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 HVAC Cleaning Across Westmont
HVAC cleaning in Westmont means removing what the 110 freeway and the surrounding industrial basin push into your ducts: a fine black particulate film that most coastal LA neighborhoods never deal with. A full system clean, including the air handler, blower, and evaporator coil, typically runs $425-$780 in Westmont depending on system size and access. Our crews are in Westmont weekly, know the 1940s-1960s housing stock here, and quote every job with one written price before any panel comes off. Call (806) 606-6902 if you want a number in writing, not a range over the phone.
We coordinate dispatch from our Los Angeles office and serve Westmont with local crews who know the difference between a 1950s galvanized trunk line and a 1990s flex-duct retrofit. That matters here more than in most places.
Why CleanRun Air Duct Cleaning Is Westmont’s Preferred HVAC Cleaning Company
CleanRun has been documenting every job with before-and-after photos since 2013, serving 52,000+ homes across LA County. In Westmont specifically, our techs see a pattern few other areas produce: original sheet-metal ductwork from the post-WWII build-out, still in service, filming over with diesel soot pulled in through unsealed return chases near the 110. We know where to look, what it looks like, and what it takes to actually remove it rather than spray over it.
Every Westmont visit ends with a Documented Photo Record: the inside of every duct run, before and after, handed to you as part of the job record. That’s not an upsell. It’s standard, written into the H.A.V.E.N. Standard we operate under, and it exists because a camera inside your ducts tells the truth that a fogging machine cannot. Tomas Reyes leads our crews, and every tech is background-checked, uniformed, and identified by name before they enter your home.
Westmont homeowners buy homes here at a high price point and then inherit duct systems that haven’t been professionally accessed in decades. We write the scope, the price, and the warranty before work starts. You get the photo record after. No surprises in between.
Our HVAC Cleaning Services in Westmont
Evaporator Coil Cleaning
The evaporator coil sits inside your air handler and is the single biggest efficiency choke point in a Westmont home. A coil caked with the fine black particulate that drifts off the 110 corridor and from Gardena and Compton industrial operations has to work harder to transfer heat. That means longer run times, higher summer bills, and more particulates cycling through the house. Evaporator coil cleaning in Westmont runs $180-$320 as a standalone service, or is folded into a full system clean. We use negative-pressure extraction so the debris removed from the coil doesn’t get redeposited downstream in the supply runs.
Blower Cleaning
The blower wheel moves every cubic foot of air your system delivers. In Westmont’s inland summer heat, the blower runs harder than in beach cities, drawing more of the 110 and industrial corridor air through the return side. A blower wheel coated with caked dust and diesel soot moves less air per rotation, which stresses the motor and shortens its life. Blower cleaning in Westmont typically costs $140-$240 and includes camera verification that the wheel and housing are clean after extraction, not just wiped down.
Condenser Cleaning
Your outdoor condenser coil collects Westmont’s particular mix of road dust, industrial fallout, and the fine grit that blows off the rail lines and freight corridors nearby. A clogged condenser coil drives head pressure up and cooling capacity down. We clean coils with professional-grade equipment, and we name the brands: Abatement Technologies and Rotobrush are what you’ll see on our trucks. Condenser cleaning in Westmont runs $150-$290 depending on coil depth and access.
Air Handler Cleaning
The air handler is where most of Westmont’s duct contamination originates: the cabinet, the coil, the blower, the drain pan. Left untouched, it re-seeds cleaned duct runs with whatever was growing or accumulating inside it. That’s why a legitimate HVAC Cleaning job always starts here, not at the register covers. Air handler cleaning in Westmont runs $225-$400 depending on system type. In the 1940s-1960s bungalows that dominate Westmont housing stock, the handler is often tucked into a closet or garage alcove, which affects access time and cost.

BeforeAfterTrusted Brands We Service in Westmont
We service all major brands found in Westmont homes, and where systems have been retrofitted or partially upgraded, we work with Honeywell and Aprilaire components regularly, including media filters, UV lamps, and whole-house dehumidifiers integrated with the HVAC system. Most Westmont homes still run the original furnace or air handler from the 1950s or 1960s, paired with newer condenser units. We carry common replacement parts and can source what we don’t stock without sending you into a weeks-long wait for a part that should be on a shelf in LA. For air quality add-ons, we install and clean Guardsman and Aprilaire components, and we’ll tell you plainly which ones are worth it for Westmont’s particle load, and which are not.
