We’ve been working in Koreatown since 1984. We know the courtyard apartments off Wilshire, the retrofitted mixed-use buildings along Western, and the older mid-rises near Olympic. These aren’t generic LA structures. They’re pre-1960 buildings with galvanized ductwork, piecemeal flex-duct additions, and HVAC systems that were never designed for today’s density or the ground-floor Korean BBQ restaurants pumping grease aerosols up through shared ventilation. When you call Bellows, you’re getting a crew that understands what “Koreatown clean” actually means.
Why Bellows Air Duct & Vent Co. Is Koreatown’s Preferred Air Duct Cleaning Company
Our reputation in Koreatown was built on showing up when we say we will and leaving the ducts cleaner than we found them. We’ve got a strong base of repeat customers in ZIP 90005, many in the same buildings we’ve serviced for ten or fifteen years. They call us back because the job holds up.
We answer our phones 24 hours a day. Not an app. Not a voicemail tree. A live person at our office who can dispatch a background-checked, uniformed technician to Koreatown, usually next-day. Ray Castillo, our owner, insists on it. He’s been running Bellows since 1984, and that personal accountability still drives how we operate.
Every job gets a camera inspection before and after. You see what we see. No claims without proof. Our Air Duct Cleaning team documents the condition of your ductwork, the work performed, and the final result. That video record is yours to keep.
We’re also the company that doesn’t bait-and-switch. The price we quote on the phone is the price on the invoice. Period. No scare tactics. No coupon traps. One honest price, shown before we start.
Our Air Duct Cleaning Services in Koreatown
Residential Duct Cleaning
Koreatown’s residential stock is old. Courtyard apartments, converted duplexes, small mid-rises built before 1960 with galvanized steel ducts that have never been properly cleaned. We see it constantly on Irolo, on Kingsley, on the side streets off Vermont. These systems accumulate decades of dust, debris, and in buildings near Korean BBQ corridors, a sticky grease film that dry brushing won’t touch. Our residential service includes full supply and return cleaning, register and grille removal, and HEPA vacuuming. Most Koreatown residential jobs run $280-$420 and finish in one visit.

Commercial Duct Cleaning
This is where Koreatown gets complicated. Mixed-use buildings with restaurants on the ground floor and residences above. Shared HVAC infrastructure. Grease-laden exhaust migrating through return-air pathways into ducts that were designed for light residential use. We tackled a mixed-use building on Wilshire where return-air vents in shared hallways had been pulling grease from a BBQ restaurant’s exhaust stack into the residential ducts above. Our crew used a Rotobrush system with a degreasing pre-treatment to break down the sticky film, followed by a full-system cleaning with HEPA vacuuming and a post-cleaning video inspection to verify the restoration. Commercial and mixed-use jobs in Koreatown typically range $450-$1,200 depending on system size and contamination level.

Supply Duct Cleaning
Supply ducts push conditioned air into your living spaces. In Koreatown’s older buildings, these are often undersized for current occupancy loads and coated with debris that restricts airflow. We clean the full supply trunk and branch lines, replace damaged flex connections, and seal leaks where we find them. Supply-only cleaning runs $180-$320 in Koreatown, though we typically recommend full-system service for buildings with shared ventilation.

Return Duct Cleaning
Return ducts are the intake side. They’re also where Koreatown’s unique problems show up first. Leaky returns in common hallways pull in street-level PM2.5 from Wilshire and Olympic traffic. In mixed-use buildings, they pull in grease and cooking particulates from restaurant ventilation. Cheap cleaning crews use only dry brushing on grease-laden ducts, simply redistributing the film deeper into the system. We don’t. Our return duct service includes pathway sealing after cleaning to prevent recontamination. Return-only cleaning in Koreatown: $160-$300.

Trusted Brands We Service in Koreatown

For our Koreatown customers, this means we can source replacement parts and filtration upgrades without long lead times. A Honeywell media filter upgrade for an older Koreatown system, an Aprilaire whole-house air purifier for a courtyard apartment with persistent odor issues, or Nikro HEPA vacuuming equipment for post-construction cleanup. We stock what we need to finish the job in one visit. Most Koreatown customers never wait on parts.
Common Air Duct Cleaning Problems We See in Koreatown Homes
- Grease-contaminated ductwork from adjacent Korean BBQ restaurants. Standard residential cleaning protocols underestimate and undercharge for this. The sticky, odor-trapping film requires degreasing pre-treatment and extended contact time. Dry brushing just moves it around.
- Original galvanized ductwork with decades of accumulated debris. ZIP 90005’s pre-1960 buildings often have never been properly cleaned. The buildup is hardened, layered, and restricts airflow significantly. These systems need aggressive but careful mechanical cleaning.
- Undersized flex-duct patchwork from retrofits. Piecemeal additions never designed for current HVAC loads. They collapse, kink, and trap debris. We document these with video inspection and recommend repair or replacement where needed.
- Leaky building envelopes pulling in street-level particulates. Temperature inversions in the central LA Basin trap PM2.5 at street level. Heavy traffic on Wilshire, Olympic, and Vermont pushes these particles into older buildings with poor sealing. Cleaning without sealing the return pathways is temporary at best.

FAQs - Air Duct Cleaning in Koreatown
Every 12-18 months for units in buildings with active restaurant exhaust on the ground floor. The grease aerosols and charcoal smoke particulates accumulate faster than standard household dust, and once the sticky film sets, it traps odors and restricts airflow more aggressively. Residential buildings without adjacent commercial cooking can typically go 3-5 years between cleanings. Call (844) 685-6342 to schedule a video inspection and we’ll tell you exactly where your system stands.
Yes. We apply a commercial degreasing pre-treatment before mechanical agitation with our Rotobrush system. Dry brushing alone won’t dissolve the film. The degreaser breaks the bond, then HEPA vacuuming removes it completely. This protocol adds time and material cost, which is why we assess with camera inspection before quoting. Call for a free estimate.
Yes. Our camera inspection reveals the distinct amber-brown coating and pooled residue characteristic of grease contamination, versus standard gray household dust. We show you the footage before and after cleaning. The difference is obvious. Video inspection is included with every full-system service, or available standalone for $125-$195.
Sometimes, but coverage varies by policy and by whether the ducts serve common areas versus individual units. We recommend checking your specific policy language for “HVAC maintenance” or “indoor air quality” provisions. We’re happy to provide a detailed written scope and documentation to support any claim. Call (844) 685-6342 and we’ll walk you through what’s typically required.
We use Rotobrush mechanical agitation systems, Nikro HEPA vacuuming equipment, and support filtration from Honeywell and Aprilaire. For Koreatown’s grease-heavy mixed-use buildings, this combination of mechanical brushing, chemical pre-treatment, and sealed HEPA containment gets the job done in one visit. We’ve been running this equipment since before most of the discount operators in LA opened shop.
