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 Simi Valley
Air duct cleaning in Simi Valley typically costs $395-$690 for a full single-system home, and the work takes 3-5 hours when done right. That price should include source removal, not just a vacuum pass, and you should receive photo documentation of every duct run before and after. CleanRun Air Duct Cleaning has worked Simi Valley homes since our founding in 2013, and we’re familiar with what this valley’s specific conditions do to ductwork. Call (806) 606-6902 for a written price before any work starts.
Why CleanRun Air Duct Cleaning Is Simi Valley’s Preferred Air Duct Cleaning Company
Simi Valley homeowners call us because we show them what we found. Every job ends with a Documented Photo Record of the inside of every duct run, before and after, delivered as a standard part of the work record. That matters here more than most places. The homes off Madera Road, along the 118 corridor, and up toward the hills above the Reagan Library carry a specific dust signature we don’t see in coastal cities: fine grayish-black ash layered over decades of ordinary household dust. It’s the residue of the 2003, 2018, and 2019 fire seasons, and it tells us exactly what your system has been circulating.
Our Air Duct Cleaning crews serve Simi Valley with background-checked, uniformed technicians operating under the Haven Standard. We publish our license number on the page. We don’t bury it in fine print. And we don’t work from a cheap coupon that gets inflated once a tech is standing in your hallway. Haven Standard Clause 1: a written price before any panel comes off. That’s the entire business model.
Reviews from Simi Valley customers consistently mention two things: the technician showed up on time and identified by name, and the before-and-after photos made it obvious the work actually happened. We’ve served 52,000+ homes since 2013, every one with a written price first and a documented photo record when the crew left. In Simi Valley specifically, that record often shows the moment we pulled a collapsed fiberglass duct joint back into alignment or cleared a return packed with Santa Ana driven particulate. That’s the kind of evidence no fogging upsell can fake.
Our Air Duct Cleaning Services in Simi Valley
Residential Duct Cleaning
Most Simi Valley homes we clean were built between the late 1960s and the 1980s. The tract-home boom that filled this valley left behind single-story ranches with large attic duct runs, often original fiberglass duct board or early flex duct. A residential clean in these homes means working through supply and return sides, sealing collapsed joints where needed, and removing the accumulated particulate that’s been cycling through since the last major fire event. We quote a flat whole-system price, not a per-vent figure.
Commercial Duct Cleaning
Simi Valley’s commercial spaces along Cochran Street, Tapo Canyon Road, and Erringer Road face the same post-wildfire particulate load as residential systems, compounded by longer runtimes and higher occupancy. We clean office, retail, and medical spaces with the same documented before-and-after record we provide in homes. Commercial pricing is set by square footage and system configuration, written and delivered before work begins.
Supply Duct Cleaning
Supply ducts push conditioned air into your rooms. In Simi Valley, those supplies run through attic spaces that regularly exceed 130°F from June through September. That heat accelerates duct lining deterioration and recirculates fine particulate every time the system cycles. Our supply duct cleaning includes camera inspection of each run and removal of the ash-and-dust load that’s settled at elbows and joints. We photograph every run before and after.
Return Duct Cleaning
The return side is where Simi Valley homes accumulate some of their heaviest debris. Santa Ana winds funnel dust, pollen, and fire ash directly toward return-air intakes, and over time that material builds up in return ducts and the plenum. Skipping return cleaning means the system re-pressurizes with the exact particulate you just paid to remove from the supply side. We include both supply and return cleaning in every full-system job. A video inspection tells us what’s actually in there before we quote the work.
Full System Cleaning
A full system clean in Simi Valley means the supply runs, return runs, plenum, blower compartment, and registers. It’s the only approach that addresses what this valley’s fire history leaves inside ductwork. We use negative-pressure extraction with HEPA filtration, powered agitation, and source removal rather than surface-level vacuuming. The equipment is professional-grade: Rotobrush, Nikro, and Abatement Technologies, so you can verify what’s being used before agreeing to a price.
Video Inspection
Before we quote a full clean, we run a camera through the ductwork. In Simi Valley this inspection frequently shows things the homeowner had no way of knowing about: a separated joint in an attic run, a return packed with years of Santa Ana grit, or the gray-black film that post-fire ash leaves over old dust. Video inspection is the diagnostic step that separates source removal from guesswork. It’s included as part of the documented record.

BeforeAfterTrusted Brands We Service in Simi Valley
Simi Valley’s housing stock spans five decades of HVAC equipment, and we service the brands most common in this valley. We work on systems from Honeywell and Aprilaire among others, and we stock the duct repair materials, sealing compounds, and filtration components needed for the 40 to 50-year-old ductwork common in this area. We don’t push replacement when a repair and clean will do the job, and we quote every repair in writing before any work starts. If your system uses a Guardsman filter housing or other less-common components, we’ll tell you what we found and what your options are, in plain language, with a written scope.
