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 SeaTac, WA
Morton’s Air Duct Cleaning is the air duct and dryer vent specialist SeaTac families call when they want a written price before any work starts, professional equipment from brands like Nikro and Abatement Technologies, and a 365-Day Done Right Promise behind every visit. SeaTac homes sit under one of the nation’s busiest flight paths, which means ultrafine jet-exhaust particulates settle in ductwork here at concentrations you won’t find in Seattle, Tacoma, or Bellevue. That reality shapes how we clean, what we look for, and why a generic duct cleaning leaves SeaTac homes under-served. Call (323) 918-4345 for a free estimate.
Why SeaTac Homes Are Different
SeaTac’s residential core is largely mid-century single-family homes and garden-style apartment complexes built in the 1950s through 1970s to house airport and service-industry workers. Many still run original galvanized sheet-metal ducts. A good number of those homes were later modified under the Port of Seattle’s Residential Sound Insulation Program, which added new windows and supplemental HVAC components. The result is a patchwork system: original 1960s metal runs spliced to newer flexible duct at junctions that were never properly sealed. Those unsupported transitions are exactly where jet-particulate dust, pet hair, and construction debris accumulate.
SeaTac’s marine climate adds a second layer. Roughly 38 inches of annual rain and year-round high humidity keep moisture levels inside ductwork elevated. In homes with poorly sealed returns that draw damp crawlspace air, which is common in the area’s older pier-foundation and slab-edge construction, mold and mildew find favorable conditions inside the ducts themselves. A thorough cleaning here means addressing both the particulate load from aviation activity and the moisture-driven growth that follows.
Our Main SeaTac Services
SeaTac homeowners call us most often for two services, each with its own SeaTac page so you can see exactly what the job involves, what it costs, and how we leave your home.
Air Duct Cleaning in SeaTac
Air duct cleaning in SeaTac means removing layers of jet-particulate-laden dust, pet dander, and construction debris from supply and return runs that haven’t been fully opened in decades. Many homes inside the airport noise contour zones have Port of Seattle HVAC retrofits where new supply drops were added without ever sealing the connection to the original plenum. That gap collects years of fine dust and is nearly always overlooked. We inspect for those mismatched junctions, clean what’s there, and document everything with before-and-after photos.

Dryer Vent Cleaning in SeaTac
SeaTac’s older homes often have long dryer vent runs that snake through crawlspaces or exterior walls, collecting lint that stays damp in the marine air. That combination, restricted airflow plus persistent moisture, is what turns a routine dryer vent into a slow-drying, inefficient, and potentially hazardous run. We use professional equipment from brands like Rotobrush and Nikro to clear the full run from dryer connection to outside termination, then show you the photo before we leave.

In SeaTac, price climbs when homes have the Port of Seattle retrofit patchwork, those mismatched metal-to-flex junctions take longer to access and clean thoroughly. Homes with crawlspace-mounted ductwork or excessive moisture-related contamination also run higher because the work spans more surfaces. Whatever the job size, you’ll have a written price before our technicians begin, and the final invoice matches it.
