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 Seattle
Air duct cleaning in Seattle usually costs between $450 and $900 for a full single-family home, depending on the number of vents and how much contamination is present. For most Seattle houses, the actual cleaning takes four to six hours with a two-person crew. We work in Seattle every week, and many jobs are booked within a week of the call.
You’re not buying a $79 coupon special that turns into a twelve-hundred-dollar invoice once someone starts opening panels. With CleanRun Air Duct Cleaning, you get a written price before any work begins. That’s Haven Standard Clause 1, and it’s been our policy since 2013, not a marketing line. Call (806) 606-6902 to get a real number in writing before you commit to anything.
Why CleanRun Air Duct Cleaning Is Seattle’s Preferred Air Duct Cleaning Company
Seattle homeowners call us because we publish our license number on every page, not buried in a footer. We show up with Rotobrush and Nikro equipment that anyone can look up online. We photograph the inside of every duct run before and after, so what you paid for is visible, documented, and yours to keep. That photo record has been part of every job since our first one in 2013.
We’ve pulled apart enough Ballard and Queen Anne systems to know that Seattle’s problem is rarely just dust. It’s moisture. It’s the crawl space acting like a steam room under your floor. A crew from a drier inland city might clean your ducts and call it done. We know that without addressing moisture at the source, mold returns before the next dry season. That’s why our Air Duct Cleaning process always includes a camera inspection of the duct runs most at risk from subsurface moisture.
Read any of our thousands of Seattle customer reviews and you’ll see the same phrases: “they showed me the photos,” “the price they quoted was the price I paid,” “they explained what was in there without pushing extras.” That’s the standard. That’s what we deliver in every Seattle home, from Capitol Hill to West Seattle.
Our Air Duct Cleaning Services in Seattle
Residential Duct Cleaning
A typical Seattle residence, especially the pre-1950s craftsman and 1940s-60s homes in neighborhoods like Wallingford and Fremont, often has ductwork retrofitted through crawl spaces that were never designed for forced air. That means residential cleaning here is a different job than it is in newer suburban builds. We clean every supply and return run, strip the registers, and camera-verify the work before we leave. You’ll see the inside of the ductwork, not just a receipt.
Commercial Duct Cleaning
For Seattle offices, clinics, and small retail spaces, we schedule around operating hours so the work doesn’t shut you down. Commercial systems in older Seattle buildings, many of which had heating retrofitted decades ago, accumulate the same crawl-space-driven contamination as homes, just at a larger scale. The process is the same: written scope, written price, documented photo evidence, no fogging upsell.
Supply Duct Cleaning
Supply ducts are the runs that deliver conditioned air from your furnace or heat pump to the room registers. In Seattle, supply runs are often routed through damp crawl spaces and unsealed joist cavities, which means they pull in moisture and whatever lives in that space. We clean these under negative pressure with HEPA filtration. When we finish, the supply side of your system is camera-inspected and photographed. What was in there is on the record.
Return Duct Cleaning
Return ducts pull air back to the air handler. In many older Seattle homes, return runs were never properly sealed to begin with, so they pull crawl-space air, rodent debris, and spores directly into the system. We find this constantly in houses near Green Lake and throughout Ballard. Return duct cleaning in Seattle is not optional if returns run through unconditioned space. We clean them, photograph them, and show you the joints that need sealing.
Video Inspection
Before we quote a job, we often run a camera through the supply and return runs. Not because we need to sell you on it, but because you deserve to know what’s actually in there, and so do we. A 3-inch debris build-up at a plenum is different from a collapsed flex run or an open joint drawing humid air into the envelope. The camera tells us which one we’re dealing with. You get the footage as part of our documented record.

BeforeAfterTrusted Brands We Service in Seattle
We service and clean systems built around Honeywell filtration, Aprilaire media cabinets, and standard forced-air components found in Seattle homes. Our rigs run Rotobrush and Nikro equipment, which matters less as a sales point than as a practical one: these tools use real negative-pressure extraction and HEPA filtration, not a shop-vac and a spinning brush attached to a drill. If you’re replacing a filter or upgrading filtration while we’re on site, we stock common sizes and can install them same-visit.
