Fast, Reliable Air Duct Cleaning Across Los Angeles
Air duct cleaning in Los Angeles typically runs $350–$850 for residential systems and is usually completed in a single visit by our owner-led crew. We’re based in Bell, CA, and we make the drive up the I-110 or I-5 to reach Los Angeles properties with same-day scheduling when the job’s urgent. Richard Anderson, our owner and lead technician, personally handles every Los Angeles call — you’ll never get a subcontractor you’ve never met.

Los Angeles isn’t a generic market for us. We’ve spent 14 years working in the basin’s unique conditions: wildfire smoke seasons that load fine ash into duct systems, retrofit ductwork in 1920s bungalows that wasn’t designed for modern airflow, and — on the rural acreage properties in the northern Valley and hills — detached workshops with supply runs stretching 80 to 120 feet from the main house. Our Air Duct Cleaning team brings 100-foot hose reels, commercial-grade Rotobrush agitation systems, and the patience to do it right in one trip. Call (833) 958-5022 for a free estimate.
Why Landmark Air Duct Cleaning Service California Is Los Angeles’s Preferred Air Duct Cleaning Company
We’ve earned a 4.9-star average across 364+ verified reviews, and a growing share of those come from Los Angeles homeowners who found us after frustrating experiences with franchise crews. Richard Anderson shows up — not a rotating crew you’ve never met. That personal accountability matters especially on Los Angeles’s larger properties, where incomplete work means a second trip across the basin.
Our response time to Los Angeles averages 45–90 minutes from dispatch for scheduled appointments, and we prioritize emergency calls during wildfire smoke events when duct contamination spikes across the 90030, 90031, 90032, and 90033 ZIP codes. We know the local terrain: the tight attic spaces in Koreatown’s 1920s courtyard apartments, the rooftop package units serving multiple units along Vermont Avenue, and the sprawling Chatsworth acreage where a detached workshop’s duct run can exceed 100 feet.
Los Angeles customers specifically mention our thoroughness in reviews — the fact that we check return plenums for rodent debris, video-inspect before and after, and don’t rush through shared ductwork in multi-unit buildings where cross-contamination is a real risk. Fourteen years focused on one trade: cleaner air, cleaner ducts.
Our Air Duct Cleaning Services in Los Angeles
Residential Duct Cleaning
Los Angeles’s housing stock demands specialized knowledge. In the 90001–90010 ZIP codes — South LA, Koreatown, Mid-City — we regularly encounter bungalows and post-WWII apartment buildings where central HVAC was retrofitted decades after construction. Flexible duct runs through attics that hit 140°F in August degrade faster here than in purpose-built systems. Our Rotobrush system agitates embedded particulates without damaging compromised liner, and we seal accessible joints with mastic rated for those temperature swings. A typical residential duct cleaning in Los Angeles runs $350–$650 for a single-family home, $450–$850 for multi-unit buildings with shared plenums.
Commercial Duct Cleaning
Commercial properties in Los Angeles face intensified loading from the basin’s trapped particulates — the ring of San Gabriel, Santa Monica, and San Gabriel mountains holds wildfire smoke, I-10 and I-110 corridor exhaust, and industrial aerosols directly over the metro. We service small commercial buildings, retail spaces, and professional offices with Nikro negative-air extraction systems that maintain containment during cleaning. For properties near the freeway corridors or in industrial transition zones, we recommend semi-annual service rather than annual — the particulate load justifies it. Commercial duct cleaning in Los Angeles typically ranges $800–$2,500 depending on system size and contamination level.
Supply Duct Cleaning
Supply ducts push conditioned air into your living spaces — and in Los Angeles, they’re delivering more than temperature-controlled air. Fine particulates from wildfire events, tire rubber dust from the 110 freeway, and smog aerosols stay suspended in our near-zero humidity rather than clumping and settling. That means supply ducts accumulate a finer, more deeply embedded contamination layer that standard vacuuming won’t touch. Our supply duct service uses Rotobrush rotary agitation followed by Nikro negative-air extraction, with video inspection to verify clear runs. On rural Los Angeles properties with detached workshops, we bring 100-foot hose reels to reach supply branches that standard 50-foot equipment can’t — eliminating the multiple trips that frustrate busy homeowners.
Return Duct Cleaning
Return ducts pull air back to the HVAC unit, and in Los Angeles’s dense apartment corridors — particularly Koreatown’s 6th Street and Vermont Avenue buildings — they’re where cross-contamination happens. A rodent intrusion or cockroach debris in one unit’s return can distribute through shared plenums serving four to eight units. We inspect return plenums with video scopes, clean with targeted agitation, and apply Guardsman UV treatment where microbial contamination is present. For single-family homes in Los Angeles, return duct cleaning is typically bundled with supply cleaning; standalone return service runs $200–$400.

