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 typically costs $350 – $650 for a whole-home system and is scheduled by appointment with a written price locked in before work begins. Walnut’s mix of aging 1980s – 1990s tract homes, dry Santa Ana winds, and heavy summer cooling loads creates duct conditions we don’t see in newer coastal markets. We serve Walnut from our Los Angeles scheduling office, with local crews who know the flex-duct layouts in Walnut Valley, Timberline, and the older Snow Creek builds. Call (361) 326-5060 for a free estimate.
Why Walnut Homes Are Different
Most houses here are two-story Mediterranean or contemporary tract homes built from the late 1970s through the 1990s, and that age matters for ductwork. Original flexible duct runs in attics and between floors are now 25 – 35 years old, old enough to sag, tear at connections, or get crushed by decades of attic traffic. In Walnut Valley and Timberline, we regularly find flex ducts that have disconnected at attic takeoffs, blowing conditioned air into the insulation instead of the bedroom.
The climate pushes these systems hard. Walnut runs cooling six to seven months a year, and those long run times pull dust and allergens through return ducts continuously. Fall Santa Ana winds add another layer, carrying fine dust and debris through outdoor intakes and attic vents. Near the 57 and 60 freeways, construction activity has sent concrete and asphalt particulates into outdoor HVAC units for years, and that material migrates into ductwork. We’ve cleaned systems in Creekside where the return trunk was lined with a fine gray film that didn’t match ordinary household dust. Walnut’s terrain also matters, homes climbing the foothills toward Diamond Bar catch more wind exposure, and attic access can be tight on hillside lots where builders tucked mechanicals into smaller spaces.
Our Main Walnut Services
Walnut homeowners call us most often for three jobs, each with its own page and pricing.
Air Duct Cleaning in Walnut
We clean supply and return ducts with a rotary brush system that agitates debris off duct walls, paired with negative-air suction to pull it out of the house, not redistribute it. In Walnut’s older two-story homes, we pay special attention to second-floor flex runs in chase walls, where sagging creates low spots that collect dust. We finish with a written before-and-after photo report. Air Duct Cleaning in Walnut covers full pricing and what’s included.
Dryer Vent Cleaning in Walnut
Dryer vent blockages are a genuine fire hazard, and Walnut’s lint buildup is often worse than coastal cities because dry air lets static cling hold more debris to duct walls. We run a rotary brush and high-velocity vacuum through the full vent line to the exterior cap, then measure airflow to confirm restoration. If your dryer takes two cycles or the laundry room heats up, the vent is likely restricted. Dryer Vent Cleaning in Walnut has full details.
Duct Sealing in Walnut
Sealing is the fix for the disconnected and leaking ducts we find in Walnut’s 1980s builds. We apply duct sealing mastic and reinforced tape at joints, then pressure-test the system to verify the seal holds. In Snow Creek and similar neighborhoods, this can recover 15 – 25% of conditioned air that’s currently bleeding into attics. Duct Sealing in Walnut explains when sealing beats replacement.

FAQs About Air Duct Cleaning Company in Walnut
No permit is required for routine duct cleaning or dryer vent cleaning in Walnut. Duct sealing that involves no structural modification or electrical work typically does not require a permit either, though HOA communities like Walnut Valley may have notification requirements for work involving rooftop access. We can provide a written scope if your association asks.
Walnut’s fall Santa Ana events push fine dust through outdoor HVAC intakes and attic vents, and we’ve seen systems need cleaning 20 – 30% sooner after heavy wind seasons. If you notice more dust settling after a wind event, or your filters clog faster, the ducts have likely taken in debris. Call (361) 326-5060 and we’ll assess whether cleaning or just filter upgrade is the right move.
Yes. Our rotary brush systems and negative-air machines are modular for tight spaces, and our technicians are trained to work in constrained Walnut attics without damaging ductwork or insulation. If your attic is exceptionally small, we’ll note it when scheduling so the crew brings the compact kit, not the full-size rig.
