Why Landmark Air Duct Cleaning Service New York Is Larchmont’s Preferred Air Duct Cleaning Company
Richard Anderson — owner and lead technician — handles your job personally. That single fact changes everything about what you get. Two decades of duct work, not generalist HVAC services. When you book with us, the person who built this business is the one who shows up at your Larchmont door with a Rotobrush system and a video inspection camera.
Our reputation is verifiable: 548 customers, 4.9 stars — results you can verify before you book. Larchmont homeowners specifically mention our thoroughness with older systems and our willingness to explain what we find rather than push unnecessary upsells. We’re typically on-site in Larchmont within 24 hours of your call, sometimes same-day if you’re near Boston Post Road or Palmer Avenue.
We understand the village’s coastal position. Sitting directly on Long Island Sound, Larchmont experiences coastal humidity levels noticeably higher than inland Westchester towns; summer dewpoints and salt-air moisture push inside duct surfaces toward condensation, creating a recurring mold and microbial contamination problem that makes annual or biennial cleaning cycles more justifiable here than in drier upland communities like White Plains or Pleasantville. That isn’t generic copy — it’s why we carry Abatement Technologies HEPA containment and Nikro negative-air equipment on every Larchmont truck.
Our Air Duct Cleaning Services in Larchmont
Residential Duct Cleaning in Larchmont
Most Larchmont homes were built between the 1890s and 1930s — Colonials, Tudors, and Craftsman bungalows, many in the historic Larchmont Manor section near the water. Ductwork in these homes was added after the fact into structures built around cast-iron radiators, meaning technicians frequently encounter non-standard duct sizing, makeshift transitions, and insulation materials from multiple renovation eras. Our residential cleaning accounts for this: we inspect before we agitate, and we adjust our brush systems for the tight clearances and excessive bends common in retrofit runs. A typical residential duct cleaning in Larchmont runs $350–$600 depending on system size and accessibility.
Commercial Duct Cleaning in Larchmont
Larchmont’s commercial base — medical offices along Palmer Avenue, retail near the train station, and professional buildings on Boston Post Road — faces different pressures than residential. Higher occupancy, tighter schedules, and HVAC systems that run harder during humid summer months. We work after-hours and weekends to avoid disrupting your operation. Commercial jobs in Larchmont typically start around $800 and scale with square footage and system complexity.
Supply Duct Cleaning in Larchmont
Supply ducts push conditioned air into your rooms. In Larchmont’s retrofitted systems, these runs often travel through unconditioned wall cavities where coastal humidity condenses on metal surfaces. We clean supply trunks and branch lines with rotary brush systems sized to the actual duct diameter — critical when you’re dealing with non-standard sizing from a 1960s or 1970s retrofit. Supply-only cleaning runs $250–$400 in most Larchmont homes.
Return Duct Cleaning in Larchmont
Return ducts pull air back to your HVAC unit, and they’re the first place we look when Larchmont customers complain of persistent odors or heavy dust. Returns in older homes often use wall cavities or joist channels rather than dedicated ductwork, making them harder to clean thoroughly without specialized tools. Our Nikro portable vacuums and compressed-air whips reach these irregular spaces. Return duct cleaning in Larchmont typically adds $150–$250 to a full system job, or $200–$350 as a standalone service.
Full System Cleaning
From cleaning to repair to sanitizing — one call closes the loop on your air quality. Our full system service covers supply trunks, branch lines, return pathways, and the air handler itself. For Larchmont’s challenging retrofit systems, this is usually the right starting point. Full system cleaning runs $500–$750 for most village homes, with larger Manor estates toward the higher end.
Video Inspection
We recently cleaned a 1920s Tudor in Larchmont Manor where 1970s flex-duct extensions had never been touched. Our Rotobrush pulled out fibrous debris from deteriorating duct liner and salt-moisture-driven mold colonies — a combination we rarely see in newer inland suburbs. Video inspection would have revealed that condition before we started. Our camera systems navigate the tight bends of Larchmont retrofits, giving you visual proof of what you’re breathing. Inspections run $150–$250 and are waived if you proceed with cleaning.

