How to know if you need a car A/C?
A clicking sound. The indication that you’re in need of car A/C repair is when you hear the compressor making a clicking sound. With less gas to compress, the compressor begins short cycling, much like we would gasp for air if we were at high altitude. This makes a clicking sound that serves as the earliest warning system of a leak in the A/C system. There are several causes of short cycling, but low refrigerant is the most common. Again, this is an early warning sign and immediate attention is required.
