Fast, Reliable HVAC Cleaning Across Los Angeles
Professional HVAC cleaning in Los Angeles typically costs between $350 and $850 for a full system service, with most jobs completed in a single visit by our background-checked, uniformed technicians. We answer calls live, 24 hours a day, and we serve Los Angeles homeowners from our local base - reaching neighborhoods from Koreatown to Woodland Hills without the delays of out-of-town operators.
We’ve been cleaning HVAC systems in Los Angeles since 2012, and we’ve learned what the basin’s unique conditions do to ductwork. The combination of chronic smog, annual wildfire smoke, and Santa Ana wind events creates a contamination cycle you won’t find in San Diego or Riverside. Our HVAC Cleaning team treats the specific problems Los Angeles homes face, not generic dust buildup. If your system is circulating fine particulates, struggling with airflow, or running longer cycles than it used to, call us at (844) 685-6342 for a free estimate.
Why Bellows Air Duct & Vent Co. Is Los Angeles’s Preferred HVAC Cleaning Company
Ray Castillo has led Bellows Air Duct & Vent Co. since its founding in 1984, building our reputation on one principle: the job is done right, or we return and make it right - no paperwork, no arguing. That 90-Day Done Right Promise is stamped on every invoice we write in Los Angeles, and we’ve honored it for more than four decades.
Our technicians are background-checked and uniformed on every job, every time. They carry professional-grade equipment from Rotobrush, Nikro, and Abatement Technologies - the same brands serious HVAC contractors specify for commercial installations. Before we lift a single tool, we show you one honest price. The number on the phone is the number on the invoice. No bait coupons, no price changes at the door.
We answer our phones with a live person, 24/7. Not voicemail. Not an app. Los Angeles homeowners who’ve been burned by discount operators tell us this matters more than anything. When the Santa Ana winds are blasting desert dust through your vents or wildfire ash has settled in your returns, you reach a human who can dispatch a crew.
Most Los Angeles jobs finish in one visit. We camera-inspect ductwork before and after every clean, so you see the condition we found and the results we delivered. That visual record is yours to keep.
Our HVAC Cleaning Services in Los Angeles
Evaporator Coil Cleaning
The evaporator coil in your Los Angeles air handler works harder than it should. The basin’s thermal inversion layer traps vehicle exhaust and industrial PM2.5 at breathing level year-round, and that particulate loads onto wet coil surfaces, forming a dense mat that cuts airflow and forces your compressor to run longer cycles. In retrofitted Valley homes with aging flex duct, that coil often hasn’t been accessed in twenty years. We remove the housing, apply foaming cleaner, and inspect with a borescope. A typical evaporator coil cleaning in Los Angeles runs $180-$340. Coil treatment with a protective surfactant adds $45-$85 and extends the interval between services.
Air Handler Cleaning
Los Angeles air handlers collect what the city’s air delivers. In 1950s-1970s stucco tract homes across Van Nuys, Reseda, and Northridge, these units were often installed in attic or garage spaces with minimal filtration and sealed only recently against Santa Ana intrusions. We disassemble the cabinet, clean the blower wheel, motor housing, and drain pan, then verify airflow with a manometer. Air handler cleaning in Los Angeles typically costs $280-$480 depending on access difficulty and contamination level. Older installations in tight attic spaces take longer - we tell you before we start.
Blower Cleaning
A blower wheel caked with Los Angeles particulate can’t move design airflow. You’ll feel it as weak vents, hot second floors, or a system that never reaches thermostat setpoint. We remove the blower assembly, clean each vane with compressed air and solvent, balance the wheel, and reinstall. Blower cleaning alone runs $150-$280 in the Los Angeles market. Combined with evaporator service, the package typically totals $320-$520. We show you the before-and-after camera footage so you see why the difference matters.
Condenser Cleaning
Your outdoor condenser coil breathes the same dirty air. In Los Angeles, cottonwood fluff from the LA River corridor, wildfire ash fallout, and plain dust from unpaved hillside lots clog fin arrays and raise head pressure. We chemically clean the coils, straighten damaged fins, and verify refrigerant pressures. Condenser cleaning in Los Angeles averages $120-$220 as a standalone service, or $80-$150 when bundled with indoor work.

