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.

Air Duct Cleaning Services in Simi Valley
Air Duct Cleaning Services in Simi Valley address the specific contamination this valley traps. Our process starts with a video inspection of your trunk lines and branch ducts, followed by mechanical agitation using Rotobrush rotary tools that physically dislodge debris from duct walls, paired with Nikro negative-air extraction units that pull loosened material out of the system under continuous suction. Abatement Technologies HEPA filtration captures particles as small as 0.3 microns so nothing resettles in your living space during the job. A typical full residential system in Simi Valley runs $450-$650.
Residential Duct Cleaning
Most Simi Valley homes we service are single-story tracts built between 1960 and 1985, with original flex duct or early galvanized sheet metal in the attic. We clean supply branches, return trunks, the air handler cabinet, and the blower motor assembly. The written price covers the whole system, not per-vent add-ons.

Commercial Duct Cleaning
Offices and retail spaces along Los Angeles Avenue and Cochran Street need scheduled cleaning that doesn’t disrupt business hours. We coordinate after-hours or weekend service with the same equipment and the same upfront pricing structure.

HVAC Duct Cleaning in Simi Valley
HVAC Duct Cleaning in Simi Valley must account for how hard this valley’s climate works your system. Summer temperatures regularly exceed 100°F, forcing air conditioners into extended run cycles that pull more dust and particulate through the ductwork. Seasonal Santa Ana winds drive fine matter off the surrounding chaparral hillsides directly into the valley’s air mass. A typical HVAC-specific cleaning in Simi Valley runs $350-$550, with full-system source removal at the higher end.
Supply and Return Duct Cleaning
Supply ducts push conditioned air to your rooms; return ducts pull it back through the filter. Both sides need attention. We frequently find return ducts in Simi Valley homes loaded with the fine gray-tan ash residue that Santa Ana winds and fire events deposit, not ordinary household dust.
Video Inspection and Documentation
Before and after video gives you visual proof of what came out of your system. We record the condition of the trunk line, branch connections, and any flex duct separations. This documentation supports warranty claims and helps you make informed decisions about repairs versus cleaning.
Trusted Brands We Service in Simi Valley
Our technicians arrive with professional-grade equipment, not hardware-store shop vacs. We clean with Rotobrush rotary brush systems for mechanical agitation, Nikro negative-pressure units for source extraction, and Abatement Technologies HEPA filtration to protect your indoor air during the process. For homeowners who want to maintain results between cleanings, we stock and install Aprilaire and Guardsman filtration products designed for the particle loads this valley generates. Parts and filters are available for Simi Valley customers with fast turnaround, so you’re not waiting on warehouse shipping when your system needs attention.
Common Air Duct Cleaning Problems We See in Simi Valley Homes
- Wildfire ash infiltration in hillside-adjacent tracts. Homes north and east of the 118 Freeway, closest to the Santa Susana fire corridors, often show a distinctive fine gray-tan film inside ductwork. Homeowners mistake it for ordinary dust until family members develop persistent respiratory irritation months after a fire event.
- Collapsed or separated flex duct in 140°F+ attics. Simi Valley’s explosive 1960s-1980s development left thousands of homes with original flex duct that has degraded in decades of extreme attic heat. Separated joints pull fiberglass insulation fibers directly into the airstream and deliver them through your vents.
- Chemical fogging sold as “sanitizing” without source removal. Some contractors blow a scented product through the system and call it clean. The dead ash, dust, and biofilm remain. The homeowner gets a temporary smell and a lighter wallet, not a functional improvement.
- Register-only cleaning that ignores the return side and air handler. Cleaning what you can see while leaving the return ducts, blower motor, and evaporator coil untouched means the system re-contaminates itself within weeks. We clean the full path air actually travels.
Pricing for Air Duct Cleaning in Simi Valley, CA
Most Simi Valley homes fall between $350 and $650 for complete duct cleaning, depending on system size, accessibility, and contamination level. A straightforward single-system tract home with standard access typically lands in the $400-$500 range. Homes requiring post-fire source removal with heavy ash loading, or those with multiple HVAC systems and difficult attic access, may reach the upper end.
We do not quote per-vent prices. The written estimate you receive before work begins covers your entire system: all supply branches, return trunks, registers, grilles, air handler cabinet, and blower motor. No door-step revisions. No “we found an extra problem” upsells after we’ve started.
Call (469) 972-3151 for a free written estimate. We’ll ask about your home’s age, system type, and any specific concerns so the price we quote is the price you pay.

FAQs About Air Duct Cleaning in Simi Valley
Smoke and fine ash particles are small enough to infiltrate your return ducts through gaps around the air handler, then deposit throughout the system. We recently worked a 1970s tract home off Tapo Canyon Road, not far from the hillside fire corridor north of the 118, where the homeowner couldn’t figure out why the family kept waking congested months after the Easy Fire. Pulling the air handler and running camera inspection down the main supply and return ducts, we found a fine gray-tan ash film coating the interior walls - not household dust - and the original attic flex duct had separated at a joint and was pulling insulation fibers into the run. After sealing the joint, agitating every branch with rotary tools under negative pressure and HEPA filtration, the system pulled clean and the family’s complaint resolved. Call (469) 972-3151 if your home is in a fire-adjacent neighborhood and you’re experiencing unexplained respiratory symptoms.
No. Fogging a chemical product through the system without mechanical source removal leaves the dead ash, dust, and biofilm exactly where they were. The homeowner pays for a scent, not a clean. True duct cleaning requires physical agitation to dislodge debris and negative-air extraction to remove it. We use Rotobrush tools and Nikro vacuum units for this exact reason. Call (469) 972-3151 for an estimate on actual source removal.
The valley’s inland position produces extreme summer heat that forces HVAC systems into far longer cooling cycles than coastal neighbors, accelerating dust and debris accumulation. Seasonal Santa Ana wind events carry fine particulate matter off the surrounding open hillsides and chaparral directly into the valley’s air mass, increasing the dust load infiltrating home duct systems. These combined factors mean Simi Valley ducts typically need more frequent attention than identical systems in milder climates. Call (469) 972-3151 to discuss a cleaning schedule based on your home’s location and system age.
Yes. Most 1970s Simi Valley tracts have original flex duct or early sheet-metal systems that were never updated. Aging flex duct in attics that bake above 140°F in summer frequently collapses or separates at joints, turning the system into a conduit for attic dust and insulation fibers. We inspect for these failures during our pre-cleaning video assessment and document any repairs needed. The cleaning itself adapts to older materials with controlled brush speed and vacuum pressure to avoid damage. Call (469) 972-3151 for an estimate that includes condition assessment.
We provide before-and-after video documentation of your trunk lines and representative branch ducts. You see what was there and what remains. Our negative-air extraction with Abatement Technologies HEPA filtration captures loosened particles during the cleaning process itself, rather than letting them resettle. The 365-Day Done Right Promise backs this in writing: if the work falls short, we return at no charge. Call (469) 972-3151 to schedule a cleaning with full documentation.
