Lennox Air Duct Cleaning in Tyngsboro, MA | Titan Air Duct Cleaning Lowell
We provide independent Lennox service throughout Tyngsboro, MA — not manufacturer-authorized, but built on 14 years of hands-on work with Lennox forced-air systems in the Merrimack River valley, collaborating with Lennox specialists. The one thing that makes our Lennox work here different: we treat Tyngsboro’s river-valley humidity and flood history as part of the job, not an afterthought. Call (877) 517-5646 for a free estimate.
Why Tyngsboro Residents Choose Us for Lennox Service
Thomas Hernandez grew up in Lowell’s Centralville neighborhood and picked up his mechanical foundation at Middlesex Community College — he’s been working on duct systems ever since. When he shows up to a Tyngsboro home, he’s the owner and the technician doing the work. That matters because Lennox systems in this town have seen things: basement floods that leave silt in return boots, humidity that turns flex ducts into soggy sleeves, coil fouling that makes a Merit Series furnace groan through July.
We carry professional-grade equipment — Rotobrush, Nikro, and Abatement Technologies — the same platforms used on commercial remediation jobs. We don’t delegate to a crew you’ve never met. And we’ll show you what’s in there before we tell you what it costs. Our 389 verified reviews averaging 4.7 stars come from people who’ve watched us do exactly that.
Common Lennox Air Duct Cleaning Problems We Solve in Tyngsboro
- Mold and silt in duct boots from Merrimack flood intrusion. Homes off Westford Road and along the riverfront have taken water in past flood events. We regularly find Lennox return duct boots with visible mold and dried silt — contamination that a standard maintenance clean won’t touch. We use HEPA vacuum extraction and antimicrobial treatment, not just a rotary brush.
- Flex-duct sagging in 1980s–1990s colonial basements. Tyngsboro’s suburban buildout left thousands of homes with original flex duct suspended in unconditioned basements. River-valley humidity weakens straps and hangers; we’ve found disconnected runs that were dumping conditioned air into crawl spaces for years, bleeding efficiency from Lennox Elite Series furnaces.
- Evaporator coil fouling from persistent humidity. The Merrimack valley traps moisture all summer. Lennox Merit Series units — common in Tyngsboro’s entry-level colonials — short-cycle when their coils clog with dust mite debris and biological film. We pull and clean coils as part of full system service, not a separate upsell.
- iHarmony damper contamination from basement return air. The 1990s colonials with zoning systems pull return air through damp basement spaces. Dust mite debris and mold spores coat Lennox iHarmony dampers and zone controllers, causing them to stick or fail. Our cleaning protocol addresses the dampers directly — we don’t just vacuum past them.
- Disconnected trunk lines in flood-prone crawl spaces. Low-lying areas near the Nashua River confluence have ductwork routed through spaces that see seasonal moisture. We’ve resealed and rehung Lennox trunk lines that had separated at joints, restoring airflow to second-floor zones that had gone stale.
Lennox Service in Tyngsboro: What Local Conditions Mean for Your Equipment
Tyngsboro sits where the Merrimack and Nashua Rivers meet, and that geography doesn’t stay outside. The town’s extensive wetlands and low-lying floodplain create ambient humidity levels that push well above what you’d find in Dunstable or Westford just a few miles west. For Lennox forced-air systems — particularly the Merit and Elite Series furnaces installed during the 1980s and 1990s buildout — this means evaporator coils working harder, flex duct absorbing moisture and losing structural integrity, and return vents in basements pulling air that’s already laden with biological particulate.
Our crew recently cleaned a 20-year-old Lennox Merit Series system in a colonial home on Westford Road in Tyngsboro. The unit had been struggling with low airflow and musty odors, and our video inspection revealed mold and silt residue in the return duct boot from a past basement flood. We performed a full system cleaning with a HEPA vacuum, treated the duct interior with an antimicrobial coil cleaner, and sealed a disconnected flex run in the crawl space, restoring airflow and eliminating odor. That’s not a standard clean. That’s Tyngsboro-specific remediation.
