About Us

A job starts with the truck-mounted vacuum. We run the main hose to the air handler, cut or use an existing access port, and put the trunk line under negative pressure before anything else moves. Then the crew seals every supply and return register in the house so the system pulls from one direction only. From there it's mechanical agitation: rotating brushes and compressed-air whips fed down each branch run, working from the far end back toward the collection point, so debris travels into the vacuum instead of into the room. Returns come last because they hold the most. We open the blower compartment, check the coil face and the plenum, and show you what came out before we close up. Most single-system homes take three to five hours. We work on Carrier, Trane, Lennox, Goodman, Rheem, and American Standard equipment, plus the older mixed-vintage setups common around here where a newer condenser was tied into ductwork from a previous era.

The calls we get most in Santa Clara fall into a few groups. Dust on surfaces within a day of cleaning. A musty smell on the first heat cycle of fall. Visible debris at the register faces. Allergy symptoms that track with the system running. Post-remodel drywall dust, the single most common legitimate reason to call. And smoke season, when people notice ash on registers and want the returns cleared. Sometimes the answer is that the ducts are fine. If we scope the runs and they're clean, we tell you, and we don't clean them. What we often find instead is a filter problem or a leakage problem. A filter that's undersized or overdue lets dust bypass straight into the blower, and air filter replacement on a sane schedule prevents more buildup than cleaning does. Ducts pulling dirty crawlspace air through open seams will reload within months, which is a duct sealing job, not a cleaning job. Heavy ash or biological film on the evaporator face is coil cleaning, and cleaning ducts without addressing it accomplishes little.

South Bay/Silicon Valley air duct conditions are shaped by three things: a long dry season, a housing stock largely built 1945-1975 with ducts now 50-75 years old, and later AC retrofits layered onto heating-only duct designs. Valley floor soils are fine alluvial silt and former orchard ground; the summer dry months generate persistent fine dust that loads filters and settles in horizontal trunk runs. Spring brings heavy grass, oak and olive pollen off the surrounding Diablo Range and Santa Cruz Mountains, plus widespread ornamental street trees. Winter rain and cool Bay fog raise crawlspace humidity, and un-insulated or poorly sealed metal ducts under floors sweat and collect damp dust and mold-supporting debris. Late-summer and fall wildfire smoke events across Northern California push PM2.5 deep into return systems and leave fine ash residue in plenums and on coils. Systems here run many hours daily May through October and again on cold winter mornings, so filtration failures compound fast. Most valley homes benefit from duct inspection every 3-5 years, sooner after a remodel, roof work, or a heavy smoke season. On cost, the things that move the number on a duct cleaning here are the count of supply and return runs, whether there's one system or two, how much of the run is accessible versus buried in a tight crawlspace or a low attic, whether an access port has to be cut and patched, and the condition of what we find. Old flex duct with torn inner liner can't be brushed clean and we'll say so rather than charge you to agitate it.