Trusted Brands We Service in Larchmont
We run Rotobrush brush systems and Nikro vacuum rigs on every job — the same equipment brands used by industrial and commercial contractors, brought into your Larchmont home. For customers with integrated air quality equipment, we service and source parts for Honeywell electronic air cleaners and Aprilaire media filters. We don’t have to order from a warehouse three states away; our New York-based supply chain means faster turnaround when your Larchmont system needs a component replacement alongside cleaning.
Common Air Duct Cleaning Problems We See in Larchmont Homes
- Retrofit duct runs with excessive bends and tight clearances trap debris faster than purpose-built systems. When Larchmont’s pre-war homes were converted from radiator heat to forced air, contractors shoehorned ducts through wall cavities never designed for them. Every elbow and restriction becomes a collection point for dust and debris that standard residential equipment can’t always reach.
- Condensation from coastal humidity leads to recurring mold and biofilm that standard cleaning may miss without video inspection. Larchmont’s direct exposure to Long Island Sound delivers persistent salt-laden coastal humidity that accelerates mold and biofilm growth inside retrofit ductwork, a condition almost never encountered in inland Westchester towns like White Plains or Pleasantville. Surface cleaning without verification often leaves active colonies behind.
- Older flex-duct from 1970s–80s retrofits harbors deteriorating liner fibers and salt-driven mold, requiring specialized extraction methods. In Larchmont Manor waterfront homes, technicians regularly find that older flex-duct extensions added during 1970s–80s central-air retrofits have never been cleaned and harbor both fibrous debris from deteriorating duct liner and salt-moisture-driven mold colonies — a combination almost never encountered in the same job in a newer inland suburb. Our Rotobrush systems with HEPA containment handle this safely.
- Multiple renovation eras create incompatible materials and connections. A Larchmont home might have original galvanized duct from a 1950s retrofit, joined to flex-duct from the 1980s, with modern foil tape repairs from a 2010s HVAC service call. Each interface is a potential leak point and contamination source. We identify and document these during cleaning so you know what you’re working with.

FAQs — Air Duct Cleaning in Larchmont
Retrofit duct runs feature excessive bends and tight clearances that trap debris far faster than purpose-built systems, while Larchmont’s coastal humidity accelerates mold growth inside those same ducts. We recommend every 2–3 years for most Larchmont homes, versus 3–5 years for newer construction in drier climates. Call (833) 754-6107 to schedule — estimates are free.
The most common problem is deteriorating flex-duct liner combined with salt-moisture-driven mold colonies in extensions added during 1970s–80s central-air retrofits. Our field experience shows this combination almost never occurs in newer inland suburbs. Video inspection identifies whether cleaning or replacement is the right call. Call (833) 754-6107 for an exact quote — estimates are free.
Yes — video inspection reveals liner deterioration, mold penetration depth, and structural integrity of flex-duct walls that external observation cannot. In Larchmont’s humid coastal environment, we often find surface mold that cleans easily alongside deeper biofilm that signals replacement is the smarter investment. Our $150–$250 inspection is waived if you proceed with either service. Call (833) 754-6107 to book.
Yes — we size our Rotobrush systems to the actual duct diameter and use Nikro portable vacuums with flexible hose configurations built for restricted spaces. Twenty years of working in New York’s older housing stock means we’ve developed techniques for the non-standard sizing and awkward access points common in Larchmont homes. Call (833) 754-6107 for an exact quote — estimates are free.
Larchmont’s direct exposure to Long Island Sound delivers persistent salt-laden coastal humidity that pushes duct surface temperatures below dewpoint more frequently and for longer periods than in drier inland communities. That condensation feeds mold and biofilm growth that standard dry-climate cleaning protocols don’t address. We carry Abatement Technologies HEPA containment specifically for these conditions. Call (833) 754-6107 for an exact quote — estimates are free.
