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 Duvall, WA
Air duct cleaning in Duvall means dealing with a specific set of conditions most Eastside homes never face: valley fog, agricultural dust, and 20-to-30-year-old flex ductwork running through vented crawl spaces. Most Duvall homes fall between $450 and $900 for a full-system cleaning, depending on size, contamination level, and whether the crawl-space runs show the moisture staining we check for on every quote. We’re Kestrel Air Duct Cleaning, and we approach every Duvall job with these local realities in mind. Call (469) 972-3151 for a written, no-surprises price before any work begins.
Why Duvall Homes Are Different
Duvall sits in the Snoqualmie River valley, where fog settles in for long stretches and relative humidity stays higher than it does ten or fifteen miles west. That damp air finds its way into unconditioned crawl spaces, where HVAC flex duct runs pick up moisture and hold it. When you combine that with the hay dust, animal dander, and mold spores drifting off the surrounding horse farms and hay fields, the inside of a Duvall duct system often looks nothing like what you’d find in a Sammamish or Redmond home of the same age.
Most Duvall housing stock dates from the 1990s and early 2000s, when the city grew quickly. Those homes now have original flex ductwork that has never been professionally cleaned. The older farmhouses on larger parcels are different again: many have retrofit duct systems that were adapted rather than designed, with joins and seams that collect debris in ways a factory-built layout does not.
One thing we’ve learned to check on Duvall jobs is the condition of flex duct insulation in lower crawl-space runs. Homes that took on water during past Snoqualmie River flood events sometimes carry silt staining on the underside of duct insulation – a sign that standard cleaning won’t address the full scope. We look for that tide-line marking before we quote.
Our Main Duvall Services
Duvall homeowners call us most often about two jobs: full-system air duct cleaning and dryer vent cleaning. Each has its own dedicated page with the full details.
Air Duct Cleaning in Duvall
Full-system air duct cleaning in Duvall means pulling the accumulated hay dust, dander, construction debris, and mold spores out of your supply and return runs. We use Rotobrush rotary brush agitation to dislodge debris at the duct wall and Nikro negative-pressure extraction to pull contaminants out of the home. In Duvall specifically, we pay close attention to supply-boot seams and crawl-space plenums, where valley moisture accelerates biofilm growth more than it does on higher ground.

Dryer Vent Cleaning in Duvall
Dryer vent cleaning is the job homeowners delay most often, and in Duvall the risk profile is real. Clogged dryer vents are a fire hazard, and valley homes with long vent runs through crawl spaces or out through roofs accumulate lint faster than shorter, straight-shot runs. We clean the full vent path from the dryer to the exterior termination point and check the lint trap bypass for blockage. Dryer Vent Cleaning in Duvall

What Duvall Customers Say
"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."
- Terrence Boyd"My wife's allergies were awful every morning. Had the ducts done and it's made a real difference. Tech was on time and wore booties in the house without me asking."
- Rob Pendergast"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."
