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 HVAC Cleaning Across Kent
HVAC cleaning in Kent, WA typically runs $380-$690 for a full system clean that includes the evaporator coil, blower motor, air handler interior, and all accessible duct runs. Most jobs take 3-5 hours on a single system, and we schedule Kent appointments within the same week. Call (806) 606-6902 for a written price before any work starts.
We know Kent’s housing stock because we work it every week. East Hill tract homes, Panther Lake splits, the older ranch neighborhoods down near historic downtown. The systems are different, the failure patterns are different, and the fix is different. That’s why a generic duct cleaning from a coupon company doesn’t hold up here. We’ll show you the before-and-after photos so you can verify the work yourself.
Why CleanRun Air Duct Cleaning Is Kent’s Preferred HVAC Cleaning Company
CleanRun has cleaned HVAC systems in Kent since our earliest days, and the work here shaped how we document every job. The East Hill subdivisions keep us honest: when a 1992 flex-duct system has sagged and collected condensation, you can’t claim the ducts are clean unless you can show the camera footage. So we photograph every duct run before and after, every time, and those photos are part of your job record. No other HVAC cleaning company in Kent hands you that documentation as a standard deliverable.
Homeowners in Kent consistently tell us the same thing: they researched three or four companies, saw the same generic promises, and called us because we publish our pricing structure and our method instead of hiding behind a “free inspection.” That’s Haven Standard Clause 1 at work: a written price before a single panel comes off. Tomas Reyes, our owner, built CleanRun on that principle in 2013, and it has held for every one of the 52,000+ homes we’ve served since.
Our HVAC Cleaning Services in Kent
Evaporator Coil Cleaning
In Kent’s Green River Valley humidity, evaporator coils grow biofilm faster than in drier upland cities. A coated coil loses heat transfer, forces the compressor to run longer, and pushes musty air through the house. We remove the coil, clean it with professional-grade cleaners, and photograph it before and after. A typical evaporator coil clean in Kent runs $180-$320 as part of a full system job, or $220-$380 standalone depending on access.
Air Handler Cleaning
The air handler is where Kent’s moisture problem concentrates. Condensation from the coil drips into the drain pan, and in a humid valley climate that pan becomes a mold source that the blower then distributes. We open the handler, clean the cabinet interior, the drain pan, the coil housing, and treat the components. Air handler cleaning in Kent typically adds $120-$200 to a full system clean.
Blower Cleaning
A dirty blower wheel throws captured dust and mold spores back into freshly cleaned ducts within weeks. That’s why we never clean ducts without addressing the blower. On Kent East Hill homes especially, where sagging return ducts pull unconditioned crawl space air, the blower picks up fine particulate that cakes onto the wheel blades. Blower cleaning in Kent runs $90-$150 when done with a system clean; it’s the single most overlooked step in the entire category.
Condenser Cleaning
The outdoor condenser unit collects cottonwood, grass clippings, and road dust from Kent’s summer construction traffic. A clogged condenser coil raises head pressure and shortens compressor life, which in a $6,000-$12,000 system is not a repair anyone wants. We clean condenser coils with low-pressure water and fin-safe detergent. Condenser cleaning in Kent runs $120-$200, and we’ll tell you honestly if yours doesn’t need it yet.

We work on every major residential HVAC brand found in Kent homes: Carrier, Trane, Lennox, Rheem, Goodman, York, and Bryant, plus older equipment from the 1980s and 90s that’s still running on East Hill. On the cleaning side, our equipment roster includes Rotobrush and Nikro negative-pressure extraction units and Abatement Technologies HEPA filtration, so the air leaving the system during cleaning is cleaner than the air that went in. We don’t use rented shop vacs, and we don’t need to. If you’re in Kent and want to know what equipment will be used on your job, ask us before you book. We’ll name it, and you can look it up yourself.
Common HVAC Cleaning Problems We See in Kent Homes
- Sagged flex-duct runs on East Hill. Homes built between roughly 1980 and 1996 used flexible duct with sparse support strapping. Over 30 years the duct sags between straps, creating low points that trap condensation, dust, and mold. This is the single most common failure we document in Kent, and it’s why a visual-only cleaning that skips the camera inspection misses the real problem.
