Whole-system duct and dryer vent check with before-and-after photos - you see exactly what came out of your vents
That "$99 whole-house special" is a bait ad - the real number appears once they are in your hallway, or the "clean" is a shop-vac at the register. We photograph the inside of your ducts before and after instead.

AfterLennox Air Duct Cleaning in Columbus, CA | Cardinal Air Duct Cleaning
We provide independent Lennox Columbus Air Duct Cleaning, and the work here looks different from what you’d see in most other cities. Columbus’s split between 1920s bungalows and 1990s suburban builds means Lennox systems here run through wildly different ductwork, often on the same service route. If you own a Lennox system, our crews know its cabinet layout, coil clearances, and return design better than any generalist duct cleaner. Call (737) 727-2314 for a free estimate.
Why Columbus Residents Choose Us for Lennox Service
Cardinal Air Duct Cleaning is an independent Lennox service provider, not an authorized Lennox dealer, and that independence means we tell you what the equipment actually needs rather than what a manufacturer program wants sold. Our owner, Omar Haddad, spent well over a decade cleaning residential and commercial duct systems across Los Angeles County before founding Cardinal, and he’s the one who set the standard: source removal with Rotobrush and Nikro equipment, never vacuum-and-go shortcuts. For Lennox work in Columbus, that means video inspection first, cleaning that reaches the coil and blower, and sealing that actually holds. We’re part of the Relay Home Co. family, founded 2005, and every booking carries a live trackable arrival time, before-and-after photos, and a written price before a single duct is touched.
If you’re in Columbus and the Lennox nameplate is on your furnace or air handler, you want a crew that opens the cabinet and knows what it’s looking at. We do. See our full Lennox sales & service page for the broader picture, or check our Columbus service area reach.
Common Lennox Air Duct Cleaning Problems We Solve in Columbus
Here’s what we actually find when we open up Lennox systems in Columbus homes:
- Undersized return drops on Merit Series and older builder-grade units. Lennox Merit Series and older builder-grade Lennox equipment often ships with return drops sized to the bare minimum. In Columbus’s older Clintonville and Linden bungalows, we open those starved drops and find them packed with dust mat and construction debris, especially plaster dust from pre-1950 renovations. The system was never getting enough return air, so it pulled from wherever it could, including wall cavities and unsealed joints.
- Musty odors from tight coil slabs in Elite and Signature air handlers. Lennox cased evaporator coils in Elite and Signature units have tight cabinet clearances. In humid Columbus summers, the condensate pan stagnates and biological growth forms on the coil and blower wheel. That’s the musty smell you get when the cooling cycle starts. Duct cleaning alone won’t fix it; the coil has to be addressed.
- Variable-speed blowers straining against dirty returns. Lennox high-efficiency variable-speed air handlers are sensitive to static pressure. A partially clogged return or crushed duct run makes the ECM blower ramp against excess resistance. Delivered airflow drops, and unfiltered bypass air gets pulled through unsealed cabinet joints. We see this all over Columbus, especially in 1990s Dublin and Powell subdivisions where flex runs sag over time.
- Healthy Climate MERV 16 filter bypass. Lennox Healthy Climate MERV 16 filters are excellent, but in older cabinets they often sit in a slightly panned return. Fine dust bypasses the filter edges, coats the blower wheel, and works its way into the supply trunk over multiple seasons. Owners think they’re filtering well; the downstream dust tells a different story.
- Collapsed flex runs on supply side. In newer Columbus subdivisions, especially Dublin and Powell builds from the 1990s and 2000s, flex duct gets kinked or crushed in attics and crawlspaces. A Lennox system pushing into a collapsed supply run loses a whole room’s airflow. We find these during video inspection and repair them before cleaning finishes.
Lennox Service in Columbus: What Local Conditions Mean for Your Equipment
Columbus’s housing stock is genuinely split. A 1928 Clintonville bungalow off Indianola Avenue still runs an original gravity-furnace chase, often unlined, often sharing wall cavities with return air. A mile away, a 1990s Dublin subdivision has tightly ducted flex systems designed for a Lennox Elite or Signature air handler. In the same week we’ll clean a legacy unlined return chase packed with drywall dust and a newer system with tight-but-sagged flex runs. That spread of housing stock is not what a Sun Belt or coastal market’s typical Lennox work looks like. It means Lennox duct cleaning here routinely involves legacy chases and modern ducted systems in the same neighborhood, sometimes on the same block. A technician who only knows one type will miss the other. We clean both.
