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 Forest Park, WA
Air duct cleaning in Lake Forest Park runs $350 – $650 for a typical single-system home, with most jobs scheduled within a week and completed in one visit. Lake Forest Park’s heavy tree canopy and moist marine climate create a unique combination of high indoor humidity, organic debris, and pollen that accelerates duct contamination faster than in drier Puget Sound cities. We’re Hollis Air Duct Cleaning, and our crews work these wooded lots regularly, from the 1960s ranches near Lake Washington to the split-levels tucked into the hills above Lyon Creek. Call (361) 326-5060 for a written estimate before any work starts.
Why Lake Forest Park Homes Are Different
Lake Forest Park sits under one of the densest tree canopies in the Seattle metro, and that changes everything about what’s inside your ducts. With over 40 inches of rain annually, mild humid winters, and abundant evergreen pollen, HVAC systems here face near-constant moisture and biological particulate loads. The housing stock is predominantly 1960s – 1980s ranch and split-level homes on large wooded lots, many still running original galvanized or early flexible ductwork that traps debris and supports microbial growth in the damp environment.
After a windstorm, cedar and fir needles pile up on roofs and often get drawn into outdoor air intakes. We regularly find needle debris clogging return ducts along the ridge above Lake Washington, something that rarely happens in cleared suburban developments to the south. The Garrison Standard means our technicians check these intakes as part of every job, not as an add-on.
Our Main Lake Forest Park Services
Most Lake Forest Park homeowners call us for one of three jobs. Each has its own page with full pricing and technical detail.
Air Duct Cleaning in Lake Forest Park
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 Forest Park, we often pull out compacted fir pollen and fine organic dust that standard shop vacuums won’t touch. Every job gets a written price before we start and is covered by our 365-Day Done Right Promise. Air Duct Cleaning in Lake Forest Park
Dryer Vent Cleaning in Lake Forest Park
Dryer vents in Lake Forest Park clog faster than average because of the dense tree cover and humid air that keeps lint sticky. We run a rotary brush through the full vent line to the exterior cap, check airflow with a meter, and verify the dryer’s internal lint trap housing is clear. If the vent fails within a year, we come back free. Dryer Vent Cleaning in Lake Forest Park
Duct Sealing in Lake Forest Park
Older galvanized and early flexible ductwork in Lake Forest Park homes leaks conditioned air into attics and crawl spaces, driving up heating bills and pulling in musty air. We apply duct sealing mastic and mechanical fasteners at joints and seams, then pressure-test the system to confirm the seal holds. Duct Sealing in Lake Forest Park
