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 Walnut, CA
Air duct cleaning in Walnut, CA doesn’t work the way it does in coastal Los Angeles. Our crews pull heavily contaminated air through duct systems built into 30-to-50-year-old tract homes, where original flex duct has spent decades baking in attics that hit 150°F in summer. The result is faster fouling, more particulate buildup, and a bigger difference after a proper cleaning than most homeowners expect. If you’re looking for an air duct cleaning company in Walnut, call (980) 447-2498 and we’ll walk you through what your system likely needs and what it’ll cost.
Why Walnut Homes Are Different
Walnut sits at the eastern terminus of the San Gabriel Valley smog corridor. Prevailing westerly winds push basin-wide ozone and fine particulates against the San Jose Hills and surrounding ridgelines, and SCAQMD monitoring consistently records some of the highest PM2.5 and ozone readings in Southern California right here. That means the air entering your return registers is already carrying a heavier particulate load than what homeowners in, say, Pasadena or Long Beach are breathing.
Then there’s the housing stock. Walnut developed almost entirely as a planned suburb between the mid-1970s and early 1990s, which leaves most homes with original or first-generation flexible duct systems. These fiberglass flex ducts sag at low points, separate at plenum connections, and shed deteriorating outer insulation jackets. When the blower kicks on, that compromised duct network pulls attic air and trapped debris straight into the supply stream. Clean the coils and filters all you want; if the ducts themselves are cracked, separated, and lined with years of accumulated particulate, the system is still recirculating contaminated air through every room.
June through October is the hardest stretch. Temperature inversions trap ground-level pollution in the Pomona Valley basin, and Santa Ana events reverse the pattern entirely, funneling wildfire smoke and ash from the Inland Empire directly into Walnut. What lands in your ducts during those acute spikes stays there until someone removes it.
Our Main Walnut Services
Most Walnut homeowners call us for one of three things: a full air duct cleaning, a dryer vent cleaning, or a repair on a duct system that’s showing its age. Here’s what each job actually involves in Walnut.
Air Duct Cleaning in Walnut
We run professional-grade negative-pressure extraction through the entire supply and return network, pulling the accumulated dust, fiberglass particles, and smoke residue that Walnut’s air quality loads into your ducts. In these 1970s and 80s tracts, we routinely encounter partial collapses and inner-liner cracking from decades of attic heat, so the cleaning almost always doubles as a condition inspection. When we find a problem, we show you photos and quote the repair separately before any work continues. Full details on our process, what’s included, and how long it takes are on the Air Duct Cleaning in Walnut page.
Dryer Vent Cleaning in Walnut
Dryer vents in Walnut homes often run long, angled routes from a laundry room through the attic or out a second-story wall. Lint builds up at every bend, and by the time you notice longer dry times, the vent is already restricted enough to be a fire risk. We use a lint trap bypass method that captures debris at the wall, then run rotary brushes the full length of the vent to remove compacted lint. You’ll find specifics on how we handle long runs and what a typical cleaning costs on the Dryer Vent Cleaning in Walnut page.
Air Duct Repair in Walnut
Flex duct doesn’t last forever in Walnut attics. We regularly find separated plenum connections, sagging runs, and crushed sections that homeowners never see because the damage sits behind attic access panels. A torn outer jacket or separated seam lets unfiltered attic air enter the supply stream, which is the same air that’s been sitting in a 150°F attic all day. Our repair work includes written pricing before we start and a written guarantee on every job. See what we repair, how we inspect, and how the guarantee works on the Air Duct Repair in Walnut page.

In Walnut, what pushes price up is usually the age of the home. 1970s and 80s tract houses often have longer-than-average duct runs, attic access that slows the work, and flex duct that’s degraded to the point where more replacement sections are needed than a newer home would require. Whatever the number ends up being, it’s put in writing before any work begins. No surprise invoices, no “we found something while we were in there” escalation.
