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 Topanga
Air duct cleaning in Topanga typically runs $450-$850 for a full residential system and is scheduled within a few days of your call. Most Topanga homes need the full source-removal approach because canyon conditions here pull in wildfire ash, coastal salt air, and chaparral pollen that surface cleaning alone won’t touch. We’re Morton’s Air Duct Cleaning, and our crews work Topanga regularly, from the rustic cabins off Old Topanga Canyon Road to the hillside homes near Tuna Canyon Park. Dispatch is coordinated from our Los Angeles office, but the trucks that roll up your steep driveway are stocked and staffed for canyon access. Call (323) 918-4345 for a free written estimate before any work starts.
Why Morton’s Air Duct Cleaning Is Topanga’s Preferred Air Duct Cleaning Company
We’ve been serving Topanga since 2005 as part of the Cedarwell family, and our reputation here was built on jobs where other crews couldn’t finish. In a community where duct runs snake through unsealed crawlspaces and 1960s redwood cabins have non-standard access points, our technicians arrive with Rotobrush agitation tools, Nikro HEPA containment systems, and the patience to work around your home’s quirks. Reviews from Topanga customers consistently mention the photo we leave behind, the shoe covers we put on before stepping inside, and the written price we provide before touching anything.
Response time to Topanga is typically two to four business days for standard scheduling, though we keep slots open for post-wildfire remediation when Santa Ana winds have pushed smoke through return vents. Every technician is background-checked, uniformed, and trained to the Cedarwell C.A.R.E. values, which means quiet tools during nap hours and pet-safe product choices where available. We know the difference between a Calabasas subdivision duct run and a Topanga canyon retrofit, and we price accordingly, not generically.
Vent Cleaning in Topanga
Vent cleaning in Topanga addresses the supply and return vents where coastal salt air, chaparral pollen, and wildfire particulates first enter your living space. In Topanga’s 1950s-1970s cabins and artist compounds, vents are often original to retrofitted HVAC systems, mounted in odd locations to accommodate non-standard construction, and surrounded by flexible ductwork that wasn’t sealed against the chaparral environment. A proper vent cleaning here removes the visible buildup and, more importantly, reaches the debris lodged in the transition between vent cover and duct trunk. Typical vent cleaning in Topanga runs $180-$340 per system when done as part of a full cleaning, or $220-$400 as a standalone service for homes with limited access.
Supply Vent Focus
Supply vents push conditioned air into your rooms, but in Topanga they also pull in whatever’s outside when the system’s off and the dampers don’t seal. We remove each cover, clean the boot and first few feet of duct, and check for gaps where salt-laden canyon air infiltrates. This matters more here than in sealed valley homes.
Return Vent Recovery
Return vents are the intake lungs of your system, and in Topanga they’re often positioned low on walls where ash settles after wildfire events. Our crew cleans the grille, the filter housing, and the return trunk back to the air handler, using HEPA-contained tools so nothing recirculates during the job.
Air Duct Repair in Topanga
Air Duct Repair in Topanga fixes the gaps, separations, and crushed flexible runs that turn your duct system into an open window on the Santa Monica Mountains. Because Topanga’s housing stock includes so many owner-built and retrofitted structures, ductwork was often installed for convenience, not longevity, flexible lines routed through unsealed crawlspaces and crevices that draw in chaparral pollen and coastal salt air. When those flex ducts separate at seams or sag on steep canyon lots, your HVAC works harder, your bills climb, and outdoor contamination bypasses the filter entirely. Typical air duct repair in Topanga ranges from $350-$750 for localized sealing and reinforcement, or $900-$1,800 for extensive re-routing and replacement of damaged flexible runs.
Seal Inspection and Repair
We pressurize the system and use smoke pencils to find leaks, then seal accessible joints with mastic and mechanical fasteners. In Topanga’s humid crawlspaces, tape alone fails within a season, so we don’t use it as a primary seal. The goal is stopping infiltration at the source, not just treating symptoms.
Structural Reinforcement
Steep lots mean ducts hang at angles they weren’t designed for. We add supports, replace crushed sections, and re-secure flex runs so they don’t kink or tear where they pass through foundation gaps. This extends system life and prevents the repeated contamination that makes cleaning temporary.
Trusted Brands We Service in Topanga
Our trucks carry professional-grade equipment from Rotobrush, Nikro, and Aprilaire, brands we chose because they perform under the demanding conditions we find in Topanga’s canyon homes. Rotobrush agitation tools break loose ash and particulate that has bonded to duct liners after wildfire exposure. Nikro HEPA filtration systems maintain negative pressure containment so nothing escapes into your living space during cleaning. Aprilaire media filters and upgrade components are stocked for same-day installation when your existing filter housing can’t handle the particle load this environment generates. We don’t rent entry-level gear by the day. We own and maintain our equipment, which means faster turnaround for Topanga customers and no waiting for a parts run to the valley.
Common Air Duct Cleaning Problems We See in Topanga Homes
- Wildfire ash saturation in return trunks. After events like the 2018 Woolsey Fire, many Topanga homeowners returned to find their HVAC had run for hours before evacuation, drawing smoke and pyrolytic particles deep into duct liners. Surface vacuuming doesn’t remove this bonded layer; full source removal with agitation and HEPA containment does.
- Mold and microbial growth in unsealed crawlspace flex duct. Topanga’s coastal humidity plus salt air creates conditions not seen in drier inland areas. Flexible ductwork running through foundation gaps stays damp, and the organic load from surrounding chaparral provides food for growth that recirculates through vents.
- Crushed or separated duct on steep canyon lots. Non-standard access points and angled installs mean ducts sag, kink, or pull apart at seams. Techs without canyon experience often declare these unreachable and clean only what’s visible, leaving contamination in hidden sections.
- Leaky returns pulling in outdoor pollen loads. The Santa Monica Mountains National Recreation Area surrounding Topanga generates heavy seasonal pollen from coastal sage scrub species. Without sealed returns and proper filtration, this biological load enters continuously, overwhelming standard maintenance schedules.

FAQs About Air Duct Cleaning in Topanga
Full source removal is necessary, not standard surface cleaning. Wildfire smoke and pyrolytic particles bond to duct liners and can recirculate for years; only agitation-based cleaning with HEPA containment removes this layer. Call (323) 918-4345 for a free inspection and written quote.
Coastal salt air plus humidity from canyon microclimates creates condensation in unsealed flex duct that drier, better-sealed valley homes don’t experience. This moisture, combined with organic pollen loads from chaparral, accelerates microbial growth. We address this with seal repair, not just cleaning.
Yes. Our crews carry extension equipment and are trained for non-standard access points common in Topanga’s 1950s-1970s cabins and owner-built structures. We inspect with cameras first to locate duct runs, then choose the right approach rather than cleaning only what’s easy to reach.
Duct cleaning physically removes particulate from duct surfaces; sanitizing fog deposits a chemical layer that may kill surface organisms but does not remove bonded ash, mold, or pyrolytic particles. In Topanga’s post-fire environment, fogging masks odors while the actual contamination remains. We don’t sell fogging as a substitute for source removal.
Most Topanga homes benefit from cleaning every three to five years under normal conditions, with inspection recommended within six months of any significant wildfire exposure. Heavy pollen seasons and unsealed ductwork may shorten this interval. Call (323) 918-4345 to discuss your home’s specific timing.
