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 Mill Creek, WA
Air duct cleaning in Mill Creek, WA typically runs between $390 and $690 for a whole-home system, depending on square footage, the number of returns, and how long it’s been since the last cleaning. Mill Creek is a city where most homes were built between the late 1970s and mid-1990s, which means the ductwork in those houses is now 25 to 45 years old. That age range matters because it’s exactly when flex duct starts sagging, mastic seals crack, and accumulated dust becomes a real indoor air problem. Call us at (980) 447-2498 for a written quote before any work starts.
Why Mill Creek Homes Are Different
Mill Creek was built out almost entirely as a master-planned community, with subdivision phases going in from roughly 1977 through the mid-1990s. That means the housing stock is unusually uniform in age, and the forced-air systems in those homes are now decades old. We regularly see 1,800 to 3,200 square foot multi-level homes with flex duct running through unconditioned crawl spaces, a configuration that traps moisture and makes thorough cleaning more involved than slab-foundation homes with attic ductwork.
The Snohomish County climate adds another layer. Mill Creek gets roughly 35 to 40 inches of rain a year and holds high relative humidity from October through May. Damp air settles into ductwork, especially in crawl spaces under 1980s-era subdivisions where ground moisture lingers into summer. When flex duct sags or pools condensation, mold colonies can form and actively seed the air supply. The dense Douglas fir canopy throughout Mill Creek also drops organic debris that finds its way into outdoor air intakes and eventually into the system. That combination of aging ducts, persistent dampness, and heavy tree cover means annual or biennial cleaning is often the more defensible schedule here than the national 3 to 5 year recommendation.
Our Main Mill Creek Services
Most Mill Creek homeowners call us for one of two things: a full air duct cleaning or a dryer vent cleaning. A smaller number need duct repair, usually after a cleaning uncovers disconnected or crushed flex duct. Below are the three services we provide in Mill Creek, each with its own dedicated page.
Air Duct Cleaning in Mill Creek
Our Air Duct Cleaning in Mill Creek service uses negative-pressure extraction to pull accumulated dust, pet dander, and organic debris out of the entire supply and return system. In Mill Creek’s multi-level homes with crawl space duct runs, we pay particular attention to sagging flex duct and condensation pooling, which are common in 1980s subdivisions. Every register, return, and the main trunk line gets cleaned, and you receive a written price before we begin. No per-vent pricing, no surprise add-ons at the end.
Dryer Vent Cleaning in Mill Creek
Dryer Vent Cleaning in Mill Creek matters more than most homeowners realize, particularly in two-story and three-level homes where the dryer vent runs long distances to an exterior wall. Lint buildup in those extended runs is a documented fire hazard. We remove the lint trap bypass obstruction, clean the full vent run from the dryer to the exterior termination, and verify airflow at the outlet. In Mill Creek’s damp climate, we also check for moisture damage around the vent cap, which wet winter air can accelerate.
Air Duct Repair in Mill Creek
When a cleaning uncovers disconnected joints, crushed flex duct, or failed mastic seals, Air Duct Repair in Mill Creek addresses it directly. Homes in Mill Creek with crawl space ductwork are more prone to sagging and separation than attic-run systems, simply because gravity and ground moisture work against the duct over time. Every repair comes with a written guarantee and a free second visit if the repair fails within 365 days. We tell you what we found, show you photos, and quote the repair before touching anything.
