Warm air from the vents, a noisy compressor or a clutch that no longer engages can mean the compressor is worn, though a refrigerant leak or another A/C part could be behind any of these. With the engine off, look for oily residue around the compressor and its fittings, or damage to the pulley, and leave pressure testing to a shop before you replace anything.
