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 Diamond Bar, CA
Air duct cleaning in Diamond Bar means something different than it does ten miles west. Homes here collect freeway particulate faster, attics bake ductwork harder, and whole neighborhoods share the same aging original systems. That’s the short version. Morton’s Air Duct Cleaning handles both air duct cleaning and dryer vent cleaning for this city, with a written price before any work starts and a 365-Day Done Right Promise on every job. Call (323) 918-4345 to talk it through. Our full home page covers the broader picture.
Why Diamond Bar Homes Are Different
Diamond Bar sits at the junction of the 57 and 60 freeways, two of the busiest diesel freight corridors in Southern California. The city’s bowl-shaped valley geography then traps what those trucks leave behind against the San Jose Hills. What ends up in return ducts here isn’t ordinary household dust. It’s fine diesel soot, tire rubber particles, and brake dust, and it settles in at a rate that surprises even long-time residents. A return vent that looks normal in a Chino Hills home may be coated gray-black in Diamond Bar after the same number of months.
The housing stock adds another layer. Diamond Bar was developed as a Transamerica Corporation master-planned community, most of it built between the late 1960s and the late 1980s. Large contiguous tracts share the same construction vintage and nearly identical original ductwork, usually fiberglass duct board or early flex duct now 35 to 55 years old. Attics here reach extreme summer temperatures, which accelerates insulation breakdown and joint separation. Because whole subdivisions went up in the same two- or three-year windows with the same materials, our technicians regularly find that when one home’s original duct board has crumbled, the neighbors two doors down are weeks away from the same failure. It’s one of the few places we work where neighborhood-level patterns hold this consistently.
Our Main Diamond Bar Services
Here are the two services Diamond Bar homeowners call us about most. Both come with a written price before work begins, shoe covers and drop cloths inside, and a photo of the clean-up before the crew leaves.
Air Duct Cleaning in Diamond Bar
Full-system air duct cleaning here has to account for what Diamond Bar specifically puts into ductwork: heavy freeway particulate loading on return systems and attic heat that’s compromised older flex duct and duct board in many of the city’s original homes. Our crews run professional-grade equipment from Rotobrush and Nikro, not rental gear, and we walk the system with you before anyone touches a register. If you’re noticing dust return quickly after cleaning, or rooms that never seem to hold temperature, this is the page to read: Air Duct Cleaning in Diamond Bar.
Dryer Vent Cleaning in Diamond Bar
Dryer vents in Diamond Bar face two compounding pressures: lint from daily family loads, and the same particulate air that affects ducts. A vent that exits through an attic or a second-story wall in one of the city’s hillside homes is working against longer runs and tighter bends than a single-story layout. We clean the full run from dryer to exterior termination, check the vent cap, and verify airflow before we pack up. You can find the full scope here: Dryer Vent Cleaning in Diamond Bar.

Most Diamond Bar jobs are scheduled within one to two business days. We coordinate dispatch from our Los Angeles-area office and plan routes so our Diamond Bar appointments cluster on the same day, which helps keep scheduling straightforward.
For interior work like duct cleaning or dryer vent cleaning, no. The work happens inside your home and at your exterior vent termination, which is your own unit’s responsibility. If a roof or wall repair were ever needed as a separate follow-up, that’s when HOA coordination might apply.
Yes. A large share of Diamond Bar’s housing stock is two-story or built into hillside lots, and our equipment and process handle both.

What Diamond Bar Customers Say
"Friendly, calm crew that clearly cared about the house. Covered their shoes, protected the floors, and double checked they'd closed up every vent cover properly. Would have them back."
- Omar Zaid"Ducts and dryer vent both. They put runners down the whole hall and wore booties. Spotless after, and they showed me photos of what came out. Worth every penny."
- Bonnie Vo"Spotless work. They laid drop cloths everywhere and I was honestly impressed there was zero mess at the end. Showed me the dirt they pulled out so I could see it was worth it."
