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 Auburn
HVAC cleaning in Auburn, WA typically runs $385-$690 for a full system cleaning on a standard 2,000-2,600 sq ft home, and takes between 3 and 5 hours. That includes the air handler, evaporator coil, blower assembly, supply and return duct runs, and a documented photo record of every register before and after. If your home sits on the Green River Valley floor, where fog lingers and crawl spaces stay damp for months, the evaporator coil is almost certainly carrying a biofilm layer that a standard filter change won’t touch. Call (806) 606-6902 and we’ll send a written price before any panel comes off.
We work in Auburn every week. Our crews know West Hill’s 1970s split-levels, the ranch rows off Lea Hill Road, and the newer slab-on-grade builds south of Highway 18. We treat the valley-floor humidity as a working condition, not an excuse to upsell you. CleanRun Air Duct Cleaning is part of the HVAC Cleaning team serving Auburn with written pricing, source-removal equipment, and a photo record on every visit.

Why CleanRun Air Duct Cleaning Is Auburn’s Preferred HVAC Cleaning Company
Auburn homeowners call us because they want to see the inside of their ductwork before they pay for a cleaning. We have held that position since CleanRun was established in 2013, and we have not wavered on it. Tomas Reyes, who leads our operations, is the one who signs off on the 365-Day Done Right Promise that goes in writing on every job. That promise means what it says: if the work is not right, we make it right. Not after a manager review, not after a negotiation. It is on the page.
Our crews arrive in uniform, background-checked, and identified by name before the door opens. They operate under the H.A.V.E.N. Standard, and Clause 1 is the one our Auburn customers mention most: written price before any work starts. There is no “let’s start and see how it goes.” There is a number on a page, agreed to up front. If you already have a written estimate from another company, bring it. We will put our own number next to it in writing under our Free Second Opinion policy.
Auburn-specific knowledge matters here. A technician who only works hilltop homes in Kent or Renton may not know that vented crawl spaces on the valley floor hold moisture into July. We do. It changes where we look first: at the flex duct joints under the house, where adhesive fails and rodents get in. That is not general HVAC knowledge. It is Auburn knowledge, earned by opening hundreds of crawl-space hatches in this city.
Our HVAC Cleaning Services in Auburn
Air Handler Cleaning
The air handler is the box that moves air through your system, and in Auburn’s valley-floor homes it is often pulling air from a damp crawl space or a garage with high humidity. We remove the blower housing, clean the interior surfaces with HEPA-filtered negative-pressure extraction, and photograph the result. In older West Hill and Lea Hill homes, we routinely find a gray paste of dust and moisture on the interior walls of the handler, which shortens blower motor life and pushes musty air through every register. Air handler cleaning in Auburn typically runs $150-$260 as part of a full system cleaning.
Evaporator Coil Cleaning
The evaporator coil sits inside the air handler and is the coldest surface in the system. In Auburn’s chronically damp valley air, condensation forms on the coil and traps airborne dust, smoke particulate, and mold spores faster than it does in hilltop neighborhoods like Federal Way or Kent’s East Hill. We see coils that are 60-70 percent occluded with a wet, fibrous mat after just three or four years in valley-floor homes. Evaporator coil cleaning in Auburn usually runs $180-$320, and we apply a coil treatment to delay re-fouling.
Blower Cleaning
The blower wheel is the fan that pushes conditioned air through your ductwork. When the wheel blades load up with debris, airflow drops and your furnace runs longer to hit the thermostat setpoint. In Auburn homes that burn wood or sit near unpaved roads on the city’s rural fringe, blower cleaning is often the single highest-impact service we perform. A blower cleaning in Auburn typically runs $120-$220, and we photograph the wheel before and after so you can see the difference.
Condenser Cleaning
The outdoor condenser coil sheds heat from the system, and it is the one component exposed to Auburn’s late-summer smoke events. Fine ash from Eastern Washington wildfires settles into the coil fins and reduces heat rejection, forcing the compressor to work harder. We clean condenser coils with proper coil cleaner and low-pressure water, never a pressure washer that can fold the fins flat. Condenser cleaning in Auburn runs $110-$190.

