Air Duct Repair in Lakeland, FL

Air duct repair in Lakeland attics

One room never cools. There is a brown ring on the ceiling. You might hear insulation rustling at the register. These are duct failures, not thermostat problems. A flex run usually pulled loose at the boot. It is now blowing conditioned air into blown-in attic fiberglass. The same gap drags that fiberglass back toward the return.

Most Lakeland homes from the 1980s on use R-6 or R-8 flex on sheet-metal or ductboard plenums. The failure points are predictable. Inner liners delaminate and sag. Cores tear where someone stepped near a truss. Mastic dries out at collars and the tape lets go. Older downtown-era houses retrofitted for central air often have bare galvanized trunks with joints that were never sealed at all.

Sweating is the other call we get. Supply surfaces sit near 55F while the attic stays humid, so condensation forms where insulation got compressed, torn, or wet after a roof leak. Repair there means replacing the jacket, not wrapping tape over it.

Fiberglass ductboard that absorbed storm water is different. Once it is saturated, mold grows inside the board and cleaning does not fix it. Those sections get cut out and replaced.

We check static pressure and the evaporator coil before calling a duct the culprit.
