As a seasoned expert in the HVAC industry, I have witnessed the detrimental effects of aging and deteriorating ductwork on a home's air quality and overall performance. Many homeowners are unaware of the recommended lifespan of ducts, which is typically 10 to 15 years. However, after this time, issues can arise that significantly impact the efficiency and effectiveness of the air conditioning system. That's why it's crucial to prioritize replacing your ducts before major problems occur. One of the primary reasons for replacing ductwork is due to natural deterioration over time.
This can be caused by a variety of factors, including age, wear and tear, and even pest infestations. As ducts deteriorate, they can develop voids or even collapse in certain sections. Not only does this affect the performance of the HVAC system, but it can also lead to poor indoor air quality. While regular cleaning and repairs can help prolong the lifespan of ducts, it's highly recommended to have them replaced every 15 years to ensure they are functioning correctly. This may seem like a relatively short lifespan, but it's essential to remember that ducts are constantly exposed to air and other elements, making them more susceptible to wear and tear.
