We’ve been driving up the 210 and winding through Altadena’s foothill streets since 1984. From the Craftsman bungalows along Mariposa Street to the estate properties perched above Loma Alta Drive, we know the ductwork hiding behind these walls. Altadena’s unincorporated status means no city building department of its own, but that doesn’t mean your home deserves anything less than code-conscious work. Our technicians live in the San Gabriel Valley. They know Santa Ana wind season starts in fall and doesn’t let up until spring. They know which Altadena neighborhoods sat in the smoke plume for days after the January 2025 Eaton Fire. That local knowledge changes how we clean your ducts - not just whether we clean them.

Our Air Duct Cleaning Services in Altadena
Residential Duct Cleaning
Altadena’s housing stock tells a story. Those 1920s Craftsman bungalows near the historic district? Many still run on original galvanized sheet-metal ductwork that hasn’t seen a brush in forty years. The mid-century ranches below Altadena Drive? Aging flex duct, crumbling at the seams. Our Air Duct Cleaning team treats each system according to its age and material - no one-size-fits-all approach. We use Rotobrush agitation for heavy debris buildup and HEPA-negative-air machines when we’re pulling out wildfire ash that standard equipment would simply recirculate.
Commercial Duct Cleaning
Altadena’s commercial corridors along Lake Avenue and Fair Oaks Avenue include medical offices, small retail, and professional services that can’t afford downtime or compromised indoor air. We schedule around your hours, contain our work zones, and provide before-and-after video documentation for your records. Post-Eaton Fire, several Altadena businesses needed immediate duct decontamination before reopening - we completed most in a single overnight visit.
Supply Duct Cleaning
Supply ducts push conditioned air into your living spaces. In Altadena homes near the burn scar, we’ve found these lines particularly compromised - fine ash works its way past filters and settles in supply runs, then blows into rooms every time the system cycles. Our supply duct cleaning includes register removal, line brushing, and negative-air extraction. We check every boot and connection for ash infiltration.
Return Duct Cleaning
Return ducts pull air back to your HVAC unit. They’re your system’s lungs, and in Altadena they’re working overtime. Cooler foothill nights mean more frequent cycling year-round. Santa Ana winds drive outdoor particulates through any gap in your envelope. Return ducts in older Altadena homes often sit unsealed in crawl spaces or attics, pulling in dust, rodent debris, and - after January 2025 - wildfire ash. We seal what we can and clean what we can’t seal.
Full System Cleaning
This is what most Altadena homes need after the Eaton Fire. Full system cleaning covers supply and return ductwork, the air handler cabinet, blower assembly, and coil - the complete air path. We were called to a Craftsman bungalow on Mariposa Street two months after the Eaton Fire. The ducts were coated with fine gray-black ash carrying combustion byproducts; we used a Rotobrush with HEPA filtration and disposed of the waste per hazmat protocols, restoring indoor air quality. That level of contamination demands more than a standard residential cleaning. It demands equipment rated for hazardous particulate and technicians trained in proper disposal - not just a shop vac and good intentions.
Video Inspection
Every job starts and ends with camera verification. You see what we see - the ash buildup, the debris, the before and after. In Altadena’s current environment, this isn’t a sales tool. It’s documentation. Homeowners near the burn scar have used our video records for insurance claims and peace of mind. The camera doesn’t lie, and we don’t hide what it shows.

