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.

AfterAir Duct Cleaning Company in Duarte, CA
Air duct cleaning in Duarte typically costs $395 – $890 for a whole-home system, depending on home size and how much wildfire ash and mountain dust the ducts have absorbed. Duarte sits directly at the base of the San Gabriel Mountains, which means your ductwork works harder than systems ten miles west. We’re Linden Air Duct Cleaning, and we’ve been doing this work since 2004 as part of the Threshold Group family. Call (980) 447-2498 for a written quote before any work begins.
Why Duarte Homes Are Different
Duarte’s residential core is dominated by post-WWII ranch-style tract homes built between the 1950s and 1970s. Those homes have a specific anatomy: long, low rooflines with attic spaces that bake in the San Gabriel Valley sun, and metal ductwork that is now 40 – 60+ years old. Over decades, that ductwork has been patched with flex duct at the joints, and those joints separate. When a joint opens in a hot Duarte attic, the system pulls in whatever is in that attic: fiberglass particles, dust, and fine ash from the mountains.
The 2020 Bobcat Fire changed what Duarte homeowners find inside their ducts. The fire burned 115,000+ acres in the San Gabriel Mountains immediately above the city, and for weeks the smoke sat in the valley. Technicians working the Duarte/Monrovia corridor after that fire found fine char particles inside ducts even in homes where residents kept windows shut the entire time. The cause was simple: negative pressure from air handlers pulled contaminated air through leaky duct joints in attics exposed to exterior smoke infiltration. That’s not something you fix with a filter change. That’s duct cleaning, and sometimes duct repair.
Santa Ana winds also funnel coarse particulates directly off the mountain front and into Duarte’s residential valley floor. Homes in the northern neighborhoods, closer to the foothills, get the worst of it. Duarte is also home to the City of Hope National Medical Center, and many households here include patients, survivors, or immunocompromised family members for whom indoor air quality is not a preference. It’s a medical reality.
Our Main Duarte Services
Duarte homeowners call us most about two things: cleaning ducts that have accumulated decades of dust and wildfire particulate, and repairing the aging ductwork that lets contaminated attic air back in. Each service has its own Duarte page with full pricing and details.
Air Duct Cleaning in Duarte
Cleaning ducts in a 1950s – 1970s Duarte ranch home means more than running a vacuum through the vents. We use negative-pressure extraction to pull loosened debris out of the system under suction, so it doesn’t recirculate into your living space. Duarte attics hold decades of dust, and after the Bobcat Fire, many hold fine ash too. We also treat for the specific problem of aging metal ductwork with deteriorating flex-duct patches, which shed fibers as they break down. See Air Duct Cleaning in Duarte for full pricing and what the job includes.
Dryer Vent Cleaning in Duarte
Dryer vents in older Duarte ranch homes often run long horizontal distances from the laundry room to the exterior wall, sometimes with multiple elbows. That design catches lint fast. We work with homes where dryer vents run through the slab or attic, and we check for a common Duarte problem: vents that terminate under eaves where Santa Ana winds push debris back into the opening. A clogged dryer vent is a fire hazard, and we treat it that way. Full details on Dryer Vent Cleaning in Duarte.
Air Duct Repair in Duarte
Older Duarte homes often have duct joints that have separated over decades of heat cycling in the attic. When a joint opens, your system pulls attic air, and in Duarte that can mean ash, insulation dust, and mountain particulate entering your airstream. We repair separated joints, replace broken-down flex duct runs, and seal the system so it holds negative pressure the way it should. Every repair is covered by a written guarantee, and if a repair fails we return at no charge. Details on Air Duct Repair in Duarte.

What Duarte Customers Say
"Thorough job on all eleven vents and the main trunk. Took longer than the three hours they quoted, but he told me early and kept working. Air feels fresher."
- Meredith L."Tech arrived with a badge and a printed sheet of what he'd be doing. Ran a camera through the main trunk before and after so I could see the dust difference. Vents smell cleaner already."
- Gina R."Priced by the system, not by the vent, and he told me up front. No pressure to add the sanitizer and I said no without any fuss."
- Faith N.
