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 comes with a set of conditions you won’t find fifteen minutes west on the plateau. Homes here sit in the Snoqualmie Valley, where persistent fog and a high water table push moisture into crawl spaces and duct runs that were installed decades ago. That means the work we do in Duvall is less about a quick surface vacuum and more about finding the damp, organic buildup that valley air leaves behind. We’re Morton’s Air Duct Cleaning, and our crews work throughout Duvall with written pricing before any work starts. Call (323) 918-4345 and a real person will answer.
Why Duvall Homes Are Different
Duvall sits on the floor of the Snoqualmie Valley, a topographic bowl that traps marine moisture far more persistently than the plateau cities to the west. The result is chronically damp indoor air, and that changes what happens inside ductwork. Valley fog and high relative humidity load the air with organic particulates from the surrounding second-growth red alder and Douglas fir forest. Those spores and pollen grains don’t just arrive in spring; they accumulate in duct interiors year-round, and in Duvall they find the moisture they need to hold on and grow.
The housing stock compounds the problem. Most of Duvall’s residential neighborhoods were built during the 1990s and 2000s expansion that turned the town from farmland into a King County bedroom community. That means a large share of homes have original flex-duct and sheet-metal systems now 20 to 30 years old, and many have never been professionally cleaned. Crawl-space duct runs are common in these single-story and split-level builds, which leaves ductwork vulnerable to ground moisture intrusion from the valley’s high water table. In the lower-lying subdivisions near the Snoqualmie River corridor, we regularly find flex ducts with exterior condensation damage and interior mold streaking that homeowners never knew about until a camera inspection. It’s a failure mode far more common here than in the hilltop neighborhoods above town.
Our Main Duvall Services
Duvall homeowners call us most often for two things: cleaning the air ducts that carry heated and cooled air through the house, and clearing the dryer vent that carries lint and moisture out. Each service has its own page with pricing and details, linked below.
Air Duct Cleaning in Duvall
Air duct cleaning here means dealing with what the Snoqualmie Valley puts into a home’s air. We connect professional-grade negative-air equipment from Rotobrush and Nikro to your system and remove the accumulated dust, pollen, and mold spores that valley fog and seasonal flooding push into HVAC intakes. Every visit includes shoe covers and drop cloths before any equipment comes inside, and we work quietly enough that a napping toddler won’t wake up. Full details and Duvall pricing are on the Air Duct Cleaning in Duvall page.
Dryer Vent Cleaning in Duvall
Dryer vents in Duvall work against the same damp air as everything else. Lint that would stay dry and loose in a plateau home can turn into a compacted, damp mat inside a valley vent run, especially in older homes where the vent exits through a crawl space. That slows drying times and becomes a fire hazard. We clean the full vent run with professional equipment and check for the moisture damage that Duvall’s conditions make more likely. Details and pricing are on the Dryer Vent Cleaning in Duvall page.
Every Morton’s job in Duvall includes the 365-Day Done Right Promise. If the work isn’t right, we make it right. That’s stamped on every job we do, not offered as an afterthought.

Pricing for Air Duct Cleaning Company in Duvall, WA
| Service | Typical range in Duvall |
|---|---|
| Single HVAC system, up to 10 vents | $350 - $475 |
| Single HVAC system, 10-15 vents | $425 - $575 |

Two things push Duvall prices toward the upper end of those ranges. The first is aged flex duct in crawl spaces that needs careful handling or repair before cleaning can start. The second is moisture: when a camera inspection shows mold streaking inside a duct run, the job takes longer because we clean to remove it properly, not just brush past it. Whatever the number, you get it in writing before we start. No per-vent pricing. No surprises on the invoice.
