Why Altadena Homes Are Different
Altadena sits where the San Gabriel Mountain canyons open onto the Los Angeles basin, and that geography creates conditions no neighboring city duplicates. Santa Ana winds accelerate through those canyons, carrying oak pollen, mountain grit, and during fire season, ash directly into homes with outdoor air intakes or poorly sealed return plenums. The foothill elevation means cooler nights than Pasadena below, so furnaces and heat pumps cycle more frequently year-round, pulling outdoor air through ductwork at a higher rate than flatland systems.
The housing stock compounds this. Altadena’s 1920s-1950s Craftsman bungalows and Spanish Colonial Revival cottages often still run on galvanized sheet-metal ductwork or early flex duct that has never been professionally cleaned. Decades of accumulated debris, combined with the fine gray-black ash technicians are still finding in ducts months after the Eaton Fire, creates a contamination profile that standard residential equipment cannot fully address.
Air Duct Cleaning in Altadena
Our Air Duct Cleaning crews serve Altadena from our Los Angeles office, dispatching to the 91001 and 91003 ZIP codes with equipment matched to this city’s specific challenges. We treat a 1920s Craftsman bungalow near Christmas Tree Lane differently than a mid-century ranch below Altadena Drive - the age and material of your ductwork determines our approach, not a standard playbook.
Residential Duct Cleaning
Altadena’s housing stock tells a story. Those 1920s Craftsman bungalows near the historic district often still run on original galvanized sheet-metal ductwork that hasn’t seen a brush in forty years. The mid-century ranches below Altadena Drive have aging flex duct, crumbling at the seams. Standard residential cleaning runs $350-$550 for homes up to 2,500 square feet, and $550-$850 for larger estate properties. 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.
Post-Wildfire Decontamination
The January 2025 Eaton Fire tore through Altadena’s Very High Fire Hazard Severity Zone with devastating specificity. Homes that survived almost certainly pulled toxic smoke, char ash, and hazardous particulates deep into their duct systems. Post-Eaton Fire decontamination with HEPA extraction and proper hazardous waste disposal runs $650-$1,200. 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.
Can you clean original galvanized ducts in 1920s Altadena bungalows without damaging them?
Yes, with adjusted technique. 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. Call (855) 401-6006 for an inspection - estimates are free.
Dryer Vent Cleaning in Altadena
Dryer vent cleaning in Altadena typically costs $149-$289 for a standard single-family home, with most jobs completed in one visit. Our Dryer Vent Cleaning crews know the foothill streets from Loma Alta Drive to the ranch homes along the Eaton Canyon wash, and we start every job with a camera inspection to document what we’re dealing with before a single tool is lifted.
Vent Cleaning and Lint Removal
We serviced a mid-century ranch home on Loma Alta Drive where the dryer vent had never been cleaned since the original 1960 construction. Inside, we found decades of compacted lint mixed with Eaton Fire ash that had infiltrated through a roof-mounted vent cap. Our crew used Rotobrush agitation followed by HEPA vacuuming, then installed a Guardsman bird guard to prevent future debris entry. A standard dryer vent cleaning runs $149-$289, while deep cleaning with HEPA extraction for post-fire ash runs $225-$375. That combination - mechanical agitation, HEPA-rated extraction, and physical barrier installation - is now our standard protocol for Altadena post-fire cleans.
Vent Rerouting
Many Altadena homes were built with dryer vents that terminate through the roof or crawlspace in ways that no longer meet current safety guidance. In the hillside neighborhoods above Altadena Drive, we’ve rerouted vents from roof terminations to exterior wall caps, shortening the run and eliminating the climb onto tile roofs that Santa Ana winds already batter. Vent rerouting typically runs $289-$450 in Altadena, depending on access and materials needed.
After the Eaton Fire, should I get my dryer vent cleaned even if my home didn’t burn?
Yes. Homes in Altadena that survived the fire still drew smoke, ash, and hazardous particulates through roof-mounted vent caps and imperfect duct seals. Our technicians are finding duct interiors coated with fine gray-black ash that smells of smoke even months later. Standard residential cleaning equipment won’t remove it safely - we use HEPA-rated extraction and proper disposal. Call (855) 401-6006 to schedule.
HVAC Cleaning in Altadena
Our HVAC Cleaning team serves homes from the historic bungalows near Mariposa Street to the hillside estates above Loma Alta Drive, with pricing disclosed before we lift a single tool.
Evaporator Coil and Blower Cleaning
The evaporator coil in your indoor air handler is where cooling actually happens, and in Altadena it’s working harder than most. The foothill elevation means cooler nights that cause more frequent HVAC cycling year-round, and each cycle pulls outdoor particulates through the system. After the Eaton Fire, we’re finding coils coated with fine ash that restricts heat transfer and forces your compressor to run longer. Evaporator coil cleaning runs $180-$290, and blower cleaning runs $150-$240. We use foaming cleaners and low-pressure rinses that won’t damage aging aluminum fins, followed by camera verification so you see the difference.
