Fast, Reliable Air Duct Cleaning Across Calabasas
Air duct cleaning in Calabasas is less about routine dust and more about what the Santa Monica Mountains send through your returns. The canyon geography here traps wildfire ash and smoke longer than coastal LA, which means a standard brush-only cleaning often isn’t enough. We bring Rotobrush contact-cleaning systems and Nikro HEPA negative-pressure filtration to every job, because fine particulate from the Woolsey burn scar and annual Santa Ana events ends up in ductwork that generic equipment can’t fully clear. Homeowners here need source removal and smoke-odor treatment, not a quick vacuum pass. Call (833) 589-9715 for a free estimate. We answer 24/7. Fast dispatch from 7am to 7pm, Sunday through Friday.
Why Calabasas Homeowners Call Onyx Duct Cleaning for Air Duct Cleaning
The homes that define Calabasas – the custom Mediterraneans in The Oaks, the gated streets of Calabasas Hills, the canyon-adjacent properties off Mulholland and Las Virgenes – have duct systems that reward thorough work and punish shortcuts. Long flexible runs above vaulted ceilings hide debris that a quick brush won’t reach. Multiple HVAC zones mean one system cleaned is not a house cleaned. Contractors who treat a 6,000-square-foot custom home like a 1,500-square-foot tract house leave ash in the second system and the odor returns within weeks.
We stock and run Abatement Technologies filtration equipment, which is the kind of contamination-containment gear restoration and abatement crews use. That matters when the debris in question is charred wildfire particulate, not household dust. Our technicians understand whole-system air quality – they work across Honeywell and Aprilaire filtration setups – and they don’t just clean around a problem. If a duct run is compromised, we repair it. Air duct cleaning here works best when the company doing it can also fix what’s wrong with the ductwork itself.
Stan Merrick founded Onyx Duct Cleaning in 2013. The company has been serving Southern California for 13 years, and the Calabasas market is one we know street by street. When a homeowner in Calabasas calls about smoke odor after a wind event, we know which systems and which duct layouts we’re likely walking into.

Residential Air Duct Cleaning in Calabasas
Residential Air Duct Cleaning in Calabasas typically involves a full-system approach across every active HVAC zone, because most homes here run two or three of them. We clean supply ducts, return ducts, plenums, and registers using Rotobrush contact-cleaning to dislodge debris at the duct wall, then hold the system under Nikro HEPA negative pressure so extracted particulate is captured, not recirculated into living space. For homes near open canyon edges off Las Virgenes or Mulholland, that extraction step is the difference between clean air and ash settling back onto furniture within a day.
When does a Calabasas homeowner need it? After a Santa Ana wind event, after nearby wildfire smoke settles into the returns, after a renovation that sent drywall dust through the system, or when a family member’s allergies spike each time the HVAC cycles. We also recommend a full cleaning after a new HVAC install, because construction debris and old-duct contamination get pulled into fresh equipment fast.
A typical residential full-system cleaning in Calabasas runs $450-$900 per system depending on square footage, number of returns, and how much debris is present. Homes with three zones and long flexible runs sit at the higher end. The written estimate sets the final price, always.
Full System Cleaning
Every trunk, branch, return drop, and plenum box gets cleaned, not just the registers you can see from the hallway. For Calabasas homes with vaulted ceilings and ductwork buried above finished space, this is the only way to actually clear the system.
Video Inspection
We run a camera through the main trunks and problem runs before and after. You see what was in there and what’s gone. Documentation matters for work you can’t see, and Calabasas homeowners rightly expect it.
Commercial Air Duct Cleaning in Calabasas
Commercial Air Duct Cleaning in Calabasas covers office buildings, retail spaces, restaurants, and property management communities across the 91302 corridor. Commercial systems run longer hours, move more air, and pull in whatever the canyon winds push across the 101. Restaurants near The Commons, medical and professional offices along Park Granada, and community facilities in gated HOA properties all need documentation that the air path is actually clean – not just a service invoice.
We run the same contractor-grade setup on commercial jobs that we do on large custom homes: Rotobrush contact-cleaning, Nikro HEPA negative pressure, and camera documentation before and after. The scale is bigger and the scheduling usually works around business hours, but the goal is the same – remove what’s in the ducts and prove it’s gone.
