Air Duct Cleaning in Los Altos Hills, CA

No. On the sprawling single-level footprints common here, each zone is its own system, and it's normal to clean one at a time. That said, zones usually share the same history. If the attic runs over the west wing are full of dust and degraded flex, the under-floor runs serving the rest of the house are rarely in better shape. We'll walk each air handler, pull a few returns, and tell you which zones need work now and which can wait a season.

Rodents and wildlife in attic and crawlspace duct is routine in Los Altos Hills, and cleaning alone isn't the answer when there's active entry. Flex duct gets chewed through, insulation gets nested in, and contaminated material needs removal rather than agitation. We inspect the full run, show you where the duct has been breached, and separate what can be cleaned and sanitized from what has to be replaced. Sealing the entry points is pest work, and we'll say so plainly rather than cleaning around a problem that's going to come right back.

It helps with what settled, which is the part people keep re-breathing. Being in the wildland-urban interface means smoke gets pulled in through the building envelope and the return side, and fine ash ends up in the supply trunks, boots and on the blower wheel. Cleaning that out stops the system from redistributing it every time a zone calls. It does nothing about future smoke events (that's filtration and sealing), but clearing the accumulation is a reasonable step after a bad season, and the blower wheel in particular is worth checking.

Most of these houses date to the 1950s through the 70s, and even the ones rebuilt since often kept original attic routing. The common finding is flex duct that's been cooking in an attic that gets brutally hot each summer: the inner liner goes brittle, the outer jacket cracks, and sections sag or disconnect over long runs. Add heavy spring oak pollen, year-round leaf litter, pool and unpaved-drive dust pulled in through leaky returns, and you get loaded ducts plus rooms at the far end of a run that never quite condition. We flag what's cleanable versus what's past saving instead of cleaning duct that needs to be replaced.
