Lennox Air Duct Cleaning in Cedarhurst, NY | Landmark Air Duct Cleaning Service New York
Lennox sales & service for air duct cleaning in Cedarhurst, NY typically runs $280–$480 for a full system cleaning, with most jobs completed in a single visit. What sets our work apart is this: we’ve cleaned more than 500 Lennox systems in Cedarhurst and the Five Towns, and we’ve learned that the salt-laden marine air off Jamaica Bay creates corrosion and mold patterns inside Lennox ductwork that inland Nassau technicians simply don’t encounter. Richard Anderson — owner and lead technician — handles your job personally, bringing 20 years of focused duct specialization and contractor-grade Rotobrush and Nikro equipment to every Cedarhurst home.

Why Cedarhurst Residents Choose Us for Lennox Service
Richard Anderson grew up in Woodside, Queens, a few blocks from the elevated 7 train, and has spent the last 20 years on Cedarhurst Air Duct Cleaning and ductwork in just about every type of building New York throws at you. That background matters in Cedarhurst, where the housing stock — post-WWII Cape Cods and colonials from the 1940s through 1960s — demands a technician who understands how original rectangular sheet-metal ductwork behaves after decades of coastal exposure. We’re not a franchise crew rotating through subcontractors. Richard is the person who built Landmark on word-of-mouth referrals, and he’s the person who shows up with the Rotobrush and Abatement Technologies gear.
Our 548 verified reviews averaging 4.9 stars reflect something simple: we know Lennox duct layouts cold. The Signature Series SLP98V, the Merit Series ML14XC1, the Elite Series CB29M, the G71MPP — we’ve cleaned, inspected, and repaired them all in Cedarhurst conditions. We carry OEM Lennox motors, boards, and sensors for critical repairs, and we stock high-quality aftermarket seals and mastics for ductwork restoration. When chloride corrosion has thinned fin stock on a coastal-exposed coil, we’ll tell you straight that replacement beats repair. That’s saved more than a few Cedarhurst homeowners from throwing good money at a part that’ll fail again in two seasons.
I’ll tell you what you need. I won’t sell you what you don’t.
Common Lennox Air Duct Cleaning Problems We Solve in Cedarhurst
- Rust-through at CB29M air handler trunks. The Elite Series CB29M’s sheet-metal construction sits vulnerable in Cedarhurst’s marine environment. Salt-laden humidity wicks through unsealed slab penetrations and attacks the bottom of trunks from the outside in. We’ve found rust holes in 10-year-old systems that inland technicians would mistake for 25-year-old wear. Our video inspection catches it before the homeowner smells it.
- SLP98V flex-duct collar degradation. Lennox’s premium Signature Series uses flex-duct connectors that turn brittle in persistent humidity. Cedarhurst’s year-round relative humidity — sustained by Jamaica Bay proximity — accelerates liner fiber shedding. Those fibers circulate through your supply vents. We replace compromised collars with marine-rated material during cleaning.
- ML14XC1 evaporator coil pitting. The Merit Series ML14XC1’s coils suffer chloride-induced pitting that’s unique to coastal environments. Standard cleaning agents can’t prevent the micro-leaks that follow. In Cedarhurst, we inspect fin stock thickness before we clean — if corrosion has thinned it past spec, we recommend coil replacement over cleaning, saving you the callback.
- Return-air plenum biofilm recurrence. Older Lennox installations in Cedarhurst basements face dewpoint levels above 60°F even in shoulder seasons. Biofilm re-establishes within 18 months of a surface cleaning. We address this with full plenum access, mechanical agitation, and sanitizing — not just a vacuum pass.
- Post-Sandy sediment contamination in G71MPP systems. The 2012 surge flooded hundreds of Cedarhurst basement mechanical rooms. Many homeowners replaced the furnace but left the ductwork. We still find fine silt and mold-compromised liner in G71MPP supply trunks, particularly in the blocks between Peninsula Boulevard and Maple Avenue. Our cleaning protocol includes full trunk inspection and liner assessment.
Lennox Service in Cedarhurst: What Local Conditions Mean for Your Equipment
Cedarhurst’s 11516 ZIP contains the highest density of post-Sandy mold-compromised Lennox ductwork in Nassau County. The 2012 tidal surge flooded hundreds of basement mechanical rooms in the blocks between Peninsula Boulevard and Maple Avenue, and many homeowners replaced only the furnace, not the contaminated duct system. That decision — understandable at the time, when contractors were scarce and homeowners needed heat before winter — created a persistent problem we encounter weekly. The original ductwork, already aged by Cedarhurst’s salt-laden marine air, absorbed floodwater and sediment that accelerated liner degradation and introduced mold colonies deep in trunk lines. A Lennox furnace replacement with clean equipment connected to dirty ducts simply recirculates contamination. We’ve pulled apart systems where the new G71MPP furnace was spotless and the supply trunk behind it was shedding fiberglass particles compromised by a decade of post-flood biological growth. For Lennox owners in this specific Cedarhurst corridor, our cleaning protocol includes video inspection of the full trunk run, liner integrity testing, and — when indicated — full duct sealing with marine-grade mastic before we certify the system clean. This isn’t generic duct cleaning adapted to Lennox. It’s Lennox-specific service shaped by a local disaster’s lingering footprint.
Lennox Models & Products We Service in Cedarhurst
We clean and service the full range of Lennox residential systems found in Cedarhurst homes:
- Signature Series SLP98V — Premium modulating furnaces with complex flex-duct networks requiring careful collar inspection
- Merit Series ML14XC1 — Workhorse AC units where coil pitting from chloride exposure demands fin-stock assessment
- Elite Series CB29M — Air handlers with sheet-metal trunks vulnerable to salt-air rust-through
- G71MPP — Older high-efficiency furnaces common in post-Sandy replacement jobs with legacy duct contamination
We stock OEM Lennox motors, boards, and sensors for repairs that require manufacturer-spec parts. For ductwork restoration, we use high-quality aftermarket seals and mastics — marine-grade formulations that hold up to Cedarhurst’s humidity better than standard hardware-store products. Our Nikro and Rotobrush equipment handles both rigid metal and flexible duct configurations, and our Abatement Technologies HEPA containment protects your space during aggressive cleaning. Most Cedarhurst jobs don’t require a parts order delay. We carry what breaks.

