When it comes to the life expectancy of a flex duct, industry experts agree that it typically lasts between 10 and 25 years. Most flexible duct manufacturers guarantee their products for around 10 years, while residential ducts can last anywhere from 25 to 70 years, with an average of 45 years. The difference in lifespan is due to the variables of materials, workmanship, and maintenance. Flexible ducts tend to have a shorter lifespan than hard ducts, and they can sink over time and restrict airflow if not properly suspended. Every time you search the Internet for how long a flex duct lasts, you'll likely find that it's estimated to be between 10 and 15 years. To ensure your flex duct lasts as long as possible, it's important to choose the right material for your application.
Flexible ducts are made from a variety of materials, including fiberglass, aluminum, and plastic. Each material has its own advantages and disadvantages, so it's important to consider your needs before making a purchase. Additionally, proper installation is key to ensuring your flex duct lasts as long as possible. Make sure to follow the manufacturer's instructions when installing your flex duct and use the correct tools and materials. Finally, regular maintenance is essential for keeping your flex duct in good condition.
Inspect your flex duct regularly for signs of wear and tear, such as tears or holes in the material. If you notice any damage, replace the flex duct immediately. Additionally, make sure to clean your flex duct regularly to prevent dust buildup and other debris from clogging the system.
