Fast, Reliable Air Duct Cleaning Across Agoura Hills
Air duct cleaning in Agoura Hills typically runs $350-$850 for a full residential system, and most jobs are completed in a single visit with same-day or next-day scheduling available. We answer calls 24 hours a day at (855) 401-6006, and our crews are on the road throughout the 91301 and 91376 ZIP codes daily.
We’ve worked Agoura Hills homes for over 42 years, from the original 1970s tracts off Chesebro Road to the newer builds climbing toward the Santa Monica Mountains. This city sits in wildfire country. The Woolsey Fire burned through in November 2018, and the Santa Ana winds still blow chaparral ash and pollen through return-air grilles every autumn. That combination - fire-retardant residue, aging fiberglass duct board, and recurring particulate events - creates problems you won’t find in a flatland manual. Our Air Duct Cleaning team knows the local housing stock, the access constraints of alley-loaded townhomes off Kanan Road, and the contamination signatures that show up in foothill duct systems. We don’t guess. We camera-inspect before we touch a tool.

Most of our Agoura Hills calls come from homeowners who’ve lived in the same house for twenty-plus years and plan to stay. They’ve been burned by low-bid contractors before. They want the job done right and never thought about again. We built our business for exactly that customer.
Our Air Duct Cleaning Services in Agoura Hills
Residential Duct Cleaning
Agoura Hills’s single-family homes - mostly built in the 1970s and 1980s - carry original or early-generation fiberglass duct board and flex duct systems now 40 to 50 years old. These systems sag, their inner liners deteriorate, and they trap decades of accumulated chaparral dust, oak pollen, and sage particulates. Our residential cleaning starts with a full video inspection to assess liner condition before we select equipment. We use Rotobrush and Nikro HEPA vacuum systems that clean thoroughly without destroying fragile fiberglass. Most Agoura Hills homes are completed in one visit.
Commercial Duct Cleaning
Commercial properties along Agoura Road and Kanan Road - medical offices, retail suites, small professional buildings - face the same Santa Ana particulate loading as residences, but with higher occupancy and stricter liability. We schedule around business hours, contain our work areas, and provide before-and-after video documentation for facility managers and property owners. Our crew is background-checked and uniformed, and we carry the commercial-grade equipment from Abatement Technologies needed for larger trunk systems.
Supply Duct Cleaning
Supply ducts push conditioned air into your living spaces. In Agoura Hills, these lines often run through hot attics where degraded flex duct develops leaks at sag points, pulling in unfiltered attic air. We seal accessible joints during cleaning and flag deterioration that needs repair. If your supply registers blow visible dust when the system kicks on, that’s a signal worth investigating.
Return Duct Cleaning
Return ducts are where Agoura Hills homes show their scars. These lines draw air back to the HVAC unit, and in this foothill environment they pull in everything the Santa Ana winds deliver - fine ash, pollen, smoke particulates, and in fire-zone properties, aerial fire-retardant residue. Return Duct Cleaning is our most requested service in 91301 for good reason. We inspect the return plenum, the filter housing, and the full return trunk with a camera before we begin. In homes that survived the Woolsey Fire, this is where pink or rust-red retardant slurry hides.
Full System Cleaning
Full System Cleaning covers supply ducts, return ducts, the main trunk lines, the plenum, and the air handler cabinet. For Agoura Hills homes with post-fire contamination or decades of accumulated chaparral debris, this is the only approach that actually solves the problem. We don’t spot-clean and declare victory. The full system gets inspected, cleaned, and re-inspected on camera. If the job isn’t right, our 90-Day Done Right Promise covers it.
Video Inspection
Every job starts and ends with Video Inspection. We run a lighted camera through your complete duct network and show you the footage. In Agoura Hills, this often reveals fire-retardant residue, liner degradation, or flex duct sagging that homeowners didn’t know existed. The after-cleaning video proves the work. You keep the record. No claim without proof.

