Myth Buster Monday:
Myth: Once Your Ducts Are in Place, They’ll Always Be Good
It makes sense. Your ductwork is installed in the attic, behind walls, and completely out of reach. There are no moving parts, either. So, how could they ever “go bad?”
Fact: Well, it all depends on the type of material used. Flexible ductwork consists of insulation wrapped around a metal coil. Over time—or if the material was low quality to begin with—it can degrade and develop leaks. As previously mentioned, leaks can take a significant toll on your efficiency.
If your ductwork has gone a very long time without any kind of maintenance, it might be more cost-effective to have them replaced.
