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.

AfterLennox Air Duct Cleaning in Los Angeles, CA | Kestrel Air Duct Cleaning
We’re Kestrel Air Duct Cleaning - Los Angeles, and we handle independent Lennox air duct cleaning across the basin. The short answer: if you own a Lennox Merit, Elite, or Signature Series system in this basin, your ducts are pulling in more wildfire ash and fine particulate than almost anywhere else in the country, and that changes both when you clean and how you clean. We know Lennox ducted architecture inside and out - flexible and rigid trunk designs, high-static ECM blowers, sealed combustion configurations - and we’re not affiliated with Lennox, authorized by them, or endorsed by them. We just work on their equipment every day. Call (469) 972-3151 for a free estimate with a written price before any work begins.
Why Los Angeles Residents Choose Us for Lennox Service
Most duct cleaning companies in Los Angeles treat a Lennox system like any other forced-air setup. That’s a mistake. Lennox runs high-static ECM blowers on many of their residential lines - the Merit ML180, the Elite EL296, the Signature SLP98 - and those blowers move air differently than single-speed PSC motors. They compensate for dirty filters by ramping up static pressure, which means a partially clogged coil or blower wheel on a Lennox system can keep delivering air while silently forcing more particulate through every crack and seam. By the time the homeowner notices uneven cooling or a dusty register, the contamination is often throughout the entire duct run.
Dale Whitmore, our owner, grew up in the San Fernando Valley and trained formally at Los Angeles Trade-Technical College. He’s been cleaning ducts across Los Angeles for more than a decade, and he’s seen what a 1960s ranch attic at 140°F does to fiberglass flex liner - which is why we also offer our Dryer Vent Cleaning in Los Angeles for complete home safety. We approach every Lennox job with that local knowledge, and we carry high-temperature-rated flex duct, blower wheels, and filter media that meet or exceed Lennox specifications. It means faster turnaround and a repair that holds up under valley attic conditions. We also use the right tools: Rotobrush rotary brush systems to break debris loose at the duct wall, Nikro negative-pressure units to pull it out, and Abatement Technologies HEPA filtration so the loosened particulate doesn’t end up on your sofa.
Common Lennox Air Duct Cleaning Problems We Solve in Los Angeles
- Wildfire ash baked onto evaporator coils and blower wheels. After the Woolsey, Creek, and Eaton fires, the basin’s thermal inversion layer trapped smoke at ground level for days. Lennox systems ran continuously during those periods, pulling fine ash and VOCs directly onto coil fins and into blower cages. The symptom reads like a refrigerant issue - uneven cooling, longer runtimes - but the cause is often airflow restriction, not a leak.
- Collapsed fiberglass flex duct liner in valley attics. San Fernando Valley summers push attic temperatures past 140°F. Original flex duct from a 1960s or 1970s Lennox installation breaks down under that heat, the inner liner collapses, and debris feeds straight into the air handler. We see this in single-story ranch homes from Reseda to Chatsworth, and it often clogs the secondary heat exchanger on Lennox 80% and 96% furnaces.
- Pre-1978 rigid duct with asbestos-containing wrap. Eastside neighborhoods like Highland Park, and older Mid-Wilshire tracts, are full of Lennox systems installed when rigid ducts came wrapped in asbestos insulation. We won’t touch that wrap. Any cleaning job on a pre-1978 Los Angeles home with suspected asbestos requires a licensed abatement evaluation first, and we’ll tell you that straight before anyone moves a register.
- Dry dust buildup on supply registers and return chases. Los Angeles’s near-zero humidity means no natural moisture flushing. Dust that would wash out in a humid climate just keeps accumulating. After a fire event, even homes miles from the hills - Culver City, Pasadena, downwind flatland ZIP codes - show visible ash on Lennox supply registers within weeks.
- Burning smell from a contaminated blower wheel. A Lennox blower cage caked with fine particulate will smell like an electrical fault, especially on the first hot day. It’s not the motor. It’s the wheel forcing overheated air across layers of fine ash and dust. Cleaning the blower - not replacing it - resolves the odor in most cases we see.
