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.
Fast, Reliable Air Duct Cleaning Across Kenmore
Most Kenmore homeowners pay between $380 and $650 for a full residential air duct cleaning, with commercial systems running $850 to $2,400 depending on square footage and access. We’re local to the north Lake Washington area and schedule Kenmore jobs from our Seattle office, so crews are typically on-site within a few days of your call, not weeks out.
We know the territory. From the ranch homes lining Juanita Drive to the split-levels near the Sammamish River slough, Kenmore’s housing stock presents a specific challenge: decades-old ductwork running through vented crawl spaces that sit in one of the wettest microclimates in the metro area. Our Air Duct Cleaning team has cleaned hundreds of these systems. We don’t treat your home like a generic suburban job.

Why Kestrel Air Duct Cleaning Is Kenmore’s Preferred Air Duct Cleaning Company
We’ve built our reputation in Kenmore on showing up in the window we promised and leaving the price where we left it. No doorstep revisions. No “we found something else” add-ons. The Kingswell Way, our technician code, requires a written price before the first vent is touched, a defined arrival window, a clean job site, and a written guarantee on every job. That’s been our standard since 2004.
Our crews know the local pattern. Homes within a half-mile of Lake Washington’s north basin show visible mold on crawl-space flex-duct liners at rates we simply don’t see in drier inland suburbs. We’ve learned to check for it systematically, not discover it accidentally during a sale inspection.
Background-checked, uniformed technicians arrive with Rotobrush rotary systems, Nikro negative-pressure units, and Abatement Technologies HEPA filtration. Real equipment, not shop vacs with extra hoses. And when you call, a live person answers, 24 hours a day. No automated queue.
Every job carries our 365-Day Done Right Promise in writing. If the work falls short within that year, we return and make it right at no charge. No discretion, no argument.
Residential Air Duct Cleaning in Kenmore
Residential Air Duct Cleaning in Kenmore means addressing the specific contamination pattern of post-war ranch and split-level homes built during the 1950s through 1980s suburban expansion. These houses route metal trunk lines or early flex duct through vented crawl spaces that sit directly in the Sammamish River-Lake Washington moisture basin. Original ductwork has often gone thirty to forty years without cleaning, accumulating Pacific Northwest construction dust, pollen from the surrounding greenbelt, and moisture-driven biological growth. A typical full-system residential cleaning in Kenmore runs $380 to $650 for homes up to 3,500 square feet, with larger homes or systems with multiple air handlers starting around $720.
Supply and Return Duct Cleaning
We clean both sides of the system. Supply ducts push conditioned air into your rooms; return ducts pull air back to the handler. In Kenmore’s older homes, return trunks often run through the crawl space and collect the most moisture damage. We separate the two systems during cleaning so debris from the dirtier return side doesn’t cross-contaminate your supply lines.
Video Inspection Before and After
Our camera goes in first. For Kenmore homes near the shoreline, we’re specifically looking for mold colonization inside flex-duct liners, where it hides from surface view. After cleaning, we run the camera again so you see the difference in your own ducts, not ours.
Commercial Air Duct Cleaning in Kenmore
Commercial Air Duct Cleaning in Kenmore covers the retail spaces along Bothell Way, medical offices near Kenmore Town Center, and the warehouse and light-industrial buildings that serve the city’s working waterfront and service corridors. These systems typically use larger gauge metal duct with rooftop handlers and require negative-air extraction, meaning we seal the system and pull contaminants out under controlled vacuum pressure rather than blowing them into occupied space. Commercial pricing in Kenmore starts at $850 for small retail systems and ranges to $2,400 for larger buildings with multiple zones or hard-access rooftop equipment.
System Access and Containment
Commercial buildings in Kenmore often operate during business hours, so we coordinate after-hours or weekend work to avoid disrupting your operation. Our Nikro negative-pressure units create contained work zones so loosened debris doesn’t enter your retail floor or patient waiting area.
Maintenance Interval Planning
We document system condition and recommend realistic cleaning cycles based on your building’s use, occupancy load, and whether you’re pulling return air from spaces with higher particulate generation. For Kenmore commercial clients, we put the next recommended service date in writing before we leave.
