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 Agoura Hills
Most homes in Agoura Hills need a full air duct cleaning every three to five years, with a typical residential system running between $450 and $850 depending on size, access, and how much debris has built up in the ductwork. We’re Kestrel Air Duct Cleaning, and we dispatch crews to Agoura Hills from our Los Angeles scheduling office, with most jobs booked within a week and completed in a single morning or afternoon. You can reach us at (469) 972-3151 for a free written estimate, no obligation.
We’ve worked the canyon corridors of Agoura Hills long enough to know this isn’t generic suburban ductwork. The late-1970s through early-1990s buildout that defines most of the city’s housing stock, combined with repeated wildfire smoke exposure and Santa Ana wind events, creates a contamination profile you won’t find in flatland cities. Our Air Duct Cleaning team treats that difference seriously.
Why Kestrel Air Duct Cleaning Is Agoura Hills’s Preferred Air Duct Cleaning Company
Our reputation in Agoura Hills was built after the Woolsey Fire, when hundreds of local homeowners needed honest answers about whether their ducts were safe to run. We didn’t upsell fogging treatments or push unnecessary work. We showed up in the window we promised, put the price in writing before touching a vent, and ran cameras through the system so owners could see exactly what was inside. That approach earned us a strong local following in neighborhoods from Old Agoura to Fountainwood.
Calls from Agoura Hills reach a live person, not a phone tree, any time of day. Our technicians are background-checked, uniformed, and trained on the specific failure modes of 30-to-45-year-old flex ductwork, the kind that runs through most Agoura Hills attics and crawl spaces. We know the difference between a ranch off Kanan Dume Road and a Mediterranean tract near the 101, and we adjust our access approach accordingly.
Every job carries the Kingswell Guarantee: written price before work begins, defined arrival window, clean job site, and a written 365-Day Done Right Promise with a free return visit if anything fails within that period. Dale Whitmore, who leads Kestrel Air Duct Cleaning, insists on this standard for every Agoura Hills home we enter.
Ductwork Cleaning in Agoura Hills
Ductwork Cleaning in Agoura Hills means source removal of the embedded ash, char particulate, and chaparral dust that accumulates in flex duct systems, not a surface wipe or a scented fogging treatment. We use Rotobrush rotary brush agitation, which is a motorized brush head that physically scrubs debris loose from the duct interior, followed by Nikro negative-air extraction, which pulls that loosened material out under controlled suction so it doesn’t re-enter your living space. Abatement Technologies HEPA filtration captures particles down to 0.3 microns during the process. A typical residential Ductwork Cleaning in Agoura Hills runs $450-$850 for a full system, with larger homes or systems with significant smoke damage sometimes reaching $1,100-$1,400.
Supply and Return Line Cleaning
Supply ducts push conditioned air into your rooms; return ducts pull it back to the air handler. In Agoura Hills homes, we often find the return side more heavily loaded with ash and dust because it’s the path of least resistance for outdoor particulate drawn through intake grilles during Santa Ana events. We clean both sides as a matched system, never one without the other.
Main Trunk and Branch Line Restoration
The main trunk is the large central duct that feeds smaller branches to individual rooms. In older Agoura Hills systems, sagging flex duct at branch takeoffs creates debris traps where ash and dust compact over years. Our techs cut service ports at the plenum to access these areas directly, remove the buildup, and reseal any separated joints we find.
Air Duct Inspection in Agoura Hills
Air Duct Inspection in Agoura Hills is the right starting point when you suspect contamination but aren’t sure whether full cleaning is warranted, or when you’re buying a home and want documentation of duct condition before closing. We run a video camera through the full supply and return network, recording footage you can review in real time. The inspection documents ash layers, joint separations, rodent activity, or moisture staining that might not show at the register. An Air Duct Inspection in Agoura Hills typically costs $150-$275, and if you proceed with cleaning within 30 days, we apply that fee toward the work.
Post-Fire Damage Assessment
Homes that survived the Woolsey Fire with intact roofs and walls often still carry significant duct contamination. Our inspection specifically documents smoke residue patterns, which differ from ordinary dust loading and require different cleaning intensity. We flag whether the contamination is surface-deposited or deeply embedded, so you know what you’re dealing with before committing to any work.
