Lennox Air Duct Cleaning in San Martin, CA
We provide independent Lennox air duct cleaning across San Martin, focusing on the return ducts, evaporator coils, and flex runs that suffer most from our local orchard dust and pollen. The one thing that makes our Lennox work different here is that we clean with equipment built for containment-level work, not a portable shop-vac rig. Todd Schaefer has spent 15 years working on San Martin’s rural housing stock, and we know how a retrofitted ranch home’s ductwork behaves differently from a tract house in San Jose. Call (833) 589-9833 for a free estimate. We answer 24/7.
Why San Martin Residents Choose Us for Lennox Service
We’re not a generalist HVAC company that treats duct cleaning as a checkbox. We use Rotobrush and Nikro professional duct-cleaning systems, the same equipment commercial restoration contractors run. The brush physically scrubs the duct wall; debris does not just get blown toward the next register. Our Nikro HEPA vacuum runs the entire time, so what we loosen does not re-enter your living space. Todd Schaefer learned HVAC fundamentals at Gavilan College in Gilroy and spent years doing hands-on duct and ventilation work before starting this company in 2011. These days he is known for running a Rotobrush aiR+ system the right way: negative pressure established before the brush ever touches the duct wall. If the negative pressure is not right before you start, you are just moving the problem around. We inspect before we clean and repair what needs repairing, including disconnected flex joints and torn duct runs. Not every company does both.

Common Lennox Air Duct Cleaning Problems We Solve in San Martin
- Secondary heat exchanger corrosion on high-efficiency Lennox furnaces. Models like the EL296V and SL280V pull combustion air through the intake. When fine orchard dust and pollen clog that intake, airflow drops and moisture gets trapped inside the secondary heat exchanger. That is how corrosion starts. In San Martin, where spring and fall bring seasonal blasts of agricultural dust, this happens faster than it would in a coastal suburb.
- Dust-loaded evaporator coils on Merit Series systems. The 14ACX and ML14XC1 air conditioners use a slab coil that sits right in the airstream. Fine field dust coats the fins, restricts heat transfer, and eventually the coil freezes. Homeowners notice higher bills first, then weak cooling. We wash and clean the coil as part of the job.
- Disconnected flex duct joints in older ranch homes. Many San Martin homes were built with systems sized for a smaller footprint, then retrofitted with added zones and long flex runs through the attic. Temperature swings and rodent activity work those joints loose. Air leaks out, attic dust gets pulled in. We find these during cleaning and seal them on the spot.
- Unbalanced variable-speed blowers on Signature Collection units. The XC25 and SL280V blowers run at low speeds for efficiency. Accumulated dust on the blower wheel throws off balance, causing vibration and reduced airflow. Homes with unpaved driveways and wood-burning stoves see this more often because more fine particulate gets into the return stream.
- Return grilles clogged with farm dust. The return side of a Lennox system in San Martin takes in whatever the wind carries from surrounding orchards and fields. When returns clog, the whole system starves for air. We clean return ducts thoroughly, not just the supply side.
Lennox Service in San Martin: What Local Conditions Mean for Your Equipment
San Martin sits at the warmer southern end of Santa Clara Valley, surrounded by working orchards and horse properties. That is not background scenery; it is what your Lennox system breathes every day. In spring and fall, fine agricultural dust and pollen coat return grilles and attic ducts. The loading we see in a San Martin ranch home looks more like a farmhouse than a suburban tract house. This means your Lennox equipment needs return-side cleaning and coil attention far more frequently than it would in Morgan Hill or Gilroy. Homes in 95046 are largely single-story ranch-style and rural custom builds on multi-acre parcels, many with retrofitted ductwork, multiple zones, and long runs accessible in attics or crawlspaces. Those long runs collect more debris and leak more air. When we clean a Lennox system in San Martin, we are not just knocking dust loose. We are checking every joint, every return, and every coil for the specific buildup pattern this valley creates.
Lennox Models & Products We Service in San Martin
We service the full range of Lennox equipment found in San Martin homes: Merit Series air conditioners and furnaces, Elite Series units like the XC21 and EL296V, and Signature Collection variable-speed systems like the XC25 and SL280V. We repair, install, and service Lennox equipment with quality parts that fit it. For critical components like control boards and blower motors, we use OEM Lennox parts to ensure compatibility and reliability. For common wear items like filters and seals, we use high-quality aftermarket equivalents that meet or exceed OEM specifications. We are independent, not manufacturer-affiliated, and that independence means we recommend what the system actually needs, not what a dealer program tells us to sell. When repairs exceed half the replacement cost on a system older than twelve years, we say so honestly. We never push an upgrade that is not warranted.

AfterLennox Service Pricing in San Martin
Air duct cleaning for a typical Lennox system in San Martin runs between $400 and $900 depending on the size of the home, the number of zones, and how much agricultural buildup has accumulated.

Duct sealing runs $300 to $800 depending on how many joints need attention.

FAQs – Lennox Air Duct Cleaning in San Martin
Because the intake air here carries far more fine agricultural dust and pollen than urban San Jose air does. That dust clogs the intake on high-efficiency Lennox furnaces like the EL296V, reducing airflow and trapping moisture inside the secondary heat exchanger. Moisture plus heat equals corrosion. Regular return duct and intake cleaning slows this down significantly. Call (833) 589-9833 and we can take a look at your intake.
Every two to three years is a realistic interval for most San Martin homes, and annually if you are surrounded by working orchards or have an unpaved driveway. The return side sees the worst of the seasonal dust loading. If your return grilles look coated in spring and fall, the ducts behind them look the same. A free estimate tells you what you are dealing with before you commit.
Yes. We find disconnected and torn flex joints constantly in San Martin’s older ranch homes and custom builds, where the ductwork was added onto over the years. We seal and reconnect what is loose during the cleaning visit. It is part of why we inspect before we clean, not just blast through and leave.
It is common anywhere fine dust accumulates on the blower wheel, and San Martin’s agricultural dust makes it more common here. A dust-caked wheel throws off balance, especially on variable-speed Signature Collection units that run at low RPM. We clean the blower assembly and confirm the vibration is gone before we pack up.
Duct sealing uses mastic and appropriate tapes, not Lennox-branded parts. For coil cleaning we use professional coil cleaners matched to the coil type. Where a critical Lennox component like a control board or blower motor needs replacement, we use OEM parts. For wearable items like filters, we use quality aftermarket equivalents. Call (833) 589-9833 and we will explain exactly what your system needs.
