leaking in ways that pull unconditioned air into the system. Long Island Sound’s coastal influence keeps humidity elevated across Old Greenwich, Cos Cob, and Riverside year-round, which creates persistent conditions for mold amplification inside ductwork, especially where leaky return-air chases draw in coastal air from crawlspaces or basements.
Our Main Greenwich Services
Greenwich homeowners call us most often for two jobs: full air duct cleaning and dryer vent cleaning. Each has its own dedicated Greenwich page with pricing, process details, and what to expect.
Air Duct Cleaning in Greenwich
Full-system air duct cleaning in Greenwich means getting into every register, return, and trunk line, including secondary systems serving detached guest houses, pool houses, or converted carriage houses. Those auxiliary units are routinely skipped during annual HVAC service calls, and we frequently find they’ve gone a decade or more without any duct cleaning despite year-round occupancy. We use Rotobrush and Nikro negative-air equipment sized for large residential and light commercial systems, which matters when the house has 400 linear feet of trunk line. Read the full breakdown on our Air Duct Cleaning in Greenwich page.
Dryer Vent Cleaning in Greenwich
Dryer vent cleaning in Greenwich is a different job in older homes than newer ones. Pre-1970 construction often routed dryer exhaust through long, multi-elbow runs that exit through the roof or foundation rather than a direct wall vent, and those runs collect lint faster than modern short-path vents. A clogged or restricted dryer vent in a Greenwich laundry room adds heat and humidity to a house already fighting coastal moisture. We remove the lint, check the termination point, and leave the laundry area cleaner than we found it. Details and pricing are on our Dryer Vent Cleaning in Greenwich page.

What Greenwich Customers Say
"Ducts and dryer vent both. They put runners down the whole hall and wore booties. Spotless after, and they showed me photos of what came out. Worth every penny."
- Bonnie Vo"Spotless work. They laid drop cloths everywhere and I was honestly impressed there was zero mess at the end. Showed me the dirt they pulled out so I could see it was worth it."
- Shelby Dunham"New house, old dusty ducts. They were gentle in the house, laid down drop cloths, and double checked every register was sealed back up. Air smells fresh now."
