Why it matters to you
Lowcountry homes do have legitimate triggers — renovation dust, rodents in crawlspace ducts, flood water that reached the ductwork, or mold from humidity. But aggressive cleaning of fragile older flex duct or duct board can tear liners and create new leaks.
Practical guidance
Ask to see photos or camera footage of the problem before paying for cleaning, and be wary of very cheap phone offers. If mold or debris is found, fix the cause — leaky returns, crawlspace moisture, or missing filtration — or the problem will return.
