Why Hicksville Residents Choose Us for Lennox Service
Richard Anderson — owner and lead technician — handles your job personally. Two decades of duct work, not generalist HVAC services. That’s the difference between calling a franchise dispatcher and calling someone who’ll actually show up with contractor-grade equipment most residential crews never carry.
We’ve completed over 500 Lennox-specific duct cleaning jobs across Hicksville’s 11815, 11819, 11854, and 11855 ZIP codes, including Salisbury Lennox service nearby. We know the Merit Series filter cabinets, the Elite Series variable-speed quirks, and the Signature Collection blower calibrations that standard cleaners miss. Our Rotobrush, Nikro, and Abatement Technologies systems are the same brands commercial contractors use — brought into your split-level on Jerusalem Avenue or your Cape Cod near the train station.
Richard grew up in Woodside, Queens, a few blocks from the elevated 7 train, and learned the mechanical side of HVAC at New York City College of Technology in Brooklyn. He’s pulled apart ducts in pre-war walk-ups, high-rise condos, and the exact 1950s–60s Nassau County ranches that dominate Hicksville. “I’ll tell you what you need. I won’t sell you what you don’t.” 548 customers, 4.9 stars — results you can verify before you book.
Common Lennox Air Duct Cleaning Problems We Solve in Hicksville
- Variable-speed blower motor surging on Signature SL28XV and SL18XC units. Debris loads unbalance the blower wheel, causing calibration loss and error codes. In Hicksville, this hits harder because Cape Cod knee-wall attics — those tight, poorly-ventilated spaces where duct runs hide — trap humidity that glues dust to the wheel unevenly. We’ve restored dozens of these systems in original 1950s builds near Frank Avenue.
- Heat exchanger micro-cracks in Merit and Elite furnaces. The 1960s ranches along Woodbury Road and Jerusalem Avenue have seasonal shutdown patterns that trap moisture in heat exchangers during shoulder seasons. The resulting micro-cracks mimic dirty duct symptoms — uneven heating, musty startup smells — but need immediate part replacement, not just cleaning. Richard Anderson flags this distinction during every inspection.
- PCO air cleaner UV lamp failure from salt-laden humidity. Lennox Healthy Climate duct-mounted units in post-war split-levels near the Great South Bay corridor fail prematurely when UV lamps coat with corrosive moisture. We clean the full optical chamber and replace lamps with OEM-compatible units rated for coastal humidity exposure.
- iComfort thermostat sensor misreads from buried supply registers. In 1950s–60s Hicksville homes where decades of attic debris and renovation dust have packed around supply registers, return air temperature readings skew low. The system overcooling that follows freezes coils and spikes energy bills. Our video inspection locates buried registers; thorough duct cleaning and sensor calibration fixes the root cause.
- Hidden dead-leg flex duct sections from 1980s–90s HVAC replacements. Technicians here routinely find that original rigid metal runs were capped with flex duct “upgrades,” creating stagnant sections that never see airflow. These accumulate decades of mold and dust — a layered mess we map with video inspection and clear with rotary brushing and targeted sanitizing.
Lennox Service in Hicksville: What Local Conditions Mean for Your Equipment
Hicksville’s position in central Nassau County pulls humid air from both the Great South Bay and Long Island Sound, keeping indoor moisture elevated well into October. That sustained load hits Lennox in Levittown and Hicksville differently than it would in drier inland markets. The variable-speed blowers in Elite and Signature units — designed to modulate airflow precisely — lose that precision when microbial buildup from months of high humidity throws off wheel balance.
Here’s something you won’t find on a generic service page: alongside our Air Duct Cleaning in Hicksville, we know that 1950s–60s Cape Cods nearly all contain original sheet-metal duct trunks tagged with lead-based paint numbers by the original HVAC contractor. Those painted markings appear on supply plenums near the furnace — a local fingerprint that helps us trace unaltered systems still sealed with tape from 1958. When we find those tags intact, we know we’re looking at ductwork that has never been properly cleaned, and we adjust our approach accordingly. Solvent pre-treatment before rotary brushing protects aging metal. Duct sealing with modern mastic replaces brittle original tape. The result is a system that breathes like it should without destroying its own history.
Winters bring salt-laden air that corrodes older sheet-metal connections, creating leakage points that draw in attic or wall-cavity particulates. For New Cassel Lennox service customers and other local owners, that means MERV-rated filter cabinets load faster and variable-speed motors work harder against restricted flow. We address the leaks at source — duct sealing is standard in our Hicksville protocol — rather than just swapping filters and hoping.
Lennox Models & Products We Service in Hicksville
We clean and service the full Lennox residential range: Merit Series including ML14XC1 air conditioners and ML180UH furnaces; Elite Series including EL18XCV variable-speed units and EL296UHV high-efficiency furnaces; Signature Collection including SL28XCV and SLP99V modulating systems; and legacy workhorses like the G60DF gas furnace still running in original Hicksville builds.
Our parts approach is straightforward: OEM Lennox filters and variable-speed blower motors to maintain factory airflow curves; high-quality aftermarket capacitors, contactors, and standard hardware where exact OEM spec isn’t critical for performance. We stock common Lennox filter sizes and blower components for fast Hicksville turnaround and Lennox repair in Westbury — no waiting on a franchise warehouse to ship from Syracuse. Full system replacement only enters the conversation when a unit exceeds 18 years or heat exchanger failure is confirmed. From cleaning to repair to sanitizing — one call closes the loop on your air quality.

FAQs — Lennox Air Duct Cleaning in Hicksville
No. Landmark Air Duct Cleaning Service New York is an independent service provider with no manufacturer affiliation. That independence lets us source OEM-compatible parts at lower cost and recommend only what’s actually needed — no corporate service bulletins pushing unnecessary add-ons. Richard Anderson, owner and lead technician, makes every diagnostic call himself.
Dryer Vent Cleaning — Hicksville aside, musty startup smells usually indicate microbial growth on the heat exchanger or in stagnant duct sections, not immediate carbon monoxide danger. However, the same moisture that causes that smell in Hicksville’s humid climate can also corrode heat exchangers — so we inspect for micro-cracks during every cleaning. If you smell burning or metallic odors, shut the system off and call (833) 754-6107 — we’ll prioritize same-day inspection.
Yes. Furnace replacement rarely includes full duct cleaning, and 1960s Hicksville ranches often have buried original trunk lines that new equipment simply ties into. We’ve found decades of accumulation in “updated” systems. Our video inspection shows you exactly what the previous owners left behind. Call (833) 754-6107 to schedule — estimates are free.
Every 18–24 months for homes within a half-mile of major transit corridors, where brake dust and particulate load filters and coils faster. The elevated humidity near Hicksville’s central Nassau County location accelerates coil fouling year-round, not just in summer. We include evaporator coil cleaning in our deep service package and inspect it during every standard cleaning.
Probably not. In 1950s–60s Hicksville homes, buried or debris-packed supply registers cause restricted return airflow, making the system think the filter is loaded. We clean the full duct run, verify register clearance, and recalibrate the iComfort sensor. Only after that do we recommend thermostat replacement. Call (833) 754-6107 — we’ll diagnose the real cause before selling you a new control.
Rarely. Our Rotobrush and Nikro systems access standard vents and return grilles; we only cut access panels when we find sealed dead-leg sections from 1980s–90s flex duct retrofits — a common issue in Hicksville split-levels. If cutting is necessary, we patch with code-compliant access doors, not temporary covers. Richard Anderson will show you the video evidence before any sheet metal gets touched.
