The lifespan of ductwork can vary depending on several factors, including the quality of the installation, the materials used, and the level of maintenance. On average, well-maintained ductwork can last anywhere from 15 to 20 years. However, if you notice significant air leaks, increased energy bills, or uneven heating and cooling, it may be time to consider replacing your ductwork. Our experienced technicians at Tru Comfort Heating & Cooling can inspect your ductwork and recommend whether repair or replacement is the best course of action.
