If you live in an older home, your ductwork might not be adequate for today’s high-efficiency HVAC systems. Ducts and their related components—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 pull apart and allow air to escape. Leaks can drive up your energy expenses and lead to poor indoor air quality. Cracked ducts can pull in and diffuse 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
There are several other hints that can indicate ductwork needs to be replaced:
1.Your ducts are more than 15 years old.
2.Your home is excessively dusty, or allergies are more severe at home.