FAQs — Lennox Air Duct Cleaning in Cedarhurst
Every 18 to 24 months for homes within three blocks of the bay, versus the standard 3- to 5-year interval for inland Nassau. The salt-laden humidity accelerates particulate accumulation and biofilm growth in Lennox return plenums. Call (833) 754-6107 — we’ll assess your specific exposure and give you a schedule that matches your conditions, not a generic calendar.
Yes, especially if your home is between Peninsula Boulevard and Maple Avenue in the 11516 ZIP. Many 2008-era furnaces were replaced after Sandy while the connected ductwork was left in place. Our video inspection can confirm whether you’re pulling air through contaminated trunk lines. Call (833) 754-6107 for a free assessment — the inspection itself takes under an hour.
We use the same professional-grade Rotobrush and Nikro equipment across brands, but the technique and attachment selection vary by Lennox model. The SLP98V’s narrow flex-duct runs require different brush sizing than the CB29M’s rigid rectangular trunks. Our 500-plus Lennox repair in South Valley Stream and Cedarhurst jobs have refined those choices.
We access crawl-space ductwork through basement mechanical rooms and existing service openings whenever possible. When crawl entry is unavoidable, we use portable HEPA containment and protective protocols — but most Cedarhurst Cape Cod systems from the 1940s-1960s have enough access points that we don’t need to. Richard Anderson evaluates access during your free estimate.
No — we’re an independent service provider, not a Lennox authorized dealer, so our cleaning doesn’t carry manufacturer warranty implications. What it does provide is documented maintenance history that supports insurance claims and resale value, plus the operational benefit of restored airflow and reduced strain on your equipment. For warranty-specific service, contact a Lennox dealer; for honest, thorough cleaning by a technician who knows these systems in Cedarhurst conditions, call (833) 754-6107.

Last fall, our crew worked on a 1949 Cape Cod on Maple Avenue where the Lennox G71MPP furnace kept tripping on high-limit. Our video inspection revealed the original sheet-metal supply trunk had a rusted-through seam from 11 years of bay-humidity wicking through a unsealed slab penetration, pulling in fine silt. We sealed the seam with marine-grade mastic, cleaned the entire trunk and coil, and restored airflow to manufacturer spec — Dryer Vent Cleaning in Cedarhurst is another service we offer, and we avoided the $2,800 furnace replacement the homeowner had been quoted by another contractor.
That’s the difference 20 years of focused duct work makes. Richard Anderson — owner and lead technician — handles your job personally, not a rotating crew. Same-day appointments often available for Cedarhurst calls. Get your free estimate at (833) 754-6107.
