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 Gabriel, CA
Air duct cleaning in San Gabriel runs between $350 and $650 for most homes, depending on system size and how much debris has settled inside. This is one of the most particulate-heavy air basins in the country, so ducts here load up faster than they would three miles closer to the coast. If your filters darken in weeks instead of months, that’s the San Gabriel Valley at work, not your imagination. Call (469) 972-3151 and we’ll tell you exactly what it’ll cost before anyone touches a vent.
Why San Gabriel Homes Are Different
San Gabriel sits at the floor of a bowl. The San Gabriel Mountains rise a few miles north and trap whatever the basin produces: smog, brake dust, fine particulate from the 10 and 710 corridors, and in autumn, Santa Ana winds that push Mojave Desert dust straight through the passes and into the valley. The South Coast Air Quality Management District consistently ranks this basin among the worst in the nation for PM2.5, and that ranking shows up inside ductwork. Homes here accumulate contaminant loads that would take years to build in a coastal community with steady air exchange.
The housing stock makes it worse. Most of San Gabriel’s residential core is post-WWII tract housing from the late 1940s through the mid-1960s, much of it still running original sheet-metal ducts. Around the San Gabriel Mission District, you’ll find 1920s and 1930s bungalows where central forced-air was added decades after the home was built. Those retrofit jobs often repurposed the old gravity-furnace plenum as a return chase with no filter rack installed, which means decades of unfiltered valley air deposited directly onto duct walls. It’s a configuration that surprises technicians used to newer construction, but it’s common here.
Wildfire smoke adds another layer. The Angeles National Forest starts just a few miles north, and when it burns, fine ash and combustion residue settle across San Gabriel and get pulled into return registers. That residue is fine enough to pass through a standard 1-inch filter, then it adheres to duct walls and blower assemblies. Homes at the base of this mountain range experience this repeatedly; it’s not a one-off event.
What all this means for cleaning: we expect heavier debris loads, older duct interiors, and filter slots that may have been added as an afterthought. We plan for those conditions before the first register is opened. That’s why Dale Whitmore insists on walking the system with the homeowner before cleaning starts, so what we quote is what the job actually involves.
Our Main San Gabriel Services
San Gabriel homeowners call us about two things: the ducts that move heated and cooled air through the house, and the dryer vent that exhausts lint and moisture outside. Each service has its own dedicated San Gabriel page with full pricing and details.
Air Duct Cleaning in San Gabriel
Our Air Duct Cleaning in San Gabriel page covers the full process: brush agitation to dislodge debris from duct walls, negative-air extraction to pull it out of the system, and HEPA filtration to keep loosened particles out of your living space. San Gabriel’s older sheet-metal ducts and Mission District retrofit systems respond well to this approach, but the debris load is often heavier than what crews see in newer coastal builds. You’ll see before-and-after photos of your own ducts, not stock images.
Dryer Vent Cleaning in San Gabriel
Clogged dryer vents are a genuine fire risk, and in San Gabriel they fill faster than average because lint mixes with the same fine particulate that settles everywhere else in this basin. Our Dryer Vent Cleaning in San Gabriel page explains how we clear the full run from dryer to exterior termination point, including lint trap bypass and the vent cap. If your clothes take two cycles to dry, the vent is telling you something. We’d rather clean it before it becomes a hazard.

What San Gabriel Customers Say
"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."
- Rob Pendergast"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."
