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 Bothell, WA
Air duct cleaning in Bothell typically runs $350 – $650 for a whole-home system, with most jobs completed in a single visit. Bothell’s damp Sammamish River valley climate and aging 1970s – 1990s housing stock mean our crews spend as much time addressing moisture-related mold and mildew as they do ordinary dust buildup. We’re Hollis Air Duct Cleaning, and our Bothell work is dispatched and scheduled through our Seattle office with crews who serve the city locally. Call (361) 326-5060 for a free estimate.
Why Bothell Homes Are Different
Bothell sits in the damp, pollen-heavy Sammamish River valley where Puget Sound’s marine air and decades-old suburban growth combine to make HVAC ductwork a magnet for mold, mildew, and seasonal allergens. Duct cleaning here is less about dust and more about moisture management and allergen removal tied to the valley’s specific microclimate.
Much of Bothell’s housing stock is 1970s – 1990s suburban tract homes and split-levels with original galvanized or flex-duct systems, plus a growing ring of newer townhomes and condo complexes near Canyon Park and downtown. Older ducts in these homes often have leaky joints and decades of debris accumulation, while newer builds may use sealed flex duct that still collects construction dust. The roughly 37 inches of annual rain, high winter humidity, and damp river valley floor keep duct interiors moist year-round, promoting mold growth.
Technicians in Bothell routinely find black mold staining on register boots and flex duct in homes near the Sammamish River and North Creek corridors, because the valley’s persistent dampness and poor crawlspace ventilation push moisture into duct systems continuously. Fall and spring pollen seasons, especially alder, cedar, and grass, drive peak demand.
Our Main Bothell Services
Bothell homeowners call us most often for these three services, each with its own dedicated page and pricing.
Air Duct Cleaning in Bothell
Our Air Duct Cleaning in Bothell service uses Rotobrush rotary brush systems and Nikro negative-air machines to dislodge and extract buildup from supply and return lines. In Bothell, we pay special attention to register boots and trunk lines where valley moisture has promoted mold growth, and we document conditions with before-and-after photos for the homeowner’s records.
Dryer Vent Cleaning in Bothell
Our Dryer Vent Cleaning in Bothell service removes lint accumulation from dryer ducts to restore airflow and reduce fire risk. Bothell’s older split-levels and townhomes often have longer vent runs through crawlspaces or interior walls where lint compacts in humid conditions, requiring thorough rotary brushing rather than simple blowing.
Duct Sealing in Bothell
Our Duct Sealing in Bothell service closes leaks in supply and return plenums using duct sealing mastic and metal-backed tape. In Bothell’s original 1970s – 1990s tract homes, galvanized duct seams have often separated after decades of thermal cycling, and flex-duct connections at boots have loosened, sending conditioned air into crawlspaces and attics.

FAQs About Air Duct Cleaning Company in Bothell
No permit is required for routine duct cleaning or dryer vent cleaning in Bothell.

Call (361) 326-5060 and we’ll walk through your specific setup.
Most Bothell appointments are scheduled within two to five business days, with dispatch from our Seattle office. We do not promise same-day service because duct cleaning is a scheduled job that requires proper equipment loading and time allocation.
