Whole-system duct and dryer vent check with before-and-after photos - you see exactly what came out of your vents
That "$99 whole-house special" is a bait ad - the real number appears once they are in your hallway, or the "clean" is a shop-vac at the register. We photograph the inside of your ducts before and after instead.
Fast, Reliable Air Duct Repair Across Montclair
Air duct repair in Montclair usually runs between $280 and $1,600 depending on what’s actually wrong. A disconnected sheet-metal joint in a 1960s tract house attic costs far less than replacing a collapsed flex-duct run that’s been baking at 140°F for two decades. If you’re noticing dust accumulating on furniture within days of cleaning, rooms that never reach the temperature you set, or a musty smell when the blower kicks on, the problem is probably in your ductwork, not your furnace.
We’ve worked the neighborhoods around Central Avenue, the Monterey Avenue corridor, and the older blocks near Kingsley Street long enough to know exactly what Montclair’s housing stock throws at us. Our Air Duct Repair team serves the whole city, from the 91763 zip code to the newer developments west of Ramona Avenue. Call (980) 447-2498 and we’ll give you a straight answer about what’s happening in your ducts and what it costs to fix.
Why Linden Air Duct Cleaning Is Montclair’s Preferred Air Duct Repair Company
Montclair homeowners have a specific set of worries when they let a technician into the house. We understand that. You’re often home alone, or you’ve got young kids napping upstairs, or you’re simply not comfortable with a stranger walking your hallway. So we built our entire process around answering the question you actually care about: who is this person, and what will they do once they’re inside?
Every technician we send to a Montclair home is background-checked and identity-verified under the Threshold Standard. Before the visit, you receive the tech’s name and photo. At the door, they show a photo ID badge. No exceptions. Marcus Veale oversees this process personally because he knows that in a city like Montclair, where homes are close together and neighbors talk, trust is earned door by door.
We’ve been doing this since 2004 as part of the Threshold Group family. That’s twenty-plus years of walking into strangers’ homes and proving we belong there. Montclair customers call us back because the price we quote is the price they pay. Always in writing before work begins. Always.
HVAC Duct Installation in Montclair
HVAC Duct Installation in Montclair means something specific here: running new duct through unconditioned attic spaces that regularly hit 140°F in July and August. That heat is the reason we prefer insulated flex duct with a high-temp liner rating over cheap uninsulated runs, and why we recommend sealing every joint with mastic rather than relying on tape that fails after two Inland Empire summers.
A full HVAC duct installation for a typical 1,200 to 1,800 square foot Montclair tract house generally runs $3,800 to $7,200 depending on access, the number of runs, and whether the air handler needs to be repositioned. Add $400 to $900 if we need to enlarge return-air capacity, which is common in post-war homes that were designed for smaller, less efficient systems.
When Installation Beats Repair
If your ducts are original 1950s-1970s sheet metal and a camera inspection shows multiple failed joints, sections of collapsed liner, or asbestos tape that’s crumbling, repair stops making sense. Patching five failed joints on a 60-year-old system costs nearly as much as installing new duct in a slab-on-grade home where the runs are short and accessible.
The Montclair Attic Factor
Homes east of Central Avenue tend to have shallower attic pitches than the newer construction near the 10 freeway. That means less working room, which means installation takes longer and costs more. We factor that into our quote up front, not after we’ve cut a hole in your ceiling.
Air Duct Replacement in Montclair
Air Duct Replacement in Montclair is often the better call than repair when we’re dealing with the 40-to-70-year-old sheet-metal systems that make up most of the city’s residential stock. The failure mode is consistent: joint separation where the duct meets the boot, interior liner breakdown from decades of 100°F+ heat cycling, and gaps that pull attic insulation dust into the return side every time the air handler cycles.
Replacing a single failed run of duct in a Montclair home typically costs $450 to $1,200. Replacing the entire duct system, including supply plenum, return drops, and all flex runs, runs $4,000 to $8,500 for an average tract home. The high end covers homes where ducts run through tight attic spaces or where the original design undersized the return air, which we see constantly in 1960s builds.
Signs Your Montclair Ducts Need Replacement
Rooms at the end of the longest duct runs stay warm in summer no matter how low you set the thermostat. Dust returns to window sills within three days of cleaning. The air handler cycles off and on more often than it should. In Montclair’s particulate-heavy air, these symptoms show up faster than in coastal cities because the ducts are working harder against dirtier air.
