Fast, Reliable Air Duct Cleaning Across Los Angeles
Air duct cleaning in Los Angeles typically runs $350-$850 for a full residential system, with most jobs completed in a single visit. We’re Bellows Air Duct & Vent Co., and we’ve been cleaning ductwork across Los Angeles since 1984. Our Air Duct Cleaning team knows the difference between a standard dust removal and the heavy-duty ash and particulate cleanup that LA’s wildfire seasons demand. We answer calls live, 24 hours a day, at (844) 685-6342.
Los Angeles sits in the most ozone- and particulate-polluted air basin in the United States. The annual wildfire season - producing events like the 2018 Woolsey Fire and 2025 Palisades/Eaton fires - deposits fine smoke ash and combustion byproducts directly into ductwork across vast swaths of the metro. Fall Santa Ana wind events blast desert dust and ash through any unsealed duct penetration. LA homeowners face a duct-contamination cycle driven by wildfire smoke and chronic smog infiltration, not just ordinary household dust. That’s a problem largely absent in neighboring cities like San Diego or Riverside, and it’s why we approach Los Angeles jobs differently.
We serve homes from Koreatown to Echo Park, Silver Lake to Florence-Graham, and up into the foothill communities where smoke infiltration hits hardest. Our technicians arrive in uniform, background-checked, with Rotobrush and HEPA-filtered equipment on every truck. Most jobs finish in one trip. We’ll be there when we say.
Why Bellows Air Duct & Vent Co. Is Los Angeles’s Preferred Air Duct Cleaning Company
We’ve built our reputation in Los Angeles over 42 years by doing what we say we’ll do. Ray Castillo leads this company with a simple standard: the job isn’t done until the homeowner sees the before-and-after camera footage and signs off on it. No paperwork games, no arguing - our 90-Day Done Right Promise means we return at no charge if anything’s not right.
Our Los Angeles customers call us back because we show one honest price before lifting a single tool. No bait coupons, no price changes at the door. The number on the phone is the number on the invoice. We’ve seen too many LA homeowners burned by low-bid operators who upsell once they’re inside the house. That’s not how we work.
Calls are answered by a live person, 24/7. Not a voicemail tree, not an app. When Santa Ana winds kick up and your return vents start blowing dust, you want someone who picks up. Our response time to most Los Angeles neighborhoods is same-day or next-day, with emergency scheduling available for post-wildfire contamination.
We know the local housing stock. A dominant share of LA’s residential inventory consists of 1950s-1970s stucco tract homes across the San Fernando Valley, South Bay, and East LA - originally built with evaporative coolers or no central air, with forced-air HVAC retrofitted later through attics and crawl spaces. That means aging, often unsealed flex duct or ductboard that has accumulated decades of particulate without professional cleaning. We clean it properly because we’ve seen it hundreds of times.
Our Air Duct Cleaning Services in Los Angeles
Residential Duct Cleaning
Most Los Angeles homes we service haven’t had their ducts cleaned in twenty years or more. That’s not a guess - we hear it directly from homeowners in Woodland Hills, Highland Park, and throughout the Valley. Our residential cleaning covers the full supply and return network, registers, grilles, and the air handler cabinet. We use Rotobrush agitation with HEPA vacuum containment, then video-inspect every branch so you see what came out. A typical residential duct cleaning in Los Angeles runs $350-$650 for a single-system home.
Commercial Duct Cleaning
Los Angeles commercial buildings face the same smog and wildfire ash load as residences, often with more complex rooftop package units and longer duct runs. We clean office HVAC systems, retail spaces, and multi-tenant buildings across the metro. Commercial jobs are priced by system size and access - most small-to-mid commercial cleanings in Los Angeles fall between $800-$2,400. We work around your hours to avoid disrupting operations.
Supply Duct Cleaning
Supply ducts push conditioned air into your living spaces. In Los Angeles, these lines often run through hot attics where flex duct degrades and tears, pulling in insulation fibers and attic dust along with the outdoor particulate load. We clean supply branches individually, seal accessible leaks with mastic, and flag any ductwork that needs repair before it gets worse. Supply-only cleaning in Los Angeles typically ranges $250-$450 when done as a standalone service.
Return Duct Cleaning
Return ducts draw air back to the HVAC unit for reconditioning. They’re your home’s primary intake point for outdoor contaminants - LA smog, wildfire ash, Santa Ana dust. Return trunks and plenums accumulate the heaviest debris loads. We clean returns with negative air machines and rotary brushes, then inspect the filter rack for proper sealing. Return-only cleaning in Los Angeles generally runs $200-$400.
Full System Cleaning
This is our most thorough service and the one we recommend for most Los Angeles homes, especially after wildfire exposure or for first-time cleanings on mid-century properties. Full system cleaning covers supply ducts, return ducts, registers, grilles, blower assembly, evaporator coil (if accessible), and the air handler cabinet. We HEPA-vacuum all components, agitate debris with Rotobrush equipment, and provide complete before-and-after video documentation. Full system cleaning in Los Angeles typically costs $550-$850 for residential properties.
