Los Angeles isn’t one housing market. It’s a dozen. Our techs clean ducts in 1920s Spanish bungalows near Echo Park, post-war Valley ranches in Van Nuys, and glass towers on Century Boulevard. That range matters because the ductwork changes everything: original unsealed metal, asbestos-wrapped flex from the 1960s, or modern engineered systems with shared ventilation. We don’t guess. We camera-inspect first, price in writing second, then clean by the book under The Garrison Standard.

Rural and semi-rural properties on LA’s fringes sit on unpaved roads and open land, so ducts load with road dust, pollen, and wildfire ash faster than the urban core. Many run separate outbuilding or guest-house systems on their own air handlers, which need cleaning on a different cycle than the main house. The combination of dirtier intake air, household wood heat, and longer service drives means a realistic cleaning interval is every 18 – 24 months for the main home and every 12 months for outbuildings. This is different from neighboring cities like Burbank or Glendale, where paved streets, no outbuildings, and no wood heat push the interval to 3 – 5 years.

Why Hollis Air Duct Cleaning Is Los Angeles’s Preferred Air Duct Cleaning Company

We’ve been part of the Garrison Partners family since 2004. In Los Angeles, that longevity means we’ve cleaned ducts through multiple wildfire seasons, including the Woolsey Fire in 2018 and the Palisades and Eaton Fires in 2025. We know what ash residue looks like in a return plenum. We know which Valley neighborhoods built between 1955 and 1975 are likely to have asbestos-wrapped ductwork that requires abatement referral before cleaning can proceed.

Our Los Angeles customers get the same standard every Garrison location follows: arrive inside the quoted window, price in writing before touching equipment, leave the site clean. No exceptions. The 365-Day Done Right Promise covers every job in writing. If the work fails within a year, we return and make it right at no charge, including a free second visit.

Phones are answered by a live person 24 hours a day, 7 days a week. No voicemail loops. No callback queues. Our technicians are background-checked and uniformed. You’ll know who’s arriving before they reach your door.

Commercial Air Duct Cleaning in Los Angeles

Commercial Air Duct Cleaning in Los Angeles covers office buildings, retail spaces, restaurants, and multi-unit properties where occupancy loads, kitchen grease, and shared ventilation systems create different contamination patterns than single-family homes. A typical commercial job in Los Angeles runs $500 – $1,500 depending on system size, access difficulty, and whether the building requires after-hours scheduling to avoid disrupting tenants or customers.

Multi-Tenant and High-Rise Systems

Downtown Los Angeles and Century City high-rises use engineered central air with complex shared duct networks. We coordinate with building engineers, work within HOA or management scheduling constraints, and document every stage for compliance records. Our Nikro negative-air machines maintain containment so one floor’s cleaning doesn’t redistribute debris to another.

Restaurant and Food-Service Ventilation

Kitchen exhaust and supply ducts in Los Angeles restaurants accumulate grease particulate that standard residential tools can’t address. We use Rotobrush rotary systems with appropriate agitation heads and HEPA filtration, then verify cleanliness with video inspection before signing off.

Air Duct Cleaning Services in Los Angeles

Air Duct Cleaning Services in Los Angeles include residential full-system cleaning, supply and return duct cleaning, video inspection, and duct sealing for homes from Santa Monica to the Inland Empire edges. A typical residential full-system cleaning in Los Angeles costs $300 – $800, with smaller condos or apartments starting around $250 and large homes with multiple zones reaching the upper end.

Supply and Return Duct Cleaning

Supply ducts push conditioned air into your rooms. Return ducts pull it back. In Los Angeles, return ducts are where we find wildfire ash, unpaved-road dust, and pollen concentrated. We clean both sides of the loop, not just the easy-access supplies, using source-removal methods with agitation and negative-air containment.

Video Inspection and Duct Sealing

Our camera systems show you the inside of your ductwork before and after cleaning. For rural properties near Topanga or Chatsworth, we also identify leaks at return boots that pull outdoor dust straight back in. We seal those leaks with mastic so the cleaning holds.

Trusted Brands We Service in Los Angeles

We maintain equipment from Rotobrush, Nikro, and Abatement Technologies, and we stock filtration products from Honeywell, Aprilaire, and Guardsman for Los Angeles customers who need replacement components after cleaning. Rotobrush rotary brush systems handle the mechanical agitation for residential ductwork. Nikro negative-air machines create the suction containment that keeps debris from escaping into your living space during cleaning. For homeowners upgrading filtration after a wildfire season, Aprilaire and Honeywell media filters fit most standard return grilles we encounter in Los Angeles homes. We carry common sizes on our vans to avoid a second trip.

Common Air Duct Cleaning Problems We See in Los Angeles Homes

• Asbestos-wrapped ductwork in 1950s – 60s Valley ranches. We camera-inspect before cleaning any home built between 1955 and 1975 in Van Nuys, North Hollywood, or Panorama City. If we find asbestos insulation, we stop and refer to a licensed abatement contractor. Cleaning over asbestos is illegal and hazardous.
• Wildfire ash infiltration through leaky returns. After the 2025 Palisades and Eaton Fires, we saw heavy ash loading in return plenums across the San Fernando Valley and foothill communities. The ash is fine enough to pass standard filters and settles in duct corners where standard household vacuums can’t reach.
• Unsealed return boots on rural properties. Homes off Agua Dulce Canyon Road or in Topanga pull fine brown road dust and oak pollen through gaps between the return grille and the duct boot. We seal with mastic during cleaning so the problem doesn’t recur in six months.
• Detached outbuilding air handlers skipped by other crews. A guest house or workshop on its own system is easy to overlook, especially when it’s 200 yards down a dirt driveway. We inventory every air handler on the property and price each system separately so nothing gets missed.
