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.
Check your owner's manual or ask your service advisor for service recommendations. And if you're hearing strange sounds when your air conditioning turns on, or if it just isn't as cold as it used to be, have us give it the once over see what it'll take to keep you cool.
