Check as stated above the A/C clutch followed by the serpentine belt tensioner and idlers.

Okay I know what the serpentine belt are but what are tensioner and idlers

Tensioner is a spring loaded belt pulley that keeps tension on the belt. Idler is a belt pulley that the belt runs on. You should have someone look at it for you.
