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 Seattle, WA
Most Seattle homes need air duct cleaning for one specific reason: moisture. The city sits above 70% relative humidity for much of the year, and homes built before forced air was standard often have retrofitted ductwork running through damp, vented crawl spaces. That combination breeds mold and biofilm inside ducts far more often than dust buildup does. Kestrel Air Duct Cleaning handles those moisture-driven jobs with professional-grade equipment and a written price before any work begins. Call (469) 972-3151 for a free estimate.
Why Seattle Homes Are Different
Seattle’s residential core is dominated by pre-1940 Craftsman bungalows and early frame homes. Neighborhoods like Ballard, Queen Anne, Fremont, and Capitol Hill were largely built without forced-air systems. When ductwork was added later, it was often routed through unconditioned crawl spaces with poor sealing. That means flex ducts and metal runs sit in persistently damp air, pulling in condensation and whatever is growing in the crawl space.
Postwar housing in South Seattle and Rainier Valley is not exempt. Pier-and-beam construction with vented crawl spaces is common there too, and below-floor duct runs face the same moisture infiltration. Seattle’s marine climate delivers near-constant overcast and elevated humidity rather than dramatic rainfall, so crawl spaces and wall cavities stay damp year-round. Mild winters add another wrinkle: forced-air systems run short, low-intensity cycles, so ducts never fully dry out between uses the way they might in a colder inland climate.
Our Main Seattle Services
Seattle homeowners call us most often about two jobs. Each has its own Seattle page where you’ll find full pricing and details.
Air Duct Cleaning in Seattle
In Seattle, air duct cleaning usually means addressing biological growth as much as dust and debris. Technicians working in retrofitted Craftsman homes in Ballard or Fremont often find flex duct coated with a mix of Douglas fir pollen, mold spores, and condensation residue. That requires antimicrobial treatment after mechanical cleaning, not just a brush pass. We use Rotobrush rotary brush systems to dislodge debris at the duct wall and Nikro negative-pressure units to pull contaminants out, with Abatement Technologies HEPA filtration keeping loosened particles from re-entering your living space. See full details on our Air Duct Cleaning in Seattle page.
Dryer Vent Cleaning in Seattle
Seattle’s damp air makes lint cling inside dryer vents, and the longer the vent run, the worse the buildup. Pier-and-beam homes in South Seattle often have long vent runs through crawl spaces, where moisture and lint combine into a dense mat that restricts airflow. We clean the full run from dryer to exterior termination point and verify airflow afterward. If you’re not sure whether your vent needs attention, our Dryer Vent Cleaning in Seattle page explains the signs and gives exact pricing.

FAQs About Air Duct Cleaning Company in Seattle
We schedule most Seattle appointments within a few business days. Our office coordinates dispatch from Seattle, and we give you a defined arrival window when you book. We arrive inside that window or you hear from us first. Call (469) 972-3151 and a live person will confirm the next available slot.
Air duct and dryer vent cleaning do not require city permits in Seattle. If you live in a condo or a neighborhood with an HOA, check your governing documents; some buildings require advance notice for any contractor access to mechanical rooms or rooftops. We’re happy to provide whatever documentation your HOA requests before we arrive.
Seattle’s humidity means many jobs include antimicrobial treatment for mold and biofilm, which adds labor and material cost. Retrofitted ductwork in older homes also tends to be harder to access than new-construction runs. The written quote you get before work starts accounts for all of that, so the price doesn’t change when we arrive. Call (469) 972-3151 for a free estimate.

What Seattle Customers Say
"Bought an older home and the previous owners had pets everywhere. After Kestrel did the ducts the stale smell was just gone. On time, quick, and they showed me the filter they pulled."
- Preston Ngata"Our dryer was taking two cycles to dry a load. They cleaned the vent and pulled out a frightening amount of lint. Dries in one cycle now and honestly I feel better about the fire risk."
- Marcus Lee"Set up an appointment for the whole house plus the dryer line. They called the morning of to confirm, showed up in the window, and showed me pictures of the gunk they pulled out. Worth it."
