Warm air from the vents, a noisy compressor or oily residue on the compressor body can point to a compressor problem, though other faults in the system produce those too. Before replacing it, look over the compressor, hoses and fittings for oily residue or damage with the engine off and cool; a shop can run pressure tests and open the A/C lines.
