The answer to 'how long will central air last' is that a well-maintained central air conditioning system can typically last 15-20 years with proper care and regular maintenance. The lifespan of a central air conditioner depends on several factors, including the quality of the equipment, the climate it operates in, and how often it is used.
Proper maintenance, such as changing air filters, cleaning the condenser coils, and scheduling annual tune-ups, can help extend the life of a central air system. In general, homeowners can expect to replace their central air conditioner every 15-20 years, although some units may last longer with excellent care. It's important to monitor the system's performance and address any issues promptly to ensure it continues to operate efficiently and effectively.
