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 HVAC Cleaning Across Maryville
HVAC cleaning in Maryville, TN typically costs $425-$690 for a full system cleaning on a standard single-family home, and most jobs are completed in 3-5 hours. The work involves cleaning the evaporator coil, blower assembly, air handler, and all supply and return duct runs, then documenting every step with before-and-after photos. If your system hasn’t been opened up in years, or if you’ve noticed musty air coming through the vents in a crawl-space home, call us at (806) 606-6902 for a written quote before anything gets touched.
CleanRun Air Duct Cleaning serves homeowners throughout Maryville, from the older ranch subdivisions near Montvale Road to the newer builds off Morganton Road and beyond. The valley geography here creates a specific set of problems for HVAC systems, and we’ve learned exactly what to look for after years of camera inspections in Blount County homes. You’ll know the price before work starts. You’ll see the inside of your ducts before and after. No shop-vac noise and no mystery invoice at the end.
Why CleanRun Air Duct Cleaning Is Maryville’s Preferred HVAC Cleaning Company
We built our reputation in Maryville by doing the thing most companies won’t: showing you the evidence. Every job includes a Documented Photo Record of every duct run, shot before and after, so you can see the difference between real source removal and a vacuum waved at a register. Tomas Reyes started CleanRun in 2013, and the standard hasn’t drifted since: written price first, photos after, and a 365-Day Done Right Promise in writing on every job.
Homeowners in Maryville call us because the biology here is specific. The pollen load from the surrounding hardwood forests settles into duct interiors fast, and crawl-space moisture pushes mold spores into return-air boots in a way flatland homes never deal with. Our technicians are background-checked, uniformed, and arrive with equipment from Rotobrush and Abatement Technologies that’s built for negative-pressure extraction, not surface agitation. We don’t ask you to trust us. We hand you the photos.
We coordinate scheduling from our Memphis office, but the crews that arrive at your Maryville home are local to the area and know the housing stock: ranch and split-level homes on crawl foundations, flex duct in unconditioned spaces, and the moisture problems that come with Blount County’s hilly terrain. That local knowledge changes what gets quoted and what gets cleaned.
Our HVAC Cleaning Services in Maryville
Evaporator Coil Cleaning
Your evaporator coil sits inside the air handler and gets coated with everything the system pulls in. In Maryville, that means tree pollen, mold spores, and fine organic debris from the valley’s dense hardwood canopy. A dirty coil reduces airflow, forces the blower to work harder, and re-contaminates ductwork within weeks of a cleaning. We clean the coil with professional-grade solutions and document the before and after with photos so you can see the difference.
Blower Cleaning
The blower wheel pushes conditioned air through your entire duct system. When it’s caked with dust and biological growth, the air crossing it picks up that contamination on every cycle. In Maryville homes where humidity stays elevated for long stretches, blower cleaning is often the difference between clean ducts and musty air that returns in a month. We pull the blower, clean the wheel and housing, and show you what came off it.
Condenser Cleaning
The outdoor condenser unit gets hit with Maryville’s full pollen season, cottonwood, and leaf debris from surrounding trees. A clogged condenser coil drives up energy use and shortens compressor life. We clean the coil, check refrigerant pressures, and clear the surrounding area of obstructions so the unit can reject heat properly. This is standard on our full-system cleaning, not an upgrade.
Air Handler Cleaning
The air handler is the box that houses the coil and blower. In crawl-space homes in Maryville, the air handler often sits in a damp, unconditioned space, and the interior becomes a mold incubation chamber. We clean the entire handler cabinet, the drain pan, and the coil, then apply an antimicrobial treatment to the interior surfaces. For homes with persistent musty odor, this is usually where the problem lives.

BeforeAfterTrusted Brands We Service in Maryville
We work on all major HVAC brands: Trane, Carrier, Lennox, Goodman, Rheem, York, and Daikin, plus older systems still running in 1960s and 1970s ranch homes across the city. Our trucks carry common replacement parts and coil treatment products from Guardsman, so we don’t have to schedule a second visit for basic hardware. If your system is older and the coil is degrading, we’ll tell you straight and put the condition in writing, with photos, before recommending any repair path.