- Mold colonization in return-air ducts. Kent sits low in the Green River Valley, where marine fog and cool air pool from October through May. Return ducts drawing from crawl spaces pull that damp air into the system, and biological growth follows within a few years if any leak exists. We find this pattern far more often in Kent than in Renton or Federal Way.
- Heavy dust accumulation in mid-century metal ducts near downtown. The ranch homes built near historic downtown Kent in the 1950s and 60s have rigid metal ductwork that holds up structurally but accumulates decades of fine dust, pet dander, and construction debris. These systems often haven’t been opened since the home was built.
- Dirty blower wheels recirculating cleaned air. Some companies clean the ducts and ignore the blower. In Kent’s humid environment, the blower wheel is often coated with a paste of dust and condensed moisture. A week later the homeowner notices dust on furniture again and assumes the cleaning failed. It didn’t. It just didn’t include the blower.

FAQs - HVAC Cleaning in Kent
It comes down to geography and construction era. Kent sits on the floor of the Green River Valley, where marine moisture and fog settle and linger, especially from October through May. Combined with East Hill’s dense concentration of 1980s and 1990s flex-duct systems that are now 30-40 years old with sagging runs and leak-prone connections, the result is ducts that trap moisture and grow mold at a rate upland cities like Renton and Federal Way simply don’t see. Homes on East Hill often need thorough cleaning every 3-4 years, compared to 5-7 years in drier, newer developments. If you’re noticing musty smells or dust returns within weeks of a cleaning, call (806) 606-6902 and we’ll camera-inspect the runs before recommending anything.
No. Fogging without source removal is the most common upsell in this industry, and in Kent’s damp duct environment, it fails predictably within months. A fogging treatment kills surface mold but leaves the organic debris it feeds on. In a climate like ours, the mold comes back, often worse, because the dead spores become food for new growth. The correct sequence is source removal first: physically extract the debris with negative pressure and agitation tools, clean the coil and blower, then apply antimicrobial treatment if warranted. We’ll show you before and after photos of every run so you can see the debris is gone, not just fogged. If a company offers fogging as a substitute for cleaning, treat that as a red flag.
We worked a 1992 split-level in Kent’s Panther Lake area where the return-air flex runs had sagged between loose strapping, trapping condensation and a thick layer of fine dust recirculating every time the blower motor kicked on. Our team camera-inspected the supply and return ducts, used negative pressure with HEPA filtration and agitation tools to source-remove the buildup, then cleaned the evaporator coil and blower. The result was a measurable drop in static pressure and the elimination of a musty smell the homeowners had been masking with plug-ins for a year. That sagging pattern is consistent across 1990s East Hill construction. If your home was built in that era and you’ve never had the duct runs camera-inspected, the odds are high the same issue exists. We include that inspection on every job.
In Kent, the answer is almost always yes, and here’s the simple test: if your ducts have visible dust or mold, the air handler and coil are already contaminated because all the air in your system passes through them. Cleaning the ducts while leaving the coil dirty is like washing your car’s body and leaving mud on the tires. The dirty coil immediately re-contaminates the cleaned ducts. We inspect the coil and blower on every job and include before-and-after photos so you can see exactly what was cleaned. A typical full-system clean in Kent with coil and blower work included runs $380-$690, and we’ll give you the written price before anything comes apart.
Most likely, the rigid metal ductwork in your home has decades of accumulated dust, carpet fibers, and possibly pest debris that no filter change can address. These 1950s and 60s ranch homes near downtown Kent were built with quality metal ducts, but they were never designed to be cleaned, and many haven’t been opened since installation. The dusty smell is that accumulation getting stirred up every time the blower cycles. A proper source-removal cleaning with agitation tools and negative pressure removes the buildup at the source. Afterward, we document the interior of every run with photos so you can see the difference. Call (806) 606-6902 for a written quote on your specific system.
