Air Duct Repair in Orlando, FL

Air duct repair in Orlando homes

One bedroom stays warm all afternoon. The register barely moves a tissue. Maybe you see gray fuzz at the vent edges, or a brown ring on the ceiling drywall. Those are duct faults, not thermostat faults. The air conditioner is usually fine.

Most of it happens overhead. Flex duct in Orlando attics sags between trusses into long low bellies. Debris settles in those bellies. Strap over-tightening pinches the inner liner, and the far run starves while nearer rooms overcool. Torn outer jacket exposes the fiberglass core to attic air. We re-support, pull slack out, and reconnect at collars with mastic rather than tape alone.

Boots and collars sweat because attic air here is humid most of the year. Wet insulation at a boot stains ceilings and feeds mold. Cleaning a duct without fixing that insulation just resets the clock.

Returns deserve a look too. Many 1970s-90s houses use a framed wall chase as the return plenum, so it draws unfiltered attic and wall-cavity air. Builder-grade 1-inch filters also bypass at the rack. Sealing the chase matters more than anything done downstream.

In pre-1970 houses with internally lined rigid metal, degraded liner sheds fiber. Then replacement beats repair, and we will say so.
