Air Duct Cleaning in East Foothills, CA

Up against the Diablo Range you're living next to dry grassland and chaparral, not forest, so the material in the air is fine mineral soil dust plus grass and foxtail pollen through the dry months. Wind coming off the hills pushes that into the house, and in most East Foothills homes the easiest path is the return chase and the attic duct, not the windows. If a return panel isn't sealed to the framing, or an attic run has pulled loose at a collar, the system draws in unfiltered air from the attic or wall cavity and redistributes it. Cleaning the ducts removes what's already settled inside, but if nobody addresses those gaps you'll see dust on surfaces again quickly. We look for the leaks while we're in there and tell you what we find, because cleaning alone won't fix an intake problem.

Usually yes, but the order matters. On the open-space edge here, rodent activity in crawlspaces and attics is common, and flex duct is easy for them to chew through. If we open a system and find droppings, nesting material, or a torn section with insulation pulled out, cleaning that duct just moves contaminated material around. What we'd do is clean what's sound, show you photos of what isn't, and recommend the damaged sections be replaced and the entry points sealed before we finish. Doing it the other way around means you pay for cleaning and then have the same problem a few weeks later. Tell us on the phone what you've heard or seen under the house so we bring the right crew and enough time.

East Foothills is a short run for us off the northeast side of San Jose, so scheduling is generally not the bottleneck. The thing that moves our calendar is weather. The first real heat wave of the season and the first week people switch the system back on tends to fill the book, and so does any stretch of smoke in the valley. If you call during a mild week you'll typically get a slot within a few days. If your system is down or you're smelling something off, say so when you call; we triage those ahead of routine maintenance cleanings.

The postwar ranch tracts here often still have original or early-replacement sheet metal trunks with branch runs added later, and the cooling season in this part of the county is long and hot enough that those systems run hard for months. What we see most: tape and mastic at the joints dried out and failed, so the connections are leaking into the attic; flex duct sagging between supports on sloped-lot attics and crawlspaces where runs are long; return chases built into the framing that were never properly sealed; and registers that were painted over at some point and no longer seat right. Add rodent damage on the open-space side and smoke intrusion from the 2020 SCU Lightning Complex that settled into some systems, and you get a fair amount of variety house to house. We inspect before quoting for that reason.