Trusted Brands We Service in Altadena
We clean systems built with equipment from Aprilaire, Abatement Technologies, and Guardsman - brands that serious HVAC contractors specify, not the consumer-grade units sold at big-box stores. For post-wildfire decontamination in Altadena, we deploy Abatement Technologies HEPA air scrubbers and Rotobrush brush-and-vac systems with sealed HEPA collection. We don’t show up with rental equipment or improvised tools. The brands matter because your air matters. And when we’re working in a Very High Fire Hazard Severity Zone with confirmed toxic ash contamination, the equipment specification isn’t negotiable.
Common Air Duct Cleaning Problems We See in Altadena Homes
- Insufficient HEPA filtration during post-fire cleaning, leaving toxic ash in duct runs. We’ve been called back to Altadena homes where a previous service used standard residential equipment and simply moved the ash around. The smell of smoke persisted. Proper post-fire work requires HEPA-rated negative air machines and sealed waste disposal - anything less leaves hazardous particulate behind.
- Neglected outdoor air intakes drawing Santa Ana wind-driven debris. Altadena’s position at the mouth of mountain canyons means these winds hit harder here than in Pasadena below. Uncovered or poorly screened intakes pull in grit, pollen, oak debris, and ash that recontaminates clean ducts within weeks. We inspect and clean every intake as part of our full system service.
- Standard methods failing on complex estate duct runs. The sprawling foothill properties above Loma Alta Drive often have duct systems with multiple branches, zoning dampers, and extended runs that standard equipment can’t fully purge. We’ve developed specific protocols for these layouts - longer setup time, multiple access points, and verified airflow at every register.
- Aging galvanized ductwork in historic homes. Those beautiful Craftsman bungalows near the Christmas Tree Lane district often contain original metal duct that corrodes from the inside out. Aggressive cleaning damages it; insufficient cleaning leaves decades of buildup. We adjust our brush selection and vacuum pressure to the material - preserving what can be preserved, documenting what needs replacement.
Pricing for Air Duct Cleaning in Altadena, CA
Here’s what honest pricing looks like in Altadena’s current market:
| Service | Typical Range |
|---|---|
| Standard residential duct cleaning (up to 2,500 sq ft) | $350-$550 |
| Large home or estate property (2,500-5,000 sq ft) | $550-$850 |
| Post-wildfire decontamination with HEPA extraction | $650-$1,200 |
| Dryer vent cleaning (add-on or standalone) | $150-$250 |
| Video inspection only | $125-$175 |
What moves you within these ranges: square footage, number of registers, accessibility of duct runs, and contamination level. A 1920s bungalow with original galvanized duct and no access panels takes longer than a 1990s ranch with modern flex duct and generous crawl space. Post-Eaton Fire decontamination requires HEPA equipment, hazmat disposal fees, and often multiple passes - that’s reflected in the upper range.
We disclose your exact price before work begins. The number on the phone is the number on the invoice. No bait coupons, no upsell at the door. We also honor a permanent 5% Senior and Veteran discount, and our $89 Seasonal Tune-Up can identify whether your ducts need full cleaning before you commit to the larger service.

FAQs - Air Duct Cleaning in Altadena
We use HEPA-rated negative air machines and sealed waste disposal protocols, not standard residential cleaning equipment. The fine gray-black ash we find in Altadena ducts after the Eaton Fire can carry combustion byproducts from structures that contained asbestos and lead paint - materials common in older buildings that burned. Our technicians wear appropriate PPE, collect waste in sealed containers, and dispose through licensed hazardous waste channels. We verify removal with post-cleaning camera inspection. Call (855) 401-6006 if you smell smoke from your vents - estimates are free.
Yes - Altadena homeowners typically need cleaning every 2-3 years rather than the standard 3-5 year interval. The Santa Ana winds are stronger and more concentrated here than in flatland cities because of the San Gabriel Mountain canyon effect. These downslope winds drive grit, pollen, oak debris, and during fire season, ash directly into outdoor intakes and any imperfectly sealed ductwork. If your home is in the foothills above 1,000 feet or near recent burn areas, annual inspection is prudent. Call (855) 401-6006 to schedule a video inspection - we’ll tell you if cleaning is actually needed.
We can, with adjusted technique. Original galvanized sheet-metal ductwork in Altadena’s historic homes - common in the Craftsman bungalows near Christmas Tree Lane - corrodes from the inside over decades. We use softer brush agitation and reduced vacuum pressure, prioritizing preservation over speed. If the camera reveals structural failure, we’ll document it and discuss repair options before proceeding. We’ve cleaned dozens of these systems in Altadena without damage. Call (855) 401-6006 for a free assessment - we’ll look before we commit to anything.
Yes. The estate properties above Loma Alta Drive and along the northern ridges often have complex duct systems with multiple zones, extended runs, and dampers that standard residential equipment can’t fully purge. We bring larger-capacity HEPA machines, create additional access points where needed, and verify airflow at every register before we leave. Most estate jobs run $550-$850 for standard cleaning, $850-$1,200 for post-fire decontamination. Call (855) 401-6006 - we’ll walk the property and quote exactly.
We deploy Rotobrush brush-and-vac systems with sealed HEPA collection and Abatement Technologies HEPA air scrubbers for post-wildfire work in Altadena. These are the same brands serious restoration contractors use - not rental equipment or improvised setups. The sealed HEPA collection is critical because standard residential machines exhaust fine particulate back into your home. For hazardous ash containing potential asbestos and lead combustion byproducts, that’s unacceptable. We also use Aprilaire media filters as replacements where original filters are compromised. Call (855) 401-6006 to discuss your specific situation - estimates are free.
Altadena’s position at the base of the San Gabriel Mountains creates air quality challenges no neighboring city faces in the same way. The January 2025 Eaton Fire deposited toxic smoke and ash into duct systems across residential neighborhoods - a hazard that demands specialized decontamination, not standard cleaning. Combined with concentrated Santa Ana winds and older housing stock that hasn’t seen professional duct service in decades, Altadena homeowners need technicians who understand this specific environment. That’s what we provide. Camera verification. HEPA-rated equipment. Upfront pricing. And a 90-Day Done Right Promise - in writing, no arguing.
