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 $380-$620 for a single-system home and $950-$1,400 for properties with two or three air handlers, with most jobs completed in one scheduled visit. Our Air Duct Cleaning crews coordinate dispatch from the Los Angeles office and carry Rotobrush, Nikro, and Abatement Technologies equipment specifically configured for canyon homes. Call (469) 972-3151 for a written estimate before any work begins.
We’ve worked in the steep, winding streets above Topanga Canyon Boulevard long enough to know that no two duct systems here are alike. A 1960s owner-built home in Fernwood might have flex duct cobbled together over decades, while a post-Woolsey rebuild on Tuna Canyon Road runs brand-new sealed ductwork. That split personality is exactly why we map every system by hand and price per air handler, not per house. Dale Whitmore built our Kingswell Guarantee around this reality: the written price covers exactly what we inspect, nothing hidden, nothing added at the door.
Why Kestrel Air Duct Cleaning Is Topanga’s Preferred Air Duct Cleaning Company
Our reputation in Topanga was earned house by house, often after homeowners had already been burned by a flat-rate coupon that ballooned once the van arrived. We don’t work that way. The Kingswell Way requires our technicians to put the full scope and price in writing before touching a single vent cover. That standard has kept our callback rate low and our referral rate high in a community where neighbors talk.
Topanga residents call us because we answer the phone. A live person, 24 hours a day. No automated queue, no “press 1 for service.” When you’re staring at a return-air grille coated in rust-orange residue after a Santa Monica Mountains fire, you want a human who understands what Phos-Chek looks like and why standard duct cleaning won’t touch it.
Response time to Topanga runs same-week for standard appointments, with scheduling coordinated from our Los Angeles dispatch office. We don’t promise same-day because duct cleaning is a scheduled, thorough job, not an emergency patch. What we do promise is arrival inside the window we give you, background-checked uniformed technicians, and a 365-Day Done Right Promise documented on every invoice.
Local knowledge matters here. We know which Topanga streets still rely on original 1970s flex duct, where the marine layer lingers until noon, and which homes sit in the direct path of Santa Ana ash intake. That context changes how we clean, what we look for, and what we document.
Air Duct Repair in Topanga
Air Duct Repair in Topanga addresses the cracked flex duct, separated trunk lines, and fire-damaged returns that canyon conditions accelerate. Most repairs run $180-$450 for localized fixes and $600-$1,100 for extensive trunk-line replacement in multi-wing homes. We see the worst damage in older owner-built structures where ductwork was never designed to modern static-pressure specs, and in post-fire rebuilds where temporary repairs were never swapped for permanent solutions.
Fire-Damaged Returns and Seals
After any significant Santa Monica Mountains fire, we inspect return-air pathways for Phos-Chek infiltration and heat-degraded seals. Aerial retardant is corrosive to standard duct tape and mastic. We replace compromised connections with code-compliant materials and verify static pressure before closing up.
Crawl-Space Duct Replacement
Raised-foundation homes in Topanga often run original flex duct through dirt-floor crawl spaces where moisture and rodent activity converge. When we find collapsed or perforated runs, we map replacement routing by hand, the same way we mapped the original system, because no two of these homes follow a standard plan.
Ductwork Cleaning in Topanga
Ductwork Cleaning in Topanga means source removal of the dust, ash, mold, and fire-retardant residue that canyon living pushes into HVAC systems. A single-system residential job runs $380-$620; homes with two or three air handlers range $950-$1,400. We use Rotobrush rotary brush agitation to dislodge debris from duct walls, then Nikro negative-air extraction to pull it out under controlled pressure, with Abatement Technologies HEPA filtration keeping particles out of your living space during the process.
Post-Fire Source Removal Protocol
When we detect Phos-Chek residue or elevated ash loading, we extend HEPA-filtrated negative pressure through the entire return pathway and document pre- and post-cleaning with video inspection. Standard brush agitation alone can redistribute fine fire particulates. We don’t stop until the camera shows clean metal.
