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 Agoura Hills
Air duct cleaning in Agoura Hills typically runs $350 – $650 for a full residential system, with most jobs scheduled within a few business days and completed in three to five hours. We’re the Air Duct Cleaning in Agoura Hills crew that shows up in uniform, writes the price before touching equipment, and stands behind the work for a full year.
Our dispatch and scheduling are coordinated from the brand’s Los Angeles office, but our crews serve Agoura Hills locally and know the terrain. We’ve worked the hillside tracts off Kanan Road, the townhome clusters near the 101 corridor, and the canyon-edge streets of Old Agoura where flexible-duct runs from the 1980s snake through attics that most techs won’t crawl. Roy Castellanos leads Hollis Air Duct Cleaning, and our team understands that Agoura Hills isn’t a flatland suburb. Steep driveways, limited staging space, and WUI-zoned homes with ember-intrusion hardware all change how a cleaning gets done. Call (361) 326-5060 for a free estimate.
Why Hollis Air Duct Cleaning Is Agoura Hills’s Preferred Air Duct Cleaning Company
We’ve been in business since 2004 as part of the Garrison Partners family, and our track record predates most local competitors in the Agoura Hills market. That longevity matters because duct cleaning is an unregulated trade where fly-by-night operators bait with $99 coupons, then upsell once they’re inside your home. We don’t do that.
Our 365-Day Done Right Promise covers every job in writing. If the work fails within a year, we return and make it right at no charge, including a free second visit. No negotiation, no fine print.
Every technician is background-checked and uniformed. You know who’s walking into your home before they arrive. Phones are answered by a live person 24 hours a day, 7 days a week. No voicemail loops, no callback queues, no waiting until Monday.
We price in writing before any work starts. The number on the page is the number at the door. Period.
Air Duct Inspection in Agoura Hills
Air Duct Inspection in Agoura Hills starts with a camera run through your supply and return trunks, followed by register-by-register airflow and contamination mapping. Because about half of Agoura Hills sits in the designated Wildland-Urban Interface, ducts here often carry fine grey ash and chaparral grit pushed in by fall Santa Ana winds plus ember-intrusion screens over vents – meaning a cleaning should restore airflow without defeating that screening. A typical inspection in Agoura Hills runs $150 – $250, and we apply that fee toward your cleaning if you proceed.
Video Scoping of Original Flexible Duct
Most Agoura Hills homes were built in the 1970s – 1990s with flexible-duct runs in attics and crawlspaces. Our Rotobrush video systems let us spot collapsed sections, rodent damage, and ash accumulation without tearing into walls. You’ll see what we see.
Ember-Screen and Defensible-Space Check
WUI-zoned properties require vent screening that blocks ember intrusion during wildfire events. We inspect this hardware as part of every inspection. Removing it for cleaning and reinstalling it correctly is non-negotiable.
Residential Air Duct Cleaning in Agoura Hills
Residential Air Duct Cleaning in Agoura Hills means complete agitation and extraction of debris from supply ducts, return ducts, and the air handler, using negative-air containment so nothing escapes into your living space. The long dry season here, roughly May through October, draws canyon and chaparral dust and pollen through open windows and doors. Relative humidity stays too low to sustain biological growth, but fine mineral dust and wildfire ash accumulate steadily. A typical full-system residential cleaning in Agoura Hills runs $350 – $650 depending on system size and accessibility.
Negative-Air Method with HEPA Filtration
We use Nikro negative-air machines and HEPA filtration on every job. This isn’t a shop vac pushed down a register. The system creates suction at the air handler while rotary brushes dislodge debris, pulling contaminants out of the home entirely.
Townhome and Multi-Unit Protocols
Near the 101 corridor, denser townhome clusters often share building systems and restricted parking. We coordinate access, protect common areas, and never stir ash through registers without containment. Your neighbors won’t know we were there except for cleaner air.
Trusted Brands We Service in Agoura Hills
Our equipment roster includes Rotobrush rotary brush systems, Nikro negative-air machines, and filtration products from Honeywell, Aprilaire, Abatement Technologies, and Guardsman. These are the same tools commercial crews use, not hardware-store gear. For Agoura Hills customers, this means parts and compatible components are available without long waits. If your system uses Honeywell media filters or Aprilaire whole-house purifiers, we stock the correct replacements and install them during the same visit. No return trips, no mismatched parts.
