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.

Why Hollis Air Duct Cleaning Is Bothell East’s Preferred Air Duct Cleaning Company
We’ve been in business since 2004 as part of the Garrison Partners family, and our reputation in Bothell East is built on showing up inside the window, pricing in writing, and leaving the site clean. Bothell East homeowners aren’t looking for the lowest teaser quote; they’re looking for a crew that won’t renegotiate at the door or disappear when something fails. Our 365-Day Done Right Promise covers every job in writing: if the work fails within a year, we return and make it right at no charge, including a free second visit. Technicians are background-checked and uniformed; phones are answered by a live person 24 hours a day, 7 days a week. We know Bothell East’s housing stock, the 1990s – 2000s subdivisions with flex duct in damp attics, and the newer tight-envelope townhomes where performance matters more than debris removal. That local knowledge means we don’t waste time guessing what your system needs.
Air Duct Inspection in Bothell East
Air Duct Inspection in Bothell East starts with a camera run through your supply and return ducts to see what’s actually inside, not what we assume from the register covers. In this market, we find two distinct problems: construction debris in newer homes and biological growth in the damp flex duct of 1990s – 2000s builds around North Creek and Canyon Park. A typical inspection in Bothell East runs $150 – $250 and includes a written report with photo documentation. We recommend an inspection before any cleaning work so you know whether you’re dealing with drywall dust, moldy debris, or both.
Video Inspection for Hidden Growth
Our camera systems show the interior condition of flex duct runs in attics and crawlspaces that no homeowner can see without tearing into walls. In Bothell East’s humid microclimate, we regularly find greyish-black biological growth coating the inside of return ducts in homes less than 20 years old. The video becomes part of your record and helps us quote accurately.
Post-Construction Debris Assessment
New Bothell East townhomes and subdivisions often have drywall dust, sawdust, and insulation scraps left in the ducts at handover. An inspection documents this before your first heating season pushes it through the blower motor and into your living space. We see this in Canyon Park builds regularly.
Residential Air Duct Cleaning in Bothell East
Residential Air Duct Cleaning in Bothell East means source removal from the entire duct system, not just wiping the registers. We use negative-air machines from Nikro with HEPA filtration at the air handler, plus rotary brush agitation through supply and return runs. In Bothell East’s damp climate, mechanical cleaning alone often isn’t enough; we apply antimicrobial treatment where inspection shows biological growth. A typical residential job in Bothell East runs $350 – $650 depending on system size, accessibility, and whether the home needs antimicrobial treatment in addition to mechanical cleaning. Our Air Duct Cleaning team follows The Garrison Code on every job: arrive inside the window, price in writing, complete the work by the book, leave the site clean.
Full System Source Removal
We clean every component the air touches: supply ducts, return ducts, trunk lines, and the air handler cabinet. In Bothell East’s 1990s – 2000s subdivisions, this matters because builder-grade flex duct has more surface area for debris and microbial growth than rigid metal ductwork. We seal the system under negative pressure so nothing escapes into your home during cleaning, and we offer Duct Sealing in Bothell East to stop leaks at the source.
Antimicrobial Treatment for Damp-Climate Growth
Bothell East’s 150+ rain days annually create conditions where mold and mildew persist inside duct insulation. Where inspection shows biological growth, we apply treatment after mechanical agitation and before re-sealing connections. This step prevents regrowth in the damp microclimate that standard cleaning can’t address long-term.
Trusted Brands We Service in Bothell East
Our equipment roster includes Nikro negative-air machines, Honeywell filtration components, and Aprilaire media filters, the same tools commercial crews use, maintained to manufacturer spec and explained in plain terms on every job. We stock common replacement parts for Bothell East customers so turnaround stays short when a filter housing, damper, or flex connection needs attention during cleaning. The rotary brush systems we run through your ducts are professional-grade, not hardware-store rentals, and our HEPA filtration captures particles down to 0.3 microns. If your system uses Abatement Technologies components or Guardsman filtration products, we service those too.
Common Air Duct Cleaning Problems We See in Bothell East Homes
- Construction debris in new homes. Builders hand over Bothell East townhomes with drywall dust and sawdust still sitting in the supply and return ducts. The first season of heating or AC pushes that debris through the blower motor and into living spaces, and owners assume a new house means clean ducts.
- Greyish-black mold in return flex duct. Bothell East’s damp microclimate turns unsealed builder-grade flex duct into a condensation surface. We regularly pull wads of moldy debris from return ducts in Canyon Park and North Creek homes less than 20 years old.
- Superficial cleaning that misses the source. Some crews wipe visible registers and call it done, leaving moldy debris in the return runs and air handler that Bothell East’s humidity produces. No negative pressure, no source removal, no antimicrobial treatment.
- Damaged flex duct from aggressive cleaning. Flex duct in Bothell East attics and crawlspaces gets cleaned too aggressively with the wrong tools, tearing the inner liner and creating new lint pathways and condensation surfaces. We match agitation method to duct type.

FAQs About Air Duct Cleaning in Bothell East
Yes, and more often than owners expect. Builders in Bothell East frequently leave drywall dust, sawdust, and construction debris in the ducts at handover, and the first two years of HVAC cycling push that material through your blower motor and into your living space. Call (361) 326-5060 for a video inspection to see what’s actually in there.
That smell usually means biological growth inside your return duct runs, common in Bothell East’s damp microclimate where unsealed flex duct in cool crawlspaces becomes a condensation surface. We were called to a 2000s-built home near Canyon Park where the homeowner’s complaint was exactly this, and our camera inspection showed heavy greyish-black biological growth coating the inside of the return flex run. We set up negative pressure with HEPA filtration at the air handler, ran agitation tools through the supply and return ducts, and pulled wads of moldy debris out of the returns before applying antimicrobial treatment and re-sealing the flex connections that had been leaking damp crawlspace air into the system. Call (361) 326-5060 if you’re smelling this in your Bothell East home.
Builders should have sealed ducts during construction to keep out drywall dust and debris, then performed a post-construction cleaning before handover. In Bothell East, they should also have sealed flex duct connections against the damp crawlspace air that promotes microbial growth. Most didn’t. Call (361) 326-5060 and we’ll show you what you’re working with.
In Bothell East’s damp climate with 150+ rain days annually, we recommend inspection every 3 – 5 years and cleaning when video shows debris or biological growth. A drier city might stretch to 5 – 7 years because moisture-driven microbial growth isn’t the same factor. The flex duct in North Creek and Canyon Park subdivisions makes Bothell East homes more susceptible to condensation-related problems than homes with rigid metal ductwork in arid climates. Call (361) 326-5060 to set your schedule.
We clean the whole system: supply ducts, return ducts, trunk lines, and the air handler cabinet. Cleaning only the registers is the exact shortcut that leaves Bothell East homeowners with persistent musty smells and circulating debris. Our negative-air method with HEPA filtration captures what we agitate loose, and we document the before condition with video. Call (361) 326-5060 for a full-system quote.
