If you live in an older home, your ductwork might not be adequate for today’s high-efficiency HVAC technology. Ducts and their related components—seams, seals and joists—begin to break down around 15 years. They reach their maximum usefulness 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 leak. Leaks can drive up your heating and cooling costs and cause poor indoor air quality. Separated ducts can bring 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. Water buildup can appear during the summer, causing rust to eat through the metal.
5 Signs You Need to Replace Your Ductwork
There are a few 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 bad at home.
3.You can’t control the temperature in certain areas.
4.You can see ducts that are crushed.
5.You smell a strong mold smell when your HVAC system is running.
Having put in new ductwork can make your home more comfortable—and healthier—through improved temperature management and air quality. Plus, it can improve your furnace’s and air conditioner’s efficiency.
