Air Duct Cleaning Company in Altadena, CA
Air duct repair in Altadena means something different than it does in Pasadena or La Cañada. The homes here are older, the Santa Ana winds are real, and the 2025 Eaton Fire left ash and char inside duct systems across the entire valley floor, not just in the burn zone. We handle the full scope: cleaning, dryer vent work, and structural duct repair, so you don’t have to coordinate three contractors on a house that was built before HVAC was standardized. Call us at (866) 413-8552.
Why Altadena Homes Are Different
Altadena’s housing stock skews heavily toward pre-1950s single-family homes. Craftsman bungalows along Mariposa and Santa Rosa, Spanish Revivals in the President Streets, ranch-style houses on the east side near Eaton Canyon. A lot of them still have their original galvanized steel ductwork, and galvanized steel from 1947 is not the same as the sealed, insulated flex duct you’d find in a newer tract home. It corrodes from the inside, it leaks at the joints, and it’s often been retrofitted around additions and remodels, which means access panels are in strange places and runs are longer than they need to be.
Then there’s the climate. Altadena sits right at the base of the San Gabriel Mountains, and when the Santa Anas blow down the canyons in the fall, they carry fine dust, wildfire smoke, and airborne ash straight into attic returns and crawlspace registers. Homes even miles from the January 2025 Eaton Fire burn zone ended up with ash inside their supply ducts because the wind drove it through unsealed joints and gaps around register boots. We see this on nearly every inspection now. The older the home, the more entry points there are, and the more likely the duct interior needs both cleaning and repair rather than one or the other.
Homeowners in ZIP codes 91001 and 91003 should also know that many of the retrofitted systems around here were patched rather than replaced over the decades. A cleaning-only company will vacuum the debris and leave those patches alone. We repair what we find, because a clean duct that still leaks at the collar is pulling attic air into the living space the day after the job is done.

Our Main Altadena Services
Most Altadena homeowners call us for one of two things after an inspection or a fire-season wake-up call: a full air duct cleaning, or a dryer vent cleaning that has clearly been ignored for years. Both matter here, and both change in scope because of the local conditions.
Air Duct Cleaning in Altadena
Air duct cleaning in Altadena goes beyond routine dust removal, especially in the aftermath of the Eaton Fire. We remove fine ash, soot, pet dander, and decades of accumulated debris from supply and return ducts using Rotobrush and Nikro systems, negative air pressure, and agitation tools built for the job. Older galvanized ducts need a gentler touch than flex duct, and access ports often have to be cut into retrofitted systems and sealed afterward. Learn more about what a full cleaning includes on our Air Duct Cleaning in Altadena page.
Dryer Vent Cleaning in Altadena
Dryer vents in Altadena run through walls, crawlspaces, and sometimes up through the roof, and in older homes the runs are long and often improperly joined. Lint buildup in a restricted vent is a leading cause of residential house fires, and after years of Santa Ana dust settling into the vent pipe, blockage risk climbs. We clean the full run from dryer connection to exterior termination and check for damaged or disconnected sections. See the full service breakdown on our Dryer Vent Cleaning in Altadena page.
Air Duct Repair in Altadena
Air duct repair in Altadena is the service that fixes what cleaning alone cannot. Many of the homes here have original galvanized ducts with failed tape at the seams, crushed returns under the house, or sections that were disconnected during a remodel and never reconnected properly. After the Eaton Fire, we’re also finding smoke-damaged duct interiors and ash-coated insulation inside returns that should be removed and replaced rather than cleaned. Our team handles repairs as a standalone service, closing the gap most cleaning-only companies leave open. Learn more about the full scope on our Air Duct Repair hub page.
Air Duct Replacement
Signs you need it
Duct sections that are crushed, corroded through, or filled with fire ash and char that cannot be fully removed need replacement, not patching.
What it costs in Altadena
Full air duct replacement in Altadena typically runs $3,300 to $9,300, determined by the number of runs, whether the ducts are in the crawlspace or attic, and how much of the old metal has to be cut out.
How we do it
We remove the damaged sections, size replacement ductwork to match the system’s airflow requirements, install and seal new runs at every joint, and test the static pressure before we leave.
Ductwork Repair
Signs you need it
Rooms that never heat or cool evenly, whistling at the registers, or visible gaps and fallen tape at the duct joints mean air is escaping before it reaches the living space.
What it costs in Altadena
Localized ductwork repair in Altadena typically falls between $300 and $1,600, depending on how many leaks we find, where they are, and whether ducts need to be re-supported or reconnected.
How we do it
We seal the failing joints with mastic or foil-backed tape, re-hang sagging runs, replace crushed or disconnected sections, and verify airflow with an anemometer at the affected registers.
What Air Duct Repair Costs in Altadena
| Item | Typical range in Altadena |
|---|---|
| Localized ductwork repair | $300 – $1,600 |
| Air duct replacement (partial) | $1,800 – $4,700 |
| Full air duct replacement | $3,300 – $9,300 |
Older homes with retrofitted systems on the hillside streets tend to land on the higher end because access is tighter and materials have to match what’s already there. We quote one flat price before any work begins, so the number on the invoice is the number you approved.
Can you repair fire-damaged ducts in Altadena?
Yes, and this is now one of the most common jobs we do in Altadena. Ducts exposed to heavy smoke or ash from the Eaton Fire often need interior cleaning first, then inspection for char residue or compromised insulation. Where damage is too far gone, we replace the affected runs rather than seal over the problem.
How long does air duct repair take on an older Altadena home?
Most localized repairs finish in half a day. Full replacements on pre-1950s homes with difficult access can take one to two days. We schedule the work in advance and confirm the scope before starting, so you know the timeline before the van is in the driveway.
Brands We Service in Altadena
We stock and service equipment from Aprilaire, Abatement Technologies, and Guardsman, so routine parts are on the truck when we arrive. For less common components, our local supply network in the San Gabriel Valley keeps wait times short. See our brands for details on the equipment we maintain.

You’ll get one flat, upfront price per system before work starts, never a per-vent number that changes once we’re on site.

FAQs About Air Duct Cleaning Company in Altadena
No permit is needed for cleaning, sealing, or replacing duct sections in an existing residential HVAC system. If the work is part of a larger remodel that’s already permitted with Los Angeles County, the duct scope typically falls under that permit. We can confirm during the estimate.
Most single-system homes in Altadena take four to six hours for a full cleaning. Pre-1950s homes with original ductwork and difficult crawlspace access can run longer. We inspect the system first and give you a real time frame before we schedule.
Yes. Steeper streets and hillside crawlspaces are common in this city, and the equipment we use is set up for that. Rotobrush and Nikro systems are self-contained and powerful enough to maintain suction on longer runs at elevation, which matters in the upper Altadena neighborhoods.
If your ducts haven’t been looked at since before the fire, or if you know the last cleaning skipped the repair work, call us at (866) 413-8552 for a free estimate. We’ll tell you what’s in there, what it costs to fix, and what can wait. No pressure, just the actual condition of your system.

What Altadena Customers Say
"Found a disconnected run in the crawlspace while they were in there and told me about it rather than cleaning around it."
- Beatriz Torres"Job was done well and the house smells better. There was some dust knocked loose around a couple of the registers that I had to wipe down afterward."
- Marcy Bennett"Fair price and thorough work. They ran about an hour and a half past the estimated finish time, so don't schedule anything tight after."
- Colleen Barrett
