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.
Air Duct Cleaning Company in Maryville, TN
Hollis Air Duct Cleaning handles the full range of residential ductwork jobs in Maryville, from whole-system cleaning and dryer vent runs to sealing leaky supply lines in crawl spaces. Most calls here involve 1970s – 1990s ranch and split-level homes with original galvanized or early flex duct that’s never been cleaned, loaded with decades of pollen, mold spores, and red clay dust from the Great Smoky Mountains foothills. Our crews dispatch from the Memphis office and work Maryville homes with the same equipment we use on commercial jobs: Rotobrush rotary systems, Nikro negative-air machines, and filtration hardware from Honeywell and Aprilaire. Call (361) 326-5060 for a free estimate.
Why Maryville Homes Are Different
Maryville sits in a humid subtropical valley where the HVAC runs hard year-round: cooling against muggy East Tennessee summers, then heating through damp, chilly winters. Spring brings some of the highest pollen counts in the Southeast, and fall leaf decay near the Smokies drives more particulate into return ducts than you’ll see in drier climates.
The housing stock tells the rest of the story. Blount County grew fast as a Knoxville bedroom community from the 1970s through the 1990s, and much of Maryville was built in that window. Ranch and split-level homes on crawl spaces and slabs dominate. The original flex duct from that era is brittle, often sagging, and prone to rodent nesting once temperatures drop. Crawl-space runs collect standing water after spring thunderstorms, especially where drainage was never properly graded. That’s where mold colonies start, and it’s almost always the source when a homeowner calls us about a musty smell hitting the vents in April.
We check return-air plenums first on older Maryville homes. The fix isn’t always cleaning, sometimes it’s sealing or rerouting, but you can’t know until you’re in the crawl space looking at water stains on the duct jacket.
Our Main Maryville Services
Maryville homeowners call us most often for these three jobs. Each has its own page with full details, pricing, and what to expect on the day.
Air Duct Cleaning in Maryville
We clean the full supply and return system with a Rotobrush rotary brush and high-suction Nikro negative-air machine, pulling loosened debris out of the home rather than pushing it into rooms. In Maryville, this matters more than in drier markets: the biological load here is heavy, and homeowners often smell the difference within hours of the first cycle after cleaning. We photograph the duct interior before and after, and the price is written down before we start. Air Duct Cleaning in Maryville has the full breakdown.

Dryer Vent Cleaning in Maryville
Lint buildup in dryer vents is a fire hazard and a efficiency killer, and Maryville’s older homes often have long, convoluted vent runs through crawl spaces or interior walls that were never designed for modern dryer loads. We run a rotary brush through the full line to the exterior termination, check airflow with a meter, and flag any sagging flex sections that trap moisture. Dryer Vent Cleaning in Maryville covers pricing and what’s included.

Duct Sealing in Maryville
Leaky ducts in Maryville crawl spaces waste conditioned air and pull in mold spores, radon, and crawl-space humidity. We seal accessible joints and seams with mastic and mesh, then pressure-test the system to verify the seal holds. This is often the right move when cleaning alone won’t solve a musty smell or uneven room temperatures. Duct Sealing in Maryville explains when sealing makes sense versus replacement.

FAQs About Air Duct Cleaning Company in Maryville
No permit is required for standard residential duct cleaning or dryer vent cleaning in Maryville. Duct sealing that involves modifying or extending ductwork may need a Blount County permit if it changes the system’s capacity or routing; we handle that determination and any paperwork if it applies. Call (361) 326-5060 and we’ll check your specific job.
Most Maryville appointments are available within three to five business days, sometimes sooner depending on route density. We do not book same-day or emergency dispatch for duct cleaning, it’s scheduled work that takes two to four hours on site, and we prefer to price it properly rather than rush. Call (361) 326-5060 to check current openings.
Most Maryville HOAs do not regulate interior ductwork maintenance, though a few newer subdivisions require notice for any service vehicle parked in the driveway during certain hours. We carry proof of insurance and background-check documentation for any HOA that asks. If you’re unsure, call (361) 326-5060 and we’ll confirm what’s needed before we arrive.
