Lennox Air Duct Cleaning in Gahanna, OH | Legacy Air Duct Cleaning Columbus

Why Gahanna Residents Choose Us for Lennox Service
Paul Torres grew up on Columbus’s Near East Side, a few blocks from Franklin Park, and after completing his HVAC coursework at Columbus State Community College, he deliberately narrowed his focus to duct systems—the component most contractors rush past. For over eight years, he’s run Legacy Air Duct Cleaning himself, doing the inspections, running the Rotobrush equipment, and talking directly to every homeowner after the job is done. In Gahanna, that means you’re not getting a franchise crew with a weekend training certificate. You’re getting Paul on your property, examining your Lennox blower assembly, checking your flex-duct sags, and telling you straight what needs cleaning now versus what can wait.
We’ve built our reputation on nearly 1,000 verified customer reviews—935 at a 4.7-star rating—because we name the actual equipment we use and the actual condition we find. Our Rotobrush and Nikro mechanical agitation systems are the same platforms industrial IAQ contractors deploy, not the consumer-grade vacuums some generalist handymen haul around. For Lennox owners in Gahanna, that translates to proper handling of your Merit, Elite, or Dave Lennox Signature Collection system’s specific duct geometry without manufacturer-affiliation constraints.
One company handles your entire duct system: cleaning, sanitizing, dryer vent service, and duct repair and sealing. No separate vendors, no finger-pointing.
Common Lennox Air Duct Cleaning Problems We Solve in Gahanna
- Degraded fiberglass duct liner shedding particles. Gahanna’s ranch and two-story colonial homes from the 1970s–1990s boom often still run original Lennox forced-air systems with fiberglass-lined metal ductwork. That interior lining degrades after decades and actively sheds particles into your circulated air. We clean the debris and, where needed, encapsulate the liner with food-grade sealant to stop the shedding.
- Duct condensation and mold growth from oversized AC units. Builder-grade Lennox Merit Series installs in Gahanna frequently short-cycle because they’re oversized for the ductwork, especially in humid summer conditions near Big Walnut Creek. The unit kicks off before dehumidifying, leaving moisture inside ducts that feeds microbial growth. Our evaporator coil cleaning and duct sanitizing address the symptom; our video inspection identifies the underlying sizing mismatch to discuss with your HVAC contractor.
- Jet-exhaust particulates clogging filters and coating coils. Subdivisions under John Glenn Columbus International Airport’s eastern approach paths see Lennox air filters load up faster and evaporator coils develop a gray film unlike typical household dust. This particulate infiltration reduces system efficiency and recirculates fine particles your family breathes. We pull this material out with mechanical agitation, then show you the difference on video.
- Return duct leaks overworking Lennox blower motors. Older postwar homes near Olde Gahanna were retrofit with ductwork not properly sized or sealed for modern Lennox equipment. Gaps and flex-duct sags create return leaks that force blower motors to overwork and overheat, frequently misdiagnosed as motor failure. Our duct sealing service restores proper static pressure and extends motor life.
- Trapped debris in flex-duct sags. Gahanna’s 1990s colonials with retrofit flex runs often develop low points where lint, dander, and that distinctive gray airport particulate collect. Our Nikro systems agitate these deposits loose and extract them fully, something consumer-grade equipment can’t manage in sagging flex duct.
Lennox Service in Gahanna: What Local Conditions Mean for Your Equipment
Homes in Gahanna’s Chapel Glen and Porthmouth neighborhoods, directly under the John Glenn Airport’s eastern departure corridor, accumulate a distinct gray, soot-like duct debris unseen in suburbs farther from the flight paths. We’ve pulled this material from Lennox systems on Havenswood Road and throughout the 43230 ZIP code. It requires specialized cleaning protocols to fully remove—standard residential duct cleaning, designed for ordinary household dust, leaves this particulate behind. The combination of this airport-proximity factor with Big Walnut Creek’s moisture influence creates an unusually high dual exposure: particulate fouling from jet exhaust plus microbial growth risk from humidity. Your Lennox system, whether a 30-year-old Merit or a new Dave Lennox Signature Collection unit, is working against both simultaneously. That’s why our Gahanna protocol includes video inspection before and after, mechanical agitation with Rotobrush and Nikro systems, and targeted duct sealing where the airport particulate has forced its way in through gaps.
