The answer to 'lifespan of AC' is that the typical lifespan of a central air conditioning system is 15-20 years with proper maintenance. However, the actual lifespan can vary depending on factors like the quality of the equipment, how often it's used, and the climate conditions where the home is located.
Well-maintained air conditioners in moderate climates may last closer to 20 years, while units in extreme heat or heavy use environments may only last 10-15 years. Proper annual maintenance like changing filters, cleaning coils, and checking refrigerant levels can help extend the AC's life. Replacing an older, less efficient system with a newer high-efficiency model can also improve its longevity.
