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.
Air Duct Cleaning Company in Portola Valley, CA
Air duct cleaning in Portola Valley costs between $450 and $1,300 for a whole-system clean, depending on home size and how much the ductwork has collected over the years. Homes here run larger and more irregular than Peninsula tract housing, so we quote by system, not by the vent. If you’re calling from Portola Valley, you can reach our team at (323) 918-4345 for a written estimate before anyone starts work.
Why Portola Valley Homes Are Different
Portola Valley isn’t a place where two houses share a wall or a standard floor plan. Most of the homes here are large-lot, custom or semi-custom ranch and hillside builds from the 1960s through the 1980s, and many still run their original or early-replacement flexible ductwork through unconditioned crawl spaces that sit close to moist, wooded hillside soil. That means every duct system is a little different. We don’t send a crew with a one-size-fits-all checklist. We send technicians who expect irregular layouts, longer access runs, and duct paths that hug grade where damp air lingers.
The San Andreas Fault runs directly through town, and that fact shows up in HVAC work more than people expect. Ground movement from even modest Bay Area earthquakes shifts duct connections, opens gaps at flex-duct collars, and pulls unconditioned crawl-space air straight into the living space. After any shake above roughly M3.5, it’s worth having the boots and register collars checked, because a gap that was sealed tight a month ago may not be now. Add the dense oak and bay woodland loading intake air with pollen and fine organic debris, plus coastal fog that keeps crawl spaces humid far longer than in Palo Alto to the east, and you get duct systems that need a more careful, slower diagnostic pass than a standard Peninsula tract home.
Our Main Portola Valley Services
Portola Valley homeowners call us most often about two things: the air ducts that move heated and cooled air through the house, and the dryer vent that carries lint and moisture out of it. Both are covered below, each with its own dedicated Portola Valley page.
Air Duct Cleaning in Portola Valley
Air duct cleaning here means working around the realities of Portola Valley construction: long flex-duct runs, crawl-space access, and connections that may have shifted after seismic activity. We use truck-mounted and portable equipment from brands like Rotobrush and Abatement Technologies to pull accumulated debris from the full duct path without tearing up your home. On hillside lots with ground squirrels and roof rats active near the foundation, a proper seal at every boot and collar matters as much as the cleaning itself. See the full breakdown on our Air Duct Cleaning in Portola Valley page.

Dryer Vent Cleaning in Portola Valley
Dryer vents in Portola Valley often run longer than code minimums, routed through crawl spaces or out through hillside walls where lint can accumulate faster than homeowners realize. Wooded lots mean more organic debris near exterior vent terminations, and the fog that rolls in off the Pacific keeps that debris damp and sticky. A thorough cleaning removes the lint, checks the entire run for blockages, and verifies the termination point is clear and properly covered. Details specific to Portola Valley homes are on our Dryer Vent Cleaning in Portola Valley page.

Air duct cleaning is interior work that doesn’t require a town permit in Portola Valley. Some neighborhood associations restrict service-vehicle parking or exterior work hours; we arrive in modest vehicles and keep equipment quiet enough for nap schedules, so this rarely comes up in practice.
Yes. After any Bay Area earthquake above roughly M3.5, we recommend a connection check at every boot and collar. With the San Andreas Fault running directly through Portola Valley, a small shake can open a gap that pulls crawl-space air into the house. Sealing those connections is quick, inexpensive, and part of what makes a Portola Valley duct clean actually hold up.

What Portola Valley Customers Say
"New house, old dusty ducts. They were gentle in the house, laid down drop cloths, and double checked every register was sealed back up. Air smells fresh now."
- Scott Hemmings"Friendly, calm crew that clearly cared about the house. Covered their shoes, protected the floors, and double checked they'd closed up every vent cover properly. Would have them back."
- Omar Zaid"Ducts and dryer vent both. They put runners down the whole hall and wore booties. Spotless after, and they showed me photos of what came out. Worth every penny."
