HVAC Duct Cleaning in Los Gatos, CA

Why Los Gatos duct gets dirty in the first place

Most of it comes in from outside the house. Wooded and hillside parcels get rodent entry and nesting in both attic and crawlspace duct. Fine wildfire ash settles into returns during smoke season. Remodels leave construction drywall dust sitting in the trunk for years. Undersized or dirty filter racks on heat-only-era returns pass all of it straight through to the blower.

Method depends on what you actually have. Original galvanized sheet metal trunk-and-branch in postwar ranch homes takes brushing and negative air. Mid-century wrapped fiberglass ductboard does not (brushes tear the liner). R-6/R-8 flex in anything built or remodeled since the 1980s has to be handled gently or the inner core shreds.

Cleaning fixes dust. It does not fix sagging and kinked flex in attics killing static pressure, disconnected boots at register takeoffs dumping conditioned air into attics, crushed crawlspace runs, or condensation on cold supply runs. Deteriorated fiberglass liner shedding fibers is a replacement job. We will tell you that instead of vacuuming it.

Typical service interval here is three to five years. Shorter with pets, wood heat, mountain-road dust, or recent remodel work. Pull one register grille and look down at the boot yourself first.
