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, CA typically runs $290 – $490 for a standard single-system home, with most jobs completed in a single visit. Westmont’s older housing stock and its location just east of the 110 mean ducts here collect a particular mix of freeway dust, pet dander, and decades of accumulated debris. Cardinal Air Duct Cleaning serves Westmont with upfront written pricing, before-and-after photo proof, and a 365-day guarantee on every job. Call (737) 727-2314 for a free estimate.
Why Westmont Homes Are Different
Westmont sits in an unincorporated pocket of South Los Angeles County, bordered roughly by Vermont Avenue to the west and Imperial Highway to the south. Most of the residential streets off Normandie and Vermont are lined with single-story stucco homes built between the 1940s and 1970s. Those homes almost always have galvanized steel ductwork, and after forty or fifty years that metal develops pinhole leaks at the seams and joints. Leaky ducts pull crawlspace air and attic dust into the system, which is why a Westmont cleaning so often reveals far more than the homeowner expected.
The climate plays a role too. Westmont gets long dry spells where fine dust settles on every exterior surface, and the Santa Ana winds push that grit into any gap around windows, doors, and foundation vents. Homes near the 110 corridor, particularly around 108th and 109th Streets, accumulate a gray-black film inside return registers that surprises people. Add in pet hair from the area’s many multi-dog households and the ducts in a Westmont home can carry a heavy load. Omar Haddad, who leads our Westmont team, notes that the single biggest complaint he hears on arrival is “we didn’t know it could get this bad back there.”
Our Main Westmont Services
Most Westmont homeowners reach out to us for one of three jobs, and each has its own dedicated Westmont page with full pricing and process details. Here’s a quick overview of what each service involves in this area.
Dryer Vent Cleaning in Westmont
Westmont’s older laundry rooms often route dryer vents through the attic or crawlspace, which means longer runs with more elbows than newer construction. That configuration traps lint fast, and we regularly pull out dense compacted plugs from runs that exit at the roofline. Our crews run a rotating brush the full length of the vent and then vacuum from the exterior with a Nikro HEPA unit, leaving nothing behind. Full details are on the Dryer Vent Cleaning in Westmont page.
Air Duct Cleaning in Westmont
A standard Westmont air duct cleaning covers all supply and return ducts, the return boot, and the main trunk line. We use a Rotobrush rotary brush system paired with negative-pressure extraction, which means loosened debris goes straight into the vacuum rather than back into your living room. Homes with the original 1950s metal ducts benefit the most, since those systems haven’t been opened in decades. See the Air Duct Cleaning in Westmont page for full scope and pricing.
HVAC Cleaning in Westmont
Westmont HVAC systems are typically older furnace-and-coil setups, and the evaporator coil is the part most homeowners never see until airflow drops. We pull the coil access panel, inspect for corrosion and buildup, and clean it with a non-acidic coil cleaner. The blower wheel and motor housing get brushed and vacuumed as well, which quiets the system and restores airflow. The HVAC Cleaning in Westmont page covers the full process and what to expect.

No. Air duct cleaning, dryer vent cleaning, and HVAC cleaning are considered routine maintenance and do not require permits anywhere in Westmont or unincorporated Los Angeles County. Some HOAs in the area may have rules about rooftop work, but our crews work from inside the home or from standard ladders at ground level, so this rarely comes up.
Every Cardinal job includes before-and-after photos of your own ducts, taken inside the registers and return boot. You’ll see what the system looked like when we arrived and what it looks like when we leave. Those photos arrive with your digital invoice, which you can pay from a link on your phone.
