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 San Diego, CA | Morton’s Air Duct Cleaning
We provide independent Lennox Air Duct Cleaning - San Diego across San Diego County. The one thing that makes our Lennox work different here: we clean for fire ash and marine-layer mold, not just household dust. Paul Adeyemi and our team at Morton’s Air Duct Cleaning know exactly how a Lennox system in Scripps Ranch differs from one in Pacific Beach, and we price the job in writing before any equipment rolls out. Call (323) 918-4345 for a free estimate.
Why San Diego Residents Choose Us for Lennox Service
We’ve spent years inside Lennox cabinets across San Diego, from G-series furnaces in La Mesa to variable-speed SL25XPV air handlers in Chula Vista. We know the factory seal points on Lennox coil cabinets, the way a Healthy Climate media cabinet seats against the return plenum, and how much debris an original 1970s flex duct run can hold. That familiarity means we clean without disturbing the airflow calibration your system depends on.
Paul Adeyemi learned ventilation mechanics at Los Angeles Trade-Technical College and has spent nearly two decades working inside walls across Southern California. He got into duct cleaning after chasing down air quality issues in his own home when his youngest daughter showed signs of seasonal allergies. That personal stake shows up in how we work: drop cloths before tools, a written price before any work starts, and a photo of the clean-up before the crew leaves. Call (323) 918-4345.
Common Lennox Air Duct Cleaning Problems We Solve in San Diego
- Flex duct liner failure in attic runs. Lennox systems installed in 1960s-1980s tract homes across Lemon Grove, El Cajon, and Santee often use original flex duct that sits in attics hitting 140-150°F all summer. The liner tears, fiberglass releases into supply air, and the evaporator coil starts clogging. We replace the bad runs with OEM-equivalent flex duct and seal everything with mastic.
- Return plenum ash compaction. After the 2003 Cedar Fire and 2007 Witch Creek Fire, Lennox return plenums in Scripps Ranch and Rancho Bernardo collected submicron ash that slipped past 1-inch fiberglass filters and embedded in duct lining. That ash reduces airflow and coats the coil. Only camera inspection reveals it, and only mechanical agitation plus HEPA vacuuming removes it.
- Coastal humidity mold in duct liner. Lennox systems in Ocean Beach, Pacific Beach, and Encinitas deal with persistent marine-layer dampness from spring through early summer. Moisture condenses inside cooler duct runs, mold takes hold in fibrous liner, and musty smells start coming through the registers. We clean and apply antimicrobial treatment where the climate calls for it, which is a coast-specific decision, not a one-size-fits-all spray.
- Variable-speed blower motor contamination. A Lennox SL25XPV or SLP98V air handler is sensitive. When return ducts pull in attic insulation or ash, the blower wheel goes out of balance. You’ll hear it first: erratic airflow, more noise, a motor working harder than it should. We clean the wheel and housing carefully so the variable-speed calibration stays intact.
- Filter rack gaps pulling attic air. On older Lennox installs, the filter rack itself can have gaps that let unfiltered attic air bypass the filter entirely. We seal those gaps during duct cleaning, because a clean duct system means nothing if unfiltered air still gets in around the rack.
Lennox Service in San Diego: What Local Conditions Mean for Your Equipment
San Diego County has a climate gradient that changes how we clean your Lennox system depending on where you live. A Lennox duct system in Pacific Beach sits under the marine layer for months each year. That persistent low-level humidity condenses inside the duct runs and feeds mold in the liner. Drive 15 miles east to El Cajon, and the same Lennox system bakes dry in desert-adjacent heat, loading up with dust instead of mold. So when we quote a job, the neighborhood you call from tells us what we’re likely to find before we even open the first return grille. It also changes what we do: coastal homes get antimicrobial treatment and a closer look at liner integrity for moisture damage. Inland homes get aggressive particulate removal and coil cleaning for dust load. And in fire-corridor communities like Scripps Ranch and Rancho Bernardo, we check for compacted ash from the 2003 and 2007 fires, which settles deep in return plenums and never really leaves on its own. No generic duct cleaning company working across San Diego treats a Point Loma Lennox system the same as a Santee Lennox system. We do, because the air these systems pull in is genuinely different.
One recent job sticks with us. A 1970s ranch home in Scripps Ranch had smoky odors and low airflow that wouldn’t quit. We ran our camera into the return plenum and found compacted ash from the 2003 Cedar Fire, still sitting in the duct lining over two decades later. We cleaned the full return and supply runs, removed the contaminated flex duct liner, sealed the gaps with mastic, and installed a Lennox Healthy Climate media cabinet. The homeowner told us the air smelled different within a day. That’s the kind of San Diego-specific problem you won’t find on a generic HVAC page.