Video Inspection
Every Bellows job includes camera inspection before and after cleaning - not as an upsell, but as standard practice. In Los Angeles, this matters more than most places. We’ve found burned building materials in ducts after structure fires, deteriorated flex duct chewed by roof rats common to LA’s older neighborhoods, and unsealed connections dumping attic air into living spaces for decades. You see what we see. No claims without proof.

Trusted Brands We Service in Los Angeles
We clean and service ductwork connected to all major HVAC brands, and we stock common replacement parts from Aprilaire and Abatement Technologies for fast turnaround on repairs and upgrades found during cleaning. Our technicians carry Rotobrush cleaning equipment on every truck - the same brand serious HVAC contractors specify for residential duct maintenance. For homes with integrated air quality systems, we service Aprilaire media cleaners and Honeywell electronic air cleaners, and we can source Guardsman UV-C sanitizer lamps where bacterial or mold concerns exist (though LA’s dry climate makes mold rare). Parts availability means most Los Angeles jobs that need a small repair during cleaning get finished that same day, not rescheduled for a parts run.
Common Air Duct Cleaning Problems We See in Los Angeles Homes
- Wildfire ash contamination in retrofitted attic ductwork. After the 2025 Palisades and Eaton fires, thousands of LA homes in the foothills had ductwork contaminated with heavy-metal particulates from burned structures. Standard residential cleaning without HEPA-filtered negative air machines spreads this debris rather than containing it. We use Abatement Technologies portable HEPA units and sealed disposal for fire-affected jobs.
- Decades of accumulation in unsealed flex duct from 1960s-1970s HVAC retrofits. The San Fernando Valley and South Bay are full of stucco tract homes where original evaporative coolers were ripped out and forced-air systems shoved through attics with minimal sealing. Dust, ash, and insulation pack into sagging flex runs. We find ductboard that’s never been opened since installation.
- Smog particulate baked into duct interiors by LA’s thermal inversion cycle. The basin traps vehicle exhaust and industrial PM2.5 at breathing level year-round. HVAC systems continuously filter this dirty ambient air, and fine particulate embeds in duct walls over time. Wet-vacuuming turns this dry-climate dust to mud; we use controlled agitation and HEPA extraction instead.
- Return-air intakes pulling Santa Ana dust and unfiltered outdoor debris. During Red Flag conditions, high winds force particulate through poorly sealed return plenums and filter bypass gaps. We inspect and seal these penetration points as part of every full system cleaning.

FAQs - Air Duct Cleaning in Los Angeles
Yes. Fine wildfire ash and combustion particulates infiltrate ductwork through return-air intakes, outdoor unit cabinets, and any unsealed penetration - even when indoor air seemed clear. After the 2025 Palisades and Eaton fires, we cleaned ducts in homes where owners reported no visible smoke, yet our pre-cleaning video showed heavy ash loading in return plenums. The LA Basin’s thermal inversion layer keeps these particulates circulating at ground level for days after active burning ends. Call (844) 685-6342 for a free post-fire inspection.
Debris from homes near structure fires requires sealed containment and disposal at licensed facilities, not standard residential waste. We use Abatement Technologies HEPA-filtered negative air machines during cleaning, bag debris in sealed containers, and document disposal for fire-affected properties. This is standard on our post-wildfire jobs, not an extra charge. Standard household dust goes to normal waste; ash with potential heavy-metal content from burned building materials does not.
Valley homeowners should schedule full system cleaning every 2-3 years, with return-trunk inspection annually during HVAC tune-up. Santa Ana wind events blast fine desert dust through unsealed ductwork, and the Valley’s density of 1950s-1970s retrofitted systems means more accumulation points than newer construction. After any major wildfire event affecting LA County, schedule inspection regardless of elapsed time. Our $89 seasonal tune-up includes a basic duct-trunk visual check.
Cleaning removes embedded particulate that holds and re-emits ozone and VOC odors, but it won’t eliminate fresh smog infiltration if your system lacks proper filtration. We find that LA homes with standard 1-inch fiberglass filters get the most odor benefit from cleaning plus an upgrade to pleated media or electronic air cleaning. After cleaning, the duct system no longer acts as a reservoir for years of trapped exhaust particulate. For persistent high-ozone days, we also inspect filter sealing and return-air pathways for outdoor leakage.
It’s common. We regularly service mid-century stucco homes in Woodland Hills, Van Nuys, and East LA where the original 1960s or 1970s HVAC retrofit has run forty to fifty years without professional duct cleaning. The flex duct or ductboard installed in those retrofits was never designed as a permanent solution, yet it remains in place, packed with decades of dust, ash, and degraded insulation. Our video inspection usually shocks these homeowners - and then we clean it properly. Call (844) 685-6342 for a free estimate and see what you’re breathing.
