A duct system in Commerce 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.
Many Commerce 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.
Small tremors are a fact of life in Commerce, and duct joints in attics and crawlspaces shift a little with each one. Over years, takeoffs loosen and seams open. A comfort problem with no obvious cause is worth a camera look at the connections overhead.
Raised-foundation homes around Commerce 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 Commerce, a cleaning from the main trunk out removes that stored residue, and the startup smell goes with it.

Our negative-air machine seals onto the main trunk duct and puts the whole system under suction first.
