Weak cooling at the vents, a noisy compressor or a clutch that does not engage can mean the compressor is wearing out. Before you replace the compressor, rule out a refrigerant leak and a fault in the clutch wiring, fuse or relay, because each of those symptoms has more than one possible source; a shop can test the system.
