Why Columbus Residents Choose Us for Lennox Service
Paul Torres grew up on Columbus’s Near East Side, a few blocks from Franklin Park, and spent his early career in the trades around central Ohio after completing HVAC coursework at Columbus State Community College. He shifted focus specifically to duct systems — the part most contractors rush through or skip entirely — and for eight years now he’s run every job at Legacy Air Duct Cleaning himself. He inspects, operates the Rotobrush and Nikro mechanical agitation systems, and speaks directly with homeowners afterward. Nearly 1,000 customers have reviewed that approach at 4.7 stars.
That matters for Lennox owners because these systems have specific airflow personalities. The Merit Series ML180 runs a higher static blower than some competitors, which exaggerates any flex-duct sagging. The CBX air handlers have shallow coil pans that trap debris in Columbus’s humid summers. We’ve cleaned enough of them in Hilliard, Dublin, and Clintonville to know where the problems hide before we open the access panel. Paul shows up personally as lead technician on your job — not a rotating crew — and if he wouldn’t put it in his own house, he won’t recommend it for yours.
Common Lennox Air Duct Cleaning Problems We Solve in Columbus
- Flex-duct collapse in post-1990 suburban homes. Lennox’s high-static blowers — especially on Merit Series units — pull hard enough to collapse sagging flex duct in attics across Hilliard, Dublin, and Grove City. The original construction dust and insulation fibers from 1990s–2010s builder-grade installs never got cleaned out, and now they’re trapped in kinked runs where standard vacuum pressure can’t reach. We cut in access points, repair the sag with proper support straps, and agitate the debris with Nikro mechanical brushes before extraction.
- Mold in CBX coil cabinets during Columbus summers. July dew points in the upper 60s°F mean the coil pan in a Lennox CBX air handler stays wet for hours after shutdown. The pan’s shallow slope and narrow drain trap collect pollen and skin cells — perfect mold food. By late August, when ragweed pollen spikes across Franklin County, that microbial growth recirculates a musty, well water-like odor through every supply register. We disassemble the plenum, clean the pan and coils with IAQ-grade treatments, and verify drainage slope before reassembly.
- Compacted debris in oversized gravity-conversion trunks. In Linden and Hilltop, we regularly encounter 1950s–60s ranches where a forced-air Lennox conversion was grafted onto 18-inch-plus rectangular trunk lines from the coal-heat era. Decades of soot, rodent debris, and compacted particulate settle in low-velocity runs. Standard negative-pressure HEPA cleaning fails here — the ducts are too large to pressurize fully. We switch to extended manual agitation with compressed air whips and direct-contact vacuum heads, adding job time that flat-rate pricing rarely accounts for.
- Filter grille staining in tight New Albany homes. Lennox systems with undersized return paths pull carpet fibers and ultrafine dust against the filter grille, leaving permanent dark staining. The EL180E and SL280V variable-speed models exacerbate this when running continuously on low fan speed. We clean the return trunk, upsize the filter media where possible, and seal duct leaks that draw attic or crawl space debris into the return stream.
- Post-construction dust loading after Dublin remodels. Lennox flex duct in attics traps drywall dust for years after a basement finish or kitchen renovation. The ML14XC1 and EL16XC1 condensers run long cooling cycles in Columbus’s humid summers, keeping the blower active and recirculating that debris. We video-inspect before and after so you see the difference — not just take our word for it.
Lennox Service in Columbus: What Local Conditions Mean for Your Equipment
Many Columbus homes built before 1970 still have original Lennox gravity-fed trunk-and-branch systems converted to forced air in the 1950s–60s — especially in the Clintonville neighborhood — where the ductwork was never designed for modern high-static pressurization. The 20-inch rectangular mains on North Star Road and surrounding streets carry persistent air leaks at every joint, and decades of debris recirculate through gaps that standard duct cleaning cannot resolve without manual sealing of every accessible connection. We serviced a Lennox Merit ML180 furnace in a 1955 ranch on North Star Road in Clintonville. The system had a converted gravity trunk with decades of soot and rodent debris compacted into a 20-inch rectangular main. Our tech spent four hours with a compressed air whip and HEPA vacuum manually agitating each branch because the flex-jumper connections were too irregular for standard negative-pressure pull. Post-inspection video showed clear runs and restored airflow. That kind of job doesn’t fit a coupon special. It fits a technician who’s done enough of them to price honestly and work until it’s actually clean.
