Fast, Reliable Air Duct Cleaning Across Nyack
Air duct cleaning in Nyack typically runs $280–$580 for a full residential system, with most jobs completed in a single morning or afternoon. We serve the 10960 ZIP and surrounding hillside neighborhoods with same-day scheduling when you call early, and Richard Anderson — owner and lead technician — handles every job personally. If you’re catching a musty note in your Victorian on South Franklin Street or noticing your allergy symptoms spike every time the heat kicks on in your Depew Avenue Colonial, you’re not imagining it. Nyack’s river-town humidity and retrofitted ductwork create problems standard crews miss.
We’ve been driving across the Tappan Zee Bridge and up the Palisades for two decades, and we know the difference between a tract-home system and the irregular duct runs hiding in Nyack’s closet cavities and knee-walls. Our Air Duct Cleaning team brings Rotobrush and Nikro equipment built for commercial jobs into your home — because Nyack’s old houses demand more than a shop-vac and a brush.
Why Landmark Air Duct Cleaning Service New York Is Nyack’s Preferred Air Duct Cleaning Company
Richard Anderson — owner and lead technician — handles your job personally. Not a franchise dispatcher, not a subcontractor you’ve never met. Two decades of duct work, not generalist HVAC services. That matters in Nyack, where a crew trained on suburban ranch homes can walk right past the actual problem in your 1890s Queen Anne.
Our numbers are public and verified: 548 customers, 4.9 stars — results you can verify before you book. Nyack homeowners specifically mention our thoroughness with older systems in review after review. They appreciate that we don’t treat their retrofitted ducts like an afterthought.
We schedule Nyack calls with buffer built in. These houses take longer. Rushing through a Victorian with flex-duct threaded through three closets and a knee-wall cavity doesn’t serve anyone. We arrive when we say we will, and we stay until the job’s done right.
From cleaning to repair to sanitizing — one call closes the loop on your air quality. No second contractor needed.
Our Air Duct Cleaning Services in Nyack
Residential Duct Cleaning
Nyack’s housing stock is unlike anywhere else in Rockland County. The village is dominated by late-1800s to early-1900s Queen Anne, Italianate, and Colonial Revival homes, most of which started life with radiator heat and had forced-air HVAC retrofitted in the 1960s–80s. Those retrofit ducts are frequently routed through closets, knee-wall cavities, and under staircases — unconventional runs with more seams, more debris traps, and far more cleaning complexity than a tract-home system. Our residential service maps every run before we start, so we’re not guessing where your supply lines actually go.
Commercial Duct Cleaning
Commercial properties along Main Street and near the waterfront face their own challenges. Mixed-use buildings with restaurant exhaust neighbors, older shared HVAC infrastructure, and the same Hudson River humidity that affects homes. We clean commercial systems with the same Rotobrush and Abatement Technologies equipment we use on industrial jobs — no downgraded service for smaller commercial spaces. If you’re managing a property on Broadway or Highland Avenue, we’ll coordinate around your tenants’ hours.
Supply Duct Cleaning
Supply ducts push conditioned air into your rooms. In Nyack’s retrofitted systems, these lines often travel through unconditioned spaces — exterior walls, attic kneewalls, crawlspaces beneath porches — picking up moisture and debris along the way. We isolate each supply branch and clean it under negative pressure so nothing blows back into your living space. This is where our video inspection pays off: we can show you exactly what the inside of that closet run looks like before and after.
Return Duct Cleaning
Return ducts pull air back to your HVAC unit for reconditioning. They’re your system’s lungs, and in older Nyack homes they’re often oversized, poorly sealed, or shared between floors in ways modern codes wouldn’t allow. Return lines are also where we most commonly find the heaviest buildup — decades of skin cells, pet dander, cooking residue, and river-valley pollen cycling through. We clean returns with dedicated agitation tools, not just suction, because packed debris in a 1970s metal return doesn’t release easily.
Full System Cleaning
This is what most Nyack homes actually need. Not just the visible vents, but the complete network: supply trunks, return trunks, branch lines, boots, and the air handler cabinet itself. Full system cleaning is our most common request in the 10960 ZIP, and for good reason — partial cleaning on a retrofitted Victorian just relocates the problem. We include video inspection before and after, so you see the complete picture.
Video Inspection
Before we touch a tool, we run a camera. Nyack’s irregular ductwork makes this non-negotiable. We’ve found collapsed flex-duct, disconnected boots, and active mold colonies that a surface inspection would never reveal. After cleaning, we run the camera again. You see what we see. No guesswork.

