Why Belmont Residents Choose Us for Lennox Service
We’ve spent 14 years specializing in one thing: air duct and HVAC systems. Nothing else. That focus matters when your Lennox unit is connected to ductwork that was never part of the original house plan.
Thomas Hernandez grew up in Lowell’s Centralville neighborhood, picked up his mechanical foundation at Middlesex Community College, and has built Titan Air Duct Cleaning on a straightforward principle — “I’ll show you what’s in there before I tell you what it costs.” He shows up as both the owner and the technician doing the work. Not a subcontracted crew. Not a dispatcher sending anonymous techs.
Our equipment roster tells the rest of the story. We run Rotobrush, Nikro, and Abatement Technologies systems — the same platforms used in commercial and remediation-grade jobs, applied to residential work. When we clean a Lennox system in Belmont, we’re not running a shop-vac on a stick. We’re using video inspection to map debris in kinked flex runs, then extracting it with tools built for real duct geometry.
389 customers have reviewed us, averaging 4.7 stars. That’s not a handful of cherry-picked testimonials — it’s a track record across thousands of jobs, including hundreds of Lennox units in retrofitted Massachusetts homes.
Common Lennox Air Duct Cleaning Problems We Solve in Belmont
- Mold growth in Merit Series evaporator coil drain pans. The ML14XC1 and ML180UH are workhorses, but their drain pans back up when flex ducts routed through humid crawlspaces trap condensation. Belmont’s long heating season followed by muggy summers creates exactly this cycle. We clean the pan, clear the condensate line, and inspect surrounding duct insulation for saturation.
- Heat exchanger rust on older Elite gas furnaces. The EL180 and EL280 develop corrosion when restricted return ducts in retrofitted closets cause overheating. In Belmont’s 1920s colonials near Waverley Square, we’ve found furnaces shoehorned under staircases with 6-inch clearances — nowhere near adequate for proper combustion airflow. This isn’t just an efficiency problem; it’s a carbon monoxide risk. We flag it immediately.
- Blower motor bearing wear on Signature Series units. The SLP99’s variable-speed blower is precision equipment, but lint buildup in tight attic chases — common in Belmont Capes with retrofitted ducting — forces it to work harder. Noise and airflow drop follow. Our cleaning includes the blower assembly and the full return path, not just the supply registers.
- Flex duct kinking at tight basement bends. Lennox air handlers in Belmont’s 1980s–1990s retrofits often sit against basement joists with flex duct making sharp 90-degree turns through minimal clearance. Airflow restriction leads to freeze-ups in AC mode and overheating in heat mode. We don’t just clean around the kink — we reroute and seal with mastic when the geometry allows.
- Debris trapping in non-standard chase configurations. Belmont homes with original steam radiators converted to forced air often have ductwork stuffed through former chimney flues or closet chases never designed for airflow. These dead zones accumulate decades of dust, construction debris, and — in one case we still talk about — a 1960s newspaper wad that had petrified into a airflow dam. Our video inspection finds what standard cleaning misses.
Lennox Service in Belmont: What Local Conditions Mean for Your Equipment
Belmont’s historic districts, such as Belmont Hill, have many homes with original steam radiators and retrofitted forced-air ductwork that often passes through uninsulated basement ceilings or attics, creating condensation pockets that promote mold. Lennox units connected to such ducting require careful evaluation of insulation and sealing during cleaning.
Here’s what that means in practice. A Lennox in Newton ML180UH furnace in a Belmont Hill Colonial Revival might be performing perfectly by the unit’s own diagnostics, but if its supply trunk runs through an unheated attic with R-4 insulation slapped on in 1987, that warm air hits cold surfaces and condenses. The moisture doesn’t damage the furnace directly — it damages the duct system, which then feeds mold spores and degraded insulation particles back through the Lennox blower and into your living space. We’ve opened duct seams in these homes and found insulation facing that had turned to black mush.
Our cleaning protocol for Belmont Lennox systems includes thermal imaging of accessible duct runs to identify these condensation points. We don’t just vacuum debris; we document where the system is actively generating new contamination. If your Lennox unit is relatively new but your air quality stays poor, the problem is almost certainly in the retrofit ductwork — not the equipment.