Common Air Duct Cleaning Problems We See in Agoura Hills Homes
- Santa Ana ash packed in canyon-edge ducts. After the first strong Santa Ana winds of fall, we see a spike in calls from Old Agoura for ducts packed with fine grey ash and grit. Sustained down-canyon winds push wildfire debris and dry soil past standard vents, and only negative-air extraction with HEPA filtration removes it completely.
- Collapsed flexible duct in 1970s – 1990s hillside builds. Original flexible-duct runs in Agoura Hills attics degrade over decades. We find kinked, torn, or heat-damaged sections that restrict airflow and trap debris. Our inspection catches this before cleaning begins.
- Ember-intrusion screens clogged with chaparral dust. WUI-zoned homes have fine-mesh screens that protect against ember intrusion. These clog with dust and reduce airflow, but removing them without reinstalling correctly defeats fire protection. We clean without compromising safety.
- Shared dryer vent stacks in townhomes near the 101. Multi-unit buildings often share vertical dryer vents. Techs who won’t trace the full lint pathway from the air handler to the exterior termination leave fire hazards in place. We inspect the complete run.
Pricing for Air Duct Cleaning in Agoura Hills, CA
Here’s what air duct cleaning costs in the Agoura Hills market. These are whole-system ranges, not per-vent teaser prices that balloon at the door.
| Service | Typical Range in Agoura Hills |
|---|---|
| Air Duct Inspection | $150 – $250 (applied to cleaning if you proceed) |
| Residential Full-System Cleaning | $350 – $650 |
| Supply Duct Cleaning Only | $200 – $350 |
| Return Duct Cleaning Only | $200 – $350 |
| Dryer Vent Cleaning (standalone) | $125 – $225 |
| Duct Sealing with Mastic | $400 – $800 |
System size, attic accessibility, and contamination level affect where you land in these ranges. A 3,000-square-foot hillside home with original 1980s flexible duct and heavy Santa Ana ash loading takes longer than a 1,500-square-foot townhome near the 101 with newer metal trunk lines. We assess, write the price, and get your approval before starting. No per-vent pricing. No add-ons at the door. Call (361) 326-5060 for a free estimate.

FAQs About Air Duct Cleaning in Agoura Hills
It adds ember-intrusion vent screening and defensible-space hardware to our inspection checklist. We clean around and through these screens without removing or damaging fire-protection features, and we verify they’re intact before leaving. Crews unfamiliar with WUI requirements often skip this step, leaving homes vulnerable to ash re-intrusion and ember risk.
Shared stacks require tracing the full lint pathway from your air handler to the exterior termination. We inspect the complete run, not just your unit’s connection point. Many Agoura Hills townhomes near the 101 have never had this done. Call (361) 326-5060 and we’ll scope it.
Yes. Steep driveways, tight attic hatches, and crawlspaces with limited headroom are common in hillside builds off Kanan Road and in Old Agoura. Our techs carry compact Rotobrush systems and protective gear for these conditions. We assess access during your free estimate and plan equipment accordingly.
The hot-summer Mediterranean climate and long dry season draw fine mineral dust, oak pollen, and pine pollen through open windows. Canyon corridors channel this debris directly into homes. The dust is often too fine to see accumulating on furniture, but it builds in ductwork and restricts airflow over time.
Yes, especially for homes built in the 1970s – 1990s with original flexible duct. An inspection reveals collapsed sections, rodent damage, or ash loading that changes the scope and price. Our $150 – $250 inspection fee applies to your cleaning if you proceed. Call (361) 326-5060 to schedule.
In Old Agoura, a canyon-edge customer called after the first strong Santa Ana winds of fall complaining of grey ash dusting every register inside their 1980s hillside home. Our tech pulled the flexible-duct runs in the attic, used agitation tools and HEPA filtration under negative pressure to remove the fine ash from the supply and return ducts, then checked the ember-intrusion screens and air handler before sealing everything back up.