Common HVAC Cleaning Problems We See in Los Angeles Homes
- Smoke ash from annual wildfires clogs ducts rapidly. After events like the 2018 Woolsey Fire or 2025 Palisades/Eaton fires, we find filter media and duct debris testing positive for wood-combustion ash. This fine particulate passes standard filters and distributes throughout living spaces, reducing airflow and forcing longer run times.
- Santa Ana wind events blast desert dust and ash through unsealed duct penetrations. The fall Santa Ana winds push additional particulate directly into return-air intakes, overwhelming standard filter media within days. Homeowners in the valleys and foothill communities see the worst infiltration.
- Older flex duct or ductboard in retrofitted homes holds decades of accumulated particulate. The 1950s-1970s stucco tract homes across the San Fernando Valley and South Bay were originally built with evaporative coolers or no central air, with forced-air systems added later through attics and crawl spaces. That aging, often unsealed flex duct has never been professionally cleaned.
- Low humidity means mold is rare, but dry-climate dust accumulation is exceptionally heavy. Unlike humid coastal cities where mold drives cleaning schedules, Los Angeles systems accumulate concentrated mineral dust, ash, and urban particulate that standard residential vacuums fail to fully extract.

FAQs - HVAC Cleaning in Los Angeles
Schedule a full HVAC cleaning within two to four weeks of any major wildfire event affecting your area, and replace filter media immediately if you smell smoke or see ash accumulation on registers. In Los Angeles, where the annual wildfire season deposits combustion byproducts across the basin, we recommend annual cleaning for homes in valley and foothill communities, and biennial service for coastal areas with less direct smoke exposure. Call (844) 685-6342 to schedule - estimates are free, and we prioritize post-fire appointments.
Duct cleaning removes the particulate source of smoke odor, but persistent odor usually requires combined duct cleaning plus coil treatment and antimicrobial application to the air handler. After the 2025 Palisades Fire, our crew serviced a 1960s stucco tract home in Woodland Hills where Santa Ana winds had forced smoke ash through unsealed attic ductwork. We removed decades of urban particulate and combustion byproducts from the aging flex ducts, then applied a coil treatment to the evaporator to restore airflow. The odor resolved because we treated the full contamination path, not just the visible ducts. For severe cases near structure fires, we may recommend duct sealing or replacement of heavily contaminated flex runs. Call (844) 685-6342 for an inspection.
Yes, with proper inspection and technique. Most Van Nuys tract homes from this era have flex duct or ductboard retrofitted through attic spaces, and our camera inspection reveals condition before we commit to cleaning. We look for brittle ductboard, disconnected flex runs, and unsealed penetrations that Santa Ana winds have exploited for decades. Where ductwork is too degraded, we show you the camera footage and quote repair or sealing before proceeding - we do not force high-pressure air through damaged ducts. The cleaning itself uses controlled negative pressure and rotary brushes sized to the duct diameter. Call (844) 685-6342 for a camera inspection - estimates are free.
Switch your thermostat to “fan off” rather than “auto” to reduce intake volume, replace your filter immediately after the event ends, and inspect outdoor condenser coils for visible dust loading. The Santa Ana winds push desert particulate and wildfire smoke directly into return-air intakes across Los Angeles, and running your system continuously during peak events accelerates contamination. If you smell dust or see reduced airflow after the winds subside, schedule a cleaning within two weeks - the particulate sets into coil surfaces and becomes harder to remove. Call (844) 685-6342 for priority scheduling after major wind events.
Yes - mold growth in ducts is rare in Los Angeles due to the region’s arid climate, which is why we focus on dry-climate dust, ash, and urban particulate rather than moisture-driven contamination. The tradeoff is that this same low humidity allows fine particulate to accumulate in dense, concentrated layers that standard filters miss. Your Los Angeles system is continuously filtering some of the dirtiest ambient air in the country, and without mold to signal a problem, that accumulation often goes unnoticed until airflow drops or energy bills spike. We recommend camera inspection every two to three years to catch buildup before it stresses your equipment. Call (844) 685-6342 to schedule - estimates are free.
