Who We Are

Some duct systems cannot be cleaned back to good, and we say so on the spot. If the inner liner on your 1960s-80s gray flex has gone brittle and is shedding, brushing it just tears it up faster. That duct needs replacing, not cleaning. Same answer when we open a trunk and find cloth or asbestos-paper tape crumbling at the joints: we stop, we do not disturb it, and we tell you who tests and who abates. We also turn down work when the ducts are fine. If the interior is clean and the system is moving air the way it should, you will hear that, and the visit ends with photos and no invoice for cleaning you did not need. We would rather lose the ticket than sell you a service that changes nothing.

We work the South Bay / Peninsula corridor from San Jose up through Santa Clara, Sunnyvale, Mountain View, Palo Alto and the Mid-Peninsula, and the calls here follow a pattern. A six-month rainless stretch leaves fine valley dust and construction and roadway particulate suspended, spring loads the air with grass and oak pollen off the surrounding hills, and late-summer to fall wildfire smoke pulls PM2.5 into attic ducts through leaky returns and boots. Mild winters make the problem worse, not better. Systems short-cycle instead of running long, so whatever settles never gets purged. Add the marine layer pushing overnight humidity up and attics swinging from 130F-plus down to 50F, and you get moisture condensing on cooling supply lines in homes with undersized or sweating ducts. Valley floor homes on former orchard and bay-margin soils bring in different grit than foothill homes on dry grassland and oak woodland, and most Peninsula stock predates 1980. That means original sheet metal trunks or aging flex underneath all of it.

On site, the crew runs a truck-mounted vacuum with the collection unit outside, puts the house under negative pressure, and seals every register so debris travels one direction. Then we agitate, rotary brushes in rigid metal, air whips and softer tools in flex that can take it, and pull the loosened material out through the trunk line: supplies, returns, boots, and the plenum. We photograph before and after so you are not taking our word for it. We service Carrier, Trane, Lennox, Goodman, Rheem, and American Standard equipment. If the problem turns out to be a filter that has been in place too long, that is a filter replacement conversation. If smoke and attic dust are getting in through gaps at the boots and returns, duct sealing fixes the cause instead of the symptom, and dirty evaporator coils from years of unfiltered air usually need coil cleaning at the same time. Cost tracks the number of runs, how much of the system is flex versus metal, attic or crawlspace access, and whether we find smoke residue or moisture damage that adds work once the registers come off.
