Air Duct Repair in Tampa, FL

When one bedroom never cools and the attic hatch feels damp

The far bedroom is the usual complaint. Flex duct is the usual cause. Since about 1980, nearly every Tampa attic branch run is flex, and it sags between supports. A long belly or a kink over a truss chord kills airflow to that room long before the equipment is at fault. So does a crushed section at the boot. We pull the run tight, support it with wide saddle hangers at close spacing, and shorten the excess instead of coiling it.

Disconnected boots are the second thing we find. The collar separates, and the supply dumps into the attic while the return pulls attic dust and loose fiberglass back into the house. Tape alone does not hold here. Mechanical fastening plus mastic does.

Older galvanized trunks in crawl spaces and attics usually need seam sealing, not replacement. Fiberglass duct board plenums are different. Summer latent load keeps them damp, and once the interior liner holds microbial growth it cannot be scrubbed clean. That section gets rebuilt. Sweating supply plenums and bare boot collars get insulated so condensation stops staining ceilings.

Scope depends on attic clearance and duct board condition. Sometimes the layout itself is starved. Check your registers with a tissue before calling.
