If your home\u2019s central air conditioning system doesn\u2019t seem to cool like it used to, or you\u2019ve noticed rising energy bills despite regular maintenance, the problem might not be with your AC unit at all. Often, the issue lies in the ductwork, especially the insulation surrounding it.<\/span><\/p>\n

Central AC ducts carry cooled air from the air handler to various rooms in your house. If these ducts are poorly insulated or the insulation has deteriorated, you\u2019ll lose conditioned air to the surrounding environment, especially in attics, basements, or crawl spaces. This means higher energy bills, reduced comfort, and potential moisture issues. The good news? Replacing duct insulation is a DIY job most homeowners can tackle with the right materials and guidance.<\/span><\/p>\n
