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.

AfterFast, Reliable Air Duct Cleaning Across Westmont
Air duct cleaning in Westmont, CA typically costs between $380 and $720 for a full single-system home, and most jobs take three to five hours once our crew arrives. Westmont’s position along the 110 freeway corridor means ducts here collect a diesel-heavy soot film that coastal LA homes rarely see. We know these houses, we know this air, and we arrive with the right equipment to document the before-and-after. Call (806) 606-6902 to get a written price before any work starts.
Why CleanRun Air Duct Cleaning Is Westmont’s Preferred Air Duct Cleaning Company
We’ve worked in enough Westmont homes to know what’s waiting inside the ductwork. The post-WWII bungalows along Vermont Avenue, the 1950s ranch houses off West 108th Street, the smaller stucco rentals clustered near Athens Park: these systems share a history of deferred maintenance, unsealed return chases, and decades of particulate loading from the 110. That’s not a generic dust problem. It changes what we do, how long it takes, and what the before photos show.
Every job ends with a Documented Photo Record, and every job starts with a written price. That’s Haven Standard Clause 1, and it’s not a courtesy, it’s the contract. Tomas Reyes, who leads CleanRun, built the company in 2013 on the belief that homeowners should be able to see what they’re paying for, not just hear a technician’s summary. Since then we’ve served more than 52,000 homes across Los Angeles County, and Westmont’s specific conditions remain some of the most predictable in the metro.
Our technicians are background-checked, uniformed, and identified by name before arrival. They know Westmont’s housing stock because they’ve spent hundreds of hours inside it. When a return-air chase in a 1955 house is pulling diesel exhaust into the air handler, that’s not a surprise to us. It’s what we expect to find and document.
Our Air Duct Cleaning Services in Westmont
Residential Duct Cleaning
Most Westmont homes run a single forced-air system feeding six to ten registers. Our residential service covers the full loop: supply plenum, each supply run, each return chase, and the air handler cabinet. Because so many of these 1940s-1960s systems have never been pressure-sealed, we pay close attention to where outside air is entering the return side. The black soot film we find in Westmont trunks almost always traces back to unsealed return chases near the foundation or crawlspace. You’ll see it in the before photos.
Commercial Duct Cleaning
Westmont’s commercial stock is mostly low-rise offices, storefronts along Vermont and Imperial, and a handful of medical and dental suites. These spaces often share the same soot exposure as homes, but add higher occupant density and longer runtime hours. We schedule commercial work around your operating hours, provide the same written price upfront, and deliver the same photo record for every run we access.
Supply Duct Cleaning
In Westmont, supply ducts carry the added burden of dust drawn in through leaky returns and pushed out through aging flex connectors. When that flex duct delaminates, the inner liner sheds particles long after the cleaning is finished. We inspect every supply run with a camera before we agitate, so we can tell you whether the duct itself is failing or just dirty. If it’s failing, we say so in the written scope before work begins.
Return Duct Cleaning
This is the service Westmont homes need most. Return ductwork in these older houses is frequently undersized, unsealed, and pulling air from wall cavities, crawlspaces, and anywhere else negative pressure can find. That means the return side is where most of the freeway soot enters the system. We treat return cleaning as its own task, not an afterthought, and we photograph every return run before and after. If a return chase needs sealing to stop the soot from coming back, that goes in the written recommendation, not as a surprise upsell.

Our Air Duct Cleaning crews work with equipment from Rotobrush, Nikro, and Abatement Technologies, alongside monitoring and filtration components from Honeywell and Aprilaire. We carry OEM-compatible replacement media and seals for Honeywell and Aprilaire systems on the truck, which means we can often address filter housing and media issues the same day. If you have a Guardsman filter rack or an older Aprilaire cabinet installed in a Westmont ranch house, we know how it fits and what it needs.
Common Air Duct Cleaning Problems We See in Westmont Homes
- A thin black soot film on galvanized trunks. This is the signature Westmont problem. Decades of diesel exhaust from the 110 corridor and industrial drift from Gardena and Compton get pulled through unsealed return chases and then baked onto duct walls by inland summer heat. It requires mechanical agitation and HEPA-filtered negative pressure to remove, not a quick vacuum pass.
- Collapsed flex duct in rental properties. Westmont has a high proportion of long-term rentals. When a flex run collapses or the inner liner delaminates, the system keeps shedding particles after cleaning. We identify this during video inspection and put the repair or replacement in the written scope before cleaning starts, so there’s no surprise invoice.
- Overloaded blower motors. Heavy soot loading forces the blower to work harder, shortening bearing life and reducing airflow. In Westmont, we often see blower wheels caked with a greasy black deposit that was once airborne diesel particulate. A blower that’s cleaned during duct service runs quieter and pulls fewer amps.
- Unsealed return-air chases in 1940s-1960s homes. These houses were built before return-side sealing was standard practice. The return path often includes open wall cavities and joist bays, which means the system is inhaling whatever is in the walls and crawlspace. Cleaning the ducts without addressing the chase is a half measure. We flag it, photograph it, and quote sealing as a separate line item if you want it done.

FAQs - Air Duct Cleaning in Westmont
Westmont sits directly east of the 110 freeway and downwind of industrial operations in Gardena and Compton. Diesel particulates and industrial dust settle into the air, and with the marine layer acting as a lid, that pollutant load stays at ground level. Older homes with unsealed return chases draw that air into the duct system, where the soot films onto galvanized surfaces. Coastal neighborhoods get marine air; Westmont gets freeway air. That’s why the cleaning interval here is shorter. Call (806) 606-6902 for an exact assessment.
For a rental unit within a mile of the 110 with original or early-replacement ductwork, we recommend every three to four years, and sooner if tenants report a diesel smell when the AC starts. If the property has flex duct that’s already delaminating, cleaning alone won’t solve the particle shedding, and the duct replacement should be scheduled first. We give landlords the same written price and photo record we give owner-occupants. Call (806) 606-6902 and we’ll assess the system in writing.
Yes. The ductwork isn’t torn apart to clean it. We access the system through existing register openings and the plenum, run agitation tools through every accessible run, and extract with HEPA-filtered negative pressure. The sheet-metal trunk remains intact. What you get afterward is a photo record of every run, inside, so you can see the metal, not just hear that it was cleaned. Call (806) 606-6902 for a written quote on your specific layout.
Yes, more than almost any other part of the system. In 1940s-1960s houses with unsealed return chases, the return side is where most of the soot and outside air enters. We treat return cleaning as a dedicated part of the job, not a quick pass. The before photos from Westmont return runs are often the most dramatic in the whole system. If we find a chase that’s pulling from a crawlspace, we’ll photograph it and put sealing in the written recommendation. Call (806) 606-6902 to schedule a video inspection.
In many cases, yes. A blower wheel caked in soot moves less air, which means longer runtimes and warmer rooms during Westmont’s July and August heat. When the blower, evaporator coil, and ducts are cleaned, airflow improves and the system doesn’t work as hard to hit the thermostat. It’s not a fix for a failing compressor, but it removes the most common airflow penalties we see in older Westmont homes. Call (806) 606-6902 and we’ll give you a written price for the full system clean.
