Fast, Reliable Air Duct Cleaning Across Greenwich
Air duct cleaning in Greenwich, CT typically runs $450–$1,200 for residential systems, with backcountry estates reaching $1,800–$3,500 due to multiple air handlers and complex duct routing. Most jobs in 06830 and 06831 are completed same-day. Call (833) 754-6107 for a free estimate.
We’re familiar with every corner of Greenwich — from the coastal capes along Shore Road in Old Greenwich to the winding private drives of North Street in the backcountry. Richard Anderson — owner and lead technician — handles your job personally, bringing two decades of duct work to homes across 06830, 06831, and 06836. Whether you’re in a compact Riverside colonial with a tight basement clearance or a 15,000 sq ft estate with five separate systems, we’ve cleaned ductwork in your situation before. Our Air Duct Cleaning team arrives with Rotobrush video inspection gear and contractor-grade extraction equipment, ready to work around Greenwich’s parking constraints, security protocols, and the reality that many of these homes have never had their ducts properly mapped — let alone cleaned.
Why Landmark Air Duct Cleaning Service New York Is Greenwich’s Preferred Air Duct Cleaning Company
Richard Anderson has spent 20 years building a reputation one duct run at a time — not as a franchise operator, but as a specialist who shows up and does the work himself. That matters in Greenwich, where homeowners in backcountry estates have dealt with rotating contractors who don’t return calls and leave no documentation of what they touched. We’re the opposite: 548 customers, 4.9 stars — results you can verify before you book.
Our response time to Greenwich is typically same-day or next-morning, depending on whether you’re in 06830 near the Post Road or deeper into 06831 off Round Hill Road. We know the local conditions that shape the job — the coastal humidity pushing mold into crawl-space plenums in Riverside, the undocumented multi-system installations in backcountry homes, the original 1920s gravity systems still feeding ductwork in Old Greenwich colonials. This isn’t generalist HVAC work. Two decades of duct work, not generalist HVAC services.
From cleaning to repair to sanitizing — one call closes the loop on your air quality. We don’t hand you off to subcontractors or leave you coordinating multiple contractors for filters, sealing, and sanitizing.
Our Air Duct Cleaning Services in Greenwich
Residential Duct Cleaning
Greenwich’s housing stock demands more than a standard truck-mounted vacuum. In Old Greenwich and Riverside, we find original ductwork from the 1930s–1950s with no flex connections, narrow rectangular runs, and asbestos-wrap remnants that require careful handling. In backcountry estates, we’re often cleaning four or five separate systems that previous crews never located. Our process starts with a full video inspection so you see what we see — debris, mold, or blockages — before we commit to the scope. A typical residential duct cleaning in Greenwich runs $450–$950 for single-system homes, $1,200–$1,800 for properties with two to three zones.
Commercial Duct Cleaning
Greenwich Avenue retail spaces, medical offices near the hospital district, and professional buildings along Mason Street share a problem: occupied spaces with limited after-hours access and strict landlord requirements. We work around your schedule, bringing portable Nikro HEPA extraction units that don’t require rooftop access or parking a trailer on busy streets. Our commercial duct cleaning in Greenwich starts at $800 for small office suites and scales based on system count and access complexity.
Supply Duct Cleaning
Supply ducts deliver conditioned air to your living spaces — and in Greenwich, they’re often the first place we find mold from coastal humidity infiltration. Homes near Long Island Sound, especially in 06830 with crawl-space air handlers, show persistent mildew in supply plenums that standard filter changes never address. We use Abatement Technologies negative-air machines to isolate and extract contamination without spreading it to clean zones. Supply duct cleaning as a standalone service in Greenwich typically runs $350–$650.
Return Duct Cleaning
Return ducts pull air back to the handler — and they pull everything else with it. Pet hair from Greenwich’s active households, renovation dust from backcountry estate projects, and decades of accumulated debris in never-cleaned systems all collect here. Return ducts are also where we most often find blockages: collapsed flex, disconnected joints between additions, and in one case, a raccoon nest in a 1920s gravity return. Return duct cleaning in Greenwich averages $400–$750 for residential systems.
Full System Cleaning
This is our most requested service in Greenwich — and the one most often done incompletely by others. Full system cleaning means every air handler, every supply trunk and branch, every return path, and all accessible plenums. In backcountry estates, that means locating systems the homeowner didn’t know existed. We pressure-test after cleaning to verify we’ve actually reached everything. Full system cleaning in Greenwich ranges from $950 for compact single-system homes to $2,500–$3,500 for large multi-system estates.
Video Inspection
Our Rotobrush video inspection lets you see inside your ducts before we quote — no guesswork, no surprises. In Greenwich, this is especially valuable for pre-purchase inspections on historic homes and for estate managers who need documentation of system condition. Video inspection as a standalone service is $175, credited toward cleaning if you proceed.

