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 Altadena
Air duct cleaning in Altadena, CA typically runs $350-$650 for a full residential system and is usually completed in one scheduled visit with a written price confirmed before work begins. Most Altadena homes need cleaning every 2-3 years, though properties in our canyon wind corridor or those affected by the January 2025 Eaton Fire often benefit from shorter intervals with HEPA-rated protocols.
We’re the local Air Duct Cleaning team that serves Altadena from our Los Angeles office, dispatching background-checked, uniformed technicians to neighborhoods from the foothills below Echo Mountain down through the bungalow districts near Loma Alta Park. We know the difference between a routine maintenance job and the post-disaster remediation that many Altadena homes now require. Our phone is answered by a live person, 24/7, at (469) 972-3151.
Why Kestrel Air Duct Cleaning Is Altadena’s Preferred Air Duct Cleaning Company
Altadena homeowners have dealt with enough uncertainty since the Eaton Fire. We’ve built our reputation here by eliminating the biggest one: what you’ll actually pay. Our written price arrives before any vent is touched, and our 365-Day Done Right Promise goes on every invoice, not just the ones where we remember to mention it.
We answer calls live around the clock because duct contamination doesn’t follow business hours, especially in a community recovering from wildfire smoke intrusion. Our crews know Altadena’s housing stock, the original craftsman bungalows along Mariposa Street with their attic-routed galvanized ducts, the mid-century ranches near the county line with sagging flex runs in hot crawl spaces. That familiarity means faster diagnosis and no time wasted figuring out how your system is laid out.
Dale Whitmore and our team have responded to more post-fire remediation calls in Altadena than anywhere else in our service area. The Kingswell Guarantee, founded in 2004, governs every visit: say the price, show up in the window we gave, leave the place cleaner, put the guarantee in writing, come back if it fails.
Air Duct Repair in Altadena
Air Duct Repair in Altadena addresses the physical damage that foothill conditions and the 2025 Eaton Fire inflicted on aging duct systems, from separated flex duct in hot attics to corroded metal runs where ash and moisture combined. Most repairs in Altadena run $200-$500 for localized fixes, with full section replacements reaching $800-$1,400 depending on attic accessibility and material type. We see the need most often in 1920s-1950s homes where original galvanized steel has thinned or where Santa Ana wind pressure has worked seams loose over decades.
Fire-Damaged Seals and Joints
Heat cycling from the Eaton Fire expanded and contracted metal duct seams, particularly in unconditioned Altadena attics where temperatures already swing hard between summer highs and winter lows. We replace failed mastic seals with fire-rated materials and mechanical fasteners rated for the temperature extremes these foothill attics produce.
Collapsed Flex Duct in Attic Runs
Original flex duct installed during later updates sags in Altadena’s steep-roof bungalows, creating airflow restrictions that strain HVAC equipment and trap debris. Our repair includes proper support strapping and, where needed, rigid metal replacement for the longest horizontal runs.
Ductwork Cleaning in Altadena
Ductwork Cleaning in Altadena removes accumulated debris from the complete supply and return network, not just the registers you can see. A typical full-system cleaning in Altadena runs $350-$650, with larger homes or post-fire remediation reaching $750-$1,200 depending on contamination level and system complexity. We use Rotobrush rotary brush systems for agitation at the duct wall, Nikro negative-pressure units for source removal, and Abatement Technologies HEPA filtration to keep loosened particles out of your living space during the process.
Post-Fire HEPA Protocol
After the Eaton Fire, standard cleaning isn’t adequate for many Altadena homes. Our post-disaster protocol seals the system under negative pressure, uses camera inspection to locate ash deposits in return plenums and supply boots, and verifies clearance with after photos. The heavy-metal-laden ash from combusted building materials requires containment procedures that routine maintenance doesn’t.
Mountain Dust and Pollen Removal
Altadena’s position in the San Gabriel foothills means ductwork loads faster with inorganic particulate than flatland systems. Our brush agitation dislodges this compacted material, and negative-air extraction pulls it out rather than pushing it deeper into the house through leaky attic ducts.