Lennox Models & Products We Service in San Diego
Our crews work on the full range of Lennox residential equipment: Merit Series ML14XC1 and ML17XC1 air conditioners matched with SL280 and EL280 furnaces; Elite Series EL16XC1 and EL18XCV units; Dave Lennox Signature Collection variable-speed systems like the SL25XPV heat pump and SLP98V furnace; and 4SCU and 4HPX packaged units common on San Diego’s ranch-style homes. We also service Lennox Healthy Climate media cabinets and PureAir filtration systems, and we’re happy to install a media cabinet during a duct cleaning if your current filtration is letting too much through.
For parts, we use OEM-equivalent aftermarket components for common items like flex duct, mastic sealants, and filter racks. For proprietary electronics or blower motors, we source genuine Lennox parts when they’re available. Morton’s Air Duct Cleaning is an independent Lennox service provider. We are not manufacturer-affiliated or authorized, which means we give you repair-vs-replace guidance based on what we see, not what a corporate program tells us to sell.
Lennox Service Pricing in San Diego
Air duct cleaning for a typical San Diego Lennox system runs between $450 and $900, depending on the number of duct runs, the contamination level, and whether we’re cleaning a return plenum packed with wildfire ash or a coastal system that needs antimicrobial treatment. Smaller condos and single-level ranchers on the lower end. Larger two-story homes with multiple return drops and flex duct replacement on the higher end. Video inspection adds $75 to $150 and is worth it if you suspect mold, ash, or liner failure.
We give you a written price before any work starts. That price is the price. If we find something unexpected mid-job, we stop and show you before doing anything else. Paul’s standing phrase on site: “Before we start, let me show you exactly what we found and exactly what it will cost to fix it.” Call (323) 918-4345 for a free estimate and we’ll walk you through what your Lennox system actually needs.

FAQs - Lennox Air Duct Cleaning in San Diego
Most San Diego Lennox systems need cleaning every 3 to 5 years, but the real answer depends on where you live, which is why our Dryer Vent Cleaning in San Diego follows the same neighborhood-specific approach. Coastal homes in Pacific Beach or Encinitas deal with marine-layer dampness that can lead to mold in duct liner, so checking every 2 to 3 years makes sense. Inland homes in El Cajon or Santee that run the AC hard all summer pull in dust and insulation fibers, so every 3 to 4 years usually works. Homes in fire-corridor neighborhoods like Scripps Ranch should be inspected after any significant wildfire smoke event. Call (323) 918-4345 and we’ll give you an honest timeline for your specific Lennox system, not a generic calendar.
Yes. Lennox variable-speed air handlers like the SL25XPV and SLP98V are sensitive to dust and debris. If return ducts pull in attic insulation or ash, the blower wheel becomes imbalanced and you’ll notice erratic airflow, more noise, and a motor working harder than it should. We clean the blower wheel and housing carefully without disturbing the factory calibration or seals, and we seal any gaps in the return path so future contamination doesn’t reach the motor. The cleaning method is the same, but the care level is higher for variable-speed systems.
In most cases, yes. Wildfire smoke leaves behind submicron ash that embeds in duct lining and return plenums, and that ash holds odor for years. The 2003 Cedar Fire and 2007 Witch Creek Fire left exactly this signature in Scripps Ranch and Rancho Bernardo Lennox systems. We remove the contaminated liner, clean the full duct run with HEPA filtration, and seal gaps with mastic. For persistent smoke odor, we may also recommend replacing the filter media and installing a Lennox Healthy Climate cabinet. Call (323) 918-4345 for an inspection if your San Diego home smells smoky long after the skies clear.
The marine layer that sits over neighborhoods like Ocean Beach and Pacific Beach for much of spring and early summer pushes persistent humidity into homes. That moisture condenses inside cooler duct runs and feeds mold growth in fibrous duct liner. Fifteen miles inland in El Cajon or Santee, the same Lennox ductwork dries out aggressively in desert-adjacent heat, so mold is rare and dust is the main problem. We assess mold versus dust contamination based on your home’s distance from the coast, and coastal systems get antimicrobial treatment as part of the cleaning when needed.
The right repair starts with finding every leak, which is why video inspection matters. Flex duct on older San Diego Lennox systems, especially in 1960s-1980s tract homes with attic temperatures routinely over 140°F, develops tears and gaps that pull attic air into the supply stream. We replace badly degraded liner, seal connections and seams with mastic, and re-insulate where needed. Duct tape is not a repair, and we see far too much of it in San Diego attics. Call (323) 918-4345 for an honest assessment of your Lennox ductwork.
