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.
Fast, Reliable HVAC Cleaning Across Koreatown
HVAC cleaning in Koreatown means dealing with a problem most of Los Angeles never faces: grease. Not the grease from your own stove, but the airborne aerosol from hundreds of Korean BBQ grills saturating the air around Wilshire, Western, and Olympic every evening. Your rooftop intake pulls that air through your ducts and across your evaporator coil, where it condenses into a sticky film that ordinary duct cleaning never fully removes. We’re CleanRun Air Duct Cleaning, and we photograph the inside of every duct run before and after the work, so you can see exactly what was there and what’s gone. Call (806) 606-6902 for a written price before any work starts.
Why CleanRun Air Duct Cleaning Is Koreatown’s Preferred HVAC Cleaning Company
Koreatown’s housing stock is unlike anywhere else we work. Dense 1940s-through-1970s apartment buildings, rooftop package units, shared duct chases between units, and the highest concentration of Korean BBQ restaurants per square mile in North America. That combination produces duct interiors we don’t see in Westlake or Mid-Wilshire: yellowish-brown grease film on evaporator coils, carbon particulate from charcoal smoke, and moisture that binds it all together. Our crews know what a Koreatown coil should look like, because we’ve opened enough of them to recognize the difference between normal dust and restaurant-exhaust saturation. Since 2013, we’ve served 52,000+ homes, every one with a written price before work began and a documented photo record when the crew left.
Every technician who arrives at a Koreatown building is background-checked, uniformed, and identified by name before the truck door opens. That’s Haven Standard Clause 3: Verified Crews. You don’t get a subcontractor in an unmarked van. You get a written scope of work, a named technician, and a job record that includes photos of every duct run, inside, before and after.
Our HVAC Cleaning Services in Koreatown

Evaporator Coil Cleaning
In Koreatown, the evaporator coil is ground zero for restaurant grease. The coil sits downstream of your return air intake, and when intake air carries BBQ aerosols, the coil’s cold, wet surface traps them. We’ve pulled coils from buildings within a block of 6th and Western that carried a film thick enough to reduce airflow by a measurable margin. Evaporator coil cleaning in Koreatown typically runs $180 to $340 depending on access and coil condition. We use negative-pressure extraction and HEPA-filtered agitation, then photograph the coil before and after so the record is unambiguous.

Air Handler Cleaning
The air handler is the box that houses the blower and coil, and in Koreatown’s older apartment stock it’s often a rooftop unit that hasn’t been opened in years. We clean the blower wheel, the housing interior, the drain pan, and the coil within the handler. On a 1960s building near Wilshire and Irolo, our crew opened an air handler and found a yellowish-brown grease film across the evaporator coil that traced directly to grill exhaust from nearby restaurants. Air handler cleaning in Koreatown runs $220 to $380 for most residential systems. The photo record shows you exactly what was inside.

Condenser Cleaning
The condenser coil lives outside or on the roof, where Koreatown’s air does its worst. Freeway dust from the I-10/US-101 interchange settles into the coil fins, and during Santa Ana events, desert dust does the same. A fouled condenser coil drives up your electric bill because the system works harder to reject heat. Condenser cleaning in Koreatown runs $120 to $220 for typical residential units, and the work includes fin combing where needed. It’s the least expensive service on this page and the one most likely to pay for itself in avoided compressor strain.

Coil Treatment
After cleaning, we apply a coil treatment that slows re-fouling. In Koreatown’s grease-heavy air, untreated coils re-coat within months. The treatment isn’t a miracle; it’s a surface modifier that makes the next cleaning easier and extends the interval. Coil treatment is included in most full HVAC cleaning packages for Koreatown customers, and we’ll tell you honestly whether your system needs it or whether a plain cleaning is enough. We don’t upsell what the coil doesn’t need.