Trusted Brands We Service in Altadena
We stock parts and filtration products from Aprilaire, Abatement Technologies, and Guardsman for Altadena customers who want to maintain clean air between professional cleanings. Aprilaire media air cleaners install at the return plenum to capture incoming particulate before it enters the duct network. Abatement Technologies HEPA portable units can run during and after remediation to scrub airborne particles that escape containment. Guardsman UV products address biological growth in the moist sections of Altadena’s older systems. Our technicians carry common Aprilaire and Guardsman components on every Altadena truck, so most filter upgrades or minor part replacements happen same-visit without a return trip.
Common Air Duct Cleaning Problems We See in Altadena Homes
- Gray-white ash in return plenums from the Eaton Fire. Even homes that appeared undamaged often harbor a thin, dense coating of combustion-derived ash deep in the return air path. Register-level cleaning never reaches it. We find it with camera inspection and remove it with sealed-system source removal.
- Leaky attic ducts redistributing debris. The original supply and return runs in Altadena’s 1920s-1950s homes were routed through unconditioned attic spaces and sealed with materials that degrade. Negative pressure during cleaning is essential; without it, agitation just blows ash and dust into the living space through every gap.
- Accelerated debris loading from canyon winds. Altadena’s position at the base of the San Gabriel Mountains creates a natural funnel for Santa Ana events. Ductwork here accumulates mountain dust, wildfire particulate, and inorganic debris faster than comparable homes in Pasadena or South Pasadena, shortening the realistic cleaning interval.
- Long, hidden dryer vent paths through attics. Many Altadena bungalows route dryer exhaust through extended attic runs that clog with lint and create fire hazards. We inspect and clean these during the same visit because the lint pathway is part of the same ventilation system.
Pricing for Air Duct Cleaning in Altadena, CA
Most full residential duct cleaning jobs in Altadena run $350-$650 for a complete supply and return system. Post-Eaton Fire remediation with HEPA protocols and extended camera inspection typically ranges $750-$1,200 depending on system size and contamination level. Commercial systems in Altadena’s small professional buildings start around $800 and scale with square footage and access complexity.
What moves the price: number of supply and return vents, whether the system includes a main trunk line that needs separate attention, attic accessibility in steep-roof craftsman homes, and whether we’re addressing standard maintenance or post-fire ash remediation. Dryer vent cleaning as an add-on runs $120-$250 for the long attic-terminated runs common in older Altadena properties.

FAQs About Air Duct Cleaning in Altadena
Altadena homes typically need cleaning every 2-3 years versus 3-5 for similar homes in Pasadena. The canyon wind funnel at the base of the San Gabriel Mountains pushes more mountain dust, wildfire ash, and inorganic particulate into Altadena ductwork, and the 2025 Eaton Fire added combustion-derived ash with heavy-metal content to many systems. Call (469) 972-3151 and we’ll assess your specific interval based on your home’s age, location, and any fire exposure.
Yes. Most standing Altadena homes have a thin gray-white ash coating deep in return air plenums and supply boots that no amount of surface cleaning reaches. The smoke event drove fine particulates through gaps in the building envelope while HVAC systems were running, distributing contamination throughout the duct network. Our camera inspection finds it, and our sealed-system HEPA protocol removes it. Call (469) 972-3151 for a free assessment.
Post-disaster remediation in Altadena means sealing the duct system under negative pressure, running camera inspection to locate ash deposits, using rotary brush agitation and source removal to clear contaminated plenums and boots, and installing HEPA filtration at the air handler to capture residual airborne particulate. We document before-and-after conditions with photos, and we verify that the blower motor runs within normal temperature range afterward. The 365-Day Done Right Promise covers our remediation work if any smoke odor returns.
Yes. Properties on Altadena’s outer edges with unpaved access, wood heat supplements, or detached shop buildings with their own systems accumulate dust and pollen faster than interior neighborhoods. The realistic cleaning interval shortens to 18-24 months. We schedule adequate time for longer drives and bring portable negative-air units for outbuilding systems that aren’t tied to the main house HVAC. Call (469) 972-3151 to discuss your specific property layout.
Dryer vent cleaning is a separate service that we can bundle with duct cleaning during the same appointment. In Altadena’s 1920s-1950s homes, dryer vents often terminate through long, hidden attic paths that clog with lint and create significant fire hazards. We inspect the full lint pathway with a camera and clear it with rotary tools and negative-air extraction. Adding dryer vent cleaning to your duct appointment costs $120-$250 depending on run length and accessibility.
