Lennox Air Duct Cleaning in Palo Alto, CA
We clean and repair Lennox air duct systems throughout Palo Alto, and we’re independent – not factory-authorized, which means we answer to you, not a manufacturer’s service quota. Learn more about our Air Duct Cleaning in Palo Alto. The thing that separates our Lennox work here is straightforward: in Palo Alto’s older housing stock, a huge share of duct problems trace back to abandoned galvanized runs from remodels long past, and most cleaners never look for them. Call (866) 528-3938 and we’ll actually put a camera in your ducts before touching anything. Our team knows Lennox equipment from the Merit Series up through the Dave Lennox Signature Collection, and we show up with Rotobrush and Nikro systems, not shop vacuums.
Why Palo Alto Residents Choose Us for Lennox Service
We’ve worked on Lennox systems in Palo Alto long enough to know which duct layouts keep showing up here, and which Lennox components fail because of them. Older bungalows near downtown and Professorville were built before forced air existed. Their Lennox air handlers got retrofitted into crawlspaces decades later, often through kneewalls, and the connections are usually the weak link. What we bring is specific: video inspection before any cleaning, OEM Lennox parts where they matter, and aftermarket flex and mastic where they actually hold up better in Palo Alto’s crawlspace conditions.
Dave Hanson, our owner, grew up in Shoreline West over in Mountain View and went through the HVAC program at Foothill College. He’s spent the years since learning what actually fails inside duct systems across Santa Clara County, and he built this company around negative-pressure cleaning that pulls debris out rather than loosening it. When we recommend Lennox sales & service work, it comes from someone who has opened enough plenums to know when a repair makes sense and when it doesn’t.

Common Lennox Air Duct Cleaning Problems We Solve in Palo Alto
- Disconnected Flex Duct at the Plenum. In 1900s – 1930s bungalows around downtown Palo Alto, Lennox air handlers retrofitted into crawlspaces often connect to flex that’s torn at the collar from moisture and rodents. This pulls crawlspace air straight into the return. We reconnect with new flex and seal with mastic.
- Coated Evaporator Coils and Blower Wheels. Palo Alto’s dry season runs from late spring into fall, and with the constant remodeling in this city, fine construction dust finds its way into return ducts. That dust coats Lennox coils and blower wheels, cutting airflow and making the system run hotter than it should. A duct cleaning that skips the coil leaves half the problem in place.
- Collapsed 1950s – 70s Flex in Mid-Century Ranchers. South Palo Alto has a large stock of Eichler-influenced and 1960s ranch homes with attic ducts. The original flex attached to Lennox plenums has often collapsed or torn at the collar after decades of summer heat baking the low-slope roofs. Conditioned air ends up in the attic.
- Musty Odors During Cool Damp Winters. Crawlspace moisture migrates into floor registers and Lennox ductwork from late fall through early spring in Palo Alto. When the system runs, that musty air circulates through the house. Root cause is often a disconnected return pulling crawlspace air, not just dirty ducts.
- Construction Dust from Remodels. A remodel upstream of your return registers sends drywall dust, sawdust, and paint overspray into the Lennox duct system. In a city as remodel-heavy as Palo Alto, we see this constantly. It requires full negative-pressure cleaning, not just a quick pass with a brush.
Lennox Service in Palo Alto: What Local Conditions Mean for Your Equipment
Here’s what makes Palo Alto genuinely different from Mountain View, Cupertino, or Redwood City: the huge stock of century-old bungalows and Craftsmans near downtown and Professorville was built with no ductwork at all. Forced air came decades later, often as a retrofit squeezed through crawlspaces and kneewalls. What we find repeatedly in these homes is an original Lennox plenum connected to a galvanized run that a prior remodeler simply abandoned in the crawlspace after a kitchen or addition project. The old run never got removed. The newer flex got spliced into what remained, and somewhere along the line a connection failed or was never properly made. The homeowner has a Lennox system blowing conditioned air into the dirt under the house. You can’t see it from the register, you can’t hear it, and the system keeps running. That’s why we don’t clean Lennox ductwork in older Palo Alto neighborhoods without first running a video inspection of both supply and return. If we find disconnected runs, cleaning alone would just blow more air into the crawlspace. The fix starts with reconnecting and sealing, then we clean what’s actually connected.
Last month in Professorville we inspected a 1920s Craftsman with a Lennox Elite air handler tucked into the crawlspace. The return duct was torn completely from the plenum. The supply trunk had a branch disconnected under the kitchen addition. We sealed both with mastic and new flex, then cleaned the evaporator coil that had been swallowing crawlspace dust for years. The homeowner noticed stronger airflow the same day, and the musty smell was gone.
Lennox Models & Products We Service in Palo Alto
We service Lennox Merit Series furnaces and air handlers, Elite Series variable-speed air handlers, and the Dave Lennox Signature Collection including the SL280V. We also work on Lennox 13ACX and 14ACX air conditioners when duct issues have affected coil performance. On critical components like blower motors and control boards, we use OEM Lennox parts. For duct connections, collars, and sealing, we use high-quality aftermarket flex and mastic that handle Palo Alto’s crawlspace moisture and attic heat better than the original materials. Because we work primarily in Palo Alto, Los Altos, and the surrounding cities, we keep common replacement parts on the truck, which means less waiting when your system is down.

