A worn or failing compressor can show up as warm air from the vents, a noisy compressor or a clutch that does not engage. Before you replace the compressor, rule out low refrigerant, a leak elsewhere in the system and a blown fuse or relay for the clutch, since each of those can also leave you with warm air.
