Air Duct Replacement in Bonita Springs, FL

Can torn flex be patched instead of replaced?

Sometimes. It depends which layer failed. Flex duct is three parts: an inner liner, a fiberglass core, an outer vapor jacket. A clean slice in the jacket can be taped and resealed. But once humid attic air reaches the cold liner, the run sweats from the inside. The core stays wet. Tape does not fix that. In a hot Bonita Springs attic, that duct is finished.

Crushed flex is the other common call. Roof and ceiling crews worked many low block-home attics after Ian. Runs get stepped on, kinked over a truss chord, or pulled off the boot entirely. The register still blows, just weaker, and the system runs longer. Hold a tissue at each register and compare rooms. Far bedrooms tell you first.

Replacement is not just swapping tube. Hard collars at the trunk, boots sealed to the drywall with mastic, runs strapped so they cannot sag into standing loops. Sag is where condensate collects.

What moves the job: whether the plenum and trunk are original ductboard with eroded liner, attic clearance over a low block ceiling, register count, and whether returns were undersized to begin with. Condo closet handlers with soffit and chase runs usually mean opening ceiling and coordinating with the building.
