To ensure that your air ducts remain in good condition and provide high indoor air quality, experts recommend replacing them every 10 years. In some cases, air ducts can start to malfunction even before they reach the end of their useful life. If your ducts are older than 15 years old, it is best to replace them before major problems occur, such as pests, voids, or even collapsed sections of the ducts. This will help you avoid drafts or congested areas and ensure that all parts of your home are comfortable. The ducts are designed to last between 10 and 15 years on average.
They are made from a combination of materials such as fiberglass and plastic. If it's been a while since you installed your ductwork, it is best to replace them every 15 years or so. This is because duct materials deteriorate over time and, when this happens, it has a major impact on the performance of the air conditioning system, which can lead to a reduction in quality of indoor air.
