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.

Ductwork Cleaning in Simi Valley
Ductwork cleaning in Simi Valley means removing the accumulated dust, pet dander, and construction debris from both supply and return runs, the trunk lines, and the air handler itself. In Simi Valley’s older homes along Cochran Street and Erringer Road, we regularly find return runs that have never been opened in 40 or 50 years. A full ductwork cleaning for a typical Simi Valley home runs $350 – $600 depending on square footage and the number of systems. What makes Simi Valley different from coastal cities is the fine, wind-driven grit from Santa Ana events that settles into every horizontal surface of the duct system, especially the long sloped return trunks common in mid-century construction.
Return Duct Cleaning and Why It Matters Here
Return ducts pull air back toward the furnace or air handler. In Simi Valley, many 1960s – 1980s homes have return runs that slope gently and are hard to access, which means dust and debris settle and pack in over decades. A camera inspection before cleaning is the only way to see what’s actually in there. We clean return ducts with the same negative-pressure extraction we use on supplies, and we photograph the result.
Supply Duct Cleaning for Consistent Airflow
Supply ducts carry conditioned air to each room. When they’re lined with dust, the system works harder and some rooms run warmer than others. Simi Valley summers push HVAC systems hard, and a clogged supply run near the air handler can make a hot August afternoon worse. We clean supply runs thoroughly with rotary brush agitation paired with HEPA filtration, so loosened debris goes straight into the vacuum rather than back into your home.
Air Duct Inspection in Simi Valley
An air duct inspection in Simi Valley is a camera walk-through of your supply and return ductwork, and it costs $99 – $199 when booked as a standalone service. For Simi Valley homes with dust settling fast after cleaning, unexplained allergy symptoms, or rooms that never hold temperature, a video inspection finds what the naked eye can’t. Simi Valley’s dry, windy weather patterns mean fine particulate makes its way into ducts even when windows stay shut, so visual inspection of registers won’t tell you the whole story. The camera does.
What We Check During an Inspection
We run a flexible camera scope through the main supply and return trunks, looking for debris buildup, disconnected joints, pest activity, and moisture damage. In Simi Valley’s older neighborhoods, disconnected duct joints are common and can pull attic insulation directly into the airflow. We document findings with photos and walk you through what actually needs cleaning versus what’s best left alone.
When You Don’t Need a Cleaning
Not every dusty home needs duct cleaning. If your registers show light dust that wipes clean easily and your filter is doing its job, you may just need a filter upgrade. We’ll tell you that plainly. Our inspection service exists to give you an honest answer, and if cleaning isn’t necessary, we say so without charging you for work you don’t need.
Trusted Brands We Service in Simi Valley
Our crews work on every major duct and filtration brand found in Simi Valley homes, and we carry local stock for common replacement parts. That includes Aprilaire filtration units, Guardsman registers and components, and system types that use Rotobrush-compatible access points for cleaning. For Simi Valley homeowners with Honeywell media cabinets or Aprilaire whole-home filtration, we can evaluate filter condition during the same visit. Because we operate with local crews in Simi Valley, we’re not waiting on a remote parts warehouse for standard items, which keeps turnaround tight and avoids a second visit.
Common Air Duct Cleaning Problems We See in Simi Valley Homes
- Wind-driven fine dust from Santa Ana events. Simi Valley sits in a valley ringed by hills, and when the winds pick up, fine grit pushes through window seals, door gaps, and even closed registers. This ultra-fine dust settles deep inside long horizontal runs and resists standard vacuum-only cleaning.
- Sloped, hard-to-reach return trunks in 1960s – 1980s builds. Many homes near the center of Simi Valley, around Fitzgerald Road and Sycamore Drive, still have original return runs that slope gently and are difficult to access. Debris packs in over decades and requires camera inspection plus rotary agitation to fully clear.
- Dust settling within a day of cleaning. When past cleanings skipped the return side or the air handler cavity, debris simply recycled back through the supply runs within 24 hours. We see this pattern frequently in older Simi Valley ranch homes, and it’s the exact reason we photograph both supply and return runs before and after.
- Per-vent pricing that skipped the long runs. Homeowners in Simi Valley occasionally show us invoices from companies that charged per vent and then skipped the longest, hardest duct runs to save time. The result is a partial cleaning that doesn’t last. We price one flat rate per system, so there’s no incentive to cut corners on the hard-to-reach sections.
Pricing for Air Duct Cleaning in Simi Valley, CA
A full air duct cleaning for a typical single-family home in Simi Valley runs $350 – $600.

Video inspection as a standalone service runs $99 – $199. The key difference from per-vent pricing is that we quote one flat price for the entire system before work begins.

Call (737) 727-2314 for an exact quote on your Simi Valley home, and we’ll walk you through what’s included.

FAQs About Air Duct Cleaning in Simi Valley
Most Simi Valley homes need professional air duct cleaning every 3 – 5 years, though homes with pets, recent remodeling, or heavy Santa Ana dust exposure may need it more often. The real trigger isn’t a calendar, it’s what you see: dust settling on furniture within a day or two of cleaning, visible debris around register openings, or rooms that won’t hold temperature. If you’re unsure, a $99 – $199 video inspection tells you definitively. Call (737) 727-2314 and we’ll help you decide.
We charge one flat price per system, agreed in writing before any duct is touched. That means no per-vent pricing and no incentive to skip the long, hard-to-reach return runs that older Simi Valley homes are full of. A typical full system runs $350 – $600. The quote you approve is the price you pay.
Our process starts with a camera inspection of the supply and return trunks, so we know what’s actually inside. Then we use rotary brush agitation under negative pressure with HEPA filtration to loosen and extract debris without releasing it into your home. We photograph every step, and you receive before-and-after photos of your own ducts. One flat price per system, written before we start. Call (737) 727-2314 for specifics on your Simi Valley home.
Scheduling depends on current availability, and we don’t promise same-day service because rushing a duct cleaning in a home with sloped, hard-to-access return runs means missing debris. What we do guarantee is a live trackable arrival window, a written price before work starts, and before-and-after photos when the job is done. Call (737) 727-2314 and a live person will give you real scheduling options for Simi Valley.
If dust reappears within 48 hours after cleaning surfaces, or if your filter clogs unusually fast, the issue is likely inside the ducts. A filter change takes five minutes and won’t address debris packed into a sloped return trunk. A video inspection answers this conclusively, and it runs $99 – $199. If inspection shows your ducts are fine, we’ll tell you and you’ll only pay for the inspection. Call (737) 727-2314 to schedule one in Simi Valley.
