A duct system in Pacifica may face wildfire smoke, valley heat, coastal moisture or all three across the year. This is what we actually find here, and what we check on every visit.
Smoke is the finest dust there is, and during fire season it penetrates homes across Pacifica even with windows shut. The duct system collects it in the trunk and returns, and after the skies clear the house keeps recirculating that residue - and its smell - until the system is cleaned from the trunk out.
Many Pacifica neighborhoods carry duct systems installed decades ago - undersized returns, unsealed seams, runs that were never insulated. The equipment may have been replaced twice while the ducts stayed original, and the inspection shows what that means for airflow and dust.
California's mild months are open-window months, and everything outside - pollen, road dust, construction grit - comes in and a share of it settles into the returns. By the time the house closes up for summer heat or winter rain, the system has stored a season of it.
Raised-foundation homes around Pacifica run ducts through crawlspaces that stay cool and damp. Insulation sags, joints sweat and dust inside the runs sits in moisture - the musty startup smell in these homes is a crawlspace duct story more often than not.

Because the ductwork kept it. Fine smoke particles settled into the dust inside your trunk and returns during the event, and every cycle since has released a little back into the rooms. In Pacifica, a cleaning from the main trunk out removes that stored residue, and the startup smell goes with it.
It removes the indoor reservoir: smoke that settled into duct dust keeps recirculating long after outdoor air clears. Cleaning the trunk and returns, plus a fresh high-quality filter, is the combination San Mateo County homeowners use to close out a smoke season indoors.
Usually the run serving it: a separated attic joint, a kinked flex run, or a conversion room tied into an undersized trunk. In Pacifica we trace the run on the inspection camera, and repair, sealing or a properly sized new run fixes it at the cause.

No — and be wary of anyone who does. Every duct system is a different size and condition, so a phone price is a guess that changes at your door. Our inspections and estimates are free: a tech looks inside your actual ductwork first, then gives you one clear price before any work starts.