One example from our recent work in Columbus: in a 1928 Clintonville bungalow off Indianola Avenue, our techs video-inspected a Lennox Merit Series gas furnace with a MERV 10 Healthy Climate cabinet and found the original unlined return chase packed with drywall dust and a collapsed flex supply to a rear bedroom. We also offer Dryer Vent Cleaning - Columbus for homes with similar vintage infrastructure. We cleaned and vacuumed the chase, repaired the crushed flex run, sealed the plenum and Lennox cabinet joints with mastic, treated the evaporator coil, and the homeowner reported both better cooling upstairs and noticeably less dust settling on furniture.
Lennox Models & Products We Service in Columbus
We clean and seal ductwork on the full Lennox line: Merit Series, Elite Series, and Dave Lennox Signature Collection. Each has different cabinet realities. Merit units are the most common in Columbus starter homes and rentals, and they’re the ones most likely to have undersized returns. Elite and Signature air handlers run tighter tolerances, so coil cleaning and static pressure matter more.
For filters, we use OEM Lennox MERV 10 and MERV 16 Healthy Climate media filters where the cabinet was designed for them. OEM matters there because filter fit and cabinet gaskets have to seal, and aftermarket media often doesn’t. For the ductwork itself, high-quality aftermarket flex and metal duct, mastic, and fittings are the right call. If we find a Lennox coil or heat exchanger that’s corroded or cracked beyond cleaning or safe repair, we say so plainly: cleaning the ducts will not fix a failing component. That’s a conversation for an HVAC contractor about equipment replacement, not a reason to upsell you on duct work.
Lennox Service Pricing in Columbus
Most standard Lennox air duct cleaning jobs in Columbus run $350 – $600 for a typical home, depending on system size, number of returns, and how much access the ductwork allows. Evaporator coil cleaning typically adds $150 – $300. Video inspection is included with our cleaning, not billed as a separate line item. What drives the cost on a Lennox system specifically is the cabinet work: tight coil clearances, ECM blower access, and the sealing steps that keep bypass air out of a new clean.
Every estimate is written before work starts. That price is the price. Call (737) 727-2314 and Omar will walk you through what your Lennox system likely needs and what it will cost, free.

FAQs – Lennox Air Duct Cleaning in Columbus
No. A healthy climate slot is sized for a 4-inch or 5-inch media filter, and a 1-inch filter will not seal the cabinet, meaning air bypasses the filter entirely and the blower wheel gets coated with dust. If you want a 1-inch filter setup, we can tell you whether your specific Merit cabinet can be adapted, but the correct fix is usually the OEM Lennox Healthy Climate filter in the media cabinet.
It needs a technician who understands static pressure. Variable-speed ECM blowers ramp against resistance, so a clogged return or crushed duct run makes the blower work harder than it should, which reduces delivered airflow and can pull unfiltered bypass air through unsealed cabinet joints. Our cleaning process includes checking and sealing the return side and correcting collapsed runs before we finish, not just vacuuming out visible dust. Call (737) 727-2314 if your Lennox variable-speed system is short on airflow.
Because the smell is usually coming from the evaporator coil, not the ducts. Lennox cased coils sit in tight cabinets, and humid Columbus summers keep the condensate pan damp. Biological growth on the coil and blower wheel releases musty odor into the supply air during cooling cycles. Duct cleaning removes debris from the ducts, but if the coil is growing, the smell returns. That’s why we treat the coil as part of the job, not an add-on. Call (737) 727-2314 for a full picture.
Yes. We’re an independent provider, not an authorized Lennox dealer, but cleaning and sealing ductwork and cabinets does not void a Lennox warranty. What would void a warranty is leaving a failing component in place, or using the wrong filter media that lets bypass air erode the blower. We use OEM Lennox Healthy Climate filters where the cabinet calls for them, and our sealing work is mastic-based, not foam that degrades.
The video inspection shows you exactly what’s inside your ducts before and after cleaning: dust mat accumulation, construction debris, collapsed flex runs, unsealed joints, and filter bypass evidence. You see the same footage our techs see, and you get before-and-after photo documentation with every job. It’s the difference between trusting a stranger’s word and seeing the work. Call (737) 727-2314 to book an inspection and cleaning.
