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 Redmond, WA
Air duct cleaning in Redmond, WA typically costs $350 – $650 for a whole-home system and is scheduled by appointment with a written price locked before work begins. Redmond’s damp, mild climate and aging 1980s – 1990s housing stock create distinct duct problems, biological growth and sagging flex duct, that dry-climate crews rarely encounter. We dispatch from our Seattle office and serve Redmond homes with Rotobrush rotary brush systems and Nikro negative-air machines, backed by the 365-Day Done Right Promise. Call (361) 326-5060 for a free estimate.
Why Redmond Homes Are Different
Redmond sits in the Puget Sound convergence zone, where year-round moisture, not seasonal dust, drives duct contamination. Rainy autumns and humid winters keep attic and crawl-space ductwork damp for months, promoting mold and microbial growth that dry eastern Washington rarely sees. Summer dryness is brief and mild enough that dust accumulation never fully bakes out the moisture cycle.
Much of Redmond’s housing stock dates to the 1980s and 1990s, built during Microsoft’s first expansion. Original builder-grade flex duct in neighborhoods like Education Hill and Redmond Ridge is now notorious for sagging between joists and disconnecting at joints. Those attic air leaks pull unconditioned air into the system, showing up as dust streaks around vents and energy bills that creep upward without explanation. Newer 2010s townhomes near Downtown Redmond present the opposite problem: complex multi-floor duct runs with tight access that require smaller rotary heads and patient disassembly.
Tech-worker households here often run IAQ sensors and expect photo documentation of before-and-after conditions. We accommodate that. The Garrison Code requires our crews to photograph every job, show the homeowner, and leave the images with the written invoice.
Our Main Redmond Services
Redmond homeowners call us most often for these three services, each with its own local conditions and equipment approach.
Air Duct Cleaning in Redmond
We clean supply and return ducts with a Rotobrush rotary brush system that scrubs the interior walls while a Nikro negative-air machine pulls debris downstream into a sealed collector. In Redmond’s damp climate, we pay particular attention to biological film on duct walls, not just loose dust. The rotary brush breaks it free; the negative-air method captures it before it enters your living space. We also inspect flex duct for sagging or disconnected joints, common in original 1980s – 90s construction. Air Duct Cleaning in Redmond
Dryer Vent Cleaning in Redmond
Dryer vent blockages in Redmond combine lint with moisture from the humid climate, forming dense, packed obstructions that pure lint alone doesn’t create. We use rotary brushes and high-velocity air tools to clear the full run from dryer to exterior cap, then verify airflow with a meter. Long vent runs in townhomes and multi-story builds are especially prone to trapping damp lint. Dryer Vent Cleaning in Redmond
Duct Sealing in Redmond
Duct sealing addresses the disconnected joints and sagging flex duct endemic to Redmond’s older subdivisions. We apply mastic sealant and mechanical supports at accessible leaks, then pressure-test the system to verify improvement. Sealing attic leaks in 1980s – 90s homes often delivers the most immediate comfort gain per dollar, especially when paired with cleaning. Duct Sealing in Redmond
