Duct Repair & Sealing in Huntsville: what's different

Older homes often sit on crawl spaces with ducts underneath, while newer homes are slab or crawl-space construction with attic air handlers. Heat pumps are the most common system, and many homes have two units.

Another local pattern worth mentioning to the tech: crawl space humidity. Damp crawl spaces under older homes can damage duct insulation and lead to mold.
