We provide independent Sheepshead Bay Air Duct Cleaning for Lennox HVAC systems throughout Brooklyn — not manufacturer-authorized, but owner-operated with 20 years of specialized experience in coastal New York conditions.

Why Sheepshead Bay Residents Choose Us for Lennox Service
Richard Anderson — owner and lead technician — handles your job personally. That’s not a slogan; it’s how Landmark Air Duct Cleaning has operated for two decades. Richard grew up in Woodside, Queens, a few blocks from the elevated 7 train, and learned the mechanical side of HVAC systems at New York City College of Technology in Brooklyn. He’s spent the last 20 years inside ducts in just about every building type New York throws at you — pre-war walk-ups, high-rise condos, commercial kitchens, and the tight basement installations that dominate Sheepshead Bay’s 1950s–1960s housing stock.
We’re not a franchise. Not a subcontractor network. Richard built this business on word-of-mouth referrals from customers who appreciated being told what they actually needed versus what they didn’t. Our 4.9-star average across 548 verified reviews reflects that same straight approach. For Bensonhurst Lennox service and equipment in Sheepshead Bay, we bring contractor-grade Rotobrush, Nikro, and Abatement Technologies systems — the same brands industrial contractors use — into residential jobs where salt corrosion and legacy flood damage demand more than a standard vacuum pass.
From cleaning to repair to sanitizing, one call closes the loop on your air quality. No second contractor needed.
Common Lennox Air Duct Cleaning Problems We Solve in Sheepshead Bay
- Saltwater corrosion of Lennox aluminum coils — Sheepshead Bay’s peninsula position between the Atlantic and Jamaica Bay creates marine humidity levels measurably higher than inland Brooklyn. That salt-laden air penetrates basement HVAC installations and attacks Lennox Elite and Merit Series coils with pinhole leaks that reduce efficiency long before total failure. We treat the corrosion, seal the leaks, and coat vulnerable surfaces.
- Mold colonization inside duct liners from post-Sandy silt — The 2012 storm surge deposited fine gray-brown silt along Emmons Avenue and surrounding blocks. Standard cleaning misses this substrate; mold recurs within months. Our negative-air HEPA system removes the silt layer entirely, then we apply antimicrobial mastic to seams where spores would otherwise reestablish.
- Degradation of Lennox icomfort thermostat sensors — Conductive salt film builds on circuit boards in Sheepshead Bay’s persistently damp basements. The thermostat reads wrong, cycles irregularly, or fails entirely. We clean the board and sensor housing with electronics-safe solvents, then recommend humidity control strategies specific to waterfront properties.
- Blower motor bearing failure from silt grinding — Original forced-air ductwork in Sheepshead Bay’s post-WWII two-families was never designed for easy access. Decades of accumulated debris — compounded by Sandy residue — works its way into blower assemblies. The Rotobrush system we deploy extracts this grit without disassembling components that are often seized in place.
- Rust-through of Lennox plenums from tidal moisture wicking — Sheepshead Bay’s 1950s–60s brick homes, built on reclaimed marshland, have duct trunks routed through crawl spaces that experience moisture wicking absent even in nearby Gravesend. We find Lennox plenums rusting from the bottom up within a decade. Our repair includes sealing the crawl space penetration and coating the plenum interior.
Lennox Service in Sheepshead Bay: What Local Conditions Mean for Your Equipment
Lennox in Bath Beach and Sheepshead Bay share a tidal inlet flanked by the Atlantic Ocean to the south and Jamaica Bay to the north, creating a persistently salt-laden, high-humidity microclimate that accelerates mold colonization and metal corrosion inside ductwork faster than virtually any other Brooklyn neighborhood. Compounding this, Hurricane Sandy’s 2012 storm surge severely flooded basements along Emmons Avenue and surrounding blocks, leaving silt, moisture, and mold spores embedded in duct systems that many homeowners never had professionally remediated — making legacy flood contamination a recurring discovery unique to this waterfront pocket of Brooklyn.