Lennox Models & Products We Service in Columbus
We clean across the full Lennox residential lineup: Merit Series furnaces and condensers (ML180, ML14XC1), Elite Series variable-speed systems (EL180E, EL16XC1), Signature Series modulating equipment (SL280V, SL18XC1), and CBX air handler series. Our Rotobrush and Nikro systems adapt to each — the Merit Series’ fixed-speed blower responds well to standard agitation, while the Signature Series’ modulating airflow requires careful static-pressure monitoring during cleaning to avoid tripping fault codes.
We stock OEM-spec coil pans, drain trap assemblies, and flex-duct transition fittings locally for Columbus jobs, but we’re clear about our position: we’re independent, not Lennox-authorized. When your EL16XC1 needs a part we don’t carry, we source factory-equivalent components from our regular suppliers rather than marking up through a dealer network. One company for your entire duct system — cleaning, sealing, repair, and sanitizing — with Paul Torres running the equipment on every call.
Lennox Service Pricing in Columbus
Complete Lennox air duct cleaning in Columbus typically ranges from $350 to $650 for residential systems, depending on access difficulty, duct material, and whether we find conditions requiring repair or extended agitation time. A standard flex-duct home in Dublin or New Albany with straightforward attic access falls toward the lower end. Converted gravity systems in Linden, Hilltop, or Clintonville — with oversized trunks and irregular branch connections — run higher due to manual labor time.
Every estimate includes pre- and post-cleaning video inspection, register and return grille cleaning, and static-pressure readings on the Lennox unit. We don’t quote over the phone for jobs involving converted gravity systems or known sagging flex duct — we need eyes on the actual configuration. Call (844) 945-2561 to schedule a free, no-obligation estimate. Paul Torres handles the inspection himself.

FAQs — Lennox Air Duct Cleaning in Columbus
It’s usually both. The CBX coil pan’s shallow slope traps water and debris in Columbus’s humid summers, breeding mold that recirculates through the supply plenum and into duct runs. We disassemble the cabinet, clean the pan and coils, verify drainage, and treat accessible ductwork. Call (844) 945-2561 — we’ll confirm with a video inspection before any work starts.
Standard negative-pressure cleaning alone won’t fully clear 18-inch-plus gravity-conversion trunks — the volume’s too large to pressurize effectively. We add manual agitation with compressed air whips and direct-contact vacuum heads, extending dwell time until debris releases. We’ve done this exact work in Linden and Hilltop ranches. The job takes longer than a standard cleaning, and we price it accordingly after inspection.
Replacement is sometimes necessary, but not always. If the flex is kinked, torn, or the inner liner is delaminating, we recommend replacement with properly supported new flex or rigid duct. If the sag is minor and the liner’s intact, we can restore support, agitate out construction debris with our Nikro system, and seal connections. Paul Torres will show you the video and give you a straight assessment — no pressure either way.
Yes, but it’s usually a symptom, not the root problem. Staining indicates excessive return-side leakage pulling carpet fibers and fine dust against the grille, or an undersized return path forcing high face velocity. We clean the return trunk, seal accessible leaks, and evaluate whether the return path needs modification. For exact pricing on your Lennox system, call (844) 945-2561 — estimates are free.
A “standard” cleaning that only hooks a vacuum to the trunk and runs for an hour often dislodges debris without fully extracting it — especially in Lennox systems with high-static blowers that redistribute loosened material before it reaches the collection point. We use mechanical agitation (Rotobrush or Nikro) with concurrent vacuum extraction, and we seal the system during cleaning to prevent redistribution. If you’ve had a bad experience elsewhere, we’ll show you our pre/post video protocol so you know exactly what you’re paying for.
