Air Duct Cleaning Company in Altadena, CA
Air Duct Repair is the service more Altadena homeowners call us for than any other, and the reason usually starts with the 2025 Eaton Fire. Homes that survived the burn scar are pulling fine grey ash through return plenums and into evaporator coils, while older flexible ductwork from the 1920s through 1960s ranch homes has separated at the joints from years of heat and hard use. The result is a duct system that leaks conditioned air and recirculates particles you don’t want in your living space. We repair the ductwork, reseal the connections, and then clean the entire path so the air moving through it is actually clean. Call (833) 734-6877 for a free estimate.
Why Altadena Homes Are Different
Altadena sits right against the San Gabriel foothills, which means two things for your ducts. First, the homes are predominantly single-story ranch and Spanish-style houses built between the 1920s and 1960s. Many of those original HVAC systems were never designed for modern filtration, and plenty of homes got flexible ductwork added years after construction. That flex duct is now old, sagging between supports, and separating at connections where the tape has dried out. Every separated joint pulls attic air and dust into the system. Second, the 2025 Eaton Fire deposited a fine layer of ash across the entire area. Technicians working in ZIP 91001 still find grey ash inside return plenums and on evaporator coils in homes well above Altadena Drive, even in houses that never showed visible smoke damage. Hot, dry summers push these systems to run hard, which keeps circulating whatever is trapped in the ducts. Add the ongoing rebuilds replacing fire losses, and you get a mix of older homes needing remediation and new construction that still benefits from a post-construction duct cleaning before move-in.

Our Main Altadena Services
Most homeowners reach out for one of two reasons: the ducts themselves are dirty or damaged, or the dryer vent is clogged and creating a fire risk. Here’s how we handle each one.
Air Duct Cleaning in Altadena
We clean the full duct path using professional Rotobrush and Nikro systems, the same contractor-grade equipment commercial HVAC crews use, not a shop-vac setup. In Altadena, that means removing not just everyday dust but the fine ash and char particles that settled into homes after the Eaton Fire. We access the supply and return plenums, agitate debris from the duct walls, and pull it into a HEPA-filtered collection system. Homes with children, pets, or anyone managing allergies or asthma notice the difference quickly. For a deeper look at how we approach the full job, see our Air Duct Cleaning in Altadena page.
Dryer Vent Cleaning in Altadena
Lint buildup inside a dryer vent is a leading cause of residential fires, and it’s a problem that develops quietly. Many Altadena homes have dryer vents that run long horizontal distances through attics or crawl spaces, which makes lint accumulate faster. We run professional brushes through the full vent run, remove the compacted lint, and confirm airflow at the exterior termination. This is a safety service, not an upsell. Read more on the dedicated Dryer Vent Cleaning in Altadena page.
Air Duct Repair in Altadena
Air Duct Repair in Altadena typically costs $200 – $650 per repair point, depending on access and how much duct needs replacing. Homes here need this service more than most because of the housing stock: flex duct from mid-century additions has dried out and separated, and the 2025 Eaton Fire accelerated deterioration with heat and ash exposure. A duct system with open joints pulls attic air, insulation fibers, and whatever settled in the attic into your living space. We find the compromised sections, repair or replace them, reseal every connection, and then clean the repaired path so you’re not fixing one problem and leaving another behind. This is the core of what we do, and you can read the full scope on our Air Duct Repair page.
HVAC Duct Installation
Signs you need it
Rooms that never reach the thermostat temperature, whistling or rattling from the vents, or visible kinks in exposed flex duct usually mean the existing layout is the problem.
What it costs in Altadena
New duct installation for a single run typically runs $300 – $800, while larger sections of the home range from $1,200 – $2,500.
How we do it
We plan the shortest straight path from the plenum to each register, hang the new duct with proper support spacing, seal every joint with mastic or metal tape, and test airflow before we finish.
Air Duct Replacement
Signs you need it
Duct insulation that is crumbling, visible mold or heavy char staining, or sections that have collapsed from age are all reasons to replace rather than patch.
What it costs in Altadena
Replacing a failed duct run typically costs $250 – $700, while whole-system replacement in an average Altadena ranch runs $1,500 – $3,000.
How we do it
We pull the old material, size the replacement to match the existing system’s airflow, install new insulated flex or rigid duct, and seal it at both ends.
Ductwork Repair
Signs you need it
Dust accumulating quickly on surfaces near vents, a sudden rise in your energy bill without a change in usage, or a room that stays hot all summer points to leaks.
What it costs in Altadena
Sealing leaky joints costs $150 – $400 per access point, while repairing a crushed or disconnected section runs $200 – $650 depending on location.
How we do it
We locate the leak with a visual inspection and airflow testing, reconnect or replace the affected section, and seal the repair with mastic so it stays tight.
What Air Duct Repair Costs in Altadena
| Item | Typical range in Altadena |
|---|---|
| Sealing leaky joints | $150 – $400 per access point |
| Repairing a disconnected or crushed section | $200 – $650 |
| Replacing a failed duct run | $250 – $700 |
Access makes a real difference in Altadena. Attics here get extremely hot in summer, and tight crawl spaces or long runs from mid-century additions can add labor time. Every estimate is free and the written quote is the price, agreed before work starts.
Can you repair ducts the same day you find a problem?
We can usually handle the repair on the same visit if the access is clear and the materials are on the truck. Most single-run repairs are done the same day.
Do Altadena homes need duct repair before cleaning?
If the ducts have open joints, cleaning alone won’t fix the air quality problem because attic dust keeps entering afterward. We repair first, then clean so the result holds. Call (833) 734-6877 and we’ll assess the whole system.
Brands We Service in Altadena
We work alongside filtration and air-quality products from Honeywell, Aprilaire, and Abatement Technologies. Parts for common residential setups are stocked on our trucks, so most brand-specific repairs don’t require a second trip. See our brands for the full list.

What Altadena Customers Say
"Two guys, about three hours, plastic down at every register, and they wiped the vent covers before putting them back."
- Roger Novak"Quoted per system rather than the bait and switch per vent pricing everybody else in town uses. The number I was told on the phone was the number on the invoice."
- Layla Najjar"Did the dryer vent while they were here for a small add on price. The dryer now finishes a load in one cycle instead of two."
