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 Mercer Island, WA
Air duct cleaning on Mercer Island costs between $350 and $600 for a typical single-system home, with larger custom builds running higher because of multi-zone ductwork and longer branch runs. What makes island jobs different from Bellevue or Seattle is the humidity: Lake Washington on all four sides keeps moisture in the air and in the ductwork year-round, so every visit includes a microbial and moisture check alongside the standard dust and debris removal. If you’re planning your first cleaning or replacing ducts after a remodel, call (323) 918-4345 and we’ll give you a written price before any work begins.
Why Mercer Island Homes Are Different
Most Mercer Island homes fall into two camps: original mid-century ranches and split-levels from the 1950s through 1970s, and large custom or gut-renovated homes from the 1990s onward. The older homes often carry partially replaced duct systems where galvanized trunk lines from the original build connect to newer flex-duct branches added during a remodel. Debris collects at those transition points, and a standard cleaning that stops at the register misses it entirely.
The island’s tree canopy – red alder, bigleaf maple, western red cedar – produces one of the heaviest combined pollen and organic-debris loads in the Seattle area every spring. Because homes sit close to the water table with lake humidity on all sides, that material enters supply runs already carrying moisture. The result is biofilm and mold formation inside ducts far faster than on the mainland. We inspect for microbial growth on every Mercer Island job, not just dust accumulation. In older west-side neighborhoods, we also check whether bathroom and kitchen exhaust fans were retrofitted into the supply plenum – a common shortcut that pushes grease and moisture directly into the duct system.
Our Main Mercer Island Services
Mercer Island homeowners most often call us for two jobs: whole-home air duct cleaning after a remodel or a long stretch without service, and dryer vent cleaning to clear accumulated lint in laundry rooms that run constantly for active families.
Air Duct Cleaning in Mercer Island
Whole-home air duct cleaning on the island means cleaning the supply and return plenums, every accessible branch run, and the registers in each room. Because of the elevated lake humidity, we spend extra time checking for moisture staining and early microbial growth inside supply runs, especially in lower-level rooms closer to the water table. Homes with multi-zone systems and long flex-duct branches take more time, but the process is the same: written price first, then the clean, then a photo of the clean-up before we leave. Air Duct Cleaning in Mercer Island is covered in detail on its own page, including what to expect on the day of service.
Dryer Vent Cleaning in Mercer Island
Dryer vent cleaning on Mercer Island matters more than people expect, because the same lake humidity that affects ducts also makes lint cling inside vent runs rather than blowing clear. Long vent runs in larger custom homes compound the issue, and blocked vents force dryers to work harder with every load. We clean the full run from the dryer connection to the exterior termination point, confirm airflow at the outside vent, and leave the laundry area clean. Dryer Vent Cleaning in Mercer Island has the full scope, typical timing, and what we check on the exterior vent cap.

Interior air duct cleaning does not require HOA approval on Mercer Island, since the work happens inside your home and does not touch shared walls or exterior finishes. If you live in a community with strict exterior access rules and your dryer vent terminates through a roofline or shared wall, we can coordinate the exterior portion with your property manager before we begin.
Yes. We clean original galvanized duct systems in mid-century homes and newer flex-duct branches in custom and rebuilt homes, and we pay particular attention to the transition points where old and new sections meet because that’s where debris collects. The written price reflects the actual system in your home, not a one-size-fits-all estimate.

What Mercer Island Customers Say
"Friendly, calm crew that clearly cared about the house. Covered their shoes, protected the floors, and double checked they'd closed up every vent cover properly. Would have them back."
- Omar Zaid"Ducts and dryer vent both. They put runners down the whole hall and wore booties. Spotless after, and they showed me photos of what came out. Worth every penny."
- Bonnie Vo"Spotless work. They laid drop cloths everywhere and I was honestly impressed there was zero mess at the end. Showed me the dirt they pulled out so I could see it was worth it."
