What Is the Ideal Interval for Servicing Your Car AC

Living in a hot climate has made me realize how important it is to stay consistent with AC servicing, but I have always been unsure about the right timing, so I started looking for a proper guide to auto AC maintenance intervals instead of guessing. Some people say once a year is enough, while others recommend checking it before every summer season to avoid sudden failures. I recently read an article explaining how often you should service your car AC and it highlighted the benefits of regular inspections such as better cooling performance, improved efficiency and preventing expensive component damage. I would really like to know how others here decide on their AC service schedule and whether sticking to a set interval has actually helped you avoid major repair costs.
