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 costs between $350 and $750 for a full home in most cases, depending on the size of the system and how long it’s been since the last cleaning. Walnut homes present a specific challenge: many were built between the late 1960s and early 1990s, meaning their original flex-duct and fiberglass duct-board systems are now 35 to 55 years old. We’re Morton’s Air Duct Cleaning, and we walk you through the written price before any work starts. Call (323) 918-4345 for a free estimate.
Why Walnut Homes Are Different
Walnut sits at the eastern pinch-point of the San Gabriel Valley basin, hemmed in by the San Jose Hills. That geography traps ozone and fine particulate matter at concentrations that rank among the highest in Los Angeles County. HVAC systems here pull in far more PM2.5, smog byproducts, and wildfire smoke residue than those in coastal communities. Add the steady industrial dust blowing in from the nearby City of Industry and the Pomona Valley wind corridor, and you get duct interiors that load up faster and dirtier than almost anywhere else in the region.
The housing stock makes matters worse. Walnut was built out primarily as a planned suburban community between the late 1960s and the early 1990s, which leaves a large share of homes running original flex-duct or fiberglass duct-board systems now past the 35-year mark. Those interior liners deteriorate and shed fibers into the airflow. In the northern hillside areas, homes built in the 1980s and 1990s along the San Jose Hills grading often have long duct runs through super-heated attic spaces, which accelerates that liner breakdown. Technicians working these hillside homes consistently find cracked liners shedding fiberglass into the plenum, especially in attics facing south or west, where summer temperatures regularly exceed 100°F. The combination of attic heat and late-1970s installs makes northern Walnut a consistent source of the most severe duct-liner deterioration calls in the eastern San Gabriel Valley.
Our Main Walnut Services
These are the two jobs Walnut homeowners call us about most often, and each has its own detailed page with local pricing and specifics.
Air Duct Cleaning in Walnut
Air duct cleaning in Walnut means contending with the fine particulate load that this valley position concentrates. The ozone and industrial dust that settle into local ductwork don’t come out with a basic brush; our crews use Rotobrush and Nikro equipment to break the buildup loose and extract it. In the older flex-duct systems common across Walnut, we pay close attention to liner condition, because aging fiberglass interiors shed fibers that then circulate through the house. You’ll see the written price before we begin, and we photograph the clean-up before we leave. See Air Duct Cleaning in Walnut for full details and pricing.
Dryer Vent Cleaning in Walnut
Dryer vent cleaning in Walnut is a quiet but critical job, especially in the hillside homes where dryer runs extend through super-heated attic spaces. Lint builds faster when ambient dust is high, and Walnut’s air carries more of that dust than coastal LA. A clogged vent forces the dryer to work harder and creates a fire risk. Our technicians clear the full vent run and leave the laundry area cleaner than they found it, with shoe covers on from the moment they step inside. Read more at Dryer Vent Cleaning in Walnut.
