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.

AfterFast, Reliable Air Duct Cleaning Across Knoxville
Air duct cleaning in Knoxville typically runs between $450 and $900 for a full system on a 2,000-square-foot home, and the work usually takes four to six hours. That’s the honest range before anyone sets foot in your house. We know because we’ve documented thousands of Knoxville systems since 2013, and we put the price in writing before a single panel comes off. If that’s what you’re after, call (806) 606-6902 and you’ll have a number today, not after a salesman walks your attic.
Knoxville is a specific place with specific duct problems. The valley holds moisture and pollen against the city like a lid on a pot. Homes built in the TVA’s Gold Medallion era pushed forced-air electric heat into most of Bearden, Fountain City, and West Knoxville, and that means miles of aging fiberglass duct board running through humid crawlspaces. Nobody in Phoenix deals with what we pull out of a 1960s Holston Hills return line. Our Air Duct Cleaning team works those neighborhoods every week, and we bring equipment sized for the way Knoxville homes were actually built.
Why CleanRun Air Duct Cleaning Is Knoxville’s Preferred Air Duct Cleaning Company
We’re not the cheapest duct cleaning outfit in Knoxville, and we’re not trying to be. We’re the one that hands you a written price before work starts, then photographs every duct run before and after so you can see what you paid for. That combination matters more in this city than most, because Knoxville’s humidity means the difference between a visible clean and a shop-vac pass is obvious on camera. Tomas Reyes, our owner, built the entire operating standard around that evidence-first logic. Under Haven Standard Clause 1, every Knoxville job gets a written scope and price before tools come off the truck.
We carry trade-recognized equipment from Rotobrush, Nikro, and Abatement Technologies. Not because the names impress, but because a HEPA-filtered negative-pressure extraction unit is the only way to safely remove degraded fiberglass duct board from a 1960s Fountain City ranch without blowing glass fibers into the living room. Our crews are background-checked, uniformed, and identified by name before they walk up your drive. The photo record they deliver at the end is yours to keep, not a marketing afterthought.
We also answer the phone. Every call to (806) 606-6902 goes to a live person, day or night. Scheduling for Knoxville is coordinated from our Memphis office, and local crews run Knoxville jobs daily. You won’t get a call center script. You’ll get a time window and a written confirmation.
Our Air Duct Cleaning Services in Knoxville
Residential Duct Cleaning
We clean the full duct system in Knoxville homes: supply runs, return runs, the plenum box where they meet, and the registers at each end. Older ranch homes in Bearden and Fountain City often have original fiberglass duct board from the 1960s or 70s, and those need a gentler cleaning method than sheet metal. We set negative pressure at the plenum and work each run with HEPA-filtered extraction so debris doesn’t get stirred into living spaces.
Commercial Duct Cleaning
Knoxville offices, medical suites, and retail spaces along Kingston Pike and the downtown corridor get the same written-price commitment as our residential work. Commercial systems here tend to run longer hours and pull in more exterior particulate from the valley’s trapped air masses. We document everything the same way: before and after photos inside every duct run, delivered with the invoice.
Supply Duct Cleaning
Supply runs in Knoxville crawlspaces are the most common place we find crushed or disconnected flex duct, especially in older neighborhoods where clay soil settles. A supply run that’s pulling 40 percent of its air from the crawlspace isn’t a cleaning problem, it’s a sealing problem. We clean the run and report what the camera shows: crushed sections, gaps at the collar, or liner failure. Then we quote the repair separately and in writing.
Return Duct Cleaning
Return ducts are what feed your blower, and in Knoxville’s humidity they collect a film of dust and biological growth that goes straight through the system. We open the return plenum, photograph what’s inside, and clean the full path back to the filter. If the filter slot itself is pulling bypass air around the edges, we show you that too.

