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 Glendora, CA
Air duct cleaning in Glendora runs between $450 and $1,100 for a full single-system home, and the job usually takes 3 to 5 hours. Glendora sits hard against the San Gabriel foothills, so the ducts here collect a mix most flatland cities never see: wildfire char, PM2.5 smog that stalls against the mountains, and fine granite dust that works into every seam. Older ranch homes with attic duct runs in 130°F heat make the work different, too. Call (469) 972-3151 for a written quote before anyone touches a vent.
Why Glendora Homes Are Different
Glendora’s housing stock is dominated by 1950s through 1970s ranch tracts where flex ductwork runs through unconditioned attics that routinely top 130°F in summer. That heat bakes duct liners, embrittles connections, and accelerates the buildup of particulate that would stay loose in a cooler home. In the lower city, pre-war and early postwar homes often had gravity furnaces converted to forced-air years ago, and those conversions left duct connections that pull foothill dust straight into the living space.
Then there’s the mountain factor. The San Gabriels directly north of Glendora act as a wall that traps the eastern San Gabriel Valley’s smog and ash, which is why SCAQMD monitoring consistently places this corridor among Southern California’s worst for PM2.5 accumulation. Fall Santa Ana winds drive coarse desert grit through any leaky seam. After the Colby Fire burned the hills above the city in January 2014, technicians working north-side neighborhoods pulled visible grey ash and char from duct systems across Glendora. That’s the recurring reality here: wildfire smoke finds its way into return plenums in ways flatland cities like Covina or West Covina, just a few miles south, don’t experience.
Our Main Glendora Services
Most Glendora homeowners call about two things: the ducts that carry heated and cooled air, and the dryer vent that carries lint. Each has its own Glendora page with full pricing and local detail.
Air Duct Cleaning in Glendora
We clean the full supply and return system in Glendora homes using negative-air extraction, which means a HEPA-filtered vacuum pulls loosened debris out of the ducts while a rotary brush agitates the duct walls with Abatement Technologies equipment. In foothill homes, we’re specifically looking for the grey post-fire char that settles in return plenums and the fine PM2.5 film that coats older flex runs. The full breakdown, including Glendora price ranges, is on the Air Duct Cleaning in Glendora page.
Dryer Vent Cleaning in Glendora
A clogged dryer vent in Glendora is a fire risk that gets worse with every load. We remove built-up lint by feeding a rotary brush through the full run from the dryer to the exterior termination, then confirm airflow at the outlet. Santa Ana season pushes extra grit into exterior vent hoods on foothill streets, so we check the termination point and the lint trap bypass every visit. Details and pricing are on the Dryer Vent Cleaning in Glendora page.

What Glendora Customers Say
"Our dryer was taking two cycles to dry a load. They cleaned the vent and pulled out a frightening amount of lint. Dries in one cycle now and honestly I feel better about the fire risk."
- Marcus Lee"Set up an appointment for the whole house plus the dryer line. They called the morning of to confirm, showed up in the window, and showed me pictures of the gunk they pulled out. Worth it."
- Terrence Boyd"My wife's allergies were awful every morning. Had the ducts done and it's made a real difference. Tech was on time and wore booties in the house without me asking."