Multi-System Coordination
Three separate air handlers means three separate source-removal setups, three filter changes, and three documentation packages. We price each system individually so you know exactly what each wing of your house received. No flat-rate guesswork that hides the third system behind vague language.
Trusted Brands We Service in Topanga
We clean and maintain ductwork connected to every major HVAC manufacturer, and we stock Honeywell, Aprilaire, and Guardsman filtration products for Topanga homeowners who want to maintain clean air between service visits. Our trucks carry replacement media for Aprilaire whole-house filters and Guardsman register seals, so most filter upgrades happen same visit without a return trip. For homes battling post-fire particulate loading, we often recommend upgrading to a denser Aprilaire media filter with a pressure-drop check to confirm the blower motor can handle the load. Dale Whitmore reviews every multi-system proposal personally to make sure filtration specs match each air handler’s capacity.
Common Air Duct Cleaning Problems We See in Topanga Homes
- Phos-Chek residue in return-air pathways. After Santa Monica Mountains fire events, we routinely find rust-orange or pink coating on grilles and filter housings. Standard dust removal won’t touch it. We identify it with visual inspection and camera verification, then run extended HEPA-filtrated source removal until the duct wall reads clean.
- Mold colonization in uninsulated crawl-space flex duct. Topanga’s morning marine layer funnels moisture inland from Malibu, and raised-foundation homes with original 1960s-70s ductwork see condensation inside uninsulated runs. We locate active growth with camera inspection, then clean and recommend insulation or dehumidification to break the cycle.
- Ad-hoc multi-system layouts with no documentation. Owner-built homes in areas like Fernwood and upper Topanga often have three air handlers added wing by wing over decades, with supply and return trunks that defy standard mapping. We trace every run by hand before cleaning so nothing gets skipped.
- Santa Ana ash loading in outdoor HVAC intakes. When fall winds reverse the canyon’s airflow, fine chaparral particulates pressurize outdoor condenser coils and nearby fresh-air intakes. A single event can load a clean duct system with material that standard filters won’t catch.
Pricing for Air Duct Cleaning in Topanga, CA
Most single-system Topanga homes run $380-$620 for full source-removal cleaning. Two-system properties range $650-$950, and three-system canyon homes with multiple air handlers typically fall between $950-$1,400. Air duct repair adds $180-$450 for localized fixes or $600-$1,100 for extensive trunk-line replacement. What moves you within those ranges: system count, duct accessibility (crawl space vs. attic), post-fire residue requiring extended HEPA protocol, and whether video inspection reveals damage needing repair before cleaning proceeds.

FAQs About Air Duct Cleaning in Topanga
We look for rust-orange or pink Phos-Chek residue on return-air grilles and filter housings, and we run camera inspection through the first several feet of return duct to check for particulate loading that standard household dust doesn’t produce. If we find it, we switch to extended HEPA-filtrated negative-air extraction until post-cleaning video shows clean duct walls. Call (469) 972-3151 to schedule an inspection.
Yes. We price each air handler as its own scope of work because each requires separate negative-pressure setup, brush agitation, source removal, and filter service. A single flat quote for the house would hide the real labor and equipment involved in cleaning systems two and three. You’ll see a line-item price for each system in writing before we start.
It can, especially in older uninsulated flex duct running through raised-foundation crawl spaces where morning moisture condenses on cool metal or duct walls. We find active mold most often in 1960s-70s owner-built homes in Fernwood and along canyon roads where the marine layer lingers past noon. Camera inspection confirms whether you’re seeing mold, dust, or both.
Before-and-after photos from our camera inspection, a written scope of work listing every system cleaned, the equipment used on each, and your 365-Day Done Right Promise documented on the invoice. If we find damage or fire residue, we include those images with explanatory notes. You get physical proof of what happened inside hidden spaces.
They do. When fall Santa Ana conditions reverse the canyon’s normal airflow, fine chaparral ash and particulates pressurize outdoor air intakes and condenser cabinets at levels flatland LA doesn’t experience. A single wind event can load a recently cleaned system. We check for this specifically during fall service calls and recommend appropriate filtration upgrades if intake loading is chronic.