Lennox Models & Products We Service in Belmont
We work on the full Lennox residential lineup, with particular depth on the units most common in Belmont’s retrofitted homes:
- Merit Series: ML14XC1 air conditioners, ML180UH gas furnaces — the entry-level workhorses often installed during 1990s–2000s conversions from boiler heat.
- Elite Series: EL16XC1, EL280UH — mid-efficiency units with more sophisticated blower controls, frequently found in larger Belmont Hill and Belmont Center homes where owners wanted better zoning.
- Signature Series: SL18XC1, SLP99UH — high-efficiency condensing furnaces and two-stage AC units, increasingly common in renovation projects where owners kept the vintage exterior but modernized mechanical systems.
For critical components — blower motors, coil drain pans, control boards — we prioritize genuine Lennox OEM parts. The fit matters in tight retrofit spaces where aftermarket tolerances can mean the difference between a clean install and a return call. For duct sealing and insulation, we use quality aftermarket materials that meet or exceed OEM thermal and fire-resistance specs. We’ll repair a 2010 ML180UH if duct cleaning and sealing can restore its performance; we’ll recommend replacement for any unit over 20 years with a corroded heat exchanger, regardless of brand.
Lennox Service Pricing in Belmont
Our Belmont Lennox air duct cleaning pricing reflects the additional time retrofitted systems require:
| Service | Price Range |
|---|---|
| Standard air duct cleaning (up to 10 vents) | $350–$450 |
| Deep cleaning with video inspection | $450–$550 |
| Full system cleaning + sanitizing (Honeywell/Aprilaire/Guardsman) | $550–$650 |
| Flex duct repair/re-routing (per section) | $150–$300 |
| Dryer vent cleaning (add-on) | $100–$150 |
What drives cost: accessibility of your duct runs, amount of debris buildup, whether we find damage requiring repair or sealing, and whether your Lennox unit needs blower assembly cleaning beyond standard ductwork. Every estimate starts with a physical inspection — we don’t quote over the phone for Belmont’s non-standard systems. Call (877) 517-5646 to schedule; estimates are free, and Thomas will walk you through what he finds before any work begins.

FAQs — Lennox Air Duct Cleaning in Belmont
Yes — we access most systems through the supply and return registers, not the furnace itself. For Belmont’s many closet-installed Lennox units, we use portable Rotobrush and Nikro equipment that fits through standard register openings. If we need furnace access for blower cleaning, we’ll discuss that separately after inspection. Call (877) 517-5646 to schedule a look — estimates are free.
No — we match the tool to the duct. Belmont’s retrofitted flex duct and tight metal chases require different approaches than purpose-built rigid trunk systems. We use smaller-diameter brushes and pneumatic whips for kinked flex runs, and video inspection to verify debris removal in sections we can’t physically see. The goal is thorough cleaning without damaging already-stressed ductwork.
That white powder is likely corrosion byproduct from a compromised heat exchanger — and yes, it can indicate carbon monoxide risk. Restricted airflow from clogged or poorly designed return ducts (common in Belmont retrofits) causes overheating that accelerates metal fatigue. We don’t clean around this; we flag it for immediate evaluation and recommend a licensed HVAC contractor for heat exchanger inspection. Do not operate the furnace until it’s checked.
Often yes — if the efficiency loss is from airflow restriction, not equipment degradation. A 2010 ML180UH in good mechanical condition can lose 15–25% effective output when ducts are clogged or kinked. We’ve restored noticeable performance in Belmont homes where flex duct had partially collapsed in joist bays. We’ll measure static pressure before and after to document improvement. Call (877) 517-5646 for an assessment — we’ll tell you honestly if cleaning will help or if you’re looking at a larger issue.
Our equipment is HEPA-contained — debris is captured at the source, not blown through your home. The SLP99’s sealed combustion design actually helps here; we can often isolate the furnace cabinet during cleaning. For finished basements in Belmont, we also lay protective covering and seal registers not actively being cleaned. Your living areas stay clean.
