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 Renton, WA
Air duct cleaning in Renton costs more than it does in Bellevue or Auburn for a reason most homeowners never hear: the city sits at the bottom of a valley bowl, and that bowl collects everything. The Boeing plant, the I-405 and SR-167 interchange, and the Cedar River all converge on the valley floor where most Renton homes stand. Wildfire smoke funnels in from Eastern Washington every late summer and settles into the bowl, then gets pulled through return vents and packed into ductwork. We clean ducts in Renton because the air here works harder against the people breathing it. Call us at (469) 972-3151 for a written quote before anyone touches a vent.
Why Renton Homes Are Different
Most of Renton’s core residential streets, from the Highlands down through Earlington and Benson Hill to the flats near downtown, were built during the Boeing employment boom of the 1950s through the 1970s. Those ramblers and split-levels went up fast, and a lot of them still run their original sheet-metal ductwork. Fifty or sixty years of high-humidity cycling leaves that metal corroded, and corrosion gives dust and biofilm something to grip. Combine that with roughly 40 inches of annual rainfall, persistent morning fog, and ground-level temperature inversions, and moisture becomes a recurring character in crawlspace-routed duct systems all across Renton’s valley floor.
The terrain shapes the work too. Technicians working the lower Cedar River flats regularly open supply lines and find flex duct runs saturated or visibly molded, not from any HVAC leak but from groundwater events tied to the river. Even a near-miss flood year pushes moisture up into crawlspaces and from there into the ducts themselves. That pairing, mold remediation and duct cleaning as one job, comes up constantly in Renton and almost never in neighboring plateau cities on higher ground.
Our Main Renton Services
Renton homeowners call us most often for two jobs: full air duct cleaning for the home’s heating and cooling system, and dryer vent cleaning to clear the exhaust path that runs from the dryer to the outside. Each has its own Renton page with local pricing and specifics.
Air Duct Cleaning in Renton
Full-system Air Duct Cleaning in Renton starts with a camera inspection of the supply and return lines, then runs a rotary brush system through every trunk and branch to dislodge debris at the duct wall. A negative-pressure unit pulls the loosened material out of the house while HEPA filtration keeps it from re-entering the living space. In Renton’s older ramblers, we’re often removing decades of accumulated Boeing-era dust, pet dander, and smoke particulate that settled into ducts that have never been opened. The written price is in your hands before we start.
Dryer Vent Cleaning in Renton
Dryer Vent Cleaning in Renton clears the full exhaust path from the dryer’s lint trap bypass to the vent termination outside. In Renton’s split-levels and Benson Hill ramblers, those runs are often long, with multiple elbows, and they collect lint at every bend. That buildup forces the dryer to work harder, wastes energy, and creates a fire risk. We clean the entire run, not just the first few feet, and we show you what came out before we leave.

What Renton Customers Say
"Bought an older home and the previous owners had pets everywhere. After Kestrel did the ducts the stale smell was just gone. On time, quick, and they showed me the filter they pulled."
- Preston Ngata"Our dryer was taking two cycles to dry a load. They cleaned the vent and pulled out a frightening amount of lint. Dries in one cycle now and honestly I feel better about the fire risk."
- Marcus Lee"Set up an appointment for the whole house plus the dryer line. They called the morning of to confirm, showed up in the window, and showed me pictures of the gunk they pulled out. Worth it."
