Who We Are

Elk Grove is mostly post-1985 subdivision stock, and that tells us what we'll find before we open the attic hatch: insulated flex duct running through unconditioned space, held up by straps, branching off a sheet metal plenum at the air handler. Those attics hit 130–150°F in July. Over fifteen or twenty years the inner liner degrades, compressed takeoffs loosen at the collar, and long runs sag into low traps where dust packs and stays. In the older pockets closer to the central city you get something different: pre-1960 sheet metal in vented crawlspaces or shoehorned into tight attics, and 1950s–70s ranch tracts with early fiberglass ductboard plenums feeding metal branches. Ductboard handles brushing differently than flex, and flex handles it differently than rigid metal. We adjust the method to what's actually in the house. Two-story homes with attic-mounted equipment get an extra look, because a cold supply plenum sitting in hot attic air will sweat anywhere the insulation has gapped, and wet dust is a different problem than dry dust.

Systems here run long cooling cycles at high static pressure for five months, then a short heat window from December through February. Annual runtime is high and the duct load builds fast. The valley floor supplies the material: fine alluvial soil dust off surrounding row-crop and rice ground, spring grass and oak pollen, olive and mulberry pollen in the older urban streets, and wildfire smoke from the Sierra and Coast Ranges from August through October that pulls in through return leaks and settles in the trunk lines. Winter inversions and tule fog hold PM2.5 near the surface for days at a time. The common calls look like this: dust on the registers a week after dusting, a burning smell the first time the heat runs in December, allergy symptoms that don't track with being outdoors, or a remodel that pushed drywall dust into the returns. On site we run a truck-mounted vacuum, seal every register so the system pulls negative, and work the lines with rotary brushes and air whips sized to the duct. We pull the blower compartment and clean it. We photograph before and after so you aren't taking our word for it. We work on Carrier, Trane, Lennox, Goodman, Rheem and American Standard equipment.

Sometimes we open a system and the ducts are clean. We tell you that and we don't clean them. More often the real issue is upstream: a filter that's the wrong size or hasn't been changed on schedule, which we handle at air filter replacement, or return leakage in the attic pulling unfiltered air and smoke straight into the system, which is a duct sealing job. If airflow is weak and the ducts are fine, the problem is usually at the evaporator coil. On cost, the things that move the number on a duct cleaning in Elk Grove are the count of supply and return runs, whether the equipment is in a low attic or a crawlspace that takes time to work in, whether we're dealing with degraded flex liner or ductboard that needs careful handling, and whether there's rodent or moisture contamination that changes the scope. We'd rather look first than guess from the driveway.
