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
Most homeowners in Bothell pay between $380 and $620 for a complete residential air duct cleaning, with the job taking four to six hours for a typical single-family home. We dispatch crews from our Seattle office and serve Bothell neighborhoods directly, including Canyon Park, North Creek, and the original downtown core along Bothell-Everett Highway. Call us at (469) 972-3151 for a written estimate before any work begins.
We’ve worked in enough Bothell homes to know the local patterns. The valley-floor humidity here is different from what you’ll find in higher Eastside cities. That moisture gets into duct systems and stays there. Our Air Duct Cleaning team treats the underlying conditions, not just the symptoms.
Why Kestrel Air Duct Cleaning Is Bothell’s Preferred Air Duct Cleaning Company
We’ve built our reputation in Bothell on showing up in the window we promised and putting the price in writing before a single vent is touched. The Kingswell Guarantee, which governs every job we do, was established when the Kingswell family of companies was founded in 2004. That same standard applies to your Bothell home today.
Our technicians are background-checked and uniformed, and they arrive with professional-grade equipment: Rotobrush rotary brush systems for dislodging debris at the duct wall, Nikro negative-pressure units for pulling contaminants out, and Abatement Technologies HEPA filtration to keep loosened particles out of your living space during cleaning. These aren’t box-store shop vacs. They’re purpose-built tools for the work.
Calls are answered by a live person, 24 hours a day. No voicemail queue. No automated system pressing you to “say or press one.” A real conversation, any time you call (469) 972-3151.
Our 365-Day Done Right Promise is documented in writing on every job. If the work falls short within that year, we return and make it right at no charge. That’s not a courtesy we extend when we feel like it. It’s a standing commitment, printed and signed.
Commercial Air Duct Cleaning in Bothell
Commercial Air Duct Cleaning in Bothell addresses the larger-scale systems found in tech-corridor office parks, medical offices along Bothell-Everett Highway, and multi-tenant retail spaces in Canyon Park. These buildings typically use packaged rooftop units with extensive flex duct distribution, and the constant occupancy loads push debris through the system faster than in residential settings. A commercial cleaning in Bothell generally runs $1,200 to $3,800 depending on square footage, system count, and access complexity.
Office and Medical Facility Protocols
We schedule commercial work to minimize disruption to your business operations. Our crews use contained negative-air extraction with HEPA filtration, so loosened particulates don’t migrate into occupied spaces during cleaning. We document the before condition with video inspection and provide the same written price guarantee that our residential customers receive.
Multi-Tenant Coordination
Commercial buildings with multiple HVAC zones require coordinated access across suites or floors. We work with your property manager to sequence the cleaning so no tenant is without climate control for longer than necessary. The Kingswell Way values code governs every visit: say the price, show up in the window we gave, leave the place cleaner, put the guarantee in writing, come back if it fails.
Air Duct Cleaning Services in Bothell
Air Duct Cleaning Services in Bothell cover the full spectrum of residential and light commercial forced-air systems, from 1960s-era sheet-metal duct runs near the original downtown to complex multi-zone flex duct installations in North Creek and Canyon Park subdivisions. A typical residential full-system cleaning in Bothell runs $380 to $620, with supply-only or return-only cleanings starting around $220. Video inspection adds $85 to $150 depending on system complexity.
Residential Full System Cleaning
We clean both supply and return ductwork, including the main trunk lines, branch ducts, and boot connections at each vent. Our Rotobrush system agitates debris from the duct walls while the Nikro negative-air unit maintains constant suction, preventing recontamination of your home during the process. Abatement Technologies HEPA filtration captures particles down to 0.3 microns.
Dryer Vent Cleaning and Shared Stack Systems
Dryer vent cleaning is a separate but related service we offer. In Bothell condos and townhomes, shared dryer vent stacks create a specific hazard: lint accumulates across multiple units, but cleaning often stops at the individual unit connection, leaving combustible material in the shared run. We inspect the full length of shared runs where accessible and document what we find.

Trusted Brands We Service in Bothell
We clean duct systems connected to all major HVAC brands, and we stock filtration and indoor-air-quality products from Honeywell, Aprilaire, and Guardsman for Bothell customers who want to maintain cleaner air between service visits. These aren’t aftermarket substitutes. They’re the manufacturer’s own products, sized and installed for your specific system. If your home in Canyon Park or North Creek has a newer high-efficiency unit with an integrated electronic air cleaner, we can match the replacement media or recommend an upgrade path that fits the duct configuration you already have.
Common Air Duct Cleaning Problems We See in Bothell Homes
- Sagging flex duct with standing condensation. In North Creek and Canyon Park subdivisions built during the 1990s tech-growth wave, vented crawl spaces trap moisture from Bothell’s persistent valley fog. Flex duct sags between supports, creating low points where condensation pools. Mold colonizes these pockets, and homeowners often mistake the resulting symptoms for seasonal allergies.
- Shared dryer vent stacks in condos and townhomes. Multiple units connect to a single vertical run. Individual unit cleaning doesn’t touch the shared section, so lint continues to accumulate. This is a genuine fire hazard that requires access to the full stack, not just the branch connection.
- Second-growth canopy debris at exterior intakes. Bothell’s dense alder and Douglas fir canopy deposits fine organic particulates onto outdoor HVAC intakes year-round. These particulates enter the return system and accelerate buildup compared to homes in more open settings.
- Restricted equipment access in dense apartment complexes. Limited parking forces longer hose runs from the vacuum unit to the building, which can reduce negative pressure at the duct if the technician doesn’t compensate with proper hose diameter and sealing. We’ve developed protocols for these Bothell-specific constraints.
Pricing for Air Duct Cleaning in Bothell, WA
Most Bothell homeowners pay between $380 and $620 for a complete residential air duct cleaning covering supply ducts, return ducts, and the main trunk lines. Supply-only or return-only cleanings typically run $220 to $340. Commercial systems start around $1,200 and scale with square footage and system count. Video inspection, which we recommend for homes with suspected mold or post-renovation debris, adds $85 to $150.
Several factors push costs toward the higher end of these ranges: multi-zone systems with extensive flex duct runs (common in Canyon Park and North Creek), crawl space or attic access that requires additional safety protocols, and homes where the last cleaning was more than ten years ago or never performed. We give you one flat price per system, agreed in writing, before any work starts. No per-vent pricing. No door-step revisions. Call (469) 972-3151 for a free estimate.

FAQs About Air Duct Cleaning in Bothell
Every three to five years for most Bothell homes, though valley-floor properties with vented crawl spaces may need more frequent attention due to accelerated mold cycles. Homes near the Sammamish River or in low-lying North Creek subdivisions should schedule inspection every two to three years. Call (469) 972-3151 and we’ll assess your specific conditions.
Yes, we clean shared dryer vent stacks where building access allows, and we document the full run with video inspection when possible. Individual unit cleaning alone leaves lint in the shared section, which is why we always ask about the building configuration before quoting. For condos near Bothell Landing or in the Canyon Park core, we coordinate with property management for roof or utility room access.
Sagging 1990s-era flex duct in vented crawl spaces with standing condensation at low points. The valley humidity collects where the duct sags between supports, creating persistent mold pockets that recolonize quickly after surface cleaning alone. We address the moisture source alongside the duct cleaning to break the cycle.
Yes, we clean commercial systems in office parks and medical facilities throughout the Canyon Park business district and along Bothell-Everett Highway. Commercial jobs use the same equipment scaled to larger systems, with scheduling designed to minimize tenant disruption.
