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 Jose, CA | Morton’s Air Duct Cleaning
We clean and repair Lennox air duct systems throughout San Jose, and we do it as an independent provider. That means no corporate script, no manufacturer markup, just a straight answer about what’s happening inside your ducts and what it costs to fix. The one thing that makes our Lennox work different here: we know exactly what San Jose’s smoke-trapping valley geography and those 1960s-era tract home attics do to Lennox air handlers, because we’re inside them every week. Call (323) 918-4345 for a free estimate.
Why San Jose Residents Choose Us for Lennox Service
Our technicians work on Lennox systems in San Jose daily, from the builder-grade Merit Series equipment in 1960s through 1980s tract homes to newer Elite and Dave Lennox Signature Collection high-efficiency units. We know how Lennox air handlers, coils, and return systems actually behave in this valley’s heat and smoke cycles, because we see the same failure patterns repeat across Cambrian Park, Berryessa, Alum Rock, and East San Jose. Paul Adeyemi, our owner, learned ventilation mechanics at Los Angeles Trade-Technical College and has spent nearly two decades inside the walls of homes across California. He’s the kind of technician who lays down drop cloths without being asked and explains every step before touching anything. When you book with us, that’s the standard. We’re a full Lennox sales & service resource for duct-level work, and we show up on time, background-checked, and in uniform.
Common Lennox Air Duct Cleaning Problems We Solve in San Jose
- Smoke and pollen mats on blower wheels and evaporator coils. Lennox Merit Series air handlers with PSC blowers in 1960s-80s San Jose attics collect a thick mat of smoke and pollen dust. It cakes the blower wheel and coil, raising static pressure and reducing airflow. We remove it with Rotobrush and Nikro equipment, then verify airflow at the registers.
- Fiberglass shedding from original flex duct. In Cambrian Park and Berryessa attics that routinely hit 140°F or higher in summer, original fiberglass-lined flex trunk runs connected to Lennox plenums degrade and shed fibers into the supply airstream. We inspect with video, then clean or replace the affected sections.
- Return-air leaks pulling attic smoke into the system. Return-air leaks at floor registers in original galvanized trunk lines pull attic air, and wildfire smoke, directly into Lennox air handlers during July-November fire season. We locate the leaks and seal them with mastic before cleaning, so the clean actually holds.
- Dried-out cabinet seams and coil access panels. Lennox cabinet seams and coil access panels that were mastic-sealed decades ago dry out and open up. Unfiltered attic dust bypasses the Healthy Climate filter and coats the coil. We reseal and re-clean as part of the job.
- Burnt, dusty smell from aging flex liner. A 1968 ranch in Cambrian Park had exactly this. The Lennox Merit Series air handler pushed a burnt, dusty smell on startup. Video inspection showed the original fiberglass flex had broken down in the 140°F attic, shedding liner fibers into the supply run, while the return side pulled attic smoke through a dried-out plenum seam. We cleaned both sides, sealed the plenum, and replaced the degraded flex section. Smell cleared, airflow returned.
Lennox Service in San Jose: What Local Conditions Mean for Your Equipment
San Jose sits at the southern tip of a bowl-shaped valley, ringed by the Diablo Range to the east and the Santa Cruz Mountains to the west. That geography traps wildfire smoke at ground level. The SCU Lightning Complex burned directly east of the city in 2020, and Central Valley smoke gets funneled onto the valley floor every fire season. What this means for Lennox owners: the return ducts here load with fine particulates far faster than in open-coast cities like San Francisco. And in Cambrian Park and Berryessa specifically, where 1960s-70s tract homes commonly have original fiberglass-lined flex duct running through attics that top 140°F, the liner starts shedding before most owners ever think to book Air Duct Cleaning - San Jose. That combination, smoke-heavy return air and heat-degraded supply liners, is one we encounter almost exclusively in this generation of South Bay construction. It’s why we recommend duct inspection, not just cleaning, for Lennox systems in those neighborhoods.
Lennox Models & Products We Service in San Jose
We cover the Lennox Merit Series, the builder-grade furnaces and air handlers common in San Jose tract homes. We also service the Elite Series, including higher-efficiency furnaces, air handlers, and outdoor units, plus the Dave Lennox Signature Collection with variable-speed and communicating systems. On the indoor air side, we work with Lennox Healthy Climate whole-home media filters and duct accessories. For parts, we use genuine Lennox OEM filters, belts, and gaskets where the cabinet or filter rack demands a specific fit, and quality aftermarket components elsewhere. On 40-60 year old duct systems we’re honest: if flex liner is shedding or galvanized trunk is crushed, sealing, rerouting, or partial replacement serves Lennox owners better than repeated cleaning. We also offer San Jose Dryer Vent Cleaning. We stock common components locally so San Jose turnaround stays tight.
Lennox Service Pricing in San Jose
Air duct cleaning for a Lennox system in San Jose typically runs $350-$650 for a whole home, depending on square footage, number of returns, and how much the valley has packed into the ducts. A return duct cleaning focused on smoke and pollen loads usually falls in the $150-$300 range. Flex duct repair or replacement runs $200-$800, depending on the length and access. A video inspection, which we recommend before any cleaning in 40-60 year old homes, is included with your written estimate. That estimate is given before any work starts, every time, no exceptions. No per-vent pricing, no surprise invoice. Call (323) 918-4345 and we’ll work up a number you can plan around.

FAQs - Lennox Air Duct Cleaning in San Jose
That smell usually means the return side is pulling attic smoke through a leak in the original galvanized trunk line, or the supply flex liner has degraded and is shedding into the airstream. We trace it with video inspection, then seal or replace the problem section before cleaning. Call (323) 918-4345 for an inspection quote.
It depends on the liner. If the fiberglass liner is intact, we clean it with Rotobrush equipment and reseal any leaks. If video shows it shedding or crushed in the attic heat, replacement is the honest fix. We’ll show you the footage and a written price for either path before any work starts.
Because San Jose’s bowl-shaped valley traps wildfire smoke at ground level, return ducts here load with fine particulates far faster than in open-coast cities like San Francisco. If you’re in Cambrian Park, Berryessa, or Alum Rock with original 1960s-80s ductwork, every 2-3 years is common. If you can’t remember the last cleaning, it’s time. Call (323) 918-4345 and we’ll check it for you.
Cleaning the coil removes the organic buildup that feeds the smell, but if the coil access panel has a dried-out seal, attic air re-contaminates it within months. We clean the coil and reseal the cabinet as part of the job, so the fix holds through the next fire season.
We use genuine Lennox OEM filters, belts, and gaskets where the cabinet or filter rack requires that specific fit. Elsewhere, quality aftermarket components. We’ll tell you which is which, and your written estimate says so before we start.
