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 Summit, WA
Homeowners in Summit, WA typically pay $380 – $620 for whole-house air duct cleaning, with most jobs scheduled within a week and completed in a single visit. What makes Summit different from other Puget Sound markets is its concentration of 1990s-and-newer homes with flexible ductwork, combined with diesel particulate exposure from nearby I-5 that shows up as black staining on supply registers. We’re Hollis Air Duct Cleaning, part of the Garrison Partners family, and we dispatch crews to Summit from our Seattle office with Rotobrush rotary systems and Nikro negative-air machines. Call (361) 326-5060 for a written estimate before any work starts.
Why Summit Homes Are Different
Summit’s housing boom produced thousands of homes with flexible ductwork that behaves differently than the rigid metal ducts in older Tacoma or Seattle neighborhoods. These flex runs sag between joists, collect dust at low points, and can kink when crews move through attics, so our technicians map the system before agitation begins. Homes near the Summit Library built in the 1960s and 70s have the opposite problem: galvanized steel ducts that shed rust flakes and require gentler rotary brush settings.
The wet, mild climate here keeps humidity high through winter, especially when heat pumps cycle less during shoulder seasons. That moisture, combined with organic dust load, produces mildew odors that homeowners notice first at return grilles. We see this pattern regularly in Summit’s I-5 corridor neighborhoods, where diesel soot adds a visible black layer to the problem. The Garrison Standard requires us to photo-document this before we start and show the homeowner the difference after.
Our Main Summit Services
Most Summit homeowners call us for one of three jobs. Each has its own page with full pricing, equipment details, and what to expect on the day.
Air Duct Cleaning in Summit
We clean the full supply and return system with a Rotobrush rotary brush and HEPA vacuum, plus register covers and the plenum. In Summit, we pay special attention to flex duct sag points and the black diesel staining common near I-5. Every job gets a written price upfront and before-and-after photos of your own ducts, not stock images. Air Duct Cleaning in Summit covers the full process and current Summit pricing.
Dryer Vent Cleaning in Summit
Lint buildup in dryer vents is a leading cause of house fires, and Summit’s longer vent runs through 1990s-era framing make thorough cleaning essential. We use Nikro equipment to pull lint from the full run, including rooftop terminations common in newer subdivisions. The 365-Day Done Right Promise covers this work too; if airflow doesn’t improve, we return at no charge. Dryer Vent Cleaning in Summit has the details.
Duct Sealing in Summit
Leaky ducts waste 20 – 30% of conditioned air in typical Summit homes, especially where flex connections have loosened at boots and plenums. We seal with mastic and mechanical fasteners, then verify with a pressure pan test. This matters most in Summit’s newer homes, where builders often prioritized speed over seal quality during the housing boom. Duct Sealing in Summit explains the full process and pricing.