Common HVAC Cleaning Problems We See in Maryville Homes
- Mold in return-air boots and flex duct in crawl-space homes. The older ranch and split-level homes south of downtown Maryville, particularly off Montvale Road and along the foothill subdivisions, sit on crawl spaces that pass ground vapor into unconditioned duct runs. We find black mold colonization in the first few feet of flex duct as a rule, not an exception.
- Heavy pollen loading in supply ducts during spring bloom. A single spring storm off the Smokies can coat outdoor surfaces in yellow film, and air handlers cycling constantly during those weeks pull that organic load directly into the duct interiors. Homes near the greenway corridors and tree-dense lots see heavier accumulation.
- Clogged evaporator coils on systems that run heavy during allergy season. When the coil is already caked with pollen and dust, airflow drops and the system can’t condition the house properly. Cleaning the ducts without cleaning the coil leaves the system re-contaminating itself within weeks.
- Rodent intrusion in return ducts under older homes. The hilly terrain around Maryville puts many crawl spaces at grade level, and unsealed return boots are an open invitation. We’ve pulled nests, droppings, and chewed flex duct out of return lines on multiple Meadowbrook and College Hill area homes.
Pricing for HVAC Cleaning in Maryville, TN
A full HVAC cleaning for a typical single-family Maryville home runs $425-$690, depending on square footage, number of returns, and whether the coil and blower require deep cleaning. Crawl-space homes with biological contamination in return boots and flex duct typically land at the upper end due to the sealing and sanitizing work required. Condo and townhome systems with shared building constraints fall in the $350-$525 range. Every quote is written before work begins, per Haven Standard Clause 1, and it’s the number you pay. No per-vent pricing, no bait-and-switch, no “well, while we’re here…” invoice creep. Call (806) 606-6902 and we’ll put a line-item number on your specific home.

FAQs - HVAC Cleaning in Maryville
Because the cleaning never addressed the source. In Maryville’s crawl-space ranch and split-level homes, ground vapor pushes moisture into return-air boots and the first few feet of flex duct through unsealed foundations. If the boots aren’t sealed and sanitized as part of the cleaning, mold re-colonizes within weeks. At CleanRun, boot sealing and interior sanitizing are standard on any crawl-space home, not an add-on. That’s the difference between a cleaning that lasts and one that doesn’t. Call (806) 606-6902 and we’ll put it in writing.
Most Maryville homes with surrounding hardwood canopy should have a full HVAC cleaning every 3-5 years, and more frequently if you have visible pollen accumulation, musty odors, or a crawl-space system with moisture exposure. The valley geography concentrates pollen and organic debris, so the answer here skews shorter than in flatter, less forested parts of Tennessee. If you haven’t had it done in five years or more, you’re overdue. Call for a written quote at (806) 606-6902.
Yes. The air handler houses the evaporator coil and blower wheel, and in Maryville homes with elevated humidity, those surfaces become the primary reservoir for mold and biological growth. Cleaning ducts without cleaning the air handler is like vacuuming a room while leaving garbage sitting in the corner. We pull the blower, clean the wheel and housing, scrub the coil, and treat the drain pan as part of every full-system cleaning.
Yes, and this is one of the most common findings in Maryville homes. The coil sits in a dark, damp environment inside the air handler, and biological growth on the coil surfaces gets picked up by the air stream and pushed through the registers. If ducts are cleaned but the coil is left untouched, the musty smell usually returns within days or weeks. Coil cleaning with antimicrobial treatment is standard on our full HVAC cleaning, not an upsell.
Expect 3-5 hours, depending on system size and access. We’ll need to reach the air handler, the return registers, and any crawl-space duct runs. Our equipment runs on a truck-mounted negative-pressure unit with HEPA filtration, which generates moderate noise outside the home but keeps dust contained inside. Inside, you’ll hear airflow and agitation tools running through the ducts, but no shop-vac rumble. We photograph every duct run before and after, and you get the photo record when we finish. Call (806) 606-6902 for a written quote specific to your home.
