Even with regular service A/C parts can just wear out. Normal wear and tear eventually gets to all moving parts. Addressing early problems can save on more extensive repairs down the road. For instance, a common failure is the clutch that turns the compressor on and off. If you can take care of a bad A/C clutch when it first starts having problems, you may be able to save the compressor. Wait too long and you'll have to replace both.
