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 comes down to one thing: this is a community living directly underneath three overlapping pollution sources that most of LA County doesn’t share. The I-110, the I-105, and the LAX flight corridor all converge over Westmont, and that means your ductwork is collecting diesel soot, tire particulates, and aviation emissions at a rate that would surprise homeowners in quieter parts of the county. Most Westmont homes run between $390 and $720 for a full-system duct cleaning, depending on home size and how much that freeway air has deposited inside. Call us at (469) 972-3151 and we’ll give you a written price before any work begins.
Why Westmont Homes Are Different
Westmont’s housing stock tells a specific story. The homes here are predominantly small single-family houses and duplexes built between the 1940s and early 1960s, when this was unincorporated county land with working-class roots. Many started with floor furnaces or wall heaters. Central HVAC came later, often as a retrofit done on a tight budget, which means duct runs were frequently routed through old floor-furnace cavities or pulled through attics without proper sealing at the connections. Those unsealed joints have been drawing unfiltered air directly into living spaces for years.
What settles inside those ducts is worse than ordinary household dust. Westmont sits in the air corridor between the Harbor Freeway and the Century Freeway, with LAX departures climbing out to the west. Diesel particulates from truck traffic, ultrafine particles from brake and tire wear, and aviation emissions combine into a fine, sticky soot that coats duct walls and doesn’t move on its own. Mild winters mean furnaces run infrequently, so that material sits undisturbed. Summer marine-layer humidity then interacts with it, and in older duct systems, that’s how microbial growth gets started. Technicians working in Westmont see this pattern constantly: decades of freeway-adjacent air settlement, compounded by HVAC retrofits that were never properly sealed in the first place.
Our Main Westmont Services
Westmont homeowners call us about two things: the air ducts that haven’t been cleaned since the house was built, and dryer vents that are pushing lint into walls and attics. Here’s what each involves.
Air Duct Cleaning in Westmont
Our Air Duct Cleaning in Westmont work starts with an inspection of your supply and return runs, paying close attention to the retrofit connections common in this area’s 1940s-to-1960s housing stock. We use Rotobrush rotary systems to break debris loose at the duct wall, then Nikro negative-pressure units to pull everything out while Abatement Technologies HEPA filtration keeps loosened particles from re-entering the living space. Dale Whitmore has been direct about what Westmont homeowners should expect: if your home sits within a mile of the 110 or 105, your ducts are working harder than the average LA County system.

Dryer Vent Cleaning in Westmont
Our Dryer Vent Cleaning in Westmont addresses a fire hazard that gets worse in this housing stock. Many Westmont homes have short, angled dryer vent runs retrofitted through original wall cavities, and those tight bends catch lint fast. We remove the accumulated buildup mechanically, clear the entire run to the exterior termination point, and make sure the connection at the dryer is seated correctly. Dale Whitmore’s crew has pulled enough compacted lint from South LA vents to know that a vent that hasn’t been cleaned in two years is a vent that’s already restricting airflow.

"Our dryer was taking two cycles to dry a load. They cleaned the vent and pulled out a frightening amount of lint. Dries in one cycle now and honestly I feel better about the fire risk."