Trusted Brands We Service in Nyack
We work with and service Honeywell, Aprilaire, and Guardsman air quality systems — brands we encounter regularly in Nyack’s higher-end renovations and historic home updates. Our equipment comes from Rotobrush, Nikro, and Abatement Technologies, the same names you’ll find on commercial and industrial job sites. We don’t carry consumer-grade tools, and we don’t improvise. When your Nyack home needs a specific filter housing, UV light replacement, or humidifier pad for an Aprilaire unit, we stock common parts and can source specialty items without the multi-week wait you’d get from a generalist.
Common Air Duct Cleaning Problems We See in Nyack Homes
- Mold in unsealed flex-duct from the 1970s. On a recent job on South Franklin Street, we found a 1970s flex-duct run in a crawlspace that had never been sealed, hosting visible mold colonies that the homeowner thought was ‘river air.’ We cleaned the ducts with Rotobrush equipment, applied antimicrobial treatment, and sealed the vapor barrier to prevent recurrence. The Hudson River directly borders Nyack, and the surrounding valley geography traps fog and moisture, keeping relative humidity noticeably higher than communities just a few miles inland in Rockland County.
- Debris packed in knee-wall and closet cavities. Standard cleaning methods blow right past these irregular runs. Our Nikro equipment with extended reach tools and camera guidance finds what others miss. That debris isn’t just dust — it’s construction residue from decades ago, pet hair, and organic material that feeds mold growth.
- Loose joints in retrofitted ductwork allowing recontamination. Those 1960s–80s retrofits used tape and sealants that degrade. We find disconnected boots and gaping seams constantly. Cleaning without sealing is temporary. We identify these failures during video inspection and can repair or seal as part of the service.
- Homeowners blaming ‘river air’ for persistent musty odors. Technicians working Nyack’s hillside Victorian streets regularly find that homeowners blame a persistent musty smell on ‘river air’ coming in through windows — but the actual source is mold growing in 1970s flex-duct runs added to basements and crawlspaces that never had adequate vapor control, a pattern specific to these retrofitted river-town homes. The windows aren’t the problem. The ducts are.
Pricing for Air Duct Cleaning in Nyack, NY
| Service | Typical Range in Nyack |
|---|---|
| Residential full system cleaning (avg. 8–12 vents) | $280–$480 |
| Large Victorian or multi-zone system (15+ vents) | $450–$580 |

| Duct sealing and repair (per linear foot) | $8–$15 |
| Commercial system (call for scope) | $500–$1,200+ |
What moves you within these ranges? Number of vents and branches, accessibility of duct runs (closets and knee-walls take longer), contamination level, and whether we find mold requiring antimicrobial treatment. Nyack’s older homes trend toward the higher end — not because we charge more, but because retrofitted systems simply have more linear footage, more seams, and more problem areas to address properly. We assess on-site and give you an exact number before starting. Estimates are free. Call (833) 754-6107.

FAQs — Air Duct Cleaning in Nyack
The musty smell is almost certainly mold in your retrofitted ductwork, not outside air. Nyack’s position directly on the Hudson River’s western bank creates a persistently humid microclimate that accelerates mold and biofilm growth inside any duct system with imperfect sealing — and 1970s flex-duct retrofits are rarely sealed well. We find active mold colonies in crawlspace and basement duct runs on a regular basis. Call (833) 754-6107 for a video inspection — estimates are free.
Yes, when done with the right equipment and follow-up treatment. Our Rotobrush agitation combined with HEPA-contained negative pressure extraction removes visible mold and debris from flex-duct, metal pipe, and ductboard. For active colonies, we apply an antimicrobial treatment after cleaning and identify any vapor barrier or sealing failures that allowed the mold to establish. On that South Franklin Street job, the mold returned zero calls after we sealed the crawlspace barrier. Call (833) 754-6107 to schedule.
Every 3–5 years for most homes, but every 2–3 years for Nyack’s older housing stock with retrofitted systems. The irregular routing, extra seams, and elevated humidity from the river microclimate accelerate debris accumulation and mold risk. If you’ve recently renovated a historic home on Depew Avenue or South Highland, schedule a cleaning immediately — construction dust finds every gap in old ductwork. Call (833) 754-6107 to set a baseline.
Absolutely — flex-duct is a specialty of ours, and it’s what we encounter most in Nyack’s Victorian conversions. We use lower-agitation settings and camera guidance to clean flex-duct without damaging the fragile inner liner, then inspect for collapses, kinks, and disconnections that are epidemic in these retrofits. Many crews avoid flex-duct or damage it. We’ve been handling it for 20 years. Call (833) 754-6107.
Knee-wall cavities in upstairs bedrooms, closet chases on upper floors, and crawlspace runs beneath porches and additions. These were never designed as duct channels — they became duct channels because installers in the 1970s had no better path through balloon-framed walls and irregular floor plans. They require specialized reach tools, camera navigation, and patience. We budget extra time for these runs on every Nyack estimate. Call (833) 754-6107 for a scope-specific quote.