Common HVAC Cleaning Problems We See in Westmont Homes
- Black soot film in original 1950s galvanized trunk lines. This is Westmont’s signature problem. Diesel particulates from the 110 freeway get pulled through unsealed return-air chases in homes where the original sheet-metal ductwork was never pressure-sealed. The film builds inside the trunk line, and standard filter replacement won’t touch it.
- Collapsed or delaminated flex duct in rental properties. A high proportion of Westmont units are long-term rentals with deferred maintenance histories. Flex duct from the 1980s and 1990s that should have been replaced a decade ago collapses or delaminates internally, trapping moisture and re-seeding mold after every clean. We find it on the camera and we show it to you.
- Marine-layer inversion trapping particulates at ground level. Westmont sits under a pollution convergence zone where marine-layer inversions hold freeway and industrial emissions near street level. That’s not a winter-only problem; it’s a year-round particulate loading issue that lands directly in your return air and, from there, inside your ductwork.
- Drain pan and coil moisture trapping in tight closets. The 1940s-1960s ranch-style homes here put air handlers in cramped closet spaces with poor ventilation. Moisture from the coil and drain pan doesn’t dry out fast, especially in rental units where filters weren’t changed for years. That’s where the mold spots start.
Pricing for HVAC Cleaning in Westmont, CA
Here’s what you can expect to pay in Westmont for legitimate HVAC cleaning, written in dollars, before any work begins. A single-system full HVAC cleaning, including air handler, blower, evaporator coil, and supply/return duct runs, runs $425-$780 for the homes we typically see here. A split-system home with a single air handler falls at the lower end. Homes with older metal trunk lines, long duct runs, or poor access to the handler land at the higher end. Condenser-only cleaning runs $150-$290. Blower cleaning runs $140-$240. Evaporator coil cleaning runs $180-$320 standalone. Air handler cleaning runs $225-$400.
What drives cost in Westmont specifically is access and duct condition. Tight closet installations from the post-WWII build-out, collapsed flex duct that needs replacement rather than cleaning, and return-air chases that need pressure-sealing all add labor. We give you one written price for the whole system before work starts. No per-vent pricing, no bait-and-switch, no “well, once we got in there we found…” surprises. Haven Standard Clause 1: written price before any work starts, every time. Call (806) 606-6902 for an exact number on your system.

FAQs - HVAC Cleaning in Westmont
Because the black film is diesel soot and industrial particulate from the 110 freeway corridor and nearby Gardena and Compton operations, and it’s being actively pulled into your ducts through unsealed return-air chases that were never pressure-sealed. If you clean the ducts but don’t seal those chases, the source keeps feeding the system. A proper clean removes the existing film and seals the return path so exhaust stops being drawn in. That’s the difference between a source-removal clean and a vacuum pass.
Both. Westmont’s inland position means summer humidity fluctuates, but the bigger issue is the marine-layer inversion that traps moisture near ground level and the tight closet installations in the 1940s-1960s bungalows here, where air handlers don’t get enough ventilation. In rental units with long filter-change gaps, the coil and drain pan stay wet longer and the flex duct traps that moisture. We identify the specific source with a camera inspection before recommending anything.
A fogging sanitiser coats the surface it touches, but it won’t remove the soot film, the trapped moisture, or the delaminated flex duct that’s feeding the mold. In Westmont’s pollution-loaded ductwork, fogging seals the particulate in place rather than removing it. You need source removal: negative-pressure extraction, mechanical agitation, and pressure-sealing of the return path. Anything else leaves the problem in the trunk line, a few weeks from resurfacing.
Every 3-5 years for units near the 110 corridor or downwind of industrial operations, or if you can see black film around the register covers. Westmont’s particulate loading is higher than LA’s beach or hillside neighborhoods, so the 3-year mark is more appropriate here than the 5-year mark. If the unit hasn’t had the ducts professionally accessed since installation, do a camera inspection first. The tenant smells it before the landlord sees it.
Yes, and in Westmont we often start there. Air handler cleaning, blower cleaning, and evaporator coil cleaning can be done as standalone services, which is useful for rental turnover or for homes that had duct cleaning done recently but skipped the handler. We’ll show you on camera what the handler looks like and what the ducts look like, then you decide. One written price for the scope you approve, before work starts. Call (806) 606-6902 and we’ll give you a number in writing.