Common Air Duct Cleaning Problems We See in Simi Valley Homes
- Post-wildfire ash layering. Simi Valley sits in an inland valley ringed by fire-prone hills. The Easy Fire in 2019 scorched hillsides directly above the city near the Reagan Library, and the Santa Ana winds that funnel through the valley’s east-west corridor pushed fine combustion debris deep into return-air intakes. Years later, that grayish-black film still coats duct interiors and cycles through systems every heating and cooling season.
- Collapsed fiberglass duct board. The 1970s tract homes in neighborhoods along the 118 corridor frequently carry original fiberglass duct board. After 40 to 50 years in attic heat that passes 130°F, seams separate, joints collapse, and the ducts start pulling attic air into the system. A basic vacuum clean won’t fix that. The opening has to be sealed or reconnected, or the system re-contaminates within months.
- Santa Ana dust accumulation in returns. The same topography that traps heat also channels seasonal wind events through the valley. Dust, pollen, and wildfire ash move directly toward return-air intakes. We regularly find returns packed to the point of restricted airflow, which forces the blower to work harder and pulls debris through the entire system.
- Musty or acrid indoor odor with no visible source. Many Simi Valley homeowners describe a persistent smell they can’t locate. It’s not standing water. It’s not the carpets. It’s post-fire particulate embedded in the duct lining. That smell often sharpens when the furnace or AC first kicks on, and it doesn’t go away with filter changes. Source removal is the fix.
Pricing for Air Duct Cleaning in Simi Valley, CA
We don’t price by the vent, and we don’t run a $79 coupon that turns into a $1,200 invoice. Simi Valley full-system cleans with our equipment and documentation typically run $395-$690 for a standard single-family home, depending on system size and how much repair work the ducts need. Homes with multiple HVAC systems, severely collapsed duct board, or extensive post-fire ash accumulation run higher, and we tell you that in writing before any work starts. If a competitor gives you a written estimate, bring it in. We’ll put our own number next to it, in writing, at no charge. That’s our Free Second Opinion policy, and it applies throughout Simi Valley.
Every job is backed by the 365-Day Done Right Promise. If the work is not right, we make it right. That’s a written guarantee, not a manager’s discretion call. Call (806) 606-6902 for a written price.

FAQs - Air Duct Cleaning in Simi Valley
Because the smell is coming from inside your ductwork, not from your filters or floors. Simi Valley’s post-fire dust signature is a layer of grayish-black ash that settled inside duct runs after the 2003, 2018, and 2019 fire events. That ash coats the duct interior and releases an acrid smell each time the system cycles, especially during summer’s long AC runtimes. Replacing filters doesn’t touch it. Carpet cleaning can’t reach it. The fix is source removal with proper negative-pressure extraction and HEPA filtration, followed by documenting what was pulled out. Call (806) 606-6902 and we’ll show you what’s actually in your ducts before quoting the work.
Yes, typically every 3 to 5 years in Simi Valley versus every 5 to 7 years in coastal Ventura. The difference is wildfire ash and Santa Ana particulate. Coastal cities deal mainly with household dust and some mold. Simi Valley’s enclosed valley geography traps heat and fire debris, and seasonal wind events push fine particulate directly into return-air intakes. That combined load accumulates faster and coats duct interiors more aggressively. A home off the 118 corridor that hasn’t been cleaned since 2019 is almost certainly carrying visible ash layers by now. We’ll confirm it with a camera inspection.
No. A fogging treatment mists a chemical into the ductwork but does not remove the debris that’s physically sitting in the runs. In Simi Valley, that debris is wildfire ash and Santa Ana dust layered over years of household particulate. A fog won’t pull that out. It just leaves a chemical scent over the top of it, and the underlying material keeps circulating every time your system runs. What’s actually worth paying for is source removal: physically extracting the debris with HEPA-filtered negative pressure and powered agitation, then documenting every run with before-and-after photos. If a company leads with fogging instead of removal, ask what they’re not removing.
Yes, original fiberglass duct board from the 1970s can be cleaned safely if the material is still structurally intact. The bigger issue we see in Simi Valley’s 1970s tract homes is collapse: seams that have separated, joints that have come loose, sections where the duct board has degraded in attic heat past 130°F. A proper clean includes inspecting those joints and sealing or repairing what’s failed. If a section is too far gone, we’ll show you the photo and tell you in writing what replacement would cost. You don’t have to guess, and we don’t clean around a problem we can see.
Because Simi Valley’s geography concentrates particulate in ways the San Fernando Valley’s wider basin doesn’t. Simi Valley is an enclosed east-west valley ringed by fire-prone hills. Heat gets trapped, and Santa Ana wind events funnel dust, pollen, and wildfire ash through the corridor and directly into return-air intakes. Our crew worked a 1970s ranch off Madera Road where the original fiberglass duct board had collapsed at a joint in the blazing attic. We pulled the blower motor, ran a camera inspection through the supply and return ducts, and found a thick gray-black film over decades of dust-post-Easy Fire ash that had cycled through the air handler every Santa Ana season. After source removal with HEPA-filtered negative pressure and sealing the collapsed section, that smell finally cleared. That level of accumulation is common here and less common 30 miles south in the San Fernando Valley. If your ducts are filling faster than they used to, call (806) 606-6902 for a video inspection and a written quote.
