Most gas furnaces last 15 to 20 years, and Middle Tennessee’s short, sharp heating season is gentler than in colder states. What pushes a system to the long end is boring and consistent: filter changes, an annual tune-up, and fixing small faults — ignitors, sensors, capacitors — before they cascade. What shortens life is short-cycling, poor airflow, and ignored safety trips. Past 15 years with frequent breakdowns, or any cracked heat exchanger at any age, replacement is the honest conversation, not another repair.
