Air Duct Replacement in San Mateo, CA

When does duct replacement beat another cleaning?
Cleaning fails when the duct itself is the problem. Flex with a torn jacket cannot be brushed back to health. Rodent damage under raised foundations near the creeks and baylands usually means the run gets pulled, not scrubbed. Same with flex that sagged off its hangers and pooled in the belly. Moisture sits in that low spot. Insulation stays damp. Replacement with properly spaced hangers and a short, straight path fixes it.
Old metal is different. Galvanized rectangular trunks from the fifties and sixties are often sound. The failures are at the joints, the boots, and the panned floor-joist returns that were never sealed. Those cavities pull air from crawlspace and wall voids. Replacing a panned return with hard duct or lined flex stops that directly.
Watch for asbestos tape or jacket on 1920s-40s gravity octopus trunks. That is abatement work, handled by a licensed abatement contractor, before anyone touches it.
Replacement also solves what cleaning never does: undersized returns, crushed branch runs behind a remodel, filter slots with no gasket. Measure the return grille. If it looks small for the furnace, no new duct downstream will help.
Work happens in crawlspaces and attics. Access drives the schedule more than duct footage.
What Happens After You Call Us
Call and tell us what you're seeing, dust on the registers, weak airflow in the back bedrooms, a dryer that needs two cycles. We book a two hour arrival window and text you when the van is twenty minutes out.
We open the furnace closet, pull a register or two, and look at the crawlspace or attic runs first. The estimate is free, and you get one firm number for the supply and return count we actually find.
We clean the lines, check airflow at each register, vacuum up anything we tracked in, and show you before and after photos. You pay the number we quoted, even if the crawlspace runs longer than expected.
