If you live in an older home, your ductwork might not be sufficient for today’s high-efficiency HVAC systems. Ducts and their related parts—seams, seals and joists—begin to break down around 15 years. They hit 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 break apart and lose air. Leaks can hike your heating and cooling costs and cause poor indoor air quality. Separated ducts can bring in and diffuse 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 high temperatures, 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 extremely dusty, or allergies are more severe at home.
3.You can’t regulate the temperature in certain areas.
4.You can see ducts that are kinked.
5.You smell a strong musty odor when your HVAC unit is running.