What Replacement Includes
Every replacement includes sealing the boots, reconnecting and balancing runs, setting blower motor amp draw to manufacturer spec, and a camera inspection afterward so you can see the work. You get before-and-after photos of your own ducts. Not stock images. Yours.
Trusted Brands We Service in Montclair
We work on whatever’s in your attic, whether it’s original 1960s sheet metal, a mid-era retrofit with cheap flex, or a newer system with properly sealed runs. We carry Rotobrush and Nikro equipment for cleaning and agitation, and we stock air-quality products from Abatement Technologies and Guardsman for post-repair filtration upgrades.

Your repair gets done the day we arrive.
Common Air Duct Repair Problems We See in Montclair Homes
- Diesel-soot film on duct interiors. Homes east of Central Avenue sit close enough to the Ontario logistics corridor that supply and return ducts build a grayish-brown particulate film that’s thicker and greasier than household dust. It takes extra agitation passes to break up, and it returns faster than in Claremont or La Verne, so cleaning intervals here are shorter.
- Attic duct liner delamination. Montclair attics hit 140°F+ for weeks at a stretch. Original flex-duct liners from the 1970s and 1980s delaminate in that heat, and pieces of liner end up blowing through supply registers into living spaces. If you see grayish flakes around your supply vents, that’s liner material, not dust.
- Sheet-metal joint separation. Post-war tract homes were built fast, and duct joints were often just slip-fit and taped. Sixty years of thermal expansion and contraction separates those joints, and the gaps pull attic dust and insulation fibers into the return side. This is the single most common repair we do in Montclair.
- Santa Ana re-contamination. Between October and March, Santa Ana winds push desert dust and PM2.5 directly into return-air intakes. Ducts that were cleaned in September can be heavily loaded again by Thanksgiving, especially if the home has a low-MERV filter that lets fine particulate through.
Pricing for Air Duct Repair in Montclair, CA
Air duct repair in Montclair runs $280 to $1,600 for most jobs. A simple sheet-metal joint reseal at the boot costs $280 to $450. Replacing a failed flex run runs $450 to $1,200 depending on access and length. Full system replacement runs $4,000 to $8,500. Those are real ranges, not teaser numbers.

FAQs About Air Duct Repair in Montclair
Every 3 to 5 years, and closer to 3 if you live east of Central Avenue or within a mile of the 10 freeway freight corridor. Montclair’s position at the eastern end of the LA air basin means westerly winds stack smog and Ontario diesel soot against the San Gabriel foothills, and that particulate ends up in your return air. Homes in Claremont can stretch to 5 or 6 years. Montclair homes with original 1960s ductwork should be inspected at least once a year. Call (980) 447-2498 and we’ll tell you honestly whether your ducts need work now or can wait.
Yes. We service all of Montclair, including the neighborhoods east of Central Avenue where duct interiors build that grayish-brown diesel-particulate film. That film doesn’t come off with a standard brush pass. Our crews run extended agitation with Rotobrush and Nikro equipment, which adds time to the job but actually removes the contaminant instead of polishing it. The price reflects the extra labor, and we explain that up front.
If the camera inspection shows one or two separated joints and the metal itself is sound, repair makes sense at $280 to $450 per joint. If the liner is delaminating, the boots are rusted through, or you’ve got multiple failures, replacement is the honest recommendation. Replacing the system in a typical Montclair tract house runs $4,000 to $8,500. We’ll show you the camera footage before you decide. Call (980) 447-2498 for an inspection.
We service and repair ductwork from every major manufacturer and the original sheet-metal systems still common in Montclair’s 1950s-1970s housing stock. Our trucks carry Rotobrush and Nikro equipment for cleaning and agitation, and we stock Guardsman and Abatement Technologies products for air-quality upgrades after repair. If your system is older, we’ll tell you straight whether replacement parts are still available or whether you’re better off replacing the run.
Yes. Attic temperatures in Montclair regularly exceed 140°F in summer, which accelerates liner breakdown and joint separation. Ductwork that might last 25 years in a coastal climate can fail in 15 to 20 here. If your ducts are already 40-plus years old and you’re seeing liner flakes at the supply registers or dust return within days of cleaning, replacement is worth doing before the next summer peak, not after. Call (980) 447-2498 and we’ll give you a written quote.
