Air Duct Cleaning Company in Montclair, CA
Air Duct Repair in Montclair is the call we get when a mid-century tract home’s galvanized metal ducts finally give out. Homes along Kingsley Street and Ramona Avenue, many built between 1955 and 1975, still run the original sheet-metal returns. Decades of valley heat, freeway dust, and attic temperature swings leave that ductwork cracked, disconnected, or collapsed at the seams. We repair it, and we clean what’s left. If you’re looking for the full picture on what your ducts need, call us at (877) 265-9115.
Why Montclair Homes Are Different
Montclair sits in the Pomona Valley, where summers routinely push past 95°F and the AC runs from June through October. That continuous load pulls attic insulation fibers and decades of accumulated dust through return ducts, baking fine debris onto the galvanized steel interiors. The tract homes north of the 10 freeway, especially the single-story builds from the 1960s, often have the furnace in a hallway closet with original metal returns that collect a fine gray film from valley wind and freeway traffic. When we open those ducts, we’re looking at years of hot-side accumulation, not just surface dust from pets. In the newer stucco infill near Montclair Place, the problems shift to flexible duct runs that sag, kink, or separate at the collar. The house changes the job, and we carry equipment for both.

Our Main Montclair Services
Montclair homeowners call Timberline most often for two things: cleaning the ducts that haven’t been touched since the house was built, and clearing dryer vents that pose a real fire risk in these tight mid-century laundry closets. Here’s what each involves here.
Air Duct Cleaning in Montclair
Duct cleaning in Montclair means removing the gray, baked-on film that forms inside original metal returns and supply lines. We run our Rotobrush rotary brush system through every accessible trunk line and branch, while the Abatement Technologies negative-air setup keeps dislodged debris from blowing back into your living room. Homes near the 10 freeway pick up more fine particulate than most people realize, and it concentrates in the return duct feeding a hallway closet furnace. This isn’t a surface wipe – it’s a removal process for what decades of Pomona Valley air left behind. Full details on our Montclair process and pricing are on Air Duct Cleaning in Montclair.

Dryer Vent Cleaning in Montclair
Your dryer vent is a fire risk. We treat it that way. In Montclair’s older single-story homes, dryer vents often run through the slab or out a short wall termination that’s rarely visible from the outside, which means lint builds up for years without anyone noticing. We clean the full vent run with professional equipment, not a drill attachment, and we’ll tell you if the original metal duct has rusted through and needs replacement. For the full scope of what we do in Montclair dryer vents, visit Dryer Vent Cleaning in Montclair.

Air Duct Repair in Montclair
In Montclair, air duct repair is usually about original 1960s metal ductwork that has outlived its useful life. The combination of shallow attics, slab foundations, and decades of 100-degree summer afternoons leaves galvanized ducts separated at joints, crushed by storage, or rusted along the bottom seam from condensation cycles. When your return air leaks from a hole in the attic duct, your system pulls in whatever is up there, and your AC works harder trying to condition air it never recovers. Timberline Air Duct Cleaning handles repair as a core service, not an afterthought, because the full answer to bad air and weak airflow is in the ducts themselves, not just the cleaning. For a broader look at how we approach repairs, see Air Duct Repair.
Ductwork Repair
Signs you need it
Rooms that never reach the same temperature as the rest of the house, visible dust around return grilles, or a furnace that runs constantly without satisfying the thermostat all point to air escaping through failed duct joints or holes.
What it costs in Montclair
Ductwork repair in Montclair typically ranges from $180 to $640 depending on how many joints and seams need sealing and reinforcement.
How we do it
We locate the failed section with a visual inspection and airflow testing, then re-secure separated joints, apply mastic and foil-backed tape at seams, and patch holes with galvanized metal before re-testing airflow at the register.
Duct Replacement
Signs you need it
Ducts that have collapsed under the weight of attic storage, rusted through along the bottom seam, or torn at the takeoff collar are beyond repair and need replacement.
What it costs in Montclair
Replacing a damaged run of rigid metal duct in a Montclair attic typically falls between $700 and $2,000, and flexible duct replacement ranges from $400 to $1,500 per run.
How we do it
We remove the failed section, inspect the remaining duct for hidden damage, install new sheet-metal or flexible duct sized to match your system, seal every connection with mastic, and check static pressure to confirm the system is balanced.
What Air Duct Repair Costs in Montclair
| Item | Typical range in Montclair |
|---|---|
| Ductwork repair (sealing joints, patching holes) | $180 – $640 |
| Duct replacement (per run of rigid metal) | $700 – $2,000 |
| Duct replacement (per run of flexible duct) | $400 – $1,500 |
Two things push cost up in Montclair: shallow attics that make access physically harder, and homes where the original ducts were undersized from the start and need a section re-engineered rather than just swapped. Whatever we quote, it is one flat price per project agreed before work begins.
How long does duct repair take in a Montclair home?
Most single-run duct repairs in Montclair take between 2 and 5 hours on site. Attic access in these mid-century homes is usually tight, so the job depends on how much room we have to work and how many register boots need re-sealing. We’ll give you a straight time estimate before we start.
Can you fix ducts that were installed with the original 1960s house?
Yes, and that’s most of what we do in Montclair. We repair and reconnect original galvanized ductwork where it’s still sound, and replace sections that have rusted or separated beyond repair. You don’t have to yank out an entire system if the majority is still holding air.
Brands We Service in Montclair
We work with Honeywell and Aprilaire air-quality products in Montclair homes, from media cabinets to whole-home filtration upgrades that pair with the ductwork we service. We also know Abatement Technologies equipment inside out, since that’s what we run for contained cleaning on every job. See our brands for the full list.

What Montclair Customers Say
"Found a disconnected run in the crawlspace while they were in there and told me about it rather than cleaning around it."
- Eduardo Reyes"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."
- Diego Hernandez"Told me straight that our ducts were in decent shape and didn't need doing every year like the mailer companies claim."
