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 San Dimas, CA
Air duct cleaning in San Dimas costs between $329 and $589 for most single-system homes, with larger two-story properties running $589 to $989. The foothill location changes the job in ways a coastal crew would miss. Homes here pull in mountain ash, canyon dust, and Pomona Valley particulate at a rate that leaves duct interiors visibly coated within a year or two of a cleaning. If you’re seeing dust settle back onto furniture days after wiping it down, call (469) 972-3151 and we’ll tell you exactly what a San Dimas job involves and what it costs before we ever schedule the visit.
Why San Dimas Homes Are Different
San Dimas sits at the base of the Angeles National Forest, and that geography drives how fast ducts foul here. After any significant fire in the San Gabriel Mountains above town, downslope drainage winds push smoke and fine ash directly into attic and soffit return air intakes on north-facing homes. Technicians find visible char coating past the filter in return air plenums before the smell even registers indoors. That wildfire exposure compounds with the South Coast Air Basin’s particulate trapping: mountains on three sides stall pollutants while Santa Ana winds funnel desert dust from the canyons onto valley floor homes. Summer temperatures routinely cross 100°F, which means near continuous AC cycling and a steady pull of outdoor particulate through return ducts.
The housing stock adds another layer. Most residential tracts around San Dimas Avenue, Bonita Avenue, and east of downtown were built between the 1960s and early 1980s. A large share still run original fiberglass flex duct and early sheet metal systems, often with decades of compacted debris baked onto duct walls. The older Victorian era homes near the historic downtown core add another wrinkle: many were retrofitted with ductwork in non standard configurations that require a more careful inspection before cleaning begins.
Our Main San Dimas Services
Two services account for nearly every call we take from San Dimas homeowners. Each has its own dedicated page with full pricing and job details.
Air Duct Cleaning in San Dimas
Whole-system air duct cleaning is the core San Dimas job, and it runs deeper here than in most LA basin communities. We use negative air extraction, which means a Nikro vacuum unit pulls the system under negative pressure while a Rotobrush rotary brush agitates debris off the duct walls, so loosened material is captured rather than pushed into living space. Homes near the foothill edge regularly show fine ash and char particulate in return plenums that never reached the filter. Full details and San Dimas pricing are on the Air Duct Cleaning in San Dimas page.
Dryer Vent Cleaning in San Dimas
Dryer vents in San Dimas clog faster than homeowners expect, partly because lint combines with the same fine canyon dust that loads the rest of the system. A lint trap bypass is part of our standard inspection: we check whether any air is slipping around the trap itself, which lets lint pack the vent run even when the trap looks clean. Foothill homes with longer vent runs to exterior walls are the most common call. See the Dryer Vent Cleaning in San Dimas page for what the job includes and what it costs here.

Pricing for Air Duct Cleaning Company in San Dimas, CA
| Service | Typical range in San Dimas |
|---|---|
| Air duct cleaning – single system (up to 10 vents) | $329 – $589 |
| Air duct cleaning – two-story home or systems over 10 vents | $589 – $989 |
Two things push San Dimas prices toward the upper end of those ranges: decades of compacted debris in 1960s to 1980s era systems that were never cleaned, and heavier than typical ash and fine particulate coating from wildfire smoke and Santa Ana dust events. Regardless of where your job lands, the written price is in your hands before any work begins. That is the Kingswell Guarantee, and it does not change at the door.

What San Dimas Customers Say
"Bought an older home and the previous owners had pets everywhere. After Kestrel did the ducts the stale smell was just gone. On time, quick, and they showed me the filter they pulled."
- Preston Ngata"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."