Lennox Models & Products We Service in Tyngsboro
We work on the full Lennox residential lineup common in Tyngsboro’s housing stock: the builder-grade Merit Series (M1, M2 gas furnaces), the mid-tier Elite Series (EL296V, EL18XCV), and the premium Signature Collection (SLP99V furnace, SL28XCV condenser). We also service iHarmony zoning systems, frequently paired with dampers in the 1990s colonials that dominate this market.
For critical components — burners, heat exchangers, control boards — we source Lennox OEM-compatible parts. For non-critical items like flex duct or filter grilles, we use high-quality aftermarket alternatives and tell you exactly which is which. We don’t stock everything, but we know which Tyngsboro suppliers can turn a Signature Collection board same-day, and we plan accordingly.
Lennox Service Pricing in Tyngsboro
Most Lennox air duct cleaning jobs in Tyngsboro fall between $350 and $650 for a full system clean on a typical single-family colonial. Here’s how that breaks:
- Full system cleaning (standard): $350–$450 — covers supply and return ducts, main trunk lines, and register/grille cleaning for a home up to 2,500 sq ft.
- Full system cleaning with evaporator coil service: $450–$550 — adds coil pull-and-clean, critical for Merit Series units showing summer short-cycling.
- Remediation-grade cleaning with antimicrobial treatment: $550–$650 — for flood-affected systems with visible mold or silt, common in lower Westford Road and riverfront properties.
- Video inspection: Included with all full-system quotes — we’ll show you the contamination before pricing the work.
- Duct repair and sealing: $150–$400 additional, depending on linear feet of flex duct or number of disconnected joints.
Every estimate starts with a free inspection. No charge to look, no pressure to book. Call (877) 517-5646 and we’ll schedule a time that works — Thomas handles the estimate personally.

FAQs — Lennox Air Duct Cleaning in Tyngsboro
Clean first, then decide. A 20-year-old Lennox Merit Series can run efficiently if the ductwork is clear and sealed; we’ve extended the useful life of plenty of Tyngsboro units by restoring airflow rather than selling a replacement. If the heat exchanger shows cracks or the blower motor is failing, we’ll tell you straight — no cleaning fixes that. Call (877) 517-5646 for a free inspection and honest assessment.
Yes. The Merrimack River valley holds moisture that drier inland communities don’t experience, which means dust mite debris, biological growth, and coil fouling accumulate faster here. A Lennox system in Tyngsboro typically needs cleaning on a shorter interval than the same unit in Westford, where we also offer Lennox service in Westford, or Dunstable. We see the difference in our video inspections — the buildup pattern is distinct. Call (877) 517-5646 to check your system’s condition.
Yes. We clean around iHarmony dampers using low-pressure HEPA vacuum and soft-bristle contact — never aggressive rotary brushes that can jam or bend damper blades. We also inspect each zone controller for dust accumulation that causes sticking. If a damper is already failing, we’ll show you before we touch it. Call (877) 517-5646 to schedule zone-aware service.
The Signature Collection is Lennox’s premium tier — variable-capacity furnaces like the SLP99V and communicating condensers like the SL28XCV. These systems have tighter tolerances and more complex control boards, but the ductwork itself cleans similarly. The difference: Signature systems are more sensitive to airflow restriction, so a clogged duct hits efficiency harder than on a basic Merit unit. We treat them with the same thoroughness, just with extra attention to static pressure readings. Call (877) 517-5646 for Signature-specific service.
Insulation helps, but sealing comes first. Unsealed ducts in a damp Tyngsboro crawl space pull in ambient moisture and spores, then distribute them through the house. We seal joints and disconnects with mastic, then evaluate whether insulation is worth the investment based on your specific crawl space conditions. Some Tyngsboro homes need both; some just need the leaks stopped. Call (877) 517-5646 for a crawl space duct assessment — estimates are free.
