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 Westmont, CA
Air duct cleaning in Westmont costs between $320 and $580 for most homes, depending on how many returns and how much debris has settled inside. Westmont homes need it more urgently than most because the neighborhood sits directly beneath LAX flight approach and departure corridors, and is wedged between the I-110 and I-105 freeways. That combination pushes jet-fuel exhaust residue, tire dust, and diesel soot into HVAC systems far faster than in cleaner-air LA neighborhoods. Call (980) 447-2498 for a written quote before any work begins.
Why Westmont Homes Are Different
Westmont is an unincorporated LA County community, not an incorporated city. That matters more than people expect. Code enforcement here is lighter-touch than in incorporated cities, so when a bungalow changes hands, nobody flags an aging duct system. The result is that many Westmont homes still run their original sheet-metal or early flex-duct runs from the 1940s through 1960s, and we routinely find collapsed flex sections, disconnected joints, and decades of layered contamination on a first visit.
The housing stock itself compounds the issue. Most homes are small post-WWII bungalows and modest ranch houses where maintenance has often been deferred through rental turnover or tight budgets. We find ducts that have never been pressure-tested. We also encounter something unique to Westmont’s era of construction: original duct insulation wrapped with asbestos-containing tape. It is common enough that we recommend an asbestos survey before any aggressive duct agitation. Homeowners are usually surprised. The house feels “just old, not that old,” but the product era is real, and Westmont’s 1950s housing tracts carry it more than most LA neighborhoods.
Westmont’s position in the low-lying South LA Basin adds another layer. Temperature inversions regularly trap freeway and airport particulates at ground level, and they push ultra-fine particles indoors even when the weather is mild. Summer inversion events are the worst. The indoor air gets measurably worse not because it is hot, but because the outdoor air is getting pushed into the home and cycling through dirty ductwork.
Our Main Westmont Services
Three services cover nearly every Westmont call we take: full air duct cleaning, dryer vent cleaning, and air duct repair. Each has its own Westmont page, because the work involved and the conditions that drive it are different for each one.
Air Duct Cleaning in Westmont
Westmont duct cleaning usually means removing years of accumulated freeway soot, pet dander, and construction debris from the interior surfaces of the duct runs using negative-pressure extraction. That is the trade term for pulling the whole system into a vacuum and agitating the duct walls so the debris releases and gets captured, not blown around the house. In Westmont, the debris load is heavier than average because of the airport and freeway proximity. Most homes need every return, every supply run, and the main trunk line done in one visit. See exactly what the job involves on our Air Duct Cleaning in Westmont page.
Dryer Vent Cleaning in Westmont
Westmont’s older ranch homes often have longer dryer vent runs than modern builds, and plenty of them still have original vent routing that no one has inspected since installation. Lint builds up faster when a vent has a slight dip or a long horizontal segment. We see dryer vent lint trap bypasses in Westmont more than in newer subdivisions, because homeowners do not realize the secondary lint trap behind the dryer is clogged. Every job gets a written price and a full lint-depth check. Read more on our Dryer Vent Cleaning in Westmont page.
Air Duct Repair in Westmont
Collapsed flex runs and disconnected joints are common in Westmont, because the original ductwork is often still in place and was never pressure-tested. When a section collapses or separates, the system pulls unconditioned air from the crawlspace or attic, and heated or cooled air leaks out before it reaches the rooms. We repair or replace the failed sections, seal the joints, and test the airflow. Every repair receives a written guarantee, and if a covered repair does not hold, we return at no charge. Details are on our Air Duct Repair in Westmont page.

What pushes a Westmont quote higher is usually the age of the home and what the tech finds once the system is opened: collapsed flex runs, disconnected joints, or asbestos-containing tape that needs a survey before any aggressive cleaning. That is exactly why we put the price in writing before any work begins, so the number on the table is the number on the invoice, no surprise line items at the end.

What Westmont Customers Say
"Tech arrived with a badge and a printed sheet of what he'd be doing. Ran a camera through the main trunk before and after so I could see the dust difference. Vents smell cleaner already."
- Gina R."Priced by the system, not by the vent, and he told me up front. No pressure to add the sanitizer and I said no without any fuss."
- Faith N."We had construction dust packed into every register after a remodel. They sealed off the returns, used negative pressure, and left the floors cleaner than they found them."
- Paul E.
