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 Lake Stevens, WA
Air duct cleaning in Lake Stevens typically runs $350 – $650 for a whole-home system and is best scheduled in fall before the heating season starts. The city’s damp Puget Sound climate and abundance of 1990s – 2000s subdivisions create a specific problem: moisture-driven mold, mildew, and dust-mite buildup inside ductwork that dry-climate cities simply don’t face. At Hollis Air Duct Cleaning, we dispatch crews from our Seattle office to handle Lake Stevens jobs with equipment built for biological contamination, not just dust removal. Call (361) 326-5060 for a free written estimate.
Why Lake Stevens Homes Are Different
Lake Stevens sits in the Puget Sound lowlands where wet, mild winters and high year-round humidity keep duct interiors damp enough for mold and dust mites to thrive. Most homes here are 1990s – 2010s two-story suburban builds with forced-air systems, but older pockets near downtown and the lakefront hold 1960s – 70s ranchers with original galvanized or flex duct prone to rust and rodent intrusion from nearby wooded ravines.
In the newer east-side subdivisions, we regularly find builder-grade flex duct crushed or disconnected at the plenum, causing uneven heating that homeowners mistake for a furnace problem. Many of these systems are still under builder warranty, so our technicians document everything and work carefully to avoid voiding coverage. The Garrison Code requires us to leave the site clean, arrive inside the quoted window, and put the price in writing before any equipment runs.
Our Main Lake Stevens Services
Most Lake Stevens homeowners call us for one of three jobs, each with its own page and pricing.
Air Duct Cleaning in Lake Stevens
We clean the full supply and return network using a Rotobrush rotary brush system or Nikro negative-air machine, depending on duct material and contamination level. In Lake Stevens, this often means removing mold and mildew colonies that grow in damp fiberglass-lined duct, not just surface dust. We photograph the before and after so you see what came out.

Dryer Vent Cleaning in Lake Stevens
Lake Stevens’ humid air means lint clings to vent walls longer and packs denser, especially in two-story homes with long horizontal runs through unconditioned crawl spaces. We clear the full run from dryer to termination, check backdraft dampers for corrosion, and measure airflow before and after. Dryer Vent Cleaning in Lake Stevens
Duct Sealing in Lake Stevens
Crushed flex duct and disconnected plenum joints in newer subdivisions leak heated air into attics and crawl spaces. We seal accessible seams with mastic and mechanical fasteners, then pressure-test to verify the fix. This is often the real solution when a room won’t heat evenly, not a bigger furnace.

FAQs About Air Duct Cleaning Company in Lake Stevens
No permit is required for standard cleaning or sealing. If we find rodent-damaged duct needing section replacement in an older home, we flag it and advise whether the scope crosses into permit territory. Call (361) 326-5060 and we’ll walk through your specific situation.
Properly performed cleaning does not void warranties. Our technicians document pre-existing conditions, use tools rated for residential duct, and avoid cutting or modifying sealed assemblies. If your home is still under builder coverage, tell us when you call and we note it on the work order.
We typically book 3 – 5 days ahead in peak fall season, 1 – 2 weeks in winter when heating problems spike. Phones are answered by a live person 24/7, so you can reserve a slot evenings or weekends without waiting for a callback. Call (361) 326-5060 to check current availability.