Trusted Brands We Service in Los Angeles
We maintain direct working knowledge of Honeywell, Aprilaire, and Abatement Technologies systems — the brands we encounter most frequently in Los Angeles’s residential and light-commercial installations. Richard Anderson stocks common replacement components for these manufacturers on our service vehicles, which means faster turnaround when we find a failed damper, degraded filter housing, or compromised UV bulb during cleaning. We don’t sell equipment we can’t service, and we don’t service brands we don’t understand. For Los Angeles customers with older retrofit systems — common in the 1920s–1950s housing stock — this parts-ready approach prevents the “we’ll have to order that and come back” delay that turns a single visit into a multi-week project.
Common Air Duct Cleaning Problems We See in Los Angeles Homes
- Wildfire ash embedding in fine-particle layers. After major fire events in the surrounding hills and canyons — recurring in this region — duct systems throughout the Los Angeles basin accumulate fine ash and combustion particles even miles from the fire perimeter. The basin topography traps these particulates, and our near-zero humidity keeps them suspended and recirculating rather than settling. Standard cleaning often misses this layer; rotary agitation is necessary.
- Retrofit ductwork in pre-HVAC housing stock. The bungalows and post-WWII apartment buildings dominating South LA, Koreatown, and Mid-City were never designed for central air. Flexible duct run through 140°F attics degrades faster than in purpose-built systems, with liner breakdown creating additional particulate sources and air leaks that load the system with attic dust.
- Shared plenum cross-contamination in multi-unit buildings. Rooftop package units serving four to eight units through common-wall ductwork mean one unit’s rodent intrusion or pest debris distributes building-wide. Technicians accustomed to single-family work often miss this pattern entirely — we inspect the full plenum, not just the accessible branches.
- Inadequate equipment reach on rural acreage properties. Standard 50-foot hoses can’t cross large lots to reach detached workshops with independent supply runs. Crews either skip the outbuilding or force a rebooking. We bring 100-foot reels and plan the route before arriving — one trip, complete cleaning.

What moves you within these ranges? System size matters — a 2,000 sq ft home with 12 supply registers costs less than a 4,500 sq ft property with 28 registers and a detached workshop. Contamination level matters — wildfire ash events or long-deferred maintenance require more agitation time and disposal care. Accessibility matters — crawl space ductwork in older Los Angeles foundations takes longer than attic runs with proper access hatches. We don’t quote blind. Richard Anderson inspects your system, explains what he finds, and gives you a fixed price before starting work. Estimates are free. Call (833) 958-5022.

FAQs — Air Duct Cleaning in Los Angeles
We bring 100-foot hose reels and plan the route before arrival, so we can clean main-house ducts and outbuilding supply runs in a single visit. Standard crews often show up with 50-foot equipment that can’t reach across large lots, forcing rebooks or incomplete work. We serviced a 4,200 sq ft custom home on a 2-acre lot near Chatsworth, with a detached workshop sporting a 16-ft insulated door and heavy-duty LiftMaster operator. The homeowner wanted the duct system cleaned in one trip because his schedule was tight. We used our Rotobrush system with a 100-ft hose reel to reach the workshop’s supply runs, and applied Guardsman UV light to the return grilles—all in a single visit, no rebook. Call (833) 958-5022 to schedule — we’ll confirm your lot layout when you book.
Rural Los Angeles properties still accumulate dust from unpaved access roads, agricultural drift from the Valley, and pollen from the chaparral hillsides — plus the same basin-trapped smog aerosols that affect the entire metro. Your workshop’s duct system also draws in welding fumes, sawdust, or automotive exhaust if it’s actively used, and recirculates those particles through connected supply runs. Even without wildfire events, these loading factors degrade indoor air quality and HVAC efficiency. Call (833) 958-5022 for an inspection — estimates are free.
We don’t clean through door mechanisms — we access ductwork through designated supply and return registers, or through service openings in the plenum. However, we do inspect and lubricate heavy-duty torsion springs on shop doors as part of our comprehensive service, since binding springs can compromise the door seal and allow unfiltered air into the workshop space. This is a detail many crews overlook, leading to callbacks for door issues that weren’t part of the original complaint. Richard Anderson handles this personally on every rural property call. Call (833) 958-5022 to discuss your shop setup.
We confirm your property layout when you book — lot size, workshop location, register count, and any access constraints. Richard Anderson loads the appropriate hose length, brush diameter, and UV equipment before leaving Bell. We’ve learned that “we’ll figure it out when we get there” is how other crews turn one appointment into two. Our 14 years of Los Angeles-area work means we know which properties need extended reach, which have rooftop package units requiring ladder access, and which older foundations have crawl space entries that need specific clearances. One trip is our standard, not our exception. Call (833) 958-5022 to book with confidence.
Intermittently used spaces often need cleaning more, not less — stagnant air allows particulates to settle and consolidate, and temperature swings between active and idle periods stress duct liners and create additional debris. In Los Angeles’s dry climate, that settled dust doesn’t clump and stay put; it re-enters circulation the moment the system restarts. If your shop connects to the main house duct system, contamination migrates regardless of how often you use the workshop. A typical detached workshop cleaning in Los Angeles runs $200–$400 when bundled with main-house service. Call (833) 958-5022 for an exact quote — estimates are free.
