If you live in an older home, your ductwork might not be sufficient for modern high-efficiency HVAC systems. Ducts and their related pieces—seams, seals and joists—begin to fail around 15 years. They hit their maximum life span 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 lose air. Leaks can drive up your utility bills and lead to poor indoor air quality. Cracked ducts can draw in and spread pollen, dust and other impurities.
Your attic, crawl space, garage or other uninsulated space could be where some of your ductwork is located. Moisture can form during periods of high humidity, causing rust to eat through the metal.
5 Signs You Need to Replace Your Ductwork
There are a couple of other hints that can indicate ductwork needs to be replaced:
1.Your ducts are more than 15 years old.
2.Your home is very dusty, or allergies are worse at home.
3.You can’t control the temperature in specific rooms.
4.You can see ducts that are misshapen.
