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 Seattle, WA
Air duct cleaning in Seattle runs $350 – $650 for most single-family homes, with dryer vent cleaning at $120 – $220 and full duct sealing at $1,800 – $3,200. What drives the price isn’t the room count; it’s the moisture load inside your ducts, the age of your system, and whether we’re working around original asbestos tape in a 1920s Craftsman or navigating tight crawlspaces in a new Ballard townhome. Call (361) 326-5060 and we’ll give you a written price before any work starts.
Seattle’s decades-long shift toward heat pumps and ductless mini-splits has left thousands of homes with hybrid HVAC systems where the original ductwork was sized for a gas furnace and now carries cooler, more humid air. That mismatch creates condensation inside metal trunk lines, especially in unconditioned crawlspaces, and it’s why duct cleaning here is as much about moisture management and mold prevention as it is about dust removal. Our crews see it weekly in neighborhoods from Wallingford to West Seattle: flexible ductwork sagging in standing water, blowing a musty odor that no filter will catch.
Why Seattle Homes Are Different
With over 150 rainy days per year and humidity that rarely drops below 70% in winter, Seattle’s climate turns ductwork into a condensation problem waiting to happen. Crawlspaces and attics stay damp year-round, and flexible duct runs in those spaces often sag where they shouldn’t, collecting water from poor site drainage. When we open a system in Ravenna or Crown Hill and smell that sharp, musty hit, we know we’re looking at mold growth that started with standing water, not household dust.
The housing stock makes it harder. Pre-1940 Craftsman bungalows dominate older neighborhoods, and their original ductwork is frequently undersized, leaky, and wrapped in asbestos tape that requires special handling. Mid-century ranches in Northgate and Lake City carry their own legacy: galvanized steel trunk lines with decades of corrosion at the seams. Newer infill townhomes in Ballard and Fremont have tight, complex duct runs designed for efficiency but prone to pressure imbalances that pull crawlspace air into living spaces. Every type demands a different approach, and none of them respond well to a one-size-fits-all cleaning.
Permit requirements are straightforward for cleaning work, but any repair or modification to ductwork in Seattle requires compliance with the Seattle Energy Code and may trigger inspection if asbestos-containing materials are disturbed. We handle the assessment and flag anything that needs permitting before we start.
Our Main Seattle Services
Seattle homeowners call us for three jobs that each have their own local challenges. Here’s what we handle and where to find the details.
Air Duct Cleaning in Seattle
We clean supply and return ductwork with rotary brush systems from Rotobrush and negative-air machines from Nikro, pulling debris out rather than blowing it deeper into the house. In Seattle, we pay special attention to moisture staining and mold indicators in crawlspace flex runs, and we document before-and-after conditions with photos you can see. Every job gets a written price upfront and our 365-Day Done Right Promise. Air Duct Cleaning in Seattle
Dryer Vent Cleaning in Seattle
Dryer vent blockages are a fire hazard and an efficiency killer, but in Seattle’s humid climate, lint also packs down with moisture into dense, stubborn clogs. We run professional augers and high-velocity air tools to clear the full run from dryer to exterior cap, including roof terminations common in older Seattle homes. We check airflow with a meter and show you the reading. Dryer Vent Cleaning in Seattle
Duct Sealing in Seattle
Leaky ducts in Seattle don’t just waste energy; they pull damp crawlspace or attic air directly into your living space, compounding mold and humidity problems. We seal accessible joints and seams with mastic and mechanical fasteners, then pressure-test the system to verify results. In homes with hybrid heat pump retrofits, proper sealing is often the difference between a system that controls humidity and one that cultivates it. Duct Sealing in Seattle
