If you live in an older home, your ductwork might not be adequate for modern high-efficiency HVAC systems. Ducts and their related parts—seams, seals and joists—begin to deteriorate 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 shifts over the years can cause it to pull apart and leak. Leaks can hike your heating and cooling expenses and cause poor indoor air quality. Separated ducts can bring in and circulate pollen, dust and other impurities.
Your attic, crawl space, garage or other uninsulated space could house some of your ductwork. Moisture can appear during high temperatures, causing rust to eat through the metal.
5 Signs You Need to Replace Your Ductwork
