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.
Air Duct Cleaning Company in Westmont, CA
Air duct cleaning in Westmont, CA typically runs $450 – $850 for a whole-home system, with most jobs completed in a single visit. What sets Westmont apart is the housing stock: thousands of 1950s – 60s tract homes with original galvanized steel ductwork that’s now corroding and flaking after 60 – 70 years in the dry, dusty air. We’re Hollis Air Duct Cleaning, part of the Garrison Partners family, and we treat Westmont jobs as restoration work, not routine maintenance. Call us at (361) 326-5060 for a free estimate.
Why Westmont Homes Are Different
Westmont’s single-story, three-bedroom homes were built fast between 1950 and 1970, and most still run on the original galvanized steel ducts. That metal is now 60 – 70 years old. In the dry Santa Ana wind cycles, it corrodes internally and sheds rust flakes into the airflow. We regularly pull handfuls of reddish particulate from trunk lines that other regions never see.
The dry climate here means ducts don’t rot from humidity, but dust and allergens stay airborne longer and pack into seams and corners. Nearby freeway corridors add diesel particulate to the mix. And the distinctive issue in Westmont: original 1950s installations used asbestos-wrapped joints on older connections. Our technicians identify this before touching anything, notify the homeowner, and follow proper handling protocols. No surprises, no shortcuts.
We dispatch and schedule from our Los Angeles office, with crews serving Westmont locally and arriving inside the quoted window.
Our Main Westmont Services
Westmont homeowners call us for three jobs that address the specific condition of aging duct systems in this market.
Air Duct Cleaning in Westmont
We clean the full supply and return network using a Rotobrush rotary brush system paired with negative-air extraction. In Westmont, this means dislodging corroded metal flakes and packed dust from 60-year-old galvanized trunk lines, not just vacuuming surface debris. We inspect for asbestos tape before starting and photo-document the before-and-after condition of every run. Air Duct Cleaning in Westmont

Dryer Vent Cleaning in Westmont
Dryer vent blockages in Westmont often combine lint with exterior dust caked on by Santa Ana winds. We run a rotary brush through the full vent line to the termination point, check airflow with a manometer, and verify the dryer exhausts properly before leaving. A blocked vent in a 1950s laundry closet with limited clearance is a fire hazard we take seriously. Dryer Vent Cleaning in Westmont

Duct Sealing in Westmont
Original Westmont ductwork has loose joints and gaps where metal meets the plenum. We seal accessible seams with mastic and reinforce with mesh, reducing leakage that wastes conditioned air into attics and crawl spaces. In homes with corroded galvanized steel, sealing is often the step that makes cleaning worthwhile, preventing recontamination from attic dust. Duct Sealing in Westmont