Pre-Purchase Documentation
Agoura Hills’s 1970s-1990s housing stock means many transactions involve original ductwork. Our inspection gives buyers leverage in negotiation and gives sellers a defensible condition report. We note duct age, material type, visible damage, and estimated remaining service life, all in writing.
Trusted Brands We Service in Agoura Hills
Kestrel technicians are trained on equipment from Rotobrush, Nikro, and Abatement Technologies, the three professional-grade systems we deploy on every Agoura Hills job. Rotobrush handles the mechanical agitation that dislodges debris from flex duct walls without tearing the liner. Nikro provides the negative-pressure containment that prevents recontamination of your home during cleaning. Abatement Technologies HEPA filtration ensures what we pull out of your ducts stays out of your air. For homeowners who want to maintain results between cleanings, we also stock Honeywell, Aprilaire, and Guardsman filtration and indoor-air-quality products with fast local turnaround.
Common Air Duct Cleaning Problems We See in Agoura Hills Homes
- Woolsey Fire ash embedded in original flex duct. The 2018 fire enveloped much of Agoura Hills in smoke for days, and the fine particulate settled deep into porous flex duct interiors. Many owners never scheduled post-fire cleaning. We still find gray-black ash layers in homes off Kanan Dume Road and throughout Old Agoura.
- Santa Ana wind redeposition through outdoor intakes. Every fall and winter, canyon corridors funnel chaparral dust and ash directly into HVAC air intakes. This isn’t a one-time problem. Homes near Ladyface and Fountainwood see recurring buildup that flatland cities simply don’t experience.
- Sagging and separated joints in 30-45-year-old ductwork. The suburban buildout era used flex duct that degrades with age. Sagging creates low spots where debris accumulates; separated joints leak conditioned air and draw attic or crawl-space contamination into the system.
- Shop-vac “cleaning” that stirs debris without removing it. We’ve been called after other contractors ran a consumer vacuum at the registers and called it done. Without negative-air extraction and HEPA containment, this just redistributes fine ash into your living space, especially dangerous in homes with respiratory-sensitive occupants.

FAQs About Air Duct Cleaning in Agoura Hills
Yes. Smoke and ash infiltration doesn’t require structural damage. The fine particulate from the Woolsey Fire passed through outdoor HVAC intakes and settled into duct interiors across thousands of surviving Agoura Hills homes. Many owners assumed “no visible damage” meant clean ducts and never scheduled inspection. We routinely find gray-black ash layers in these systems, sometimes years later. Call (469) 972-3151 for a video inspection and we’ll show you exactly what’s inside.
No. Fogging a scented or antimicrobial mist through ducts does nothing to remove embedded ash, char particulate, or compacted debris. It wets the contamination down and masks odor for a week or two. Real cleaning requires mechanical agitation and negative-air extraction to physically remove material from the duct wall. We don’t sell fogging treatments because they don’t solve the actual problem Agoura Hills homeowners face. Our written price covers source removal, not cover-up.
Agoura Hills sits in a wildland-urban interface with canyon corridors that funnel Santa Ana winds directly into outdoor air intakes. The chaparral ash and fine dust load here is measurably higher than in flatland Thousand Oaks or San Fernando Valley floor locations. Combined with original 1970s-1990s flex ductwork that’s now prone to sagging and joint separation, Agoura Hills homes accumulate and trap debris at a faster rate. It’s geography and housing age, not imagination.
The majority of Agoura Hills residential ductwork was installed during the late 1970s through early 1990s buildout, making it 30-45 years old. Original flex duct of this era degrades differently than modern materials: the liner becomes brittle, wire helixes fatigue, and sagging creates debris traps at low points. Our technicians adjust brush speed and agitation pressure to clean thoroughly without tearing aged material, and we inspect every joint for separation that would recontaminate the system immediately after cleaning.
For most Agoura Hills homes, every three to five years under normal conditions. Homes with Woolsey Fire exposure, repeated Santa Ana smoke events, or respiratory-sensitive occupants should consider every two to three years with a video inspection in between. The recurring chaparral ash load here means maintenance intervals should be shorter than in coastal or basin cities with cleaner outdoor air. Call (469) 972-3151 and we’ll recommend a schedule based on your specific home’s history and location.
