Lennox Air Duct Cleaning in South Boston, MA | Titan Air Duct Cleaning Lowell
We provide independent Lennox sales & service air duct cleaning service across South Boston, specializing in the retrofitted forced-air systems found in converted triple-deckers and rowhouses throughout 02127. Our work differs from standard residential cleaning because South Boston’s harbor-humidity climate and non-standard duct chases create contamination patterns you won’t find inland. Call (877) 517-5646 for a free estimate — Thomas Hernandez, our owner and lead technician, handles every job personally.
Why South Boston Residents Choose Us for Lennox Service
Fourteen years in this trade, and we’ve learned that Lennox systems in South Boston don’t behave like Lennox systems in Lowell or Tewksbury. The salt-laden air rolling off Boston Harbor and Fort Point Channel corrodes sheet-metal ductwork faster. The improvised duct chases in converted triple-deckers trap debris that purpose-built systems never see. We’ve worked on enough of them to know the difference.
Thomas Hernandez grew up in Lowell’s Centralville neighborhood, picked up his mechanical foundation at Middlesex Community College, and hasn’t strayed far since. He shows up as both the owner and the technician doing the work — not a subcontracted crew you’ll never see again. That matters in South Boston, where your ductwork runs through spaces a standard crew won’t even know to check. We carry Rotobrush, Nikro, and Abatement Technologies equipment — the same platforms used on commercial remediation jobs — because residential ductwork here often needs that level of intervention. 389 customers reviewed us. Read what they found.
We’re independent. Not Lennox-authorized, not manufacturer-endorsed. That means we use OEM Lennox parts when they make sense for critical components, and quality aftermarket when they don’t. No corporate service script. Just honest assessment of what your system actually needs.
Common Lennox Air Duct Cleaning Problems We Solve in South Boston
- Lennox evaporator coils corroded by harbor humidity. The persistent onshore moisture and salt-laden air in South Boston infiltrates through register gaps and duct leaks, accelerating corrosion on coil fins. We pull these coils, clean with foaming agents safe for aluminum-copper construction, and treat with antimicrobial to slow regrowth.
- Blower motor limit switches tripping on high-static retrofit runs. Lennox Elite series air handlers and CBX units were engineered for proper duct sizing. South Boston’s converted triple-deckers force air through chases with too many bends and too little diameter. The motor works harder, the limit switch trips sooner. We measure static pressure, identify restrictions, and clean or reconfigure runs where possible.
- Flex duct degradation in uninsulated chases. Condensation pools in the uninsulated cavities of older triple-deckers, especially near Fort Point Channel where groundwater and harbor moisture converge. The flex connectors on Lennox supply runs soften, sag, and tear. We replace with rated aftermarket flex and seal properly — or recommend rigid conversion where space allows.
- Layered return-air plenum debris from renovation eras. South Boston’s triple-deckers carry history in their walls. We’ve found original coal soot, 1980s plaster dust, fiberglass from multiple gut rehabs, and modern construction debris — all stacked in return plenums that were never cleaned after the forced-air retrofit. Our video inspection finds it. Our HEPA rotary brushing removes it.
- Unsealed gaps at former window-AC slots pulling harbor air. South Boston’s triple-deckers were built with window-unit air conditioning slots. When Lennox forced-air systems were retrofitted, supply registers often landed right where those units once vented. The gaps remain unsealed, pulling moist harbor air directly into your duct system — a contamination entry point you won’t find in inland Boston neighborhoods. We seal these with mastic and metal-backed tape, not duct tape that’ll fail in six months.
Lennox Service in South Boston: What Local Conditions Mean for Your Equipment
Here’s something we learned on West Sixth Street that changed how we approach every South Boston triple-decker. We were cleaning a Jamaica Plain Lennox service G14 system in a converted unit where the supply duct ran through a former closet — standard enough for this neighborhood. The video inspection revealed layered coal soot from the pre-conversion heating era, plaster dust from a 1990s condo gut rehab, and a mouse nest inside the return plenum. Three decades of occupancy, three distinct contamination layers, none of it visible from the registers.
We performed full-system HEPA vacuuming with rotary brushing, then sealed all duct joints with mastic to stop moisture infiltration from the crawlspace below. The homeowner had lived there four years and never knew. That’s the South Boston pattern: forced-air retrofits installed during condo conversions, never cleaned afterward because new owners assumed “new system, clean ducts.” The ducts weren’t new. The chases were original. The debris was archaeological.