Common Air Duct Cleaning Problems We See in Seattle Homes
- Moldy flex duct and wet sheet metal in crawl spaces. Seattle’s marine climate pushes relative humidity above 80% for much of the overcast season, and crawl-space soil stays wet year-round. Duct runs in that space become constant condensation surfaces. By the time we open a panel, the ductwork is often actively growing mold, not just dusty.
- Retrofit duct systems that were never sealed properly. Homes in Ballard, Capitol Hill, and Beacon Hill that started with radiant heat and got forced air later often have non-standard routing through tight, humid crawl spaces. Open joints and unsealed seams draw that damp air straight into the living space.
- Rodent debris and nesting material in returns. Seattle’s rat population is a fact of urban life here. Return ducts that run through accessible crawl spaces are highways for them. We find nests, droppings, and chewed flex duct in returns more often than homeowners expect.
- The fogging upsell that doesn’t remove anything. Lots of Seattle duct cleaners push a “sanitizing fog” as an add-on. Fogging doesn’t remove physical mold, debris, or rodent contamination. Source removal under negative pressure does. In Seattle’s chronically damp ducts, fogging can add moisture and make things worse.
Pricing for Air Duct Cleaning in Seattle, WA
For a single-family Seattle home with up to 12 vents, a full residential duct cleaning typically runs $450 to $700. Larger homes, or homes with significant mold or rodent contamination, run $700 to $900. Commercial spaces are quoted by scope, not per vent. You will not be charged per vent. You will not be quoted a teaser price that changes when the van pulls up.
Every Seattle job includes: a written price before work starts, HEPA negative-pressure extraction, camera inspection of every duct run, before-and-after photos, and the 365-Day Done Right Promise in writing. That’s not a warranty subject to manager approval. It’s our contract with you.

FAQs - Air Duct Cleaning in Seattle
Because the crawl space under your Seattle home is a year-round humidity chamber. The marine climate keeps relative humidity above 80% through most of the cool season, rainfall averages 37 to 38 inches a year, and the soil stays damp for months. Duct runs in that space absorb that moisture constantly. A standard cleaning that only removes surface dust, or one that adds moisture through fogging, does nothing to change the humidity at the duct’s exterior surface. Within one rainy season, the mold is back. A genuine Seattle duct cleaning has to address that context, not just the dust inside the run. Call (806) 606-6902 to get a written assessment.
It’s an upsell, and in Seattle it can be a harmful one. Fogging applies a mist, and in ducts already sitting in chronically humid air, adding moisture to the interior can accelerate microbial growth. Fogging does not remove physical mold, rodent debris, or built-up contamination. Source removal, meaning extraction under negative pressure with HEPA filtration, removes the material. That’s what we do, and you see the before-and-after photos. Haven Standard Clause 2: Documented Evidence. Get a real quote by calling (806) 606-6902.
Older Seattle homes in neighborhoods like Fremont, Wallingford, and Capitol Hill were frequently built with radiant or baseboard heat, not forced air. Forced-air ductwork was retrofitted later, often routed through tight crawl spaces and unconditioned areas, and sealed poorly by modern standards. Those non-standard runs sit directly in Seattle’s perpetually damp soil air, collect condensation, and draw in rodent traffic and spores. Newer homes have sealed, insulated duct runs in conditioned space. The difference is visible on camera every time. We inspect your specific system and tell you what’s actually there.
In a dry inland city, duct cleaning is mostly about accumulated dust and debris. In Seattle, duct cleaning is equally about moisture. Our marine climate means your ducts are sitting in humid air for most of the year, especially if they run through a crawl space. That changes what a real cleaning has to accomplish. It means source removal under negative pressure, a moisture assessment, sealing recommendations for open joints, and often a crawl-space encapsulation recommendation. If a company cleans only the visible registers and doesn’t talk about where your ducts live, they’re selling a partial service in this city. We’ll put it in writing after a camera inspection. Call (806) 606-6902.
Yes, if the smell is coming from contaminated ductwork, which it often is in Seattle. The winter smell is typically microbial growth and decay in the ducts or the crawl space beneath them, and the forced-air system distributes that odor through the house every time the heat kicks on. Cleaning the duct runs removes the physical source. If the crawl space itself remains wet, the smell can return, which is why we always inspect and recommend encapsulation where it’s needed. You’ll get the camera footage to see exactly what’s down there. Call (806) 606-6902 to book a written-price assessment.