Trusted Brands We Service in Agoura Hills

For filtration upgrades, we specify Aprilaire and Honeywell media filters and electronic air cleaners - the same brands serious HVAC contractors use.

Common Air Duct Cleaning Problems We See in Agoura Hills Homes
- Fire-retardant residue in return plenums. Technicians working the 91301 ZIP regularly find pink or rust-red aerial fire-retardant slurry from the 2018 Woolsey Fire crusted inside return-air plenums and filter housings of homes that outwardly show no fire damage. This contamination signature is almost never seen outside active fire-perimeter communities, and it requires specialized extraction - not standard brushing.
- Skipped return-side cleaning in tight-access townhomes. In alley-loaded townhomes off Kanan Road, technicians often skip thorough return-side cleaning because of tight crawlspace access, leaving ash and retardant embedded in flex duct sagging spots. We don’t skip. We bring the right equipment for confined spaces.
- Recirculated chaparral ash during Santa Ana events. When Santa Ana winds hit, homeowners close windows and rely on HVAC recirculation. If the return plenum wasn’t cleaned after the Woolsey Fire or previous seasons, they recirculate fine chaparral ash directly into living spaces. The system becomes a distribution network for contamination.
- Damaged fiberglass duct board from aggressive cleaning. Older fiberglass duct board systems in 1970s tract homes on Chesebro Road shed liner particulates when cleaned with high-pressure methods. Inexperienced crews can worsen indoor air quality instead of improving it. We assess liner condition first and select low-impact equipment accordingly.

FAQs - Air Duct Cleaning in Agoura Hills
The most reliable sign is a persistent smoke or chemical odor that returns each heating or cooling season, especially after the HVAC system has been idle. You may also notice pink or rust-red staining around return-air grilles or on old filters. We confirm it with a camera inspection of the return plenum and filter housing - that’s the only way to be certain, and we include this inspection free with any service call. Call (855) 401-6006 to schedule.
It’s not advisable. If your return system still carries fire-retardant residue or accumulated ash from previous seasons, the Santa Ana winds will force additional fine particulates through intake grilles, and your HVAC will recirculate the combined load throughout your home. We recommend a pre-season inspection and cleaning before October. Call (855) 401-6006 - estimates are free, and we’ll tell you exactly what we find.
Yes, if the liner is assessed first and the right equipment is selected. We use low-impact Rotobrush systems with controlled suction - never high-pressure air washing - on aging fiberglass duct board. If the liner is already degraded to the point of shedding, we’ll show you the camera footage and recommend repair or replacement options with upfront pricing. Call (855) 401-6006 for an inspection.
The Santa Ana winds stir up settled ash and particulate from previous fire seasons - including 2018 - that remains embedded in your return duct system. When the winds hit, these materials re-aerosolize and get drawn into the return plenum. The smell is real, and it’s coming from your ducts, not from outside. A thorough return-side cleaning with HEPA extraction removes the source. Call (855) 401-6006 for a free estimate.
Homes in the 91301 and 91376 ZIP codes should be inspected every 2-3 years under normal conditions, and annually if the home was within the Woolsey Fire perimeter or if occupants have respiratory sensitivity. After significant Santa Ana events, a return-duct check is prudent even if you’re not due for full service. We don’t sell unnecessary cleans - we camera-inspect and show you what we find. Call (855) 401-6006 to set up a schedule that fits your property.
On a recent job on Reyes Adobe Road, our crew opened a 1979-built home’s return-air plenum and found crusted pink fire-retardant slurry still lodged against the inner duct liner. We used a Rotobrush with HEPA vacuum to extract the residue, replaced the degraded flex duct from the attic to the main trunk, and installed a new Aprilaire MERV 13 filter housing - eliminating the smoke odor that had persisted since the Woolsey Fire.
We’re here when you need us. Calls are answered by a live person 24 hours a day at (855) 401-6006.