Condenser Cleaning
Your outdoor condenser coil takes the heat your indoor system collects and dumps it outside. Altadena’s position at the mouth of San Gabriel Mountain canyons means Santa Ana wind events drive oak debris, pollen, and grit directly into those coil fins. During fire season, ash clogs the fins and insulates them, reducing efficiency by 20% or more. Condenser cleaning in Altadena runs $140-$220, with additional charge if the unit requires disassembly for deep cleaning.
After the Eaton Fire, does standard duct cleaning remove wildfire smoke residue from my Altadena home’s ducts?
No. Standard residential duct cleaning equipment is not designed to capture the fine particulates and toxic combustion byproducts, including potential asbestos and lead paint residues, that the Eaton Fire deposited in Altadena homes. We use HEPA-rated Abatement Technologies systems with sealed containment and proper disposal protocols for post-fire jobs. Call (855) 401-6006 to discuss whether your home needs this level of decontamination - estimates are free.
Duct Repair & Sealing in Altadena
Duct repair and sealing in Altadena typically runs $280-$650 for most residential jobs, with our Duct Repair & Sealing team carrying materials for both 1920s Craftsman crawlspaces and mid-century ranch attics. We answer calls live at (855) 401-6006, and we show up when we say.
Mastic Sealant Application
Mastic sealant is the only proper way to seal metal duct joints in Altadena’s conditions. Standard duct tape fails within weeks here - the heat cycling, the ash residue from fire events, and the concentrated Santa Ana winds degrade adhesive-backed products fast. A typical mastic sealant application in Altadena runs $280-$420 for a single system with accessible joints. We brush on UL-181-rated mastic, let it cure to a flexible, heat-resistant skin, and verify with camera inspection that every seam is sealed.
Metal and Flex Duct Repair
Altadena’s 1920s-1950s housing stock contains original galvanized sheet-metal ductwork that has never been professionally serviced. These systems corrode at seams, separate at joints, and collect decades of debris. Metal duct repair in Altadena typically costs $340-$580 depending on linear feet and accessibility. Flex duct in tight Craftsman crawlspaces kinks, compresses, and tears under the strain of repeated HVAC cycling; flex duct repair runs $180-$320 per run, including proper support strapping to prevent future compression.
Will sealing my ducts help with smoke odor from the Eaton Fire?
Sealing alone won’t remove existing odor, but it’s essential after proper decontamination. Sealed ducts prevent reintroduction of outdoor particulates during Santa Ana events. We HEPA-vacuum and treat duct interiors first, then seal to lock in cleanliness. In homes near the burn scar, we’ve found this two-step approach is the only lasting solution. Call (855) 401-6006 for a camera inspection - estimates are free.
Air Quality & Sanitizing in Altadena
Air quality and sanitizing in Altadena starts with understanding what this foothill community has been through. After the January 2025 Eaton Fire, homes from the historic Craftsman district near Loma Alta Drive to the estate properties along the San Gabriel Mountain frontage need more than standard cleaning - they need decontamination. Our Air Quality & Sanitizing team serves all of Altadena with HEPA-rated equipment and proper disposal protocols for post-wildfire conditions.
Odor Removal and Decontamination
Smoke odor in Altadena homes after the Eaton Fire isn’t a surface problem - it’s embedded in ductwork, insulation, and HVAC components. On a post-Eaton Fire job in the historic Craftsman district near Loma Alta Drive, we found a 1950s ranch home with original galvanized ductwork coated in fine gray-black ash carrying toxic combustion byproducts. We deployed Rotobrush HEPA equipment and Abatement Technologies negative air scrubbers to fully purge the system. Post-wildfire decontamination with HEPA extraction runs $450-$780 depending on system size and ash load. Standard cleaning won’t touch this.
Air Purifier Installation
After we decontaminate a system, installing a whole-home air purifier gives Altadena homeowners ongoing protection against what the Santa Ana winds will bring next. We specify Honeywell and Aprilaire units sized to your duct system’s airflow. In Altadena’s Very High Fire Hazard Severity Zone, with downslope wind events that drive grit, pollen, oak debris, and ash directly into outdoor intakes, a passive system isn’t enough. Whole-home air purifier installation runs $650-$1,200 depending on model and duct integration complexity.
My Altadena home survived the Eaton Fire but smells smoky. Can duct sanitizing fix that?
Yes, in most cases professional duct decontamination eliminates persistent smoke odor when it’s sourced in the HVAC system. The fine gray-black ash we’re finding in Altadena ducts months after the fire carries odor compounds that standard cleaning won’t remove. We use HEPA-rated extraction followed by source-specific deodorizing treatment, then verify with camera inspection that ash residue is gone. Call (855) 401-6006 for a free estimate - we’ll show you exactly what we found.

What Altadena Customers Say
"Did the dryer vent while they were here for a small add on price. The dryer finishes a load in one cycle now instead of two."
- Adam Pruitt"The allergies in this house had been bad since we moved in. It has been a couple of months since they did the ducts and it is noticeably better. Not a miracle, but real."
- Vikram Rao"Two guys, about three hours, plastic down at every register, and they wiped the vent covers before putting them back."
