The ducts have a maximum lifespan of 20 to 25 years. However, at the age of 15, it begins to deteriorate, which significantly reduces the efficiency of the air conditioning system, so the most prudent option is to replace them. If it's been a while since you installed your ductwork, you're probably wondering if you'll ever need to completely replace them or if a simple repair would do you good. In fact, experts recommend replacing ducts 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 indoor air quality. You should replace your home's ducts after 20 years or much sooner. Ducts can be used for up to 20 years, but the effects of deterioration and prolonged use minimize their efficiency around fifteen years. Therefore, you should change the ducts whenever you notice signs of deterioration.
This saves you money on repairs and replacements, as it allows you to enjoy your air conditioning system for its entire expected lifespan.
