The answer to 'how long will AC last' is that a well-maintained central air conditioning system typically lasts 12-15 years on average. However, the lifespan can vary depending on factors like the quality of the equipment, climate, usage, and maintenance. With proper care and regular tune-ups, some AC units can even last up to 20 years.
The key to extending the life of your AC is to have it serviced by a professional HVAC technician once or twice a year. This ensures the system is running efficiently and helps identify any potential issues before they become major problems. Neglecting maintenance is one of the primary reasons air conditioners fail prematurely.
