As an HVAC expert with years of experience, I have seen firsthand the impact that aging ductwork can have on a home's heating and cooling system. Many homeowners are unaware that their ducts have a maximum lifespan of 20 to 25 years, and at around 15 years old, they begin to deteriorate. This deterioration can significantly reduce the efficiency of the HVAC system, leading to higher energy bills and poor indoor air quality. So, should you replace your ductwork after 20 years? The short answer is yes.
While it may seem like a significant expense, replacing your ducts is the most prudent option in the long run. In fact, experts recommend replacing ducts approximately every 15 years to ensure optimal performance and efficiency. The reason for this recommended timeline is that duct materials naturally deteriorate over time. This deterioration can lead to leaks, cracks, and other damage that can greatly affect the performance of your air conditioning system.
Not only does this result in higher energy bills, but it can also compromise the quality of your indoor air. As such, it's essential to replace your ducts after 20 years or even sooner if you notice signs of deterioration. By replacing your ductwork at the recommended intervals, you can save money on repairs and replacements in the long run. While it may seem like an added expense, it allows you to enjoy your HVAC system for its entire expected lifespan without any major issues.
