The answer to 'how long will AC last' is that a well-maintained air conditioning unit can typically last 10-15 years, with proper care and regular maintenance. The lifespan of an AC system depends on several factors, including the quality of the equipment, how often it's used, and how well it's maintained.
Proper maintenance, such as annual tune-ups, filter changes, and cleaning, can help extend the life of your AC unit. Additionally, factors like the climate in your area, the size of your home, and how often you use the system can all impact its longevity. If you take good care of your AC and address any issues promptly, you can expect it to provide reliable cooling for many years.
