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-$1,200 for most homes, with backcountry estates ranging higher due to multi-zone systems and secondary HVAC units. Our crews are dispatched from our Hartford office and serve Greenwich daily, carrying commercial-grade Rotobrush and Nikro equipment sized for everything from Riverside colonials to mid-country compounds. Call (323) 918-4345 for a free written estimate before any work starts.
We’ve worked in Greenwich long enough to know the difference between a quick vacuum job and genuine source removal. Long Island Sound’s coastal humidity keeps ductwork damp through every season, especially in older homes near Cos Cob and Old Greenwich where leaky returns pull in unconditioned basement air. That moisture, combined with the town’s constant renovation cycle, creates conditions we don’t see in inland Connecticut markets. Our Air Duct Cleaning team treats every job to the Cedarwell Care Promise: shoe covers and drop cloths from the moment we arrive, quiet tool settings during nap hours, and a photo of your clean-up before we leave.
Why Morton’s Air Duct Cleaning Is Greenwich’s Preferred Air Duct Cleaning Company
Greenwich homeowners call us back because we treat their houses the way we’d want our own treated. Paul Adeyemi built Morton’s in 2005 around a simple idea: tell people exactly what you’ll do, exactly what it costs, and then do precisely that. No fogging upsells. No per-vent pricing tricks. One flat price per system, agreed in writing before we touch anything.
Our technicians are background-checked, uniformed, and trained to the Cedarwell C.A.R.E. values. They know to ask about pets before setting up equipment, to use drop cloths across your entry path, and to schedule around the rhythms of a family home. The 365-Day Done Right Promise backs every job. If something isn’t right, we make it right. Full stop.
We know Greenwich’s housing stock intimately. Original galvanized ductwork in pre-1940 backcountry estates. Asbestos-insulated runs in mid-century Riverside splits. Flex-duct retrofits jammed into historic framing during gut renovations. Each configuration demands different tooling and technique, and our crews arrive prepared for what they’ll actually find.
A live person answers our phone 24/7. Not a voicemail tree. Not a chatbot. When you’re coordinating around school pickup or a contractor’s schedule, that matters.
Commercial Air Duct Cleaning in Greenwich
Commercial Air Duct Cleaning in Greenwich addresses the larger-scale systems found in backcountry estates, converted carriage-house offices, and multi-wing residential compounds that functionally operate as commercial HVAC loads. These jobs require negative-pressure HEPA containment and agitation equipment that rental-grade vacuums cannot provide, especially when post-renovation debris like drywall compound and fiberglass particles has settled in duct runs spanning hundreds of linear feet. A typical commercial-grade residential system in Greenwich runs $1,200-$2,800 depending on zone count and contamination level.
Multi-Zone Estate Systems
Backcountry properties with 8,000 to 20,000-plus square feet often run five or more zones with separate air handlers. We seal each zone independently, maintaining negative pressure throughout, and clean blower motors and coils as part of the scope. Skipping these mechanical components leaves the source of redistribution intact.
Post-Renovation Recovery
New high-net-worth buyers frequently commission full renovations before moving in. Construction dust gets sealed into ductwork that looks pristine from the outside. We use video inspection to document pre-existing conditions, then extract debris with Rotobrush mechanical agitation paired with Nikro HEPA vacuum collection.
Air Duct Cleaning Services in Greenwich
Air Duct Cleaning Services in Greenwich cover the full range of residential systems found across the town’s distinct neighborhoods, from original ductwork in historic Backcountry estates to modern flex-duct installations in Cos Cob and Riverside renovations. A standard residential cleaning for a typical Greenwich colonial or contemporary runs $450-$850, with larger homes and multi-zone systems extending toward $1,200. Every job includes supply and return register cleaning, trunk line agitation, and a written price confirmed before work begins.
Video Inspection and Documentation
We feed a camera through your system before and after cleaning. You’ll see what we found, where it was, and what remains. In Greenwich’s humid coastal environment, this documentation is especially valuable for identifying microbial growth in flex-duct runs and return chases that homeowners cannot access themselves.

Source Removal vs. Surface Treatment
Our process removes settled debris and biofilm mechanically. We do not offer fogging “sanitiser” services as a standalone or add-on treatment. In coastal Greenwich conditions, fogging without source removal masks odor temporarily while leaving spore reservoirs intact. We consider that a disservice.

