Duct Sealing in Auburndale, FL

Duct sealing in Auburndale homes

The back bedroom never cools. The hallway register barely moves air. Dust films the furniture a week after cleaning. These symptoms usually trace to the same place. Air is leaving the duct system before it reaches the room. In attic runs, a boot that has pulled loose from its register take-off dumps cold air into the attic. The system then makes up that volume by pulling attic air back in. That is where the sand, fiberglass fragments and gray dust come from.

What gets sealed depends on what you have. Older block homes around town often run galvanized trunks with duct board plenums. Seams there rust where condensation sits. Mastic goes on the seams, not tape. Tape lets go in attic heat. The 1980s and 90s stock uses duct board boxes and R-4 or R-6 flex. Newer slab builds use R-6 or R-8 flex on metal collars, and the collar connection is the usual failure point.

Sealing does not fix everything. Sagging flex, kinked runs and an undersized return are airflow problems, not leakage problems. A dirty blower wheel reads the same at the register.

Torn vapor jacket gets repaired or the branch gets replaced. Wet insulation does not dry in an Auburndale attic.