BeforeAfterTrusted Brands We Service in Knoxville
We work on systems built around Honeywell, Aprilaire, and Guardsman components, and our extraction and inspection equipment comes from Rotobrush, Nikro, and Abatement Technologies. That matters because Knoxville’s older duct systems weren’t built for modern filter restrictions, and a technician who only knows one brand won’t recognize the airflow signatures we see daily. We keep the consumables stocked for the equipment Knoxville homes actually have, which means we’re not running to Memphis for a part mid-job.
Common Air Duct Cleaning Problems We See in Knoxville Homes
- Crumbled fiberglass duct board. The valley humidity works on the interior liner of 1950s through 1980s duct board until it softens and sheds glass fibers. From the outside, the duct looks fine. From the inside, the camera shows the liner flaking away. This is the single most common issue we find in Bearden and Fountain City ranch homes.
- Crushed or disconnected flex duct in crawlspaces. Settling clay soil under older Knoxville neighborhoods shifts crawlspace piers and support framing over decades. Flex runs get pinched under the beam they were once strapped to, or the collar at the plenum pulls loose. The register goes weak, and the fix isn’t cleaning, it’s reseating and sealing.
- Moisture-driven mold on uninsulated ductwork. Knoxville summer humidity regularly pushes crawlspace air past dew point. Sheet metal and flex duct surfaces inside those spaces collect condensation, and where there’s condensation and dust, there’s mold. A cleaning can remove the growth, but until the duct is sealed or the crawlspace is conditioned, it’s a rehearsal, not a remedy.
- Restricted airflow from decades of filter bypass. Many Knoxville homes have filter slots that don’t actually seal. Air runs around the filter instead of through it, dust loads the blower and coil, and the homeowner changes filters monthly without ever seeing a difference. We measure static pressure and photograph the filter slot seal before we call a system clean.

A full residential duct cleaning in Knoxville runs $450 to $900 depending on home size and access. A smaller 2-bedroom in Fountain City with a crawlspace might land at $450.

FAQs - Air Duct Cleaning in Knoxville
The most common reason is degraded fiberglass duct board that’s shedding liner material from the inside, plus return-air bypass at the filter slot pulling dirty crawlspace air into the system. We show you the camera feed from inside your return plenum, and if the liner is failing, cleaning alone won’t fix it. Call (806) 606-6902 and we’ll document what’s actually in your ducts before you pay for another clean.
We stop and photograph the crushed run, show it to you on camera, and quote the repair separately in writing. We don’t clean past a crushed run and call the job done. You get the cleaning, the evidence, and a number for the fix if you want it same visit. The real problem in Holston Hills is settlement from clay soil, and the fix is reseating and resealing the run, not more vacuum time.
Most mold on duct interiors can be cleaned with HEPA-filtered negative pressure and antimicrobial treatment, but the source of the moisture has to be found or it returns. In Knoxville that’s usually an uninsulated crawlspace duct sweating through the summer. We clean first, then we tell you what the sealing repair costs so you can decide if you want the problem gone or just cleaned up for a year.
Every three to five years for most Knoxville homes, but if you live in an older ranch with original duct board in Bearden or Fountain City, you likely need a video inspection before you schedule a clean. The bowl geography of the Tennessee Valley means your ducts collect pollen and mold spore debris from the Smokies faster than a house in Nashville or Memphis. Call (806) 606-6902 and we’ll tell you what your system actually needs based on what the camera shows.
That’s usually a crushed or disconnected supply run in the crawlspace or an interior wall chase, not a cleaning issue. The air is going somewhere, just not to that register. We run a camera through the supply branch and show you where the air is actually going. If it’s a crushed run, we quote the repair. If it’s a design flaw from the original build, we tell you that too.
What Knoxville’s Valley Actually Does to Your Ductwork
Knoxville sits in a bowl. The Great Smoky Mountains ring the valley and hold a humid, pollen-heavy air mass over the city for weeks at a time, spring and fall. The same geography that makes East Tennessee one of the most biodiverse places in North America also makes it one of the most punishing on residential ductwork. Pollen from the oak and mixed hardwood forests loads HVAC filters and duct interiors faster here than in any flatland city in the region. Summer humidity pushes uninsulated crawlspace duct surfaces past dew point, and that’s when mold starts. No generic duct cleaning article tells you that, because the person who wrote it probably never crawled under a Gold Medallion ranch in Fountain City and watched a fiberglass liner crumble on contact.
We have. In a 1960s Gold Medallion ranch in Fountain City, our tech pulled a return grille and found the fiberglass duct board liner so softened by decades of valley humidity that it crumbled on contact, releasing glass fibers into the return stream. We set negative pressure immediately, ran HEPA filtration during the entire extraction, then sealed the liner and replaced a crushed flex run under the crawlspace in the same visit. The homeowner had called it ‘just dirty ducts.’ The real fix was sealing and liner repair, documented before and after with photos you’d recognize as your own house.
That’s the work. That’s what you’re actually paying for in Knoxville. If you want a company that will hand you a written price, crawl under your house, photograph every duct run before and after, and stand behind the result in writing for 365 days, call (806) 606-6902. If you’ve got a competitor’s estimate, bring it. We’ll put our number next to it, in writing, and you can decide. No pressure, no urgency theatre. Just evidence.