AfterLennox Service Pricing in Palo Alto
Duct cleaning in Palo Alto typically runs between $395 and $850 for an average single-family home, depending on the number of returns, supply runs, and whether we’re also cleaning the evaporator coil and blower. Video inspection before cleaning is standard on our jobs in this city, because older Palo Alto homes hide disconnected runs that change the scope of work. When we quote, it’s one flat price per system agreed before work starts, not a per-vent figure that grows once we’re inside. A free estimate includes the camera inspection, so you’ll know what’s actually in your ducts before you commit. Call (866) 528-3938 and we’ll schedule it.

FAQs – Lennox Air Duct Cleaning in Palo Alto
Musty smells in Palo Alto winters usually mean crawlspace moisture is being pulled into your Lennox return through a torn or disconnected flex connection at the plenum. The damp crawlspace air gets distributed through the house every time the system runs. We locate the disconnect with a video inspection, reseal with mastic, and clean any affected duct sections. If the smell has been persistent for multiple seasons, call (866) 528-3938 and we’ll find the source.
No, collapsed flex can’t be cleaned because the inner liner has lost its shape and airflow has already been compromised. The right fix is replacing that flex run and sealing the new connection at the collar. In Palo Alto’s older bungalows, we often find several collapsed runs strung together from different eras. We replace what’s failed and clean the rest of the connected system so you’re not paying to clean duct that’s blowing into the crawlspace.
In most Palo Alto neighborhoods, every 3 to 5 years is reasonable, but if you’ve completed a remodel, had a foundation repair, or live near active construction, you’re likely due sooner. Construction dust is fine enough to coat blower wheels and evaporator coils within a single project. We recommend cleaning after any major remodel, not years later. If you’ve never had a video inspection done on an older home, call (866) 528-3938 and we’ll show you what’s actually in there.
Duct cleaning does not void a Lennox manufacturer’s warranty. The warranty covers the equipment, not the ductwork, and a professional cleaning with proper negative-pressure equipment protects your air handler and coil from debris buildup. We’re an independent provider, so our work doesn’t tie into any factory authorization either way. If you’re concerned about a specific Lennox component, call (866) 528-3938 and we’ll walk through what’s covered before we start.
Yes, we service all major brands across Palo Alto service area homes, but our crew has deep familiarity with Lennox because of how many we see in this city. Older Lennox retrofits, in particular, have patterns we recognize immediately. Whether it’s a Merit Series air handler in a south Palo Alto rancher or an SL280V in a Professorville Craftsman, the approach is the same: inspect first, explain what we found in plain terms, then clean or repair what’s actually needed. Clean air isn’t a feeling – it’s what’s left after the debris is out.
