Duct Repair & Sealing in Des Moines: what's different

Most homes have full basements with gas furnaces and central AC. Pre-war homes may have small ducts, limited return air or hot-water boilers, while suburban homes built since the 1990s typically have high-efficiency furnaces vented with PVC pipe through a side wall.
