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 runs $340 – $610 for a typical single-system home, and most jobs wrap up in four to six hours. That’s a whole-system price that covers the supply, return, blower, and air handler. We are Cardinal Air Duct Cleaning, part of the Relay Home Co. family (founded 2005). Our crew knows Agoura Hills, from the canyon-edge lots off Kanan Road to the track homes near Chumash Park and the newer builds along Thousand Oaks Boulevard. Call (737) 727-2314 and you’ll get a live person, a written price before work starts, and before-and-after photos of your own ducts.
Why Cardinal Air Duct Cleaning Is Agoura Hills’s Preferred Air Duct Cleaning Company
Homeowners across Agoura Hills call us because we don’t do phone quotes per vent and then “discover” extra charges once the van is in the driveway. We quote one flat price per system. You agree to it before we unload a single tool. What changes the number for an Agoura Hills home is what’s actually inside the ducts: how many returns, how deep the runs go, and how much wildfire ash and canyon dust has settled along the way.
Our technicians are background-checked and show up in uniform with professional-grade equipment, not a truck-mounted shop vac. Rotobrush rotary brush systems, Nikro HEPA vacuums, and Abatement Technologies containment units. If the work isn’t right, our 365-Day Done Right Promise means we come back and correct it at no charge for a full year. That’s the longest-standing satisfaction window in the trade, and it applies to every job we book in Agoura Hills. No asterisks.
The Relay Standard is what you get when you book Cardinal. A live trackable arrival time, a written price handed to you before any duct is touched, and before-and-after photo documentation. You see what we saw. You decide if it’s done right. That’s the whole standard.
Air Duct Cleaning Services in Agoura Hills
Air Duct Cleaning Services in Agoura Hills mean source removal, not surface dusting. We open the supply and return registers, run a camera to document what’s in the system, then set up negative pressure with HEPA filtration before agitating the ducts with rotary brushes. Negative pressure means the loosened debris gets pulled straight into the vacuum, not blown back into your living room. The camera doesn’t lie, and the photos you get at the end show what was actually removed.
Full System Cleaning
A proper full system cleaning covers the supply ducts that push conditioned air into your rooms, the return ducts that pull air back to the air handler, the blower motor and housing, the evaporator coil if it’s accessible, and the plenum boxes. Most Agoura Hills homes have between ten and twenty registers. We don’t charge per register. One price per system, agreed before work starts.

Supply and Return Duct Cleaning
Returns run dirtier in this part of the Santa Monica Mountains corridor. They’re the side of the system that pulls air back in, and the same air that carries smoke and dust off the 101 corridor and canyon edges. Supply ducts stay cleaner but still pick up fine dust and debris, especially in homes with pets or remodel history. We clean both directions fully; half a cleaning leaves the air handler fighting whatever we didn’t remove.

HVAC Duct Cleaning in Agoura Hills
HVAC Duct Cleaning in Agoura Hills goes further than register-level work. We’re pulling the blower motor, inspecting the coil, and checking the filter slot so the whole mechanical path is documented. Canyon-driven fine ash is lighter than typical household dust. It settles deeper, into the return run and straight into the air handler, rather than clinging to the register face. We see Aprilaire filters loading up in weeks instead of months on canyon-edge homes. That’s a sign the air handler itself is caked with particulate.
Air Handler and Blower Cleaning
The blower motor and wheel collect whatever the filter misses, or whatever bypasses the filter slot entirely if the housing is loose or the previous filter was wrong-sized. We clean the blower assembly because a balanced blower lasts longer and moves air more efficiently. The camera inspection documents what we found before and after.
Filter and Filtration Check
Agoura Hills homes near the open space or along the 101 corridor should run MERV 11 or higher for most of the year, and some benefit from Aprilaire media filters. We check the filter slot, the filter type, and the air handler condition during every cleaning. If your filtration is undersized, we’ll tell you plain. We won’t sell you a cleaning your system doesn’t need.
Trusted Brands We Service in Agoura Hills
We service and clean systems built around Rotobrush, Nikro, and Abatement Technologies equipment, and we recommend filtration from Aprilaire, Honeywell, and Guardsman for homes close to canyon corridors. Our techs know the filter slots, blower housings, and return configurations common in Agoura Hills homes. Stocking common media filters and replacement parts locally means a faster turnaround when your system needs a small fix during the cleaning, not a two-week backorder. You’ll know the tech’s name before they knock, and the tools they carry are the ones listed on your booking confirmation.
Common Air Duct Cleaning Problems We See in Agoura Hills Homes
- Wind-driven canyon ash in return runs. Homes near Kanan Road, Chesebro Canyon, and the Liberty Canyon corridor catch fine particulate from Santa Monica Mountain winds and 101 traffic. It packs into return ducts past the filter slot, especially when gaps exist around filter frames.
- Wildfire-season smoke residue. Agoura Hills sits in a high-fire-risk zone. When smoke seasons hit, ultra-fine ash coats blower motors and evaporator coils. Standard filter changes don’t remove what’s already inside the ductwork or air handler.
- Pet hair and dander in supply ducts. Many Agoura Hills homes have active households with dogs that shed into returns. Combined with dry mountain air, it compresses into mats inside the return run over a few years.
- Post-remodel construction dust. Agoura Hills has ongoing renovations across neighborhoods like Morrison Ranch and Old Agoura. Drywall dust and sawdust get pulled through returns before filters are installed properly. That dust coats every downstream component.
Pricing for Air Duct Cleaning in Agoura Hills, CA
A typical single-system home in Agoura Hills runs $340 – $610 for full source-removal cleaning, supply and return included. Larger homes with two air handlers or unusually long canyon-wind-driven return runs can run higher. What affects cost is real: square footage, number of air handlers, how much particulate is packed in the system, and any repair we find during the job. Any repair gets a written price and a free second visit if it fails, per the 365-Day Done Right Promise. We never charge per vent. Estimates are free and they come in writing before any work begins. Call (737) 727-2314 to get an exact quote for your Agoura Hills home.

