Air Duct Mold Removal in Bonita Springs, FL

Air duct mold removal in Bonita Springs homes

Attics here stay hot and wet most of the year. Cold supply air moves through R-6 and R-8 flex a few feet away. Where the insulation is torn or compressed, the inner liner sweats. Older block homes east of Old 41 and along the Imperial River sometimes still run original ductboard or bare metal in shallow attics. Mold does not eat fiberglass or the plastic liner. It eats the dust film sitting on them, once that film stays damp.

So the first job is finding the wet. Usually it is not the duct at all. It is the blower wheel or the evaporator coil face. Sometimes a drain pan overflows and stains the plenum beside it. Seasonal homes held at 78 to 82 for months grow biofilm in the air handler while nobody is home.

Then the porous-material rule decides the work. Hard metal and flex liner clean by source removal under negative pressure. Fiberglass liner and ductboard that is stained through or shedding does not clean. It gets cut out. Encapsulant painted over wet fiberglass hides it for a season.

Disconnected boots above ceiling registers pull raw attic air in. Reseal those, or the growth comes back.
