When a heating or cooling system underperforms, the first instinct is often to blame the equipment itself—but what about the network of metal channels that carry conditioned air through a building? In the trades, ductwork is treated as a separate system with its own maintenance schedule, and ignoring it can lead to measurable efficiency losses. For homeowners in Northern California, where seasonal wildfire smoke and temperature swings add particulates to the air, a professional inspection of the duct network is a routine step, not an emergency repair.
One practical point to consider is the difference between cleaning and sanitizing. A standard vacuum-based cleaning removes loose debris, but if you have visible mold growth or a rodent intrusion, that requires a different protocol—often involving antimicrobial coatings and source removal. Ask any HVAC technician, and they’ll tell you that a simple brushing does not solve a biological problem. Before scheduling any work, request a camera inspection of the main trunk lines; this gives you a visual baseline and helps you avoid paying for a service that does not address the actual condition.
Another useful detail involves the relationship between duct sealing and cleaning. In older Bay Area homes, leaks in the duct joints can pull in attic insulation dust or garage fumes, making the ducts dirty again within months. A competent tradesperson will test static pressure and seal visible gaps with mastic or foil tape before or after cleaning—otherwise, you are just moving air through a sieve.