Commercial pricing in Calabasas typically runs $0.18-$0.35 per square foot depending on system count, access, and contamination level. A single-story office suite with one rooftop unit costs less per square foot than a multi-zone building with long runs and hard-to-reach plenums. The estimate is free and the written quote sets the final price.
Property Management Work
HOAs and property managers in Calabasas regularly schedule duct cleaning after wildfire smoke events or as part of unit turnover. We provide before-and-after photo and video documentation so a property record exists for what was cleaned and when.
Restaurant and Retail Systems
Kitchen-adjacent ducts and high-traffic retail returns collect grease vapor and particulate faster than standard systems. We schedule around operating hours and provide documentation that satisfies lease and inspection requirements.
Trusted Brands We Service in Calabasas
Calabasas homes run a wide range of HVAC and filtration setups, and we service the equipment that’s actually in these houses. Honeywell whole-home filtration, Aprilaire media cabinets, and Guardsman components all show up regularly on our Calabasas jobs. Knowing these systems as a whole – not just the duct interior – means we can tell you whether a filter cabinet or return layout is working against the cleaning we just did. We don’t install HVAC systems and we don’t sell filter subscriptions. We clean what’s upstream of your equipment and we tell you honestly what’s downstream. Stan Merrick’s team has 13 years of experience with the brands Calabasas homes actually use.
Common Air Duct Cleaning Problems We See in Calabasas Homes
- Ash in the return plenum after Santa Ana events. Canyon-facing homes off Mulholland and Las Virgenes pull fine charred particulate into the returns each time the winds blow. A return plenum that looks clean can hold a quarter-inch of fine ash against the filter frame.
- Unbalanced cleaning across multiple zones. A house with three HVAC systems needs all three cleaned. Cleaning only the downstairs system and leaving ash in the upstairs returns means the odor comes back the first warm day. Per-system pricing exists because per-system work is the only honest way to quote it.
- Debris hidden in long flexible runs above vaulted ceilings. These runs sag, collect debris in the low points, and are invisible from the register. Camera inspection catches what a brush pushed blindly through will miss. This is a Calabasas-specific frustration given how many custom homes have exactly this layout.
- Smoke odor that returns after a basic cleaning. Brush-and-vac without HEPA negative pressure stirs fine ash around rather than removing it. The odor dissipates for a week, then returns. We treat supply and return ducts with a smoke-odor encapsulant where needed, and we hold the system under negative pressure the whole time.

FAQs About Air Duct Cleaning in Calabasas
Wildfire smoke carries fine charred particulate and volatile compounds that bind to duct walls and plenum surfaces far more aggressively than household dust. In Calabasas, the canyon geography traps that smoke, so it settles and re-settles through multiple HVAC cycles. The result is a layer of fine ash that standard brush-only cleaning doesn’t fully remove. We use HEPA negative-pressure extraction and smoke-odor encapsulant on systems that have been through a nearby fire event. Call (833) 589-9715 for a free estimate and we’ll tell you honestly what your system needs.
Yes, if you want the smoke odor or dust problem gone. Each HVAC zone has its own supply and return path. Cleaning one zone leaves debris in the other two, and the odor or dust returns the moment that zone cycles on. We price per system, so you know exactly what each zone costs, and you decide what gets done. But a partial clean on a multi-zone Calabasas home usually means calling us back.
You should expect before-and-after camera footage of the main trunks and problem runs, plus a written summary of what was found and what was removed. We run a camera through the system before we start and after we finish. For Calabasas homeowners with long flexible runs above vaulted ceilings, that footage is the only way to verify the work was actually done. We show you the system, not just the invoice.
Yes, when the cleaning captures the charred particulate and then treats the duct surfaces where smoke compounds have adhered. We pull visible debris from return plenums and trunk lines using Rotobrush contact-cleaning, hold the system under Nikro HEPA negative pressure so nothing recirculates, and apply a smoke-odor encapsulant to supply and return ducts. After a Santa Ana event near Calabasas, this is often the only thing that stops the odor from returning each time the system cycles. Call (833) 589-9715 and we’ll assess what your system needs.
Most Calabasas homes benefit from a full-system cleaning every 3-5 years, but homes in canyon-adjacent areas off Mulholland and Las Virgenes should plan a cleaning after any significant Santa Ana event or nearby fire. Ash that settles into the returns doesn’t leave on its own. If you can smell smoke when the system cycles on, the ducts need attention now, not on a calendar schedule. A free estimate will tell you where you stand.
