Why Nanuet Residents Choose Us for Lennox Service
We’ve cleaned more than 800 Lennox systems across Rockland County, from Lennox service in Montvale to Nanuet, and this area’s 1950s–70s housing stock keeps us busy year-round. Richard Anderson — owner and lead technician — handles your job personally. He grew up in Woodside, Queens, learned HVAC mechanics at New York City College of Technology in Brooklyn, and has spent two decades pulling apart ducts in just about every building type New York throws at you. That matters in Nanuet, where original galvanized steel and degrading fiberglass duct board require someone who’s seen it before, not a franchise tech reading from a script.
Our equipment comes from Rotobrush, Nikro, and Abatement Technologies — the same brands commercial contractors use. We stock OEM Lennox filters, belts, and capacitors for immediate replacement, and our 4.9-star average across 548 verified reviews reflects what happens when the person who built the business is the person doing the work. “I’ll tell you what you need. I won’t sell you what you don’t.” That’s how Richard built this company on word-of-mouth referrals.
Common Lennox Air Duct Cleaning Problems We Solve in Nanuet
- CBX32MV evaporator coil mold colonization. Nanuet’s valley position traps humid Hudson Valley air that keeps indoor moisture elevated year-round. We’ve found Lennox Elite CBX32MV coils growing mold within 18 months when crawlspace duct joints aren’t sealed — the humidity wicks straight into fiberglass-lined plenums. Our evaporator coil cleaning includes antimicrobial treatment and mastic sealing of those access points.
- G16 Merit secondary heat exchanger corrosion. The compact ranch homes built during Nanuet’s 1955–1975 suburban boom used narrow plenums designed for oil-fired heat. When condensation from modern gas combustion gets trapped in those original channels, the G16’s secondary exchanger corrodes prematurely. We video-inspect before cleaning to assess whether corrosion has compromised the metal.
- SL280V modulating blower CFM loss. Nanuet’s split-level retrofits from the 1980s–90s squeezed flex-duct runs through tight framing. Decades of compacted debris in those runs push static pressure beyond what the Signature SL280V’s variable-speed blower was designed to handle. We measure static pressure before and after cleaning — you’ll see the numbers.
- Blower wheel imbalance from rodent nesting. Original Lennox air handlers in Cape Cods along Summit Avenue and similar streets pull nesting material through unsealed return chases. The debris coats blower wheels unevenly, creating vibration that wears bearings. Our HEPA vacuum extraction removes the material without disbalancing the wheel further.
- Flex-duct insulation compression and debris traps. Those retrofitted cooling systems in Nanuet’s ranch and split-level homes used flex duct where rigid should have gone. The sagging runs collect condensation, skin cells, and construction dust from decades of occupancy. We use contractor-grade Rotobrush systems that clean without crushing the insulation lining.
Lennox Service in Nanuet: What Local Conditions Mean for Your Equipment
Nanuet sits in a geographic low between the Ramapo Mountains to the west and the Palisades ridge to the east — a position that creates a humidity pocket no neighboring community experiences to the same degree. In New City or Chestnut Ridge, elevated terrain lets moisture disperse. In Nanuet, it settles into crawl spaces, basements, and the fiberglass duct board that contractors favored during the 1960s–70s building boom. For Lennox owners, this means mold colonization inside ductwork isn’t a possibility — it’s a probability if the system hasn’t been professionally cleaned and sealed within the last five years.
Spring compounds the problem. Prevailing westerlies carry heavy pollen loads from Harriman State Park’s hardwood forests just to the northwest, and that organic particulate filters into Nanuet homes through every gap in the building envelope. Once inside, it meets the humid microclimate and begins decomposing in duct interiors — the source of that musty odor many homeowners blame on their basements when it’s actually their supply registers. We’ve traced this exact pattern in Lennox systems from South Grandview Avenue to Lennox in Blauvelt and the quieter ranch neighborhoods with raised foundations where ductwork runs through crawl spaces most residents never enter.