We serviced a 1989 Lennox Merit Series system in a Chapel Glen ranch home on Havenswood Road. The return plenum and supply registers showed heavy gray particulate consistent with jet exhaust. Our video inspection revealed degraded fiberglass liner shedding into the airstream. We cleaned the entire duct system and sealed the liner with a food-grade encapsulant, restoring airflow and eliminating the sooty discharge from the registers.
Lennox Models & Products We Service in Gahanna
We work on the full Lennox residential lineup: Merit Series, Elite Series, Dave Lennox Signature Collection including the SL280V and SL25XPV, and the X Series CBX32MV. Our parts approach is straightforward: OEM Lennox components for primary replacements—blowers, motors, coils—because fit and efficiency matter. High-quality aftermarket parts for ancillary items like flex duct and mastic sealants, where manufacturer branding doesn’t affect performance. We stock common Lennox blower assemblies and coil configurations locally for fast Gahanna turnaround, and our independence from the manufacturer means we’re not pushing factory service plans or constrained by authorized-dealer territories. If I wouldn’t put it in my own house, I won’t recommend it for yours.
Lennox Service Pricing in Gahanna
Most complete Lennox air duct cleaning jobs in Gahanna fall between $380 and $620 for a typical 1,500–2,500 square foot home, depending on system accessibility, duct material type, and contamination level. Evaporator coil cleaning adds $180–$280; duct sealing runs $450–$850 based on linear footage and access difficulty. Video inspection is included with every full cleaning—we show you what we’re seeing, not just tell you.
Homes near the airport with heavy gray particulate accumulation, or older properties with degraded fiberglass liner requiring encapsulation, trend toward the upper end of these ranges. We assess every system in person before quoting. Our free estimate includes a full walkthrough of your Lennox equipment, register count, duct material identification, and contamination level assessment. Call (844) 945-2561 to schedule—estimates are free, and we’ll give you an exact number after seeing your system.

FAQs — Lennox Air Duct Cleaning in Gahanna
Often, yes. Many Gahanna homes built during the 1970s–1990s suburban boom were originally fitted with smaller-capacity furnaces, and the ductwork was sized accordingly. When homeowners later upgrade to higher-BTU Lennox units, the existing ducts can’t move enough air, creating pressure imbalances and accelerated debris accumulation. We identify this mismatch during our video inspection and recommend appropriate solutions. Call (844) 945-2561 for a free assessment of your system’s airflow dynamics.
Yes, if the odor originates in the duct system or evaporator coil. The moisture influence from Big Walnut Creek, combined with short-cycling from oversized Lennox AC units common in this area, creates condensation conditions that feed microbial growth. Our evaporator coil cleaning and duct sanitizing eliminate the biological source of musty odors. If the smell persists after cleaning, we’ll tell you straight—it may indicate a drainage issue or duct leak requiring repair beyond cleaning scope. Call (844) 945-2561 and we’ll diagnose the source.
Homes under John Glenn Columbus International Airport’s flight paths, particularly in Chapel Glen and Porthmouth, typically need cleaning every 2–3 years rather than the standard 3–5 year interval. The elevated fine-particulate load from jet exhaust infiltrates filters and ductwork faster than in suburbs like New Albany or Westerville. We monitor this with our pre-cleaning video inspection and can show you exactly how much debris has accumulated since your last service. Call (844) 945-2561 to check whether your system is due.
Absolutely. The gray, soot-like particulate we find in airport-proximate Gahanna homes is visible on camera and distinct from ordinary household dust. We record before-and-after footage so you can see where this material originated and confirm its complete removal. Paul Torres reviews this footage with you personally after the job. Call (844) 945-2561 to schedule an inspection if you’re seeing this discharge around your registers.
Yes. Many 1990s colonials in Gahanna developed flex-duct sags during original installation or subsequent settling, creating debris traps and return leaks that overwork Lennox blower motors. Our duct sealing service addresses both the sagging runs and the gaps at connections, restoring proper static pressure. We use mastic sealants and mechanical supports, not tape that degrades. Call (844) 945-2561 for a free evaluation of your flex duct condition.
