Lennox Air Duct Cleaning in San Ramon, CA
We clean and repair the ductwork connected to Lennox systems throughout San Ramon, and we do it as an independent shop, not a Lennox franchise or authorized dealer. What makes our work different here is that we understand how San Ramon’s wildfire seasons affect Lennox ducted systems specifically, from the flex joints in attic runs to the coil and blower.

Why San Ramon Residents Choose Us for Lennox Service
We’ve worked on Lennox systems across the San Ramon Valley long enough to know how they behave in this climate. The builder-grade Lennox Merit Series units in Gale Ranch, the Elite and Signature equipment in Windemere, the older single-story ranches near downtown, we’ve seen the full range. Darren Radcliffe, our owner, grew up near the South Hayward BART corridor and studied HVAC through the mechanical technology program at Chabot College, so he understands the dust and particulate that older East Bay homes collect over decades. He started Duct Cleaning Hayward in 2011, and the company has spent the 15 years since focused entirely on duct and vent services. That narrow focus is why San Ramon homeowners call us when a Lennox system isn’t moving air the way it should.

Common Lennox Air Duct Cleaning Problems We Solve in San Ramon
- Flex duct joint separation in unconditioned attics. San Ramon’s hot, dry summers bake the tape and mastic on attic flex runs until they crack and let go. When that happens on a Lennox system, the conditioned air leaks into the attic and the return side starts pulling in whatever is up there, including ash after wildfire season.
- Return duct leakage at plenum connections. Negative pressure is a real problem on Spare the Air days. If the return plenum connection on a Lennox system isn’t sealed tight, fine smoke and ash get pulled straight into the airstream, especially in older San Ramon homes with original ductwork.
- Evaporator coil fouling from smoke residue. Lennox coils in this valley collect sticky ash particles that don’t just rinse off. Reduced airflow and efficiency follow, and in some cases the coil freezes or head pressure climbs. Cleaning the ducts without addressing the coil leaves the problem half-finished.
- Blower wheel imbalance from ash buildup. Fine particulates from Diablo Range wildfires settle on blower fins and throw the wheel out of balance. The vibration is subtle at first, then noticeable, and it reduces airflow through the whole Lennox system, particularly on units that run continuously during smoke events.
- Dry dust and pollen settling in mild winters. San Ramon’s mild winters mean less condensation in ducts, but dry-weather dust and pollen still find their way in. A Lennox system pulling from leaky returns can distribute that dust through every room in the house.
Lennox Service in San Ramon: What Local Conditions Mean for Your Equipment
After every red-flag fire season, our technicians check attic duct runs in San Ramon because the same prevailing winds that push smoke from the Diablo Range into the valley also push fine ash through attic vents and into flex duct joints. A post-fire-season cleaning here is often more about smoke residue than dust. Most San Ramon housing is 1980s to 2000s suburban construction, two-story tract homes in planned communities like Gale Ranch and Windemere, plus older single-story ranches near downtown. Those homes typically have flexible ductwork in unconditioned attics, which makes them prone to settling, rodent intrusion, and smoke infiltration. For a Lennox owner, that means the duct system needs as much attention as the equipment itself. We video-inspect what we find and we show you before we do anything. If I can’t show you what I found, I won’t charge you for fixing it.

FAQs – Lennox Air Duct Cleaning in San Ramon
Why does my Lennox system smell like smoke after wildfire season in San Ramon? The smell comes from ash and smoke residue that entered your duct system through separated flex joints or leaking return plenums. Your Lennox system can’t filter out what’s already inside the ducts, so every time the blower runs it pushes that odor through your home. A full system cleaning with duct sealing addresses the source. Call (833) 589-9902 for an exact quote.
How often should I clean my Lennox air ducts in San Ramon? For most Lennox systems in San Ramon, every 3 to 5 years is a reasonable interval, but after a red-flag fire season it’s worth having the ducts inspected and cleaned sooner. The ash and smoke residue that settles in attic flex runs during those events isn’t just dust, and it doesn’t clear itself out. Our video inspection can tell you whether cleaning is warranted right now.
Can duct cleaning improve my Lennox system’s efficiency? Yes, when the ducts are restricted or leaking, the blower works harder to move the same amount of air. Removing built-up ash and dust from the coil, blower wheel, and duct runs lets your Lennox system operate the way it was designed to. The airflow improvement is often noticeable in the first week.
What should I do if my Lennox system’s airflow seems weak after a fire season? Start with a video inspection of the ductwork connected to your Lennox system. Weak airflow after a fire season in San Ramon usually points to ash buildup on the blower wheel or separated flex joints in the attic. We inspect, we show you what we found, and we fix what needs fixing. Call (833) 589-9902 to schedule.
