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.

AfterAir Duct Cleaning Company in Los Altos Hills, CA
Air duct cleaning in Los Altos Hills typically costs between $450 and $900 for a full-system job on an estate-sized home, and it’s usually completed in one visit. We’re Linden Air Duct Cleaning, and we’ve been serving homeowners since 2004 as part of the Threshold Group family. Los Altos Hills presents specific challenges most valley floor companies never deal with: long duct runs through unconditioned spaces, wildfire smoke residue, and custom 1960s-to-1990s systems that need real care. Call us at (980) 447-2498 and we’ll give you a written price before any work begins.
Why Los Altos Hills Homes Are Different
Los Altos Hills sits directly in the Wildland-Urban Interface on the lower slopes of the Santa Cruz Mountains, and that changes everything about how duct systems behave here. When the 2020 CZU Lightning Complex fire burned just southwest of town, the foothills sat under particulate-laden smoke for weeks. That smoke didn’t just drift past windows. It got pulled into return vents, pushed through filter media, and settled deep inside duct runs where standard filter changes never reach. We still open systems in Los Altos Hills and find a fine gray coating from that single fire event layered over older residue from years of wood-burning fireplaces.
The housing stock compounds the issue. Los Altos Hills developed almost entirely from the late 1950s through the 1990s as custom single-family estates on one-acre-minimum lots. Many of these are sprawling single-story ranch or contemporary designs with very long duct runs, often original or once-replaced flex duct routed through unconditioned crawl spaces and slab chases. The marine-layer fog that pushes east off the Santa Cruz Mountains hangs over these hills more persistently than in Sunnyvale or Mountain View, which means moisture in those unconditioned spaces rusts metal and feeds microbial growth that valley homes simply don’t see at the same rate.
Add the pollen load from Rancho San Antonio and Foothills Preserve, and you get ducts that look dramatically different from anything in a newer tract development. Oak and annual grassland pollen coats the interior surfaces. Wildfire particulates layer on top. Moisture binds it all together. Technicians who work the custom homes along Moody Road and the upper Robleda corridor regularly open systems that haven’t been properly cleaned since they were installed, and what they find inside is a genuine health and efficiency conversation, not just a maintenance checklist item.
Our Main Los Altos Hills Services
Three services cover nearly every duct-related issue Los Altos Hills homeowners face. Each one has its own dedicated page with local pricing, what the job involves on these specific hillside homes, and answers to the questions we hear most.
Air Duct Cleaning in Los Altos Hills
Full-system cleaning on a Los Altos Hills estate means negative-pressure extraction through every supply and return register, not just a quick vacuum at the visible vents. We set up HEPA-filtered negative-pressure equipment at the air handler, isolate each register, and physically agitate the duct walls to release adhered debris. On the long runs typical of these larger homes, that takes time and real equipment, which is why pricing reflects square footage and system complexity. We walk you through exactly what we’ll do and what it will cost before we start. See Air Duct Cleaning in Los Altos Hills for full local pricing.
Dryer Vent Cleaning in Los Altos Hills
Dryer vents in Los Altos Hills run longer and through more unconditioned space than in most cities, which means lint bypass the dryer’s own trap and accumulates faster than you’d expect. A clogged vent in a hillside home with a long run to the exterior is a real fire risk, and it also forces your dryer to work harder, which shortens the appliance’s life. We clean the full run from the dryer connection to the exterior termination point using professional rotary brushes and compressed-air tools. Pricing and specifics are on Dryer Vent Cleaning in Los Altos Hills.
Air Duct Repair in Los Altos Hills
Older custom systems leak. Flex duct from the 1970s and 1980s sags, tears, and separates at the joints, especially in unconditioned crawl spaces where temperature swings are extreme. That means air you’re paying to heat or cool is escaping into spaces nobody lives in. We repair the damage, reseal connections properly with mastic and UL-rated tapes, and document everything with before-and-after photos so you can see exactly what was done. Every repair comes with a written guarantee and a free second visit if the repair fails. Full details are on Air Duct Repair in Los Altos Hills.

- Cheryl A."Thorough job on all eleven vents and the main trunk. Took longer than the three hours they quoted, but he told me early and kept working. Air feels fresher."
