We’re based in Yonkers and regularly on the road through Larchmont — usually within 20 minutes of your call if you’re in the 10538 ZIP code. Ryan Bell, our owner and lead technician, has been cleaning ductwork in coastal Westchester homes for 8 years, and he’s the one who shows up at your door, not a subcontractor you’ve never met. That matters in a village like Larchmont, where the housing stock is unlike anywhere else in the county.

Here’s what we’re talking about: Larchmont’s compact village core is overwhelmingly pre-WWII colonials, Tudors, and center-hall homes that were originally built with steam-radiator heat — no ductwork whatsoever. Central air and forced-air heat were retrofitted, often in the 1970s–1990s, routed through finished attics, knee walls, and closets in irregular configurations that create debris-trapping dead zones and moisture pockets unlike anything found in purpose-built suburban duct systems. Compounded by the village’s direct exposure to Long Island Sound’s salt air and harbor humidity, these retrofit duct runs are disproportionately prone to mold colonization and particulate accumulation. That’s not a generic claim. It’s the pattern we see on nearly every Larchmont job.

Our Air Duct Cleaning team uses Rotobrush rotary brush systems and Nikro HEPA vacuum extraction — the same equipment brands you’ll find in commercial remediation work — because these retrofit systems often need more than a surface cleaning.

Why Redwood Air Duct Cleaning Service Yonkers Is Larchmont’s Preferred Air Duct Cleaning Company

The owner is the technician. Ryan Bell personally performs every Larchmont service call. There’s no rotating crew, no dispatcher sending an unknown face to your home. When you book with us, you’re booking 8 years of hands-on ductwork experience and direct accountability for the outcome.

That accountability shows in our numbers: 1,005 households have trusted us, and they’ve rated the work an average of 4.9 stars. That’s one of the highest review volumes in the local air duct cleaning category — not a handful of handpicked testimonials, but a verified track record you can read for yourself.

Our response time to Larchmont is typically same-day or next-day. We know the village’s street layout, the parking constraints near the harbor, and the access challenges of homes on narrow lots with limited driveway space. We don’t waste your time figuring out where to park or how to reach a third-floor attic hatch in a 1925 center-hall colonial.

We’ve also developed specific protocols for Larchmont’s coastal retrofit ductwork. Because these systems were added decades after the homes were built, they often lack proper drainage slopes, insulation, or vapor barriers. We know where to look for the condensation points, the kinked flex runs, and the corroded seams that standard cleaning crews miss.

Our Air Duct Cleaning Services in Larchmont

Residential Duct Cleaning

Most Larchmont homes we service fall into two categories: the village-center pre-war houses with retrofit attic ductwork, and the newer construction closer to the Larchmont Manor Beach area. The older homes require careful handling — those 1970s–90s flex duct runs can be brittle, and the fiberglass-lined sheet metal common in that era releases fibers if agitated improperly. We adjust our Rotobrush speed and vacuum pressure based on what we find during our initial video inspection. A typical Larchmont residential cleaning runs $380–$620 for a single-zone system, $580–$780 for multi-zone homes with attic and basement runs.

Commercial Duct Cleaning

Larchmont’s commercial base is concentrated along Palmer Avenue and Boston Post Road — medical offices, retail spaces, and professional services in mixed-use buildings. These systems often share walls with residential units and require scheduled work that doesn’t disrupt neighboring businesses. We’ve cleaned ductwork for property managers in the Larchmont Gardens and Chatsworth areas, working early mornings or weekends to minimize downtime. Commercial pricing starts around $850 for small office suites and scales based on system complexity.

Supply Duct Cleaning

Supply ducts deliver conditioned air to your rooms, and in Larchmont’s retrofit systems, they’re often the most compromised. The supply runs from attic air handlers frequently pass through unconditioned spaces where salt-laden humidity corrodes seams and delaminates interior liners. We see this especially in homes near the Larchmont Yacht Club and along the waterfront blocks where prevailing winds carry Sound moisture directly into attic vents. Our supply duct service includes full brush contact cleaning plus seam inspection for corrosion or separation.

Return Duct Cleaning

Return ducts pull air back to the system for reconditioning, and they’re the primary collection point for household dust, pet dander, and particulate. In Larchmont’s older homes, return pathways were often improvised — panned floor joists, closet chases, or sheet-metal boxes squeezed into existing framing. These irregular geometries trap debris that standard cleaning misses. We use video inspection to map the actual return path before we start, then target our cleaning to the real configuration, not an assumed one.

Full System Cleaning

This is our most comprehensive service and the one we recommend for most Larchmont homes on their first visit. We clean every accessible component — supply trunks, branch lines, return pathways, registers, grilles, and the air handler cabinet — with our Rotobrush and Nikro HEPA system. For homes with the original retrofit ductwork still in place, we also include a structural assessment: we flag corroded seams, delaminated liners, and moisture damage that cleaning alone won’t fix. Full system cleaning in Larchmont runs $580–$920 depending on system size and accessibility.

Video Inspection

Every Larchmont job starts here. We feed a high-resolution camera through your ductwork before we touch a brush, documenting the actual condition — not guessing based on home age or symptoms. In Larchmont, this step is non-negotiable. We’ve opened systems that looked fine from the registers only to find collapsed flex duct, standing water in low spots, or active mold colonies hidden behind finished knee walls. The video gives you the same view we have, and it guides our cleaning protocol. Video inspection alone is $180–$240, but we waive it when you book a full cleaning.

Trusted Brands We Service in Larchmont

We maintain equipment from Rotobrush, Nikro, and Abatement Technologies — the same brands used in commercial restoration and remediation work. For filtration and air quality upgrades, we install Honeywell and Aprilaire systems sized to Larchmont’s specific humidity challenges. We don’t drop-ship parts from a warehouse three states away. We stock common fittings, flex duct, and antimicrobial treatments locally, so when your inspection reveals a corroded seam or delaminated liner that needs immediate attention, we’re not scheduling a second visit. That matters in a seasonal business where summer humidity spikes can turn a minor mold issue into a major air quality problem within weeks.

Common Air Duct Cleaning Problems We See in Larchmont Homes

• Salt-laden attic humidity corrodes galvanized sheet-metal seams and flex-duct wire helices within 5–7 years, far faster than inland systems. We open attic access panels and find rust bleeding through seams, or flex duct where the internal wire coil has corroded through, letting the duct collapse and restrict airflow. In a 1928 Tudor on Myrtle Boulevard, we found the original 1980s flex duct kinked inside a knee-wall cavity, with black mold coating the liner from years of coastal humidity. We replaced the damaged section with smooth galvanized pipe and applied an EPA-registered antimicrobial treatment, restoring airflow to the second-floor bedrooms.
• Retrofit duct runs through finished attics develop low spots where water vapor condenses, feeding mold colonies that standard cleaning often misses. These low points form where installers couldn’t maintain proper slope through irregular framing, and they’re invisible until you get a camera inside.
• Fiberglass-lined sheet metal, common in 1970s–80s retrofits, delaminates in Larchmont’s freeze-thaw cycles, releasing glass fibers into the air stream. The liner separates from the metal shell, creating a debris trap that also sheds particles every time the system cycles. We identify this condition with video inspection and recommend liner removal or duct replacement rather than cleaning alone.
• Improper attic ventilation combines with Sound moisture to create year-round humidity loads that overwhelm standard duct insulation. Vents blocked by decades of leaf debris or painted shut by previous owners trap moisture against duct surfaces, accelerating every failure mode above.
