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 Snohomish, WA
Air duct cleaning in Snohomish typically runs $350 – $650 for a whole-home system, with most jobs completed in a single visit. What sets Snohomish apart is the persistent river-valley fog and damp marine air that keeps indoor humidity elevated for weeks each fall and winter, making mold prevention and duct sanitization standard parts of the job here rather than add-ons. At Hollis Air Duct Cleaning, we dispatch from our Seattle office and serve Snohomish homes with Rotobrush rotary brush systems and Nikro negative-air machines, pricing every job in writing before we start. Call (361) 326-5060 for a free estimate.
Why Snohomish Homes Are Different
Snohomish sits in the Snohomish River Valley, where historic downtown and the riverfront hold Victorian and Craftsman homes built from the 1890s through the 1920s. Many still run on original unlined metal ductwork or gravity systems that have never been properly sealed. In these older neighborhoods, we regularly find decades of rodent debris, mold colonies, and disconnected runs that need careful sealing before any cleaning begins.
Up on the hillsides, 1970s – 1990s suburban tracts use flex duct that degrades faster in the damp climate. The marine air and frequent river fog push persistent moisture through crawl spaces and attics, so ducts here don’t just collect dust, they grow mold. Post-cleaning sanitization isn’t an upsell in Snohomish, it’s part of doing the job by the book under The Garrison Standard.
Our Main Snohomish Services
Most Snohomish homeowners call us for one of three jobs, each shaped by the local housing stock and climate conditions.
Air Duct Cleaning in Snohomish
We clean supply and return ducts with a Rotobrush rotary brush system that agitates debris loose, paired with a Nikro negative-air machine to pull it out of the house entirely. In Snohomish, we pay special attention to moisture-damaged flex duct in hillside homes and to sanitizing unlined metal systems in the historic district where mold is common. Every job gets a written price before we start and is covered by our 365-Day Done Right Promise. Air Duct Cleaning in Snohomish
Dryer Vent Cleaning in Snohomish
Dryer vent cleaning in Snohomish addresses lint buildup that restricts airflow and creates fire risk, especially in older homes with long vent runs through crawl spaces or walls. The damp climate here means lint can cake and stick rather than blow through cleanly. We clear the full run from dryer to termination, inspect for proper airflow, and note any damage in writing.

Duct Sealing in Snohomish
Duct sealing in Snohomish fixes the disconnected runs and gaps we find in both historic metal systems and aging flex duct. We use mastic sealant and metal-backed tape at joints, then pressure-test to confirm the seal holds. In the riverfront neighborhoods, this step often comes before cleaning, because pulling air through a broken duct just spreads debris through walls and crawl spaces. Duct Sealing in Snohomish