Lennox Models & Products We Service in Nanuet
We work on the full Lennox residential line, with particular depth in the systems most common to Nanuet’s housing stock:
- Merit Series: G16 and G20 gas furnaces — the workhorses of 1960s ranch retrofits. We stock OEM filters, belts, and capacitors for same-visit replacement.
- Elite Series: G51 furnaces and CBX32MV air handlers — frequent finds in split-levels with attic flex-duct runs. We carry OEM evaporator coils for clean replacements when corrosion has advanced too far for cleaning alone.
- Signature Collection: SL280V modulating furnaces and CBX40UHV variable-speed air handlers — premium systems where debris-induced static pressure losses waste the efficiency homeowners paid for.
For duct components — flex duct, mastic, sealants — we use high-quality aftermarket materials that meet or exceed Lennox specifications. We advise repair over replacement whenever cleaning and sealing can restore design airflow. That’s the difference between a specialist and a salesman.
Lennox Service Pricing in Nanuet
Most complete Nanuet Air Duct Cleaning jobs for Lennox systems fall between $350 and $850, depending on system accessibility and contamination level. Here’s how that breaks down:

FAQs — Lennox Air Duct Cleaning in Nanuet
Yes. We use adjustable-suction HEPA systems and soft-bristle Rotobrush heads that clean galvanized steel without abrading the zinc coating. On a Lennox G16 Merit furnace in a 1963 split-level on South Grandview Avenue, our video inspection discovered 2 inches of compacted debris and rodent nesting in the flex-duct supply run to the west bedroom — evidence of the crawlspace access problems common in Nanuet’s raised-foundation builds. We fabricated a custom access panel, HEPA-vacuumed the run, and sealed the return-chase gaps with mastic, restoring airflow from 780 CFM to 1,100 CFM and eliminating the musty odor the homeowner had tolerated for years. For your 1965 ranch, we’ll video-inspect first to locate any weak joints before cleaning begins. Call (833) 754-6107 to schedule.
The odor is almost certainly mold or decomposing organic matter inside your ductwork, not the filter. Nanuet’s valley humidity keeps moisture levels inside fiberglass-lined ducts high enough for year-round mold growth, and spring pollen from Harriman State Park adds material that decomposes in that damp environment. Filters catch what passes through them; they don’t clean what’s already growing on duct walls or evaporator coils. We address this with antimicrobial treatment, coil cleaning, and mastic sealing of humid air infiltration points. Call (833) 754-6107 — we’ll pinpoint the source with video inspection.
Yes. We use Nikro and Rotobrush equipment with adjustable torque settings specifically to avoid crushing flex-duct insulation. Nanuet’s 1980s–90s AC retrofits squeezed many of these runs through tight attic framing where they already sag and compress over time. Our cleaning process actually improves their shape by removing the debris weight that’s pulling them down. We measure airflow before and after so you can verify the improvement. Call (833) 754-6107 for an assessment of your specific runs.
Yes — video inspection is standard on every Lennox job we do in Nanuet. In homes with 50+ year old ductwork, we won’t quote cleaning without seeing what we’re dealing with first. The camera reveals corrosion points, disconnected joints, rodent entry paths, and mold colonization that a visual register check would miss. You watch the feed with us; there’s no mystery about what needs work and what doesn’t. Call (833) 754-6107 to schedule your inspection.
Very likely. The SL280V’s modulating blower is sensitive to static pressure increases, and Nanuet’s crawlspace duct runs commonly accumulate decades of debris while drawing humid, particle-laden air through unsealed return chases. We’ve restored full airflow to SL280V systems where cleaning and sealing dropped static pressure by 30% or more. Before you consider replacing the blower motor, let’s measure the pressure and inspect the duct path. Call (833) 754-6107 — estimates are free, and the diagnostic alone often reveals the real culprit.
