If you live in an older home, your ductwork might not be compatible with modern high-efficiency HVAC equipment. Ducts and their related parts—seams, seals and joists—begin to break down around 15 years. They hit their maximum usability around 20 to 25 years.
Ductwork also expands and contracts throughout the year. These changes over the years can cause it to break apart and leak. Leaks can increase your utility costs and lead to poor indoor air quality. Separated ducts can pull in and circulate pollen, dust and other impurities.
Your attic, crawl space, garage or other uninsulated space could house some of your ductwork. Water buildup can form during the summer, causing rust to eat through the metal.
