Air Duct Mold Removal in Tampa, FL

What air duct mold removal actually involves in Tampa

Most Tampa homes built since about 1980 run flex duct branches through a vented attic. That attic stays humid all summer. Conditioned air at the boot collar meets that moist air, and the dew point does the rest. Fiberglass duct board plenums and transitions are the usual first casualty. So is the coil and drain pan under a continuous latent load.

Here is the part competitors skip. Mold on porous surfaces does not wipe off. Duct board interiors and flex liner are fiberglass. Cleaning tools shed the fiber and leave the roots. Those sections get cut out and replaced, not scrubbed. Bare galvanized trunks from the 1950s-70s are different. Metal can be brushed, vacuumed under negative air with HEPA, and recoated.

Fogging a sanitizer through a moldy system treats the symptom. It regrows. We look for the water first: a disconnected boot, an uninsulated collar sweating, a torn plenum seam, a roof leak above the air handler, a clogged condensate drain.

Signs worth checking yourself: black speckling at supply registers, a musty odor that spikes when the blower starts, visible moisture on the plenum. Pull the filter and look at the blower wheel.
