The answer to 'lifespan of ductwork' is that properly installed and maintained ductwork can last 15-20 years or more. Ductwork is a critical component of your home's HVAC system, responsible for distributing heated or cooled air throughout your home. With proper care and occasional repairs, your ductwork can continue functioning efficiently for many years.
Several factors can impact the lifespan of ductwork, including the quality of the initial installation, the materials used, and the environment the ductwork is installed in. Ductwork located in attics, crawl spaces, or other unconditioned areas may have a shorter lifespan due to exposure to temperature extremes and moisture. Regular maintenance, such as sealing leaks and cleaning the ducts, can also help extend the life of your ductwork.
