If you live in an older home, your ductwork might not be sufficient for modern high-efficiency HVAC technology. Ducts and their related parts—seams, seals and joists—begin to break down around 15 years. They arrive at their maximum usability around 20 to 25 years.
Ductwork also expands and contracts throughout the change in temperatures. These changes over the years can cause it to break apart and lose air. Leaks can drive up your heating and cooling expenses and cause poor indoor air quality. Separated ducts can draw in and spread pollen, dust and other impurities.
Your attic, crawl space, garage or other uninsulated space could house some of your ductwork. Water buildup can appear during high temperatures, causing rust to eat through the metal.
