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.
Lennox Air Duct Cleaning in Menlo Park, CA
We provide independent Lennox air duct cleaning service throughout Menlo Park, and the quick answer is this: if you own a Lennox system here, the ductwork attached to it almost certainly carries more than air. In the older Sharon Heights and West Menlo Park tracts, original galvanized Lennox trunk lines are frequently buried under blown-in insulation added decades ago, which means the taped joints fail out of sight and quietly pull attic debris, oak litter, and rodent nesting material into the return side. We clean those systems with negative-air containment and video verification. Call (833) 620-7085 for a free estimate.
Why Menlo Park Residents Choose Us for Lennox Service
Most homeowners in Menlo Park don’t need a crash course in Lennox engineering. They need someone who has actually opened these systems in homes like theirs: the 1950s rancher off Middlefield with a G61MPV furnace in a crawlspace, the Sharon Heights remodel with a CBX air handler in a vaulted attic. Neal Drummond, our owner, trained through Foothill College’s HVAC program and has spent his working life on Peninsula systems just like these. We understand Lennox cabinetry, plenum transitions, and coil boxes the way a mechanic understands a specific engine family: what fails, where it leaks, and what debris gets pulled when it does.
We’re an independent shop. We don’t claim Lennox authorization or factory warranty endorsement. What we do claim is field knowledge of this equipment that comes from pulling apart hundreds of residential Lennox installs across the Midpeninsula, from Stanford up through Menlo Park and Woodside. When we clean your system, we also seal what has opened up. That’s the difference between a duct cleaning and an actual fix.

Common Lennox Air Duct Cleaning Problems We Solve in Menlo Park
- Failed taped joints on original galvanized trunks. Lennox furnaces from the 1960s through the 1980s shipped with taped galvanized plenum and trunk connections. In Menlo Park’s 1950s ranch and Eichler-era homes, those tape joints have been failing for years, opening return-air leaks that pull crawlspace dust and rodent debris into the system. We find these on nearly every older Lennox install we open in 94025.
- Oak-leaf and rodent debris packed into return plenums. The mature oaks and redwoods that shade Menlo Park yards drop constant material through roof vents and soffits. When a Lennox air handler sits in an attic under those trees, the return plenum becomes a collection point. We routinely find returns in Sharon Heights and West Menlo Park that haven’t been opened since the Carter administration.
- Dirty evaporator coils from long stagnation periods. Menlo Park’s mild climate means Lennox systems run far less than inland units. That doesn’t keep them clean. It means attic dust settles onto warm coil fins during long idle periods and bakes on. The coil doesn’t get washed by condensation the way a heavily cycled inland coil does.
- Flex-duct additions spliced onto original Lennox trunks. Remodels are constant in Menlo Park, especially in the corridor between Willow Road and the Alameda de las Pulgas. A bonus room gets added, a flex run gets spliced into the original galvanized Lennox trunk, and the collar is often undersized or disconnected. Airflow to that new space starves, and the loose collar becomes another debris entry point.
- Insulation-covered duct runs with hidden damage. In Sharon Heights specifically, blown-in insulation buried original Lennox runs decades ago. When a joint fails under that blanket, you won’t see it, and you won’t smell it until enough rodent activity or decay accumulates. Video scoping finds it before cleaning starts.
Lennox Service in Menlo Park: What Local Conditions Mean for Your Equipment
Here’s the insight that matters for Menlo Park Lennox owners, and you won’t hear it from an Air Duct Cleaning in Menlo Park generic duct cleaning shop. In the Sharon Heights and West Menlo Park tracts, original galvanized Lennox duct runs are frequently buried under blown-in insulation added during remodels from the 1970s onward. That insulation blanket changes how duct failures behave. A taped Lennox trunk joint pops open underneath it, and the leak doesn’t whistle. It doesn’t show up as a hot or cold spot in a room. It becomes a hidden intake pulling whatever lives in the attic into your return stream. Before we clean a system like that, we scope it with video. Then we hand-dig access rather than disturbing the insulation blanket, so your attic doesn’t need a full re-insulation after we leave. That’s the kind of care Menlo Park clients expect, and it’s simply how the work needs to be done here.
Lennox Models & Products We Service in Menlo Park
We work on Lennox G61MPV and G71MPP variable-speed gas furnaces, XC and SL series condensing units paired with matching air handlers, and CBX and CBA series indoor coils. The Dave Lennox Signature Collection variable-capacity systems are common in newer Menlo Park remodels, and we see them paired with older trunk lines that were never resized for the new equipment. For parts, we use OEM-equivalent Lennox-compatible panels, collars, and mastic-grade sealants where exact fitment matters, and quality aftermarket flex and hard fittings where performance is identical. We’ll also tell you straight when an older Lennox system has reached the point where sealing and repair no longer make sense and replacement is the honest recommendation. The duct doesn’t lie – whatever has been moving through your air system for the past decade is still in there until someone actually removes it.

AfterLennox Service Pricing in Menlo Park
Lennox air duct cleaning in Menlo Park typically runs between $650 and $1,400 for a whole-home system, depending on the number of returns, the age of the ductwork, and how much debris has accumulated. A single-return system in a smaller ranch will land on the lower end. A remodeled home with multiple returns, flex additions, and buried galvanized trunk lines in Sharon Heights will run higher. Your free estimate includes a video inspection of the return plenum and supply trunk, so you see what we see before any work begins. We quote one flat price per system, agreed before the equipment comes off the truck. Call (833) 620-7085 for an exact quote.

FAQs – Lennox Air Duct Cleaning in Menlo Park
Because the system doesn’t run enough to flush itself out. In Menlo Park’s mild coastal climate, Lennox air handlers idle for long stretches, and attic dust, oak pollen, and leaf debris settle into the return plenum and evaporator coil. When the system does cycle, it pushes that stale air through the house. The fix is a return duct cleaning and coil inspection, not just a filter change. Call (833) 620-7085 to schedule a video inspection and see what’s actually sitting in there.
Yes. We do it regularly in Sharon Heights and West Menlo Park, and the process starts with video scoping to map the runs and find the access points. We hand-dig those spots rather than disturbing the blown-in blanket, clean with Rotobrush contact tools and Nikro HEPA negative-air containment, then re-seal any joints we disturbed. The insulation stays intact, and the duct runs get truly cleaned instead of just dusted from a single register.
It means the return side of your system is working as a leaf and pollen collector. For Lennox service in North Fair Oaks, this is especially relevant. Menlo Park’s mature oak canopy drops constant debris through roof vents and soffit gaps, and an attic-mounted Lennox handler pulls that material straight into the return plenum. Cleaning has to address the plenum and the upstream return runs, not just the supply side. We also check the intake screens and vent boots for gaps, because cleaning is temporary if the entry point stays open.
Sometimes. If the heat exchanger is sound and the cabinet is structurally intact, sealing the plenum and trunk joints with mastic and cleaning the full duct system extends the equipment’s life by years. But when a Lennox furnace from the 1960s or 1970s shows a cracked heat exchanger or a corroded coil cabinet, we’ll tell you replacement is the better spend before you put more money into ducts connected to dying equipment. We’ll show you the video and let you decide.
It shows what’s really connected to your Lennox trunk line after a remodel. We see disconnected flex collars, undersized runs feeding bonus rooms, taped joints that have opened under insulation, and debris accumulation at every transition point. You get the footage, so you can see exactly what we’re cleaning and whether the addition was ducted correctly in the first place. Most Menlo Park clients tell us this is the first time anyone showed them what’s inside their walls.
