Air Duct Replacement in Orlando, FL

When replacing ducts beats patching them again

"Can't you just repair the bad spots?" Often, yes. A torn outer jacket on a firm run gets taped and re-wrapped. A single belly between trusses gets re-hung. Replacement earns its place when the inner liner is shedding. It also applies when flex is crushed behind truss webs. Kinked branches from install are another sign; they never moved air to the far bedrooms.

Most Orlando houses from the 1970s through the 90s use a sheet metal trunk with flex branches. The trunk usually stays. Old collars come off. Takeoffs get re-sealed with mastic. New insulated flex is pulled with the slack taken out. Hangers are wide straps on the outer jacket, spaced so the run stays straight. No wire. No low spots to trap debris.

Pre-1970 block homes are different. Bare or internally lined rigid metal. Once that liner flakes, cleaning will not stop the shedding. Those runs get replaced or wrapped on the outside instead.

Boots and returns matter more than the duct body here. Uninsulated boots sweat into attic insulation and ceiling drywall. Framed return chases in stud bays pull unfiltered attic air. We seal boot to drywall. We address the bypass at the one-inch filter rack. Airflow gets checked at every register before leaving.