This is why we start every South Boston job with video inspection. I’ll show you what’s in there before I tell you what it costs.
Lennox Models & Products We Service in South Boston
We regularly service Lennox in Boston G14 gas furnace series, Lennox Elite series air handlers, Lennox Pulse furnace series, and Lennox CBX air handlers — the units most commonly retrofitted into South Boston’s converted housing stock during the 1990s and 2000s condo booms. These systems are aging into their second and third decades now, which means honest repair-or-replace assessment matters more than ever.
For critical components — blower motors, limit switches, control boards — we source OEM Lennox parts when available. For non-critical items like flex duct, insulation wrap, and register boots, we use quality aftermarket that meets or exceeds spec at better value. We stock common Lennox blower belts, capacitors, and filter sizes for faster South Boston turnaround, and we coordinate with regional distributors for same-day or next-day OEM when needed.
Our sub-services on these systems include video inspection to document condition, evaporator coil cleaning to restore heat transfer efficiency, and duct sealing to stop harbor-air infiltration and improve system static pressure.
Lennox Service Pricing in South Boston
Pricing for Lennox air duct cleaning in South Boston depends on system accessibility, contamination level, and whether we’re dealing with standard ductwork or the retrofitted chases common in triple-decker conversions. Most residential Lennox systems in 02127 fall in these ranges:
- Standard air duct cleaning: $350–$650 for typical single-system residential
- Video inspection with full documentation: $150–$250 (often bundled with cleaning)
- Evaporator coil cleaning: $200–$400 depending on accessibility and corrosion level
- Duct sealing (mastic, tape, register gasket replacement): $400–$900 for full-system work
- Air quality sanitizing with antimicrobial treatment: $150–$300 add-on
Retrofitted triple-decker systems with multiple access points, layered debris, or crawlspace runs may run higher — we quote after inspection, not before. Every estimate is free, and we show you the video evidence before any work begins. Call (877) 517-5646 to schedule — we’ll give you an exact figure after we see what we’re working with.

FAQs — Lennox Air Duct Cleaning in South Boston
Yes. We’ve cleaned Lennox systems routed through former coal chutes, closet conversions, and cut floor-joist chases throughout South Boston. Our Rotobrush and Nikro systems use flexible shafts and reduced-diameter brushes designed for exactly these non-standard configurations. The tight bends actually trap more debris, so they need cleaning more — not less. Call (877) 517-5646 and we’ll assess the access points during your free estimate.
We use OEM Lennox parts for critical components like blower motors, limit switches, and control boards where exact spec matters for safety and warranty preservation. For filters, flex duct, and insulation, we recommend quality aftermarket that performs equivalently at better value. We’re independent — not Lennox-authorized — so we make these calls based on your system’s actual condition, not a manufacturer parts quota.
Almost certainly, and likely more than that. We’ve found layered construction debris in virtually every Winthrop Lennox service triple-decker retrofit we’ve inspected — drywall dust, plaster from earlier eras, fiberglass insulation fragments, and occasionally older heating-system soot. The condo conversion process typically didn’t include duct cleaning afterward. Our video inspection will show you exactly what’s in there before we quote any remediation work.
Rust at register edges in South Boston is common but not “normal” — it’s a symptom. The salt-laden harbor air infiltrates through gaps around registers and duct joints, condensing on cooler metal surfaces and accelerating corrosion. It’s worse in uninsulated chases and near Fort Point Channel where humidity runs highest. We treat the rust, seal the infiltration points with mastic and metal-backed tape, and can apply corrosion inhibitor where appropriate. Left unaddressed, it spreads to ductwork and eventually the furnace cabinet itself.
Carefully, and with the right equipment. Our Nikro and Abatement Technologies systems include portable HEPA vacuums and flexible rotary tools that fit where standard truck-mounted rigs won’t. Thomas Hernandez, our owner and lead technician, has 14 years of experience routing tools through cramped access points — he evaluates each crawlspace for safety and workable angles before starting. Some of the tightest South Boston jobs have yielded the most dramatic before-and-after results. Call (877) 517-5646 to discuss your specific access situation.
