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 | Linden Air Duct Cleaning
Air Duct Cleaning in Los Angeles for Lennox systems typically runs $450 to $950 for a full system, depending on the number of returns and how much wildfire ash and smog particulate has settled into the ductwork. We’re an independent Lennox service provider, not a manufacturer affiliate, and we’ve spent over a decade working on Lennox systems across Los Angeles, from post-war tract homes in Torrance to foothill neighborhoods like Altadena that sit directly under wildfire corridors. The thing that sets our Lennox work apart here: we know how LA’s specific air conditions, the Santa Ana dust, the inversion-layer smog, the ash events, interact with Lennox evaporator coils, blower wheels, and flex duct in ways a generalist never sees. Call us at (980) 447-2498 for a free estimate, and we’ll tell you honestly whether your ducts need cleaning, sealing, or something more.
Why Los Angeles Residents Choose Us for Lennox Service
We work on Lennox equipment daily. That’s not a slogan. The Dave Lennox Signature Collection, the Merit Series, the older Complete Heat systems, we’ve re-conditioned them in attics from Sylmar to Lakewood. Marcus Veale, our owner, grew up in the Crenshaw district and learned airflow diagnostics hands-on at the Los Angeles Trade-Technical College HVAC program. He’s been crawling through LA attics for more than ten years, and he’s the guy neighbors call when something smells off after a renovation or when the heat kicks on and the house smells like last October’s fire season.
What that means for you: we know the duct interfaces, coil cabinets, and control boards on Lennox equipment well enough to spot a restriction before it trips a limit switch. We carry OEM Lennox gaskets, filter racks, and coil cabinet seals, and when OEM stock is backordered we use high-quality aftermarket flex duct, mastic, and blower wheels without pretending they’re something they’re not. Every technician is background-checked and photo-badged under the Threshold Standard, and their name and photo arrive before the visit. You’ll know exactly who’s walking into your home. Every job gets a written price before any work begins, and every repair is covered in writing with a free second visit if it doesn’t hold. We’ve been doing this since 2004 as part of the Threshold Group family, and for Los Angeles homeowners, that track record matters.
Common Lennox Air Duct Cleaning Problems We Solve in Los Angeles
- Flex-duct inner liner collapse on Signature systems in the Valley. Lennox SL280V and SLP98V systems installed in San Fernando Valley attics sit in unconditioned spaces that regularly exceed 140°F in summer. That heat bakes the inner liner of flex duct until it separates and collapses inward, restricting airflow and tripping the SLP98V’s high-limit switch. We see this constantly in Van Nuys, Reseda, and Northridge tract homes from the ’60s and ’70s.
- Ash-caked evaporator coils on Merit ML180 units. The ML180’s evaporator coil cabinet pulls return air through gaps and leaks in the return chase. During Santa Ana wind events and wildfire season, fine ash gets drawn through those leaks and coats the coil face. Static pressure climbs, the compressor runs hot, and cooling drops off. A coil cleaning alone often restores most of the lost performance.
- Brittle, ash-clogged return chases on Lennox Complete Heat HM30 systems. Those 1980s and ’90s high-velocity systems are common in LA tract housing. Their return chases were never sealed well, and after decades of Santa Ana dust and fire events, the chases get brittle and packed with debris. The burner starves for air, lockouts happen, and the homeowner thinks the furnace is dying when the real problem is a clogged return path.
- Short-cycling XC21 condensers on undersized duct runs. Post-WWII homes in Torrance, Hawthorne, and Lakewood often had air conditioning added decades after the house was built. The ductwork wasn’t sized for it. An oversized Lennox XC21 condenser paired with undersized ducts short-cycles constantly, and supply registers end up coated in gray film that re-entrains every time the blower starts.
- Blower wheels packed with sub-2.5-micron ash after fire events. After the Woolsey, Station, Bobcat, and Eaton fires, homeowners in foothill-adjacent neighborhoods called us because the smell wouldn’t go away. The blower wheel, not just the ducts, ends up caked in fine ash that standard filters can’t catch. Full system cleaning including blower wheel removal is the only way to get rid of it.
