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 Mill Creek, WA
Air duct cleaning in Mill Creek typically runs $350 – $650 for a whole-home system, with most jobs scheduled within a week and completed in three to five hours. Mill Creek’s 1970s – 1990s planned-community homes, with their flex duct runs in unconditioned attics and original builder-grade foil-tape joints, create a distinct set of problems we don’t see in newer construction markets. We’re Hollis Air Duct Cleaning, part of the Garrison Partners family, and our crews handle the seasonal surge that hits every October when HOA-mandated re-roofing dumps fine sawdust into return systems across the Country Club and Town Center tracts. Call us at (361) 326-5060 for a written estimate before any work starts.
Why Mill Creek Homes Are Different
Mill Creek sits in the Puget Sound lowland where cool, wet winters and dry summers mean furnaces sit idle for months, then fire up in October to blow out whatever accumulated in the ducts. The original 1980s Country Club neighborhood and the Town Center-adjacent tracts were built as master-planned communities with heavy HOA oversight, and that structure creates a unique work pattern: synchronized exterior renovations, especially roof replacements, generate a predictable wave of post-construction duct cleaning calls each fall.
The housing stock tells the rest of the story. Most homes are two-story builds from the 1970s through 1990s with forced-air gas furnaces and flex duct runs snaking through unconditioned attics. Original foil-tape joints degrade after twenty-plus years, and fiberglass duct board breaks down where it counts. Newer Town Center condos add their own wrinkle with shared vertical chases that need special containment so debris doesn’t migrate to neighboring units. We also see rodent debris and mold in the damp crawlspaces common to Mill Creek’s split-levels, especially after the wet season.
Our Main Mill Creek Services
Mill Creek homeowners call us for three jobs, each with its own page and pricing.
Air Duct Cleaning in Mill Creek
We clean the full supply and return system with a Rotobrush rotary brush and Nikro negative-air machine, pulling debris out rather than pushing it deeper. In Mill Creek, the fall re-roofing season means we regularly find fine sawdust coating blower wheels and evaporator coils in Country Club homes. We contain the work zone, run the system, and show you before-and-after photos from your own ducts. Air Duct Cleaning in Mill Creek covers full pricing and what the visit includes.
Dryer Vent Cleaning in Mill Creek
Dryer vent blockages are a fire risk, and Mill Creek’s older two-story homes often have long vent runs through attics or sidewalls that trap lint where homeowners can’t reach. We clear the full run from back of dryer to exterior termination, test airflow with a manometer, and flag any foil or plastic transition hose that needs replacing with solid metal. Dryer Vent Cleaning in Mill Creek has the full breakdown.
Duct Sealing in Mill Creek
Leaky ducts in unconditioned Mill Creek attics waste heated air every winter and cooled air every summer. We seal accessible joints with mastic and mechanical fasteners, then pressure-test to verify the seal holds. This matters especially in the original planned-community builds where foil tape has dried out and separated at the plenum connections. Duct Sealing in Mill Creek explains the process and what improvement to expect.

FAQs About Air Duct Cleaning Company in Mill Creek
Most Mill Creek HOAs don’t mandate duct cleaning directly, but they do mandate synchronized re-roofing schedules. The fine sawdust from cutting roof sheathing gets pulled into return air systems, so we see a predictable wave of homeowner-initiated cleanings each October through November. Call (361) 326-5060 if your roof was replaced this season and your furnace smells like sawdust on first fire-up.
Standard appointments typically book within five to seven days. Fall re-roofing season can stretch that to ten days in October and November. We don’t overbook; if we say we’ll arrive between 8 and 10 a.m., we arrive inside that window. Call (361) 326-5060 for current availability.
Yes, but with special containment protocols. Shared vertical chases in multi-unit buildings require sealed work zones and negative-air isolation so debris doesn’t migrate to neighboring units. We assess the chase configuration during the estimate and price it in writing before starting.
