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 Los Altos Hills, CA
Air duct repair in Los Altos Hills usually means working on custom homes built into hillsides, where long duct runs snake through attics and crawlspaces and age faster than the systems you’ll find down on the valley floor. We’re Air Duct Cleaning Palo Alto, and we’ve served Los Altos Hills since 2016 with professional-grade Rotobrush and Nikro equipment, not consumer-grade blowers. Call (833) 620-7085 when your ducts need more than a surface clean.
Why Los Altos Hills Homes Are Different
Los Altos Hills is a semi-rural town of large-lot estates and winding private lanes. Most air duct jobs here are on custom homes running 3,000 to 8,000 square feet with multiple HVAC zones, long duct runs, and equipment tucked into attics or crawlspaces. These aren’t the tract-home layouts you’d see in neighboring Sunnyvale or Mountain View. Many homes date from the 1960s through 2000s, with some newer rebuilds, and construction often includes multiple air handlers and flex duct in attics. Long runs accumulate debris differently than compact suburban homes do, which means a standard cleaning pass won’t reach what’s actually sitting in the far end of a 60-foot return.
The foothills climate adds another layer. Hot, dry summers drive heavy AC use from June through September, pulling dust and pollen into returns. Wildfire smoke episodes from the surrounding hills push fine ash into open-rafter great rooms, and the ducts pick up oak and eucalyptus debris that settles on roofs and vents during fire season. On many hillside properties, the HVAC returns pull from those same open-rafter spaces, so whatever lands on the roof finds its way into the system. It’s a pattern technicians don’t see on the valley floor, and it changes how we approach both cleaning and repair work here.

Our Main Los Altos Hills Services
Los Altos Hills homeowners call us most often about two things: air duct cleaning and dryer vent cleaning. Both involve professional-grade equipment and both respond to conditions that are specific to this town.
Air Duct Cleaning in Los Altos Hills
Air duct cleaning in Los Altos Hills means working around long flex-duct runs, multiple air handlers, and the fine ash and organic debris that foothills winds push into returns. We use Rotobrush contact-cleaning systems to dislodge compacted debris and Nikro HEPA negative-air machines to capture particulates during the work, so nothing cross-contaminates your living spaces. Households with allergy sufferers, infants, or elderly residents notice the difference quickly, especially after a smoky fire season. For the full scope of this service, see our dedicated page on Air Duct Cleaning in Los Altos Hills.
Dryer Vent Cleaning in Los Altos Hills
Dryer vent cleaning in Los Altos Hills is a fire-prevention service first and a convenience second. Long vent runs through hillside foundations and tight laundry closets accumulate lint differently than short, straight runs in newer valley homes. We treat every dryer vent job as a fire-code-aligned safety service, not a cheap upsell. Lint buildup is the leading cause of dryer fires, and on large-lot properties the vent often exits through a roof or a long sidewall run that homeowners never see.

Air Duct Repair in Los Altos Hills
Air duct repair in Los Altos Hills is common on homes built between the 1960s and 2000s, where decades of thermal cycling and hillside settling have taken a toll on joints, flex duct, and return plenums. Long runs through attics and crawlspaces mean a single separated joint can pull debris, humidity, and pest residue into the system, and the problem only worsens during fire season when fine ash finds every gap. We close that gap with the same professional-grade approach we bring to cleaning, including full Air Duct Repair so homeowners aren’t left with a clean system that leaks.
Ductwork Repair
Signs you need it
Rooms that never reach the thermostat setpoint, whistling near registers, or a sudden spike in dust after windy weather all point to leaking or separated ductwork on a Los Altos Hills hillside home.
What it costs in Los Altos Hills
Ductwork repair in Los Altos Hills typically runs $300 to $900 depending on access, with attic and crawlspace work on hillside lots at the higher end due to longer runs and tighter clearances.
How we do it
We locate the failure with a pressure test or visual inspection, seal or replace the damaged section using mastic and mechanical fasteners, and verify airflow before we leave the property.
Air Duct Replacement
Signs you need it
Crushed flex duct, rusted-through metal runs, or ducts that predate current code and show signs of mold, pest intrusion, or asbestos-era materials are replacement candidates rather than repair jobs on older Los Altos Hills estates.
What it costs in Los Altos Hills
Air duct replacement in Los Altos Hills typically falls between $1,800 and $4,500 for a partial system and $4,500 to $9,000 for a full custom-home replacement, reflecting long runs and multi-zone layouts.
How we do it
We size the new ductwork to the existing air handler, remove the failed runs, and install sealed, insulated ducting with proper support spacing and R-value appropriate for unconditioned attic spaces.
What Air Duct Repair Costs in Los Altos Hills
| Item | Typical range in Los Altos Hills |
|---|---|
| Ductwork repair (single section) | $300 – $900 |
| Partial air duct replacement | $1,800 – $4,500 |
| Full air duct replacement | $4,500 – $9,000 |
How long does air duct repair take in Los Altos Hills?
Most single-section repairs take half a day, while a full replacement on a large custom home can run two to three days. Access through hillside crawlspaces and multi-zone attics is usually what adds time.
Can you repair ducts without replacing the whole system?
Yes. In most Los Altos Hills homes we can seal or replace damaged sections without touching the rest of the system. We’ll only recommend full replacement when the ductwork is too deteriorated or poorly designed to justify repair.
Brands We Service in Los Altos Hills
We work on Honeywell and Aprilaire filtration products across Los Altos Hills, and our trucks carry common Aprilaire filter media so we can usually install or replace media in a single visit. Read more at our brands.