Trusted Brands We Service in Greenwich
We carry professional-grade equipment from Rotobrush, Nikro, Aprilaire, and Abatement Technologies on every Greenwich job, not entry-level rental gear. Rotobrush mechanical agitation brushes dislodge adhered debris from duct walls; Nikro HEPA vacuum systems maintain negative pressure and contain extracted material. For homes with Aprilaire or Honeywell whole-house air cleaners integrated into the duct system, we inspect and service those components as part of our scope when accessible. We stock common Guardsman protective materials and replacement filters for faster turnaround on follow-up visits. Our Hartford office maintains parts inventory for the brands we encounter most frequently in Fairfield County systems, so we’re not ordering components after we’ve already arrived at your home.
Common Air Duct Cleaning Problems We See in Greenwich Homes
- Microbial growth in coastal humidity zones. Long Island Sound’s influence keeps humidity elevated across Old Greenwich, Cos Cob, and Riverside year-round. Leaky return-air chases in older homes draw this unconditioned air into duct systems, creating persistent conditions for mold amplification inside flex-duct runs and trunk lines.
- Post-renovation debris sealed in “new” ductwork. Greenwich’s high turnover among luxury buyers means constant renovation. Drywall compound, fiberglass particles, and sawdust frequently enter systems during construction and remain after contractors leave, circulating through living spaces every time the fan runs.
- Neglected secondary HVAC systems. Backcountry estates almost always include separate units for guest houses, pool houses, and converted carriage houses. These auxiliary systems are routinely skipped during annual service calls and often go a decade or more without cleaning despite year-round occupancy.
- Improper prior cleaning stirring debris rather than removing it. Truck-mounted vacuums without adequate negative pressure or HEPA filtration are common in the Greenwich market. On large multi-zone systems, this approach redistributes settled post-renovation debris into living spaces instead of containing it for extraction.
Pricing for Air Duct Cleaning in Greenwich, CT
A typical residential duct cleaning in Greenwich runs $450-$850 for standard colonials and contemporary homes up to about 4,000 square feet. Larger homes with multi-zone systems, particularly in backcountry and mid-country estates, range $850-$1,200. Commercial-grade residential systems with extensive ductwork or significant post-renovation contamination can extend to $1,200-$2,800. These are whole-system prices, not per-vent teaser rates that balloon on the invoice.
What moves a job toward the higher end: zone count above four, secondary systems for guest houses or pool houses, visible microbial growth requiring extended agitation time, and significant post-construction debris loads. What doesn’t affect our price: the number of vents in a standard zone, or whether you mention a competitor’s coupon. We provide one flat price per system, in writing, before any work starts. Estimates are free. Call (323) 918-4345 to schedule.

FAQs About Air Duct Cleaning in Greenwich
Long Island Sound’s coastal influence keeps humidity consistently higher across Greenwich than in Hartford or Litchfield County, and older homes near the water often have leaky return chases that draw this damp basement or crawlspace air directly into duct systems. That combination creates persistent moisture conditions inside ductwork that accelerate microbial growth. We address this with source removal and chase sealing, not fogging. Call (323) 918-4345 for an inspection if you notice musty odors when your system runs.
Yes, and they’re frequently the most contaminated systems on the property. These secondary units are routinely skipped during annual HVAC service calls and often go ten years or more without cleaning despite year-round occupancy by guests, staff, or family members. We include auxiliary systems in our scope when requested, with separate written pricing for each unit. Call (323) 918-4345 to discuss a full-property assessment.
Construction debris enters duct systems through open registers and return grilles during renovation, and drywall compound dust, fiberglass particles, and sawdust frequently settle in runs that appear pristine from the outside. In Greenwich’s active luxury market, we’ve extracted significant debris from systems in homes where the owners had no idea contamination had occurred. Video inspection confirms what visual inspection cannot. Call (323) 918-4345 to schedule a pre- and post-cleaning camera review.
No. In Greenwich’s humid coastal environment, fogging without thorough source removal masks odor temporarily while leaving mold spores and biofilm reservoirs intact inside duct walls. The moisture from fogging can actually worsen microbial conditions. We do not offer fogging services because we consider them ineffective for the problems this climate creates. Our process uses mechanical agitation and negative-pressure HEPA extraction to remove source material completely. Call (323) 918-4345 for a written estimate on genuine source removal.
Every three to five years for primary residential systems under normal conditions, though homes with ongoing renovation activity, visible mold history, or significant pet dander loads may benefit from more frequent service. Secondary systems for guest houses and pool houses should be cleaned on the same schedule as primary systems, not left indefinitely. We provide maintenance recommendations specific to your property’s configuration after each job. Call (323) 918-4345 to establish a cleaning schedule that matches your system’s actual use.