For Lennox owners specifically, this means trouble that shows up differently here than in Flatbush or Lennox repair in Coney Island. The salt film that coats icomfort thermostat circuit boards? More aggressive here. The pinhole corrosion in Merit Series coils? Faster progression. The mold that returns after a standard cleaning? It’s feeding on Sandy silt the previous crew never removed. On a service call at a two-family home on Emmons Avenue, our video inspection revealed a Lennox Elite Series supply trunk packed with dried silt lines from Hurricane Sandy, layered under 10 years of compacted mold. We deployed a HEPA vacuum with negative-air containment, followed by an antimicrobial mastic coating on all interior duct seams. The homeowner reported no musty odors for the first time since the storm.
That’s the difference between a generic duct cleaning and one that accounts for where your house sits, when it flooded, and what your Lennox system has been breathing since.
Lennox Models & Products We Service in Sheepshead Bay
We work on the full residential and light-commercial Lennox line: Elite Series, Signature Series, and Merit Series furnaces and air handlers, plus icomfort Wi-Fi thermostats. For parts, we use OEM Lennox replacements on critical components — coils, blower motors, control boards — where factory tolerances matter. For non-critical items like flex duct or mastic sealant, we prefer quality aftermarket equivalents that match OEM specs and hold up better in Sheepshead Bay’s corrosive environment.
Our van stocks common Lennox wear items for 11235 service calls, including coil treatments rated for salt-air exposure and bearing assemblies sized to the compact blower housings found in Sheepshead Bay’s tight basement installations. Most repairs don’t require a second trip.
Video inspection, full system cleaning, and coil treatment are our core offerings on every Lennox job.

FAQs — Lennox Air Duct Cleaning in Sheepshead Bay
Yes — we clean original galvanized ductwork regularly in Sheepshead Bay’s post-WWII housing stock. Our Rotobrush system uses flexible, nylon-bristle brushes sized to older duct diameters, not the aggressive wire brushes that scar thin metal. We pair this with controlled suction so nothing gets forced through rust-weakened seams. The musty odor you smell is almost certainly mold feeding on decades of organic debris, possibly compounded by post-Sandy moisture intrusion. We’ll show you the video evidence before we start. Call (833) 754-6107 to schedule — estimates are free.
The corrosion is from salt air — Sheepshead Bay’s marine humidity deposits conductive film that pits aluminum coils within 5–7 years, faster than inland Brooklyn. For Signature Series units under 10 years old with localized coil damage, we replace just the coil assembly with OEM Lennox parts rather than recommending full unit replacement. If the corrosion has spread to the cabinet or blower housing, we’ll show you and explain why. Call (833) 754-6107 for an inspection — estimates are free.
Near the inlet, it’s usually mold — specifically Cladosporium or Aspergillus species that thrive on the constant humidity. We don’t guess; our video inspection identifies growth patterns, and we can collect samples for lab analysis if you need documentation for insurance or health purposes. The black dust around registers means the colony is established enough to release spores into your airflow. We treat with HEPA extraction and antimicrobial coating. Call (833) 754-6107 — we’ll confirm what it is and what it needs.
In most cases, yes. We’ve removed Sandy silt from dozens of Sheepshead Bay systems without duct replacement. The key is negative-air containment — we seal the system and extract under vacuum so disturbed silt doesn’t enter your living space. Then we coat interior seams to prevent mold reestablishment. Tearing out ducts is only necessary when galvanized metal has rusted through or fiberglass liners have delaminated; we’ll tell you honestly if that’s your situation. Call (833) 754-6107 for a video inspection — estimates are free.
Yes — we service icomfort thermostats, including sensor cleaning and recalibration. The salt film that builds on circuit boards in Sheepshead Bay’s damp basements causes drift or erratic readings. We disassemble the housing, clean the board with electronics-grade solvent, and recalibrate against known temperature and humidity references. If the board is too far gone, we install OEM replacements. Call (833) 754-6107 — we’ll diagnose whether it’s a cleaning fix or a parts replacement.
