Lennox Air Duct Cleaning in Pleasanton, CA
We provide independent Lennox air duct cleaning across Pleasanton, and the thing that shapes our work here more than anything is the ZIP-and-decade split: a 1910 downtown bungalow and a 2005 Muirwood two-story are entirely different duct systems, even when both have a Lennox furnace in the closet. We quote each one on its own terms, not by square footage. Call (833) 589-9902 for a free estimate. We answer 24/7. Fast dispatch from 7am to 7pm, Sunday through Friday.
Why Pleasanton Residents Choose Us for Lennox Service
Duct cleaning is all we do. We’re not an HVAC generalist squeezing your ducts between furnace installs. We run Rotobrush and Nikro negative-pressure equipment, the same professional-grade systems commercial contractors use, because a residential home with a Lennox variable-speed blower deserves that standard. Darren Radcliffe, our owner, studied HVAC systems through the mechanical technology program at Chabot College before starting this company in 2011, and he’s spent 15 years learning exactly how Lennox cabinet geometry interacts with the duct layouts Pleasanton homes actually have. That matters when a filter rack seam opens up in an attic off Stoneridge Drive and smoke-season dust starts bypassing the filter entirely. We find that because we look for it.

Common Lennox Air Duct Cleaning Problems We Solve in Pleasanton
- Coil face caked with Diablo-wind dust. On Lennox upflow and horizontal furnaces, the evaporator coil sits downstream of the filter rack. If that rack isn’t sealed properly, warm-weather dust blowing off the dry hills rides straight past the filter and cakes the coil face. We treat the coil after cleaning the return path, not instead of it.
- Gasket-shrunk access panels on Elite and Signature units. Triple-digit summer afternoons in Pleasanton bake attic equipment for hours. Factory gaskets on Lennox coil doors and access panels harden and shrink, opening leakage paths into the return air. We re-seal those seams with mastic after cleaning.
- Collapsed flex duct choking variable-speed blowers. Newer 94588 homes typically run flexible insulated duct through attic and second-floor chases. Sagging or collapsed runs drive up static pressure, and a Lennox variable-speed blower responds by ramping and short-cycling. We inspect and repair those runs, not just clean them.
- Stud-bay returns that hold dust no brush can reach from the supply side. Older downtown blocks off Main Street often use the stud cavity itself as the return path. A cleaning that only brushes supply trunks misses the actual reservoir. We confirm the return design first, run a video inspection, and clean the return chase properly.
- Blower wheels that keep reloading with dust. When a Lennox blower loads up again weeks after a cleaning, the problem is usually upstream: a leaking return, a filter rack gap, or a disconnected flex run. We diagnose that instead of just re-cleaning the wheel.
Lennox Service in Pleasanton: What Local Conditions Mean for Your Equipment
The 94566 and 94588 halves of Pleasanton house entirely different Lennox installations. Near-downtown 94566 is heavy with pre-war and mid-century homes where sheet-metal trunk-and-branch systems run through shallow crawlspaces, and the return path is often a single floor grille or a stud bay itself. The 94588 side, out toward the eastern hills and Ruby Hill, is newer construction with flexible insulated ducts in attics and second-floor chases. We bid a Lennox duct job by ZIP and by decade because a flat per-system quote is wrong on both ends. A 1910 Division Street bungalow with a Lennox Merit furnace and a stud-bay return needs a different cleaning approach than a 2005 Muirwood two-story with a Dave Lennox Signature Collection variable-speed air handler in a hot attic. We run a video inspection before quoting so the estimate reflects the duct system you actually have, not the one a square-footage formula assumes.
Lennox Models & Products We Service in Pleasanton
We service the full range of Lennox residential equipment across Pleasanton: Merit Series gas furnaces and air conditioners, Elite Series furnaces and AC units, and Dave Lennox Signature Collection variable-capacity equipment. That includes Lennox Healthy Climate filtration systems and filtration-equipped air handlers, where filter condition and cabinet sealing directly affect how much dust reaches the coil. We use Lennox OEM parts where the part is fit- or control-critical, such as igniters, inducers, control boards, and door gaskets. For commodity items like flex duct, mastic, and filter racks, we use quality aftermarket parts and tell you which is which before we install anything.

AfterLennox Service Pricing in Pleasanton
Air duct cleaning on a Lennox system in Pleasanton typically runs between $450 and $900 for a whole-home job, depending on system size, number of returns, and how much of the ductwork is accessible from a crawlspace versus an attic.

FAQs – Lennox Air Duct Cleaning in Pleasanton
Yes, and more than most people expect. On Lennox furnaces the coil sits downstream of the filter rack, so any gap or poor seal at that rack sends unfiltered air directly across the evaporator face. In Pleasanton’s dry, dusty summers and smoke season, that adds up fast. We check the filter rack seal on every Lennox cleaning and re-seal it if needed.
Yes, and that’s exactly the kind of system we spend extra time on. When the return path is a stud bay or a single floor grille, the dust reservoir sits where a supply-side-only cleaning never reaches. We confirm the return design, run a video inspection, and clean the return chase itself. If we can’t show you what we found, we won’t charge you for fixing it.
Because the dust isn’t coming from the ducts you cleaned. It’s entering through a leak downstream of the filter: a separated flex run, an open cabinet seam, or a filter rack that doesn’t seal. On a Muirwood-corridor two-story, we found a Lennox variable-speed air handler pulling through a cabinet seam that had opened after repeated attic heat cycling. Smoke-season dust was bypassing the filter and loading the coil. We re-sealed the seam with mastic, and the blower static dropped immediately. That’s the difference between cleaning and correcting. Call (833) 589-9902 for an exact quote.
It can be. Warm, dry Diablo-wind episodes push fine particulate through return air paths all over the Tri-Valley, and Pleasanton sits right in it. Homes near open hillsides and ridgelines tend to load ductwork faster. If you notice a fine, tan dust settling on registers shortly after cleaning, the duct system itself may be pulling air from somewhere it shouldn’t. We can pinpoint that with a video inspection rather than just scheduling another cleaning.
We use Lennox OEM parts where fit and control matter: igniters, inducers, control boards, door gaskets. For commodity items like flex duct, mastic, and filter racks, we use quality aftermarket parts and say which is which on the estimate. On older Lennox equipment, we give a straight repair-or-replace read rather than pushing a new system when a sealed, cleaned duct system and coil cleaning restores performance.
