Our Air Duct Cleaning Services in Altadena
Residential Duct Cleaning
Altadena’s homes were built to last, but their ductwork often wasn’t. The Craftsman bungalows near Mendocino Street and the ranch homes off New York Drive frequently retain original or early-retrofit flex runs and fiberglass duct board that trap particulate like a filter that never gets changed. After the Eaton Fire, this legacy ductwork became a reservoir for sub-micron ash. Our residential cleaning uses professional-grade Rotobrush equipment to agitate and extract debris from these older systems without damaging fragile connections. Most Altadena homes are completed in a single visit.

Commercial Duct Cleaning
Small commercial properties along Lake Avenue and near the Altadena Golf Course face the same foothill particulate load as residences, compounded by higher occupancy and continuous HVAC operation. We clean supply and return systems for offices, retail spaces, and small medical clinics with the same camera-verified approach: inspect before, clean thoroughly, inspect after. Documentation is provided for property managers and insurance records.

Supply Duct Cleaning
Supply ducts deliver conditioned air to every room, and in Altadena, they’re the primary pathway for post-fire ash recirculation. We recently cleaned a 1940s Craftsman on Calaveras Street where the furnace ran during the Eaton Fire. Our Rotobrush video inspection showed a grey-black ash coating in all supply ducts, confirming contamination that standard filters couldn’t address. Cleaning supply lines requires accessing each register, running agitation tools to the trunk line, and verifying with post-clean camera footage.

Return Duct Cleaning
Return ducts pull air back to the HVAC unit, and in Altadena’s older homes, these often run through unconditioned attics where Santa Ana wind debris enters through gaps and degraded seals. Return duct cleaning addresses the intake side of the system, including the return plenum and filter rack area. For homes near the mountain front, this is where chronic dust accumulation is heaviest.

Full System Cleaning
A full system cleaning addresses supply ducts, return ducts, trunk lines, plenums, and the air handler itself. In Altadena’s post-Eaton Fire environment, this is the only approach that addresses the complete contamination pathway. Partial cleaning leaves ash in the system to recirculate. We recommend full system cleaning for any Altadena home where the HVAC operated during or immediately after the fire event.

Video Inspection
Every job starts and ends with camera inspection. Our technicians feed high-resolution cameras through the ductwork to document conditions before cleaning and verify results after. For Altadena homeowners dealing with insurance claims related to the Eaton Fire, this footage provides dated, visual proof of contamination and remediation. It’s not a claim; it’s a record.

Common Air Duct Cleaning Problems We See in Altadena Homes
- Post-fire ash recirculation. Homeowners replace filters but don’t realize post-fire ash has coated duct interiors, requiring full system cleaning. The ash is sub-micron, meaning it passes through standard pleated filters and embeds in duct walls.
- Degraded fiberglass duct board. Old fiberglass duct board in Altadena’s vintage homes traps ash and soot, making surface cleaning ineffective. The porous material holds contamination that agitation and extraction must address directly.
- Santa Ana wind debris infiltration. Santa Ana winds funnel mountain debris into outdoor intakes, leading to chronic particulate buildup that routine maintenance misses. Altadena’s position against the San Gabriel Mountain front makes this measurably worse than in lower-elevation Pasadena.
- Oversized flex runs with poor airflow. Many Altadena retrofits from the 1970s and 1980s used oversized flex duct that creates turbulent airflow, causing debris to settle in low-velocity sections rather than reaching the filter.

FAQs - Air Duct Cleaning in Altadena
Yes, if your HVAC system ran during or immediately after the fire, you likely pulled contaminated air through your ducts. The Eaton Fire generated sub-micron ash that traveled miles on Santa Ana winds, and any home with active air circulation in ZIP codes 91001 or 91003 is potentially affected. Our camera inspections have found grey-black ash coating in supply ducts of homes that appeared completely undamaged from the outside. Call (844) 685-6342 to schedule a video inspection and know for certain.
Wildfire ash is chemically distinct from household dust, containing combustion byproducts and sub-micron particles that embed in duct walls rather than settling loosely. Standard household vacuums and filter replacements cannot remove it. Our post-fire remediation uses HEPA-contained agitation and professional extraction to address embedded contamination, followed by camera verification. The process takes longer than standard cleaning and requires different equipment. Call (844) 685-6342 for a free estimate on post-fire duct remediation.
Many Altadena homeowners have received coverage for duct cleaning as part of smoke damage claims, but policies vary significantly. We provide dated, camera-verified documentation of contamination and remediation that supports insurance submissions. We do not bill insurance directly; payment is due at service completion, and we furnish detailed invoices for reimbursement. Contact your adjuster to confirm your specific coverage. Call (844) 685-6342 to discuss documentation options.
Altadena sits directly against the San Gabriel Mountain front, making it a concentrated impact zone for Santa Ana wind events that funnel mountain chaparral dust and, during fire years, heavy ash loads straight into outdoor air intakes. Pasadena’s lower elevation and greater distance from the mountain front result in measurably lower particulate loads. Even in non-fire years, Altadena’s foothill position means ductwork accumulates debris faster than in flatland communities. Call (844) 685-6342 to discuss an appropriate maintenance schedule for your location.
Cleaning the return grille removes visible surface debris but does not address contamination inside the ductwork. Our camera inspections consistently find grey-black ash coating in supply ducts far from the return grille, in areas inaccessible to household tools. The contamination pattern is invisible from the outside and requires professional agitation and extraction. We recommend against partial approaches that leave ash circulating in the system. Call (844) 685-6342 for a full system assessment.
