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 Renton
Air duct cleaning in Renton costs between $390 and $780 for a full system clean of a typical single-family home, with older Boeing-era houses on the valley floor running higher because of mold remediation work. Most jobs take four to six hours and come with something you won’t get from a $79 coupon outfit: a camera record of every duct run before and after the work. That matters in Renton specifically. Our crews work neighborhoods from the Rainier Avenue corridor up to the Highlands plateau, and we know what this valley’s trapped moisture does to ductwork. Call (806) 606-6902 for a written price before any work starts.
Why CleanRun Air Duct Cleaning Is Renton’s Preferred Air Duct Cleaning Company
Renton homeowners call CleanRun because we hand them a written price before a single panel comes off. That’s Haven Standard Clause 1, and it has been how we’ve operated since 2013 across 52,000+ homes. No exceptions, no “call for a quote” runaround. Every job ends with a Documented Photo Record showing the inside of each duct run before and after, so you can verify what actually changed. Tomas Reyes, who leads our crews, puts his name on that record.
Our technicians are background-checked, uniformed, and identified by name before arrival. We response to service calls across Renton including the Highlands, Kennydale, Cascade, and the neighborhoods around Renton Technical College. The equipment we run is from trade-recognized manufacturers: Rotobrush agitation tools, Nikro negative-air machines, Abatement Technologies HEPA filtration, and Guardsman antimicrobial treatments. You can look those brands up yourself before we arrive. We’d rather you did.
The 365-Day Done Right Promise backs every job in writing. If it’s not done right, we make it right. Not a policy subject to manager approval. A written guarantee that follows the work.
Our Air Duct Cleaning Services in Renton
We perform Air Duct Cleaning across the full spectrum of duct systems found in Renton homes, from 1940s sheet metal to early flex duct to the tighter modern systems up on the plateau. Here’s what we cover.
Residential Duct Cleaning
A residential clean in Renton means pulling every register, running negative-pressure extraction through supply and return sides, and documenting the result. In older valley-floor homes, this almost always includes removing accumulated debris that has wicked moisture from crawl spaces. We seal what we can reach and photograph what we can’t.
Commercial Duct Cleaning
Renton’s commercial spaces along Grady Way, Rainier Avenue, and the Southport waterfront area have a different set of problems: high-occupancy turnover, rooftop units pulling damp night air, and longer duct runs that collect fine particulate. We clean after hours or during scheduled shutdowns, and every project gets the same documented photo record as a single-family home.
Supply Duct Cleaning
Supply ducts are the pressurized side of the system, pushing conditioned air into rooms. In Renton’s humid valley conditions, supply ducts in unsealed crawl spaces pull in ground moisture through microscopic gaps. We clean them under negative pressure and identify where sealing is needed so the air moving through them isn’t re-contaminated the next week.
Return Duct Cleaning
Return ducts are where this city’s persistent low-level fog does its quiet work. Air gets pulled back to the air handler through these runs, and in mid-century Renton homes they often route through damp, unconditioned spaces. We gave return duct cleaning extra emphasis because skipping it means the same spore load keeps recirculating through the air handler into every room. We inspect, clean, and photograph both sides.

BeforeAfterTrusted Brands We Service in Renton
We service duct systems connected to equipment from Honeywell, Aprilaire, and Guardsman, among others. If your Renton home has a Honeywell whole-house filtration unit or an Aprilaire humidifier or dehumidifier, we’ll work around it and tell you what the ductwork on either side of it actually looks like. We don’t install these units, but we understand how they integrate with the duct runs we’re cleaning, and we won’t damage them in the process. If a component is older and underperforming, we’ll show you the photo evidence and let you decide.
Common Air Duct Cleaning Problems We See in Renton Homes
Renton’s specific geography creates a predictable set of duct problems. Here’s what our crews encounter most often:
- Mold in valley-floor flex duct runs. Homes built between the 1940s and 1970s in the Cedar River drainage often have flex duct sitting just a few feet above damp ground. Moisture wicks through the outer sheath, and colonies form inside the air stream. This is a Renton-floor problem, not a Renton-plateau problem.
