How do I eliminate the moisture coming of my hvac ducts?

Asked by Rose
Centre, AL

the crawl space has plastic on the dirt and the trussed floors have a aluminum (feels like a plastic bubble wrap) attached and the hvac ducts are wrapped too.

There are a few options. The first is consider going with a sealed crawl after the space is dried out.

The second and less costly option is to have the ducts tested and air sealed followed up by having them insulated to R8 which meets the state's new Energy & Residential Code. As for the bubble wrap, I hear it is good as a packing material.
