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 Bothell
Air duct cleaning in Bothell typically runs $350 – $650 for a full residential system, with most jobs completed in a single visit. Our crews dispatch from the Seattle office and carry Rotobrush rotary systems and Nikro negative-air machines through Bothell neighborhoods daily. We’ve worked the valley long enough to know that a home near the Sammamish River corridor needs a different inspection than a Canyon Park townhome built in 2019. Call (361) 326-5060 for a written estimate before any work starts.
Why Hollis Air Duct Cleaning Is Bothell’s Preferred Air Duct Cleaning Company
We’ve been part of the Garrison Partners family since 2004, and our Air Duct Cleaning team has spent years tracing the specific failure patterns that Bothell’s geography creates. The damp river valley, the 1970s tract-home crawlspaces, the pollen loads from alder and cedar – this isn’t theoretical for us. We’ve pulled crushed galvanized runs from behind finished basement walls in North Creek and found black mold on register boots in homes where the living room looked spotless.
Our technicians are background-checked and uniformed. The price is written down before we touch anything. And every job carries the 365-Day Done Right Promise – if the work fails within a year, we come back and make it right at no charge, including a free second visit. Phones are answered by a live person 24 hours a day, 7 days a week. No voicemail loops. No callback queues.
Air Duct Cleaning Services in Bothell
Air Duct Cleaning Services in Bothell start with understanding what kind of house we’re walking into. 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. A typical residential full-system clean in Bothell runs $350 – $550 for homes under 2,500 square feet, with larger homes or commercial systems ranging $450 – $650.
Residential Duct Cleaning
We clean supply and return ducts, registers, grilles, and the air handler cabinet. In Bothell’s older split-levels, we always camera-inspect the trunk line first – we’ve found too many disconnected runs hidden behind drywall to skip this step.
Commercial Duct Cleaning
Office parks near I-405 and retail spaces along Bothell-Everett Highway need scheduled cleaning that doesn’t disrupt business hours. We price commercial systems by square footage and HVAC zones, with written quotes delivered before scheduling.

HVAC Duct Cleaning in Bothell
HVAC Duct Cleaning in Bothell means more than pushing a brush through visible vents. 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 – so duct cleaning here is less about dust and more about moisture management and allergen removal tied to the valley’s specific microclimate. A typical HVAC duct cleaning in Bothell runs $400 – $600 when it includes camera inspection, source removal with negative-air containment, and sealing of accessible joints with mastic.
Video Inspection and Source Removal
We feed a camera through the trunk line before we clean. This shows us crushed runs, disconnected boots, and mold staining that a surface inspection misses. Then we set up negative-air containment and use rotary brush agitation with HEPA filtration to pull debris out rather than pushing it deeper.
Duct Sealing After Cleaning
Cleaning a leaky system is temporary. We seal accessible joints with duct mastic so the air you’ve paid to heat and cool actually reaches the rooms. In Bothell’s older homes, this step often matters more than the cleaning itself.
Trusted Brands We Service in Bothell
Our equipment roster includes Rotobrush rotary brush systems for mechanical agitation, Nikro negative-air machines for containment during cleaning, and filtration products from Honeywell, Aprilaire, Abatement Technologies, and Guardsman. We don’t show up with hardware-store vacuums and call it professional. For Bothell homeowners, this means the same tools commercial crews use on medical and school systems are what we run through your trunk lines. Parts and filters for these brands are stocked locally, so if your system needs a filtration upgrade after cleaning, we can handle it without a return trip.
Common Air Duct Cleaning Problems We See in Bothell Homes
- Black mold on register boots in river-corridor homes. 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 year-round. The living space looks fine. The boots tell a different story.
- Crushed or disconnected runs behind finished basement walls. Original galvanized trunk lines in 1970s – 80s Bothell tract homes have leaky joints and disconnected runs that a surface clean never touches. Skip the camera inspection and you miss the crushed section behind the drywall entirely.
- Construction dust in newer townhomes. Newer Canyon Park and downtown townhomes with sealed flex duct get skipped as “too new to need it,” but construction dust pulled through the air handler and blower motor during the build stays in the system and keeps cycling through a MERV rating that was never upgraded.
- Recurring mildew after seasonal cleaning. Fall alder, cedar, and grass pollen season drives calls, but cleaning without addressing high winter humidity in the valley-floor crawlspace just resets the clock on mildew growth. The moisture source has to be managed, not just the symptom.

FAQs About Air Duct Cleaning in Bothell
Bothell’s valley-floor crawlspaces under 1970s – 80s split-levels vent poorly in our marine climate, so moisture wicks up into original galvanized trunk lines and register boots – which is why we routinely camera black mold staining on boots in North Creek and Sammamish River corridor homes that show no visible mold anywhere in the living space. The dampness hides below grade where homeowners don’t look. A camera inspection finds it before we clean. Call (361) 326-5060 to schedule.
Most 1980s Bothell tract homes have salvageable galvanized trunk lines with localized problems – crushed runs, disconnected boots, leaky joints – rather than systemic failure. We camera-inspect first. If the trunk is intact, cleaning plus sealing runs $400 – $600 versus $3,000 – $7,000 for full replacement. We only recommend replacement when the trunk line itself is corroded through or structurally compromised. Call (361) 326-5060 and we’ll show you what the camera sees before you decide.
Yes, but for a different reason than older homes. Construction dust from drywall sanding, insulation particulate, and concrete residue gets pulled through the air handler during the build and stays in the system. We’ve cleaned Canyon Park townhomes less than five years old with significant debris loads. The sealed flex duct itself is fine; the air handler and supply boots are where the dust collects. A typical newer-townhome clean runs $350 – $450. Call (361) 326-5060 for an estimate.
Fall, before the heating season starts, and late spring, after the alder and cedar pollen peaks subside. Bothell’s wet, mild marine climate – roughly 37 inches of rain a year, high winter humidity, and a damp river valley floor – keeps duct interiors moist for much of the year, promoting mold and mildew growth and making fall and spring pollen seasons a peak time for duct cleaning calls. We book two to three weeks out during these windows, so planning ahead helps. Call (361) 326-5060 to get on the schedule.
Our standard residential job includes camera inspection of the trunk line, negative-air containment setup, rotary brush agitation of supply and return ducts with HEPA filtration, register and grille cleaning, air handler cabinet cleaning, and sealing of accessible joints with mastic. We run before-and-after photos so you see what came out. The price is written before we start. Everything is covered by the 365-Day Done Right Promise. Call (361) 326-5060 for a free estimate.
