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.

AfterAir Duct Cleaning Company in Knoxville, TN
Air duct cleaning in Knoxville typically runs $350 – $650 for a whole-home system, with most jobs completed in a single visit. What drives the real cost is the local environment: heavy spring pollen from the Great Smoky Mountains, fall leaf-mold spores, and humidity that turns ductwork in older homes into collection points for biological debris. We’re Hollis Air Duct Cleaning, part of the Garrison Partners family, and we’ve built our Knoxville work around these conditions. Our crews use Rotobrush rotary systems and Nikro negative-air machines to remove what the Tennessee Valley puts into your ducts, and every job starts with a written price that doesn’t change. Call (361) 326-5060 for a free estimate.
Why Knoxville Homes Are Different
Knoxville sits in a humid subtropical pocket where the Tennessee River valley meets the Southern Appalachians. That geography matters for your ducts. Summers bring sustained humidity above 70 percent, and winters stay mild enough that mold never really goes dormant inside ductwork. The surrounding forests, especially the oak and hickory canopy that shades neighborhoods like Sequoyah Hills and Island Home, pump pollen and mold spores into HVAC intakes from March through November.
The housing stock here tells its own story. Pre-1920 mill houses and bungalows in Old North Knoxville and Fourth and Gill often run on original sheet metal ductwork with failing seams and no sealing. Post-war ranch homes in Fountain City and West Hills frequently have flexible duct runs installed in the 1980s and 1990s, now brittle and accumulating debris where sags create low points. We’ve opened ducts in homes near the Tennessee River and found corrosion from decades of valley fog, plus that fine yellow-green pollen film that requires more than a basic vacuum pass. This isn’t generic Southern climate; it’s Knoxville-specific, and it changes how we scope and price every job.
Our Main Knoxville Services
Most Knoxville homeowners call us for one of three jobs. Each has its own page with full pricing, process details, and local conditions.
Air Duct Cleaning in Knoxville
We clean the full supply and return network with a Rotobrush rotary brush system that scrubs duct walls while a Nikro negative-air machine pulls dislodged debris out of your home entirely. In Knoxville, we pay special attention to pollen compaction in flexible duct runs and biological buildup in humid basements and crawl spaces common in older neighborhoods. Every job includes before-and-after photos of your own ducts, not stock images. Air Duct Cleaning in Knoxville
Dryer Vent Cleaning in Knoxville
Dryer vent blockages are a genuine fire hazard, and Knoxville’s mature tree canopy means lint traps more debris from open soffit vents and exterior intakes. We run a rotary brush through the full vent line to the exterior cap, measure airflow before and after, and flag any corrugated transition duct that should be replaced with solid metal per code. Dryer Vent Cleaning in Knoxville
Duct Sealing in Knoxville
Knoxville’s older sheet metal and deteriorating flexible ductwork leak conditioned air into attics and crawl spaces year-round. We apply duct sealing mastic and mechanical fasteners at joints, then pressure-test the system to verify results. This is often the most cost-effective upgrade for homes in neighborhoods like Old North Knoxville, where original ductwork is sound in structure but porous at every seam. Duct Sealing in Knoxville

What pushes Knoxville prices toward the higher end: homes with original sheet metal requiring hand-sealing at joints, multiple flexible duct runs with sagging low points, or significant pollen compaction requiring extended brush time. What keeps them lower: straightforward ranch layouts with accessible basements or crawl spaces. Either way, your price is written down before we start, and it does not move at the door.

FAQs About Air Duct Cleaning Company in Knoxville
No permit is required for routine air duct cleaning or dryer vent cleaning in Knoxville. Duct sealing that involves modifying or extending ductwork may need a permit from the city; we handle that determination and any paperwork if it applies to your job. Call (361) 326-5060 and we’ll check your specific scope.
Most Knoxville appointments are available within three to five business days. Peak pollen season in April and May sometimes extends that by a day or two. We don’t quote same-day dispatch because duct cleaning is a scheduled, in-home job that requires proper setup time, not an emergency service.
