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.

AfterFast, Reliable Air Duct Cleaning Across Kent
Air duct cleaning in Kent usually runs $390-$890 for a full single-family system, and most jobs take four to seven hours depending on how many returns and the age of the duct board. If you live in an East Hill home built between 1978 and 1998, you’re likely dealing with flex-duct runs that have sagged, trapped condensation, and grown biological material that a standard vacuum pass won’t touch. That’s the reality of Kent’s housing stock, and it’s why our crews arrive with camera inspection gear, not just a rotating brush. Call (806) 606-6902 and we’ll give you a written price before a single panel comes off.
Why CleanRun Air Duct Cleaning Is Kent’s Preferred Air Duct Cleaning Company
Kent homeowners keep calling us back because we show them what’s actually inside their ducts. Every visit includes a Documented Photo Record: the inside of every duct run, photographed before and after, delivered as part of the standard job record. No other company serving Kent makes that a standard deliverable, and it changes the whole conversation. You don’t take our word for it. You look at the photos.
We’re independently owned and operated under the Haven Standard, established in 2013. Our technicians are background-checked, uniformed, and identified by name before they arrive. That matters in Kent, where so many homes sit on crawlspaces and slab foundations that hide duct damage for decades. We’ve serviced over 52,000 homes, and every single one got a written price before work started. That’s Haven Standard Clause 1, and it’s not negotiable.
Our Air Duct Cleaning Services in Kent
Residential Duct Cleaning
Most Kent homes we clean are 3-4 bedroom tract builds on East Hill with gas forced-air furnaces and flex-duct distribution systems now pushing 30 to 40 years old. We clean the full run: supply ducts, return ducts, plenum, and registers. In Kent’s Green River Valley, where October-to-May moisture pools longer than in Renton or Federal Way, we pay particular attention to return-air ducts pulling unconditioned crawlspace air. That’s where mold colonizes first.
Commercial Duct Cleaning
Kent has a dense commercial corridor along 84th Avenue South and the industrial stretches near the Green River. We clean duct systems in offices, retail spaces, and light industrial buildings. Commercial work in Kent often involves longer duct runs and rooftop units, which means more elbows and more places for debris to sit. We schedule commercial jobs with written timelines so you’re not guessing when the crew finishes.
Supply Duct Cleaning
Supply ducts in Kent’s older homes carry dust, drywall particulate, and sometimes insulation fibers from attic runs. In East Hill homes with minimal support strapping, supply ducts often sag at the midpoint between supports. That sag becomes a debris trap. Our negative-pressure extraction with agitation tools reaches those low spots, not just the straight runs a shop-vac can handle.
Return Duct Cleaning
Return ducts are the problem child in Kent. Returns in 1980s and 1990s East Hill homes are frequently undersized, which means they pull harder and bring in more unconditioned air from crawlspaces. That air carries moisture, and the moisture condenses on fiberglass duct board. We clean returns with HEPA-filtered negative pressure and camera-inspect every return before we call it done. If the flex core has delaminated, we document it and tell you straight: cleaning won’t fix this one; replacement will.

Common Air Duct Cleaning Problems We See in Kent Homes
- Sagging flex-duct runs in East Hill homes built 1978-1998. The flexible duct used in that era had minimal support strapping, and after 30-plus years it sags at the midpoint. Those low spots trap standing debris and condensation. A basic brush-and-vacuum can’t reach them; you need agitation tools and camera verification.
- Mold blooms in return ducts fed by crawlspace air. Kent’s position on the Green River Valley floor means marine moisture and valley fog persist longer than in the upland cities around us. Any return leak pulling air from a crawlspace introduces that moisture into fiberglass duct board, and the result is recurring biological growth.
- Heavy dust loading in mid-century ranch homes near historic downtown Kent. Those rigid metal duct systems have just been collecting dust for 50-plus years. The runs are often fully sealed and impossible to inspect without a camera, so owners assume they’re clean when they’re carrying decades of particulate.
- Post-flood water trapped in low spots. After Green River or stormwater flooding reaches a crawlspace, water sits in the lowest sag of the duct run. Brush cleaning the visible portion leaves that water in place. Within weeks the mold comes back, and the homeowner ends up replacing the run anyway.
Pricing for Air Duct Cleaning in Kent, WA
Here’s what we write on the estimate, in dollars, before any work starts. A standard single-family home in Kent with 8-12 duct runs typically runs $390-$590. Larger two-story East Hill homes with multiple returns and a full crawlspace system run $590-$890. If you’ve had a flood or water intrusion that requires sanitizing after cleaning, add $150-$300 for antimicrobial application and HEPA air-scrubbing during the job. Video inspection is included on every job, not sold as an add-on.

FAQs - Air Duct Cleaning in Kent
It depends on whether the duct material absorbed water or just got wet on the surface, and the only way to know is camera inspection. Flex-duct with a delaminated inner core or fiberglass duct board that has been soaked through cannot be cleaned back to safe condition; it must be replaced. We document what the camera shows and give you a written finding, and we’ve had Kent homeowners’ insurers accept those findings as evidence for replacement coverage. Call (806) 606-6902 and we’ll schedule the inspection.
Because the flex-duct systems installed during that construction boom were built with minimal support strapping, and they’ve spent 30 to 40 years sagging, trapping condensation, and pulling in moisture from the Green River Valley’s persistent marine air. Newer homes on the plateau typically have better-supported rigid duct or at least tighter connections. East Hill homes from that era reliably need cleaning every 3 to 4 years, not because the occupants are messy, but because the duct geometry fails over time.
We run a video inspection of every duct run and the air handler, capturing the water line, the material condition, and any biological growth. The footage and stills go into a written report with our findings and a recommended remediation path. When the damage is from a covered event, that documentation is what an adjuster needs to process a replacement claim instead of a cleaning claim. We’ve done this for homes in the valley and on East Hill after stormwater events.
The registers are the exit point, not the storage point. The dust, debris, mold, and condensation live inside the duct runs themselves, often in the sags and elbows far from the visible register boot. Cleaning only the registers makes the visible part look better for a week. The biological load inside the run keeps recirculating through the house. In Kent’s humid valley air, that’s not a cosmetic issue; it’s a respiratory irritant that compounds year over year.
Yes, if the duct board is intact and the mold is surface-level. Source removal with HEPA-filtered negative pressure and proper agitation tools, done to NADCA standards, can remove surface mold from intact fiberglass duct board. If the board is delaminating, crumbling, or has absorbed moisture through its full thickness, no cleaning method will restore it. That’s when we tell you replacement is the only option, and we’ll show you the video that proves why.