FAQs About Air Duct Cleaning in Agoura Hills
Every 3 – 5 years for most Agoura Hills homes. Homes close to canyon corridors or the 101 may need it every 2 – 3 years because wind-driven ash and wildfire smoke particulate settles deeper than typical household dust. If you’re unsure, we can run a camera inspection and tell you honestly whether a cleaning is worth doing now. Call us at (737) 727-2314 and we’ll walk you through what we’d check and what it costs.
Per system, always. We quote one flat price for your whole duct system, agreed in writing before work starts. We never charge per vent, because that’s how bait-and-switch pricing works in this trade: a low per-vent number that balloons once the tech counts twenty registers. You’ll know your full price before we unload anything. Call (737) 727-2314 for a written estimate.
Yes. Every job includes before-and-after photos of your own ducts, taken with the same camera we use for inspection. You see the return run before agitation, and you see it after the HEPA vacuum pulls the debris out. No wondering if anything happened. Call (737) 727-2314 and ask about the camera inspection.
Yes, they change what we expect to find and how deep we clean. Fine canyon-driven ash is lighter than household dust and settles into the return run and air handler rather than clinging to register faces. We spend more time on the return side and the blower assembly in Agoura Hills than in a coastal city where the particulate is heavier and more visible at the register. Call (737) 727-2314 and we’ll explain what that means for your specific home.
It’s often worth doing, yes. Dryer vents collect lint the same way duct runs collect particulate, and on canyon-edge Agoura Hills lots, they also pull in fine dust. We clean dryer vents as a separate service, but we can bundle the quote so you see both numbers before scheduling. Call (737) 727-2314 and we’ll give you one written estimate for the whole set.
How We Actually Clean Air Ducts in Agoura Hills
Down in Old Agoura, a homeowner on a canyon-edge lot called us after her Aprilaire filter was loading up in weeks instead of months. Our tech ran a camera inspection through the return, found the run packed with wind-driven ash and lint past the filter slot, and set up negative pressure with HEPA filtration before agitating the supply and return ducts with our Rotobrush whips. She got before-and-after photos of her own ducts, the filter change interval went back to normal, and we agreed one flat price per system before we started.
Most of Agoura Hills sits in the Santa Monica Mountains corridor along the 101, where canyon winds and wildfire seasons push fine ash and dust into return ducts. That fine particulate is lighter than typical household dust, so it settles deeper into the return run and air handler rather than clinging to the register faces. We follow NADCA standards, maintain negative pressure throughout the job, and use HEPA filtration so loosened debris goes straight into the containment unit. The camera inspection documents what’s in the system before we start and what’s there after we finish. If a system doesn’t need cleaning, we’ll tell you. Some newer Agoura Hills homes with sealed systems just need the Aprilaire filter and blower motor checked, not a full source-removal job. We won’t manufacture work that isn’t there.
