The efficiency of the system may decline over time, even if it still operates, leading to higher energy bills. If your HVAC system is approaching the 15-year mark and frequently requires repairs, it may be time to consider replacement. Proper installation and routine care can help maximize the lifespan and performance of your HVAC system, ensuring comfort for years to come.
