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.
Fast, Reliable Air Duct Cleaning Across Thousand Oaks
Air duct cleaning in Thousand Oaks typically runs $390-$680 for a full single-system home, and most jobs are completed in four to six hours. The wildcard here isn’t the duct size. It’s what’s inside it. Thousand Oaks sits in a contamination zone unlike almost anywhere else in mainland Ventura County, and a basic clean that skips source removal simply stirs the problem around.
We know the Conejo Valley’s ductwork. The 1965-1985 ranch homes in Wildwood, the two-story tract builds in Lang Ranch, the newer systems in Dos Vientos. We know what Woolsey Fire ash looks like under a camera, and we know what it takes to actually remove it. If you’re in Thousand Oaks and want a written price before anyone touches a register, call (806) 606-6902.
Why CleanRun Air Duct Cleaning Is Thousand Oaks’s Preferred Air Duct Cleaning Company
Since 2013, we’ve built the company around one practice that most of this industry avoids: show the customer the inside of their own ducts before asking for a cent. Every CleanRun visit in Thousand Oaks includes a documented photo record of every duct run, before and after. Not a verbal summary. Photographs. On a post-Woolsey job in Lang Ranch, our crew pulled a register in a 1978 tract home and found the interior of the return duct coated in a fine gray ash layer from the negative pressure of the HVAC system during the fire. The homeowner had no idea. The camera showed it in thirty seconds.
That’s how we work. Our Air Duct Cleaning team operates under the H.A.V.E.N. Standard, with background-checked, uniformed technicians who arrive with their names on the work order and their license number on paper, not tucked in a footer. Every job starts with a written price under Haven Standard Clause 1. No call-for-a-quote games. No per-vent pricing. One number, in writing, before any panel comes off.
Tomas Reyes has led CleanRun since the first job in 2013. The 365-Day Done Right Promise is his written rule, not a training slogan: if the work is not right, we make it right. What we do and what we won’t do is all in writing, every time, for every Thousand Oaks homeowner.
Our Air Duct Cleaning Services in Thousand Oaks

Thousand Oaks homes need more than a surface-level filter change. Here’s what we actually do inside the ductwork, and why each service matters in this city specifically.
Residential Duct Cleaning
Most Thousand Oaks homes fall into two camps: original 1960s-1980s duct systems in ranch-style and two-story tract homes, or newer flex-duct setups in developments like Dos Vientos and Westlake-adjacent pockets. The older systems are the ones that show real problems: collapsed sections, delaminated fiberglass duct board, and decades of the city’s oak pollen compacted onto interior surfaces. We clean the full run, supply and return, then photograph the result.

Commercial Duct Cleaning
Retail and office spaces along Thousand Oaks Boulevard and Hillcrest Drive face the same contamination profile as homes, plus higher foot traffic and longer HVAC runtime. We schedule commercial jobs around business hours and document every register and plenum. Property managers in Thousand Oaks get the same written price before work begins that a homeowner gets.

Supply Duct Cleaning
The supply side is where you breathe from. In Thousand Oaks, supply ducts are often the cleanest-looking surfaces in the system, because air is forced out under pressure. But the interior walls hold fine particulate that a visual check of the register won’t reveal. We use negative-pressure extraction and HEPA-filtered agitation tools to pull that material out at the source.

Return Duct Cleaning
Return ducts are the collector’s item in Thousand Oaks. Because returns pull air inward, they act like a vacuum bag for everything in the home’s air: oak pollen, chaparral dust, Woolsey Fire ash, pet dander, and fine silt driven by Santa Ana winds. In Wildwood and Lang Ranch homes built after 1970, return ducts frequently show 2-to-4-inch accumulations at the first elbow. That’s the first place a camera goes.

We’ll name the machine and explain what it does.
Common Air Duct Cleaning Problems We See in Thousand Oaks Homes

- Post-Woolsey ash in return registers. Homes in Wildwood and Dos Vientos that had no visible exterior fire damage still show a fine gray coating inside return ducts. The negative pressure of running HVAC during evacuation orders pulled smoke and combustion particulates into the ductwork for days. Changing the filter does nothing once that ash has settled inside the run.
- Oak pollen film feeding mold. Thousand Oaks has one of the densest live oak and valley oak canopies in Ventura County. When the Point Mugu marine layer pushes coastal moisture into unconditioned attics, that sticky pollen layer becomes a growth surface. Technicians unfamiliar with the Conejo Valley often skip interior agitation and leave the film in place.
- Delaminated fiberglass duct board from 1960s-1980s builds. The original duct board in thousands of Thousand Oaks ranch homes has been degrading for 40 to 60 years. A negative-pressure-only clean can actually loosen fibers and push them toward the supply registers. Without a camera inspection after the clean, you’d never know it happened.
- Santa Ana dust loading in attics and ducts. The Conejo Valley funnels and accelerates Santa Ana wind events. Fine chaparral dust and regional smoke load into home envelopes every fall and winter, and the HVAC system distributes it room to room. Filters trap some; the rest accumulates in the runs.

FAQs - Air Duct Cleaning in Thousand Oaks

The only way to know is to look inside the ducts with a camera. We pull a register and inspect the return run, which is where ash settles first. In post-Woolsey remediation work across Wildwood, Lang Ranch, and Dos Vientos, we routinely find fine gray ash inside ducts of homes that looked untouched from the street. If you ran your HVAC during the fire or in the weeks after, there’s a strong chance combustion particulates are still in the system. Call (806) 606-6902 to schedule a camera inspection before paying anyone to clean.
Yes. The marine layer pushes humid air into unconditioned attics, and Thousand Oaks’s heavy oak-pollen load gives that moisture something to hold onto. Pollen film inside ducts becomes a microbial growth surface when humidity stays elevated. We’ve seen it in aging fiberglass duct board throughout the city. A camera inspection confirms it, and source removal addresses it.
Source removal physically extracts debris from the duct interior using negative pressure and HEPA-filtered agitation. Fogging sprays a chemical mist into the system, but it doesn’t remove the ash, pollen, or dust that’s still there. In Thousand Oaks, where Woolsey ash and oak pollen are the actual problem, fogging alone is a cosmetic upsell. We don’t fog as a substitute for cleaning. If sanitizing is applied, it comes after the debris is gone and its purpose is microbial treatment, not contamination removal. Read any quote carefully and ask what’s being physically removed versus sprayed.
Yes, usually. Homes built between the mid-1960s and mid-1980s in Thousand Oaks often have original fiberglass duct board or early-generation flex duct. That material degrades over time, delaminates internally, and holds debris more stubbornly than the smooth metal or newer flex used in modern construction. If your home still has its original duct system, an inspection is worth it regardless of how recently you changed the filter. Degradation isn’t visible from the register.
Ask for photographs of the inside of every duct run, not just the registers. A before-and-after photo record is the only way to verify that debris was actually removed from interior surfaces, and it’s a standard deliverable on every CleanRun job. Also ask for a camera pass at the plenum and any elbows, because that’s where debris hides in older systems. If a company won’t show you the inside of your own ducts before and after, the work wasn’t documented. Get the photo record in writing before you pay.