Lennox Service in Los Angeles: What Local Conditions Mean for Your Equipment
Here’s something most Lennox owners in Los Angeles never hear until it’s too late: the city sits in a geographic basin ringed by mountains that trap particulate pollution through temperature inversions. Add the fire-prone wildlands, the Angeles National Forest, the Santa Monica Mountains, the Malibu hills, and you get a uniquely hazardous mix of smog particulate, wildfire ash, and desert dust that settles into residential HVAC systems at a rate you won’t find in a coastal city like San Diego or an inland valley like Riverside. Foothill neighborhoods like Altadena, Sylmar, Chatsworth, and Tujunga have a well-documented pattern among local techs: homeowners call for duct cleaning within weeks of a nearby fire, and inspection cameras routinely find visible gray ash on supply registers and blower wheels even in homes that appear undamaged. The negative pressure from a running Lennox air handler actively pulls smoke infiltration through envelope gaps during evacuations. That ash is fine enough to bypass standard filters and re-entrain every single time the blower spins up. In Altadena, a homeowner with a Lennox SLP98V called us weeks after the Eaton Fire because the heat smelled like a campfire every time it ran. Our tech pulled the blower and found the wheel caked in gray ash and the evaporator coil face masked with soot. A full system clean, sealed return plenum, and a new filter rack gasket later, the smell was gone and static pressure dropped from 0.9 to 0.55 inches of water column. That’s the kind of thing you only learn by working here.

Lennox Models & Products We Service in Los Angeles
We work on the full Lennox range that Southern California homes actually have. That includes the Dave Lennox Signature Collection (SL280V, SLP98V, XC21), the Merit Series (ML180, ML193, EL180), the Elite Series (EL296V, XC13, XP14), and the legacy Complete Heat HM30 high-velocity system you still find in 1980s and ’90s LA tract homes. When your system needs parts, we use OEM Lennox gaskets, filter racks, and coil cabinet seals when they’re available. When OEM inventory is backordered, which happens, we use high-quality aftermarket flex duct, mastic, and blower wheels and tell you exactly what we’re installing. If your Lennox air handler or coil is more than 15 years old and ash-fouled beyond cleanable condition, we’ll say so plainly. Sealing and cleaning sometimes restores performance. Other times, replacement is the smarter spend, and we’ll tell you that before you put money down. Our core work on this page: full system cleaning, evaporator coil cleaning, and blower cleaning.
Lennox Service Pricing in Los Angeles
For a Lennox air duct cleaning in Los Angeles, expect roughly $450 to $950 for a full system. Smaller homes with a single return and straight duct runs fall toward the bottom of that range. Larger homes, multi-zone systems, homes with multiple returns, or systems that haven’t been cleaned in a decade and carry significant ash or construction debris fall toward the top. What drives the cost: the number of returns, the linear footage of ductwork, accessibility of the air handler and coil, and how much of the job is cleaning versus sealing and repair. Evaporator coil cleaning and blower wheel cleaning are quoted separately when needed, and you’ll know before we start. We put the price in writing before any work begins, every time, no exceptions. No per-vent pricing games, no bait-and-switch, no surprise invoice at the end. Call (980) 447-2498 and we’ll give you a straight estimate based on your Lennox system and your home’s layout.

FAQs – Lennox Air Duct Cleaning in Los Angeles
Duct cleaning alone usually isn’t enough when smoke odor persists. The smell typically comes from ash and soot baked onto the blower wheel and evaporator coil face, which duct-only cleaning never touches. We pull the blower, clean the wheel, clean the coil, seal the return plenum, and replace the filter rack gasket. That’s what resolves the odor. If you’re in a foothill neighborhood or downwind of the fire corridor, call (980) 447-2498 and we’ll inspect it properly.
Santa Ana winds drive fine dust and ash into your return-air intakes, and on an ML180 in a Torrance tract home, that debris cakes the evaporator coil and raises static pressure. The system overheats, the safety limit trips, and the unit short-cycles to protect itself. A coil cleaning and return-side sealing usually fixes it. If a repair is needed, you get a written guarantee and a free second visit if it doesn’t hold. Call (980) 447-2498 to set up an inspection.
We use OEM Lennox gaskets, filter racks, and coil cabinet seals when available. If OEM stock is backordered, we use high-quality aftermarket flex duct, mastic, and blower wheels and tell you exactly what we’re installing and why. You’ll never be surprised by what goes into your system.
The inner liner of flex duct bakes in that heat and eventually separates, collapsing inward and choking airflow. This is a very common problem in San Fernando Valley attics, and it’s why an SLP98V or SL280V starts tripping its high-limit switch for no apparent reason. We replace damaged flex duct runs with proper sizing and mastic-sealed connections.
If the duct liner is intact and the contamination is ash and debris, cleaning plus sealing restores the system. If the liner is brittle, collapsed, or ash has worked its way into the insulation, replacement is the smarter spend. We camera-inspect the ductwork and show you what we find before recommending anything. Call (980) 447-2498 for an honest assessment.