Trusted Brands We Service in Kenmore
We clean ductwork connected to every major HVAC brand, and we stock Aprilaire media filters and Guardsman vent covers for common Kenmore installations. For homeowners who want to maintain cleaner air between service visits, we also carry Abatement Technologies portable HEPA air scrubbers and can recommend Aprilaire whole-home filtration upgrades sized to your existing handler. Our technicians travel with the fittings and adapters that fit the Trane, Carrier, Lennox, and Rheem systems we see most often in north Lake Washington homes, so most filter or vent replacements happen same-visit without a parts run to Lynnwood or Bothell.
Common Air Duct Cleaning Problems We See in Kenmore Homes
- Crawl-space mold in flex-duct liners. The persistent humidity from the Sammamish River and Lake Washington convergence causes condensation inside vented crawl spaces from October through April. We regularly find black mold growing on the interior surface of flex-duct sections, especially in homes south of 68th Avenue NE near the shoreline.
- Compounded construction dust in original metal trunk lines. Kenmore’s 1950s-1970s ranchers often still have their original galvanized steel trunks. Decades of Pacific Northwest remodeling, drywall work, and older fiberglass insulation breakdown have left layered sediment that standard vacuuming won’t dislodge.
- Moisture-damaged flex-duct with collapsed sections. The same crawl-space humidity that grows mold also saturates the fiberglass liner and causes flex duct to sag, separate at joints, or collapse entirely. We flag these failures during camera inspection so you can address them before they restrict airflow or pull unconditioned crawl-space air into your living space.
- Outbuilding and shop system overload. Rural properties on the fringes of Kenmore, particularly those with unpaved driveways and wood heat in shops or detached garages, see dramatically higher dust and ash loading. These particles migrate into the main house duct system or overwhelm separate outbuilding air handlers.

FAQs About Air Duct Cleaning in Kenmore
Kenmore homes need cleaning every 3 to 4 years, while drier inland suburbs like Bothell or Woodinville can often stretch to 5 years. The Sammamish River-Lake Washington moisture basin creates higher year-round humidity and crawl-space condensation that accelerates mold spore accumulation and flex-duct deterioration. Rural properties with unpaved roads, wood heat, or outbuilding systems should plan on the shorter end of that interval. Call (469) 972-3151 and we’ll assess your specific conditions.
Kenmore’s lake-basin geography traps ambient moisture; the convergence of Lake Washington’s north end and the Sammamish River creates a persistent humidity layer that hillside suburbs like Woodinville simply don’t experience. From October through April, this dampness condenses on the interior of flex-duct liners in vented crawl spaces, creating the sustained wet surface mold needs to colonize. We see this pattern routinely in Kenmore homes within a half-mile of the shoreline. Woodinville’s higher elevation and better drainage keep crawl-space humidity below that threshold.
Yes. Wood heat produces fine ash particulate that overwhelms standard filtration and loads duct systems far faster than gas or electric heat. If your shop or outbuilding shares air handling with your main house, or if the outbuilding has its own system, plan on cleaning every 2 to 3 years. The ash is abrasive to blower motors and migrates into living spaces through poorly sealed returns. We clean outbuilding systems with the same Rotobrush and negative-air equipment we use in main residences.
We start with a video inspection of the crawl-space flex runs, specifically looking for mold on the liner interior and collapsed sections from moisture damage. Then we seal the system and use Rotobrush rotary agitation to dislodge debris from duct walls, paired with Nikro negative-air extraction under HEPA filtration from Abatement Technologies so loosened particles don’t enter your living space. We clean supply and return lines separately, sanitize the trunk, and run a final camera pass so you see the result. The whole process takes 3 to 5 hours for a typical 1,800-square-foot rancher.
Longer drives to rural properties on the edges of Kenmore don’t change your price or our equipment loadout, but they can affect scheduling windows. We batch outlying jobs to minimize transit time between appointments, so you may get a morning or afternoon slot rather than an exact hour. We bring the same Rotobrush, Nikro, and Abatement Technologies setup to every job, regardless of driveway length. Call (469) 972-3151 and we’ll find a window that works.