BeforeAfterTrusted Brands We Service in Auburn
We service and clean equipment from every major manufacturer, but Auburn homeowners often ask what gear we use on their systems. Our crews run Rotobrush and Nikro negative-pressure extraction equipment, paired with Abatement Technologies HEPA filtration on source-removal jobs. These are not off-the-shelf shop vacs. They are professional-grade machines designed to pull debris out of duct runs at the source, not push it around. If you want to verify what we are using before you agree to a price, the brand names are on the written quote.
Common HVAC Cleaning Problems We See in Auburn Homes
- Flex-duct joint failure in vented crawl spaces. Valley-floor moisture softens duct tape adhesive and insulation wrap, causing joints to sag or separate entirely. A separated joint leaks conditioned air into the crawl space and pulls crawl-space air into your home. We find this in 1965-1990 ranch and split-level homes throughout West Hill and Lea Hill more than any other single issue.
- Rodent nesting inside duct runs. Older valley-floor homes with original duct systems frequently have at least one run a mouse or rat has turned into a nest. The signs are a distinct ammonia odor from certain registers and fine nesting debris on the supply side. Register vacuuming does not remove this. Source removal with negative pressure and HEPA filtration does.
- Late-summer wildfire smoke loading. When smoke settles into the Green River Valley, it does not just sit outside. Your blower pulls it through the return, and fine particulate embeds in the evaporator coil and blower wheel. Auburn homeowners with systems that ran during smoke events often notice a stale, ashy smell at the registers for weeks after. A post-smoke coil and blower cleaning addresses it.
- Biofilm on evaporator coils from chronic humidity. Auburn’s valley floor stays damp after surrounding hilltop cities have dried out. That persistent moisture turns the evaporator coil into a condensation plate where mold and biofilm establish quickly. A coil that is only 40 percent blocked still measurably reduces system efficiency and contributes to that musty smell when the AC first kicks on.
Pricing for HVAC Cleaning in Auburn, WA
Here are the ranges we quote on HVAC cleaning in Auburn, written before any work starts:
| Service | Auburn Price Range |
|---|---|
| Full HVAC cleaning (air handler, coil, blower, duct runs, registers) | $385-$690 |
| Air handler cleaning (standalone) | $150-$260 |
| Evaporator coil cleaning with treatment | $180-$320 |
| Blower cleaning (standalone) | $120-$220 |
| Condenser cleaning (outdoor unit) | $110-$190 |
What moves the price is the size of the home, the number of duct runs, whether the crawl space is accessible, and the condition of the flex-duct connections. A 3,000 sq ft Lakeland Hills home with 14 runs costs more than a 1,200 sq ft ranch off Auburn Way South with 6 runs. We do not charge per vent. We quote one flat price per system before work starts, and that price is the price. Call (806) 606-6902 and we’ll send a written quote without sending anyone to your house first if the home’s details are straightforward.

FAQs - HVAC Cleaning in Auburn
In Auburn’s valley-floor neighborhoods, we recommend a full HVAC cleaning every 2-3 years, compared to every 3-5 years for hilltop homes in Federal Way or Kent’s East Hill. The valley traps fog and marine air long after surrounding hills clear, so crawl spaces and low-lying duct runs stay damp for more of the year. That moisture accelerates coil fouling, flex-duct adhesive breakdown, and biofilm growth. It is not a marketing schedule; it is what the camera shows us when we inspect valley-floor systems. Call (806) 606-6902 and we can tell you what your specific home needs after a visual inspection.
Yes, if your system ran during a smoke event and you smell ash at the registers weeks later, the blower and evaporator coil are carrying a fine particulate load that a filter change will not remove. The Green River Valley acts as a settling basin for smoke, so Auburn holds that particulate longer than surrounding elevated areas. We inspect and clean the blower wheel, coil, and accessible duct runs after significant smoke events. The photo record shows you what was in there before we started.
A 1970s split-level on West Hill almost always has flex duct routed through a vented crawl space, which means moisture, pest intrusion, and sagging joints are the dominant issues. A newer slab-on-grade home in south Auburn typically has shorter, tighter duct runs with less pest exposure, but higher sensitivity to construction debris left in the system and smoke particulate on the coil. We clean both, but we open the crawl-space hatch on the West Hill home first. That is where the problem usually lives.
In most cases, rodent nesting can be removed with source-removal equipment and the duct can be sanitized and re-secured. Replacement is only necessary when the flex duct is chewed through, crushed, or the nesting has contaminated the insulation wrap beyond cleaning. We show you the camera footage before we quote anything. If a run needs replacement, we quote that separately in writing. If it can be cleaned, we clean it and document it.
Because the evaporator coil is the coldest surface in your system, and Auburn’s valley floor keeps indoor humidity elevated for more of the year than surrounding hilltop neighborhoods. More moisture on the coil means more airborne particulate sticks to it. Add late-summer smoke settling into the valley, and you get a coil that fouls in two to three years instead of five. We include coil cleaning and a coil treatment in every full HVAC cleaning we perform in Auburn. Call (806) 606-6902 for a written price.
What We Found on Lea Hill Road
On a ranch-style home off Lea Hill Road last spring, we camera-inspected a flex-duct run in a vented crawl space and found a collapsed joint where valley-floor moisture had softened the duct tape. Mice had nested inside the separated run, and the air handler was pulling crawl-space air into the master bedroom. We performed source removal with negative pressure and HEPA filtration, cleaned the air handler and evaporator coil, then re-secured and reinsulated the run before photographing the finished work. That is not a worst-case story. It is a Tuesday in Auburn.
If your home was built between 1965 and 1990, sits on the valley floor, and has never had a camera inspection of its ductwork, call (806) 606-6902. We will send a written price before any work starts, and you will have a photo record of every run when we leave. That is the CleanRun standard in Auburn, and it has been since 2013.