- Rust-through seams in original sheet metal. Older metal ductwork near the river lowlands corrodes at the seams. Once a seam opens, ground moisture and spore-laden air enters the system regardless of how clean the interior surface is. Camera inspection catches this, which is why we don’t skip it.
- Musty smell that returns after a “sanitizing” fog. Fogging without source removal leaves wet dust and mold colonies caked on duct walls. In Renton’s humidity, regrowth happens within weeks. Source removal is the only thing that breaks the cycle.
- Particulate buildup from topographical stagnation. The bowl-shaped valley traps fine particulate, pollen, and fog droplets for longer periods than higher-elevation neighboring cities. Supply and return ducts here accumulate faster than in Bellevue or Issaquah, even in homes with decent filtration.
Pricing for Air Duct Cleaning in Renton, WA
Here are honest numbers for the Renton market. A full system clean of a typical single-family home in Renton runs $390 to $480 when the ductwork is in reasonable shape. Homes with accessible crawl-space ducting, multiple returns, or secondary registers run $450 to $680. Older Boeing-era tract homes on the valley floor where our camera inspection finds mold or moisture intrusion run $520 to $780, because the job now includes source removal, seal work, and antimicrobial treatment with Guardsman product. A video inspection alone is $99, and we credit that amount toward the full cleaning if you proceed. Every price is written down before work starts. No exceptions. If you have a competitor’s written estimate, we’ll put our number next to it at no cost.

FAQs - Air Duct Cleaning in Renton
Because the valley floor near the Cedar River holds groundwater just a few feet below the surface, and that moisture moves upward into crawl spaces and the ductwork running through them. Homes on the Renton Highlands plateau sit higher, with drainage that pulls water away from the foundation. The result is a measurable difference in duct wall moisture: valley-floor homes show condensation and microbial growth far more frequently than plateau homes. If your house is in the lower elevations around Rainier Avenue or downtown Renton, mold remediation is a standard part of a proper duct clean here, not a rare add-on. Call (806) 606-6902 for a written price that includes whatever your ducts actually need.
Fogging alone doesn’t clean mold out of ducts. A fogger disperses antimicrobial mist that settles on surfaces, but it doesn’t remove the underlying biomass: the wet dust, the spore colonies, the organic debris glued to the duct wall. In Renton’s humidity, that biomass holds enough moisture for mold to regrow through the residual antimicrobial layer within weeks. What actually works is source removal: mechanically agitating the duct walls under negative-pressure HEPA filtration so the material is extracted from the system entirely, then applying an antimicrobial like Guardsman to the now-clean surface. That combination is what breaks the cycle. If someone offers you a $99 fog-only service, ask them what they’re removing from the duct. The answer will tell you everything.
Yes. In a 1963 tract home off Rainier Avenue near downtown Renton, our crew pulled back a musty crawl-space access panel to find the original flex duct runs sitting barely three feet above the Cedar River floodplain. The insulation wrap was soaked with ground moisture wicking through the outer sheath, and our camera inspection showed speckled mold colonies inside the supply ducts. We ran Rotobrush agitation tools under negative pressure with HEPA filtration to source-remove the growth and debris, then sealed the duct seams. The homeowner said the persistent “basement smell” upstairs cleared within a day. No sheet metal was torn out. We work through registers and existing access points, and every run gets photographed before and after.
Every three to four years is a reasonable interval for Renton homes given our valley humidity, and closer to three if your house sits on the valley floor near the Cedar River drainage. Homes on the Highlands plateau with modern forced-air systems can usually go four to five years. The real determinant isn’t a calendar, it’s what the inside of the duct looks like. Camera inspection settles the question in five minutes. Call (806) 606-6902 and we’ll show you.
If the smell is coming from mold or biological material inside the duct runs, yes, a proper clean of both supply and return sides will reduce it. Return ducts are often the source because they pull air from the house into the system, and in Renton’s damp crawl spaces that air carries moisture that condenses inside the return run. Cleaning supply ducts while ignoring returns means the same material keeps recirculating. We emphasize Full System Cleaning and Video Inspection on this page because Renton’s humidity makes partial cleans particularly ineffective. If the smell persists after a full clean, the source is likely in the crawl space itself, and we’ll show you the video evidence so you know exactly what and where it is.