Lennox Service in Los Angeles: What Local Conditions Mean for Your Equipment
Here’s a fact about Los Angeles you won’t find on a generic duct cleaning page: the basin’s persistent thermal inversion layer doesn’t just trap smog. It traps wildfire smoke and fine ash at respirable altitude for days at a time. That means a Lennox system in Culver City can pull in particulate from a fire burning in the Angeles National Forest, or the Pacific Palisades, or the hills above Altadena - none of which are anywhere near the house. After the Eaton Fire in early 2025, our crew was called to a 1962 ranch home in Altadena with a Lennox Merit Series furnace and original fiberglass flex duct in a 145°F attic. The homeowner reported a burning smell and visible ash on the supply registers. Our video inspection found collapsed duct liner and a blower wheel coated with fine particulate. We cleaned the full system, repaired the flex runs with high-temperature duct, and cleaned the blower. Airflow returned, the smell disappeared, and the Lennox equipment never needed replacing. That’s not a one-off. It’s a predictable Los Angeles cycle, and it means duct cleaning here is tied to smoke events, not a fixed annual schedule.
Lennox Models & Products We Service in Los Angeles
We service the full residential Lennox range in Los Angeles. That means Merit Series products like the 14ACX, ML14XC1, and ML180; Elite Series equipment including the EL16XC1, EL280, and EL296; and the Dave Lennox Signature Collection, from the SL280 to the SLP98. We also work alongside Lennox Healthy Climate indoor air quality accessories - media filters, UV systems, HRVs and ERVs - since those often hold the key to keeping a freshly cleaned system clean. When a component needs replacing, we use OEM-equivalent or better aftermarket parts when they meet or exceed Lennox specifications, and we reserve OEM parts where fit or warranty concerns favor them. If the air handler or coil is heavily contaminated but mechanically sound, cleaning and sealing is often the smarter investment than replacement. If the heat exchanger or blower motor is compromised, we’ll explain the trade-offs without pushing a sale.
Lennox Service Pricing in Los Angeles
Most Lennox duct cleaning jobs in Los Angeles run between $400 and $900 for a full system, depending on home size, duct configuration, and contamination level. A single-story valley ranch with accessible flex duct lands toward the lower end. A two-story Mid-Wilshire home with rigid duct and 20 years of particulate buildup lands higher. Blower cleaning and video inspection are included in a full system cleaning, not tacked on as upsells. What drives cost most in Los Angeles is what’s in the ducts, not square footage. Wildfire ash, renovation dust, and decades of dry accumulation all take longer to extract thoroughly. Every estimate is free, and the written price is in your hands before a single vent is touched. Call (469) 972-3151 for an exact quote.

FAQs - Lennox Air Duct Cleaning in Los Angeles
In Los Angeles, wildfire smoke events are now nearly year-round, and the basin’s inversion layer traps that particulate for days. A Lennox system running during a fire event pulls fine ash into the coil, blower, and entire duct run. We recommend cleaning after any major smoke event that produces visible ash or a persistent odor, rather than on a fixed annual schedule. For most Los Angeles homes, that means every 2 to 4 years depending on how close you are to burn zones and whether your home has been through nearby construction. Call (469) 972-3151 and we’ll walk you through what your situation calls for.
Watch for reduced airflow through specific rooms, visible dust around supply registers, and any rumbling or flapping sound when the blower runs. In Valley attics that regularly exceed 140°F, original fiberglass flex duct liner degrades, collapses, and sheds debris into the Lennox air handler. If your home is a 1950s-1970s ranch that’s never had the flex replaced, assume it’s near end-of-life. Video inspection will confirm it, and high-temperature-rated flex duct is the fix we use most often.
Not without an asbestos evaluation first. Pre-1978 homes across the Eastside, Mid-Wilshire, and older Valley tracts often have rigid ducts wrapped in asbestos-containing material. We won’t disturb that wrap. If asbestos is present or suspected, a licensed abatement specialist must evaluate before any cleaning. If you’re unsure about your home, tell us the year it was built and the age of the ducts. We’ll advise you honestly before anyone schedules a visit.
Because fine ash and smoke particulate are still sitting in the ductwork, often baked onto the evaporator coil and blower wheel from weeks of exposure during the fire event. Los Angeles’s dry air doesn’t flush it out - it accumulates. The odor returns every time the system runs, and it won’t go away with a filter change. Full system cleaning, including blower cleaning, removes the source rather than masking it. Call (469) 972-3151 for a free estimate, and we’ll inspect before quoting a price.
We use OEM-equivalent or better aftermarket components when they meet or exceed Lennox specifications. That covers high-efficiency filter media, blower wheels, and flex duct rated for high-temperature attic installation. Where fit or warranty considerations favor OEM parts, we use OEM parts. No hidden preference, no “we only use factory” line that quietly limits your options. We’ll tell you what’s going in and why, in writing, before work starts.
