A compressor that is wearing out can show up as a clutch that does not engage, noise from the compressor or warm air at the vents. Warm air can also come from low refrigerant or an electrical fault, so with the engine off and cool, look at the belt, the clutch face and the line fittings for oily residue or damage first, and leave pressure testing to a shop.