Trusted Brands We Service in Greenwich
We work with Honeywell, Aprilaire, and Guardsman air quality systems — the same brands installed in many Greenwich homes over the past two decades. Richard Anderson stocks Aprilaire media filters and Honeywell electronic air cleaner components, so replacement after cleaning doesn’t mean waiting for parts. For backcountry estates with complex multi-zone setups, we specify Aprilaire whole-house dehumidifiers to combat the coastal humidity that keeps pushing mold into cleaned systems. Guardsman UV sanitizing units are another option we install for homeowners near the Sound who want ongoing microbial control between cleanings.
Common Air Duct Cleaning Problems We See in Greenwich Homes
- Undocumented multi-system estates. Technicians fail to locate or clean all separate air-handling systems in backcountry properties, leaving entire zones untouched — sometimes half the house never sees a brush. We map every system before we start.
- Mold in coastal crawl spaces. Greenwich’s southern edge along Long Island Sound creates persistently elevated coastal humidity that penetrates ductwork in homes with crawl spaces or basement air handlers, accelerating mold and mildew colonization inside supply and return plenums — a problem compounded in summer when unconditioned outdoor air is drawn in through aged duct seams.
- Unsealed addition connections. Duct connections between house additions are not pressure-tested or sealed, allowing unconditioned air and debris to re-enter cleaned systems. We find this constantly in Greenwich’s expanded colonials and estate wings added across different decades.
- Original ductwork in pre-war homes. Old Greenwich and Riverside homes built before 1940 often have uninsulated metal duct with asbestos-wrap remnants, narrow rectangular runs that don’t accommodate standard cleaning tools, and no flex connections for modern access. These require specialized equipment and technique that generalist crews don’t carry.

What moves you within these ranges? System count and accessibility are the big factors. A single air handler in a Riverside basement with good access hits the lower end.

Call (833) 754-6107 and we’ll schedule a free inspection with exact pricing before any work begins.

FAQs — Air Duct Cleaning in Greenwich
We start with a complete system survey using Rotobrush video inspection to locate and document every air handler, trunk, and branch — then clean and pressure-test each one. We recently serviced a 12,000 sq ft estate off North Street in the backcountry. The property had four separate air handlers—two from a 1950s addition, one original 1920s gravity system retrofitted, and a 1990s unit for a guest wing. Using our Rotobrush video inspection, we found a raccoon nest blocking the return duct of the oldest system and mold in the uninsulated crawlspace plenums. We fully cleaned all four systems, sealed leaks with mastic, and installed Aprilaire media filters to prevent future debris buildup. Call (833) 754-6107 to schedule a multi-system inspection — estimates are free.
Yes — often especially worth it, since original uninsulated metal duct in Old Greenwich has decades of accumulated debris and no modern sealing, meaning you’re breathing whatever’s in those walls. These systems require careful handling: we use smaller-diameter brushes and portable HEPA extraction to avoid damaging fragile joints or disturbing asbestos-wrap remnants. The improvement in airflow and particulate load is usually dramatic. Call (833) 754-6107 for a video inspection to assess your specific system’s condition.
We use portable Nikro and Rotobrush equipment that breaks down for tight access, and our hoses extend up to 150 feet so the main unit stays outside. Riverside’s coastal capes and ranch homes often have 18-inch crawl spaces with damp soil — we wear protective gear and use negative-air containment to prevent spreading mold spores during extraction. If the space is genuinely inaccessible, we’ll identify alternative access points through closets or floor registers. Call (833) 754-6107 to discuss access concerns for your Riverside home.
Yes — we regularly service townhomes in Old Greenwich and Riverside with shared walls and limited exterior access. Our portable equipment doesn’t require staging trailers or rooftop access, and we coordinate with building management for common-area access when needed. We also verify whether your ductwork is isolated or connected to neighboring units before cleaning, since some 1960s–1970s Greenwich multi-family construction shares return paths. Call (833) 754-6107 to confirm your building’s configuration.
We install Aprilaire media filters and Honeywell electronic air cleaners for ongoing particulate control, and specify Aprilaire whole-house dehumidifiers for homes battling persistent coastal humidity. For microbial concerns, Guardsman UV sanitizing units provide continuous treatment inside the plenum. These are the same brands we service and stock — no waiting for special orders. Call (833) 754-6107 to discuss which filtration upgrade fits your home’s conditions.
