If you live in an older home, your ductwork might not be sufficient for up-to-date high-efficiency HVAC systems. Ducts and their related parts—seams, seals and joists—begin to break down around 15 years. They reach their maximum life span around 20 to 25 years.
Ductwork also expands and contracts throughout the year. These movements over the years can cause it to separate and allow air to escape. Leaks can drive up your utility costs and lead to poor indoor air quality. Separated ducts can draw in and circulate pollen, dust and other impurities.
Your attic, crawl space, garage or other uninsulated space could contain some of your ductwork. Water buildup can appear during periods of high humidity, causing rust to eat through the metal.