AfterTrusted Brands We Service in Koreatown
Koreatown’s older buildings run everything from original galvanized ductwork to modern flex systems, and the equipment varies just as widely. We service and clean units from Honeywell, Aprilaire, and Abatement Technologies, among others, and our crews carry the fittings and cleaning tools specific to each brand’s coil geometry. If your building has a Honeywell media cabinet or an Aprilaire humidifier attached to the handler, we clean those as part of the system, not as a separate line item tacked on after the fact. You can look up any brand we name; we don’t clean with equipment we wouldn’t put our own name on.
Common HVAC Cleaning Problems We See in Koreatown Homes

- Grease-saturated coils from BBQ exhaust. This is the Koreatown signature. Rooftop intakes pull airborne grease from nearby grill operations, and the evaporator coil turns it into a sticky, odor-trapping film. Residents smell BBQ in their apartment without ever grilling at home.
- Corroded galvanized ducts in pre-1980 buildings. Moisture from proximity to marine air and the constant cooling load on aging systems causes condensation inside original galvanized duct runs. That condensation collects dust, corrodes the metal, and leaks into unit chases.
- Cross-unit contamination through shared duct chases. Many Koreatown apartment buildings route multiple units’ ductwork through common chases. When a chase isn’t sealed, one unit’s cooking odors, bathroom exhaust, or microbial growth can migrate into a neighbor’s supply air. We find this on a regular basis.
- Blower wheels packed with carbon and tire-rubber dust. The I-10 and US-101 put freeway particulate into the air at ground level, and rooftop intakes don’t filter it all out. Blower wheels in Koreatown units we’ve opened often carry a dense, dark deposit that reduces airflow and strains the motor.
Pricing for HVAC Cleaning in Koreatown, CA
A full HVAC cleaning for a typical Koreatown apartment or condo runs $450 to $750. That includes the evaporator coil, blower, air handler interior, drain pan, and accessible duct runs, with the documented photo record included as a standard deliverable. Smaller scopes, like a standalone condenser cleaning, run $120 to $220. If your building’s access is unusually difficult, such as a rooftop unit reachable only by ladder with no catwalk, expect the quote to land on the higher end. You’ll get a written price before any work starts, under Haven Standard Clause 1. That price is the price; we don’t discover surprises halfway through the job.

FAQs - HVAC Cleaning in Koreatown

The smell comes from airborne grease and smoke from the neighborhood’s dense concentration of Korean BBQ restaurants. Your rooftop or window HVAC intake pulls that exhaust-laden air into your system, where the evaporator coil condenses the grease into a sticky film that holds the odor. Cleaning the coil and duct runs with negative-pressure extraction removes the source of the smell. Fogging a sanitizer on top of that film does not. Call (806) 606-6902 for a written quote on source removal.
Koreatown’s grease and freeway particulate load means most systems here need cleaning every 2 to 3 years, compared to 3 to 5 years for coastal neighborhoods with cleaner air. If you live within a block of a high-volume BBQ restaurant on Wilshire or Western, check your coil yearly and plan to clean at the two-year mark. We’ll photograph the coil and tell you honestly whether it’s time or whether you have another year.
Yes, and we find it in specific places: the evaporator coil, the drain pan, and the inside of uninsulated duct runs in pre-1980 buildings. Koreatown sits far enough inland to avoid daily marine-layer fog, but summer humidity still condenses on cold coil surfaces, and when that moisture combines with organic dust in the ducts, microbial growth follows. A source-removal clean removes the organic material. A fogging sanitizer alone leaves the food source behind and the problem returns.
Source removal means physically removing the contamination: grease film, dust, debris, and any visible microbial growth, using negative-pressure extraction and HEPA-filtered agitation tools. A fogging sanitizer is spraying a chemical mist into the ducts, which kills surface microbes but leaves the material they were living on in place. In Koreatown, where the contaminant is often a thick grease film, fogging without source removal is a waste of money. We do source removal and photograph every duct run before and after, so you see the material that left the building.
Yes, many 1940s-to-1970s Koreatown buildings route ductwork from multiple units through common chases, and those chases are often not sealed at the unit boundary. When that’s the case, cooking odors, bathroom exhaust, and microbial spores can move from one apartment into another’s supply air. We check for chase leakage during HVAC cleaning and can seal accessible gaps. It’s not a problem every building has, but it’s common enough in this housing stock that we look for it on every Koreatown job. Call (806) 606-6902 for an inspection and written quote.
