So to sum up. I'll turn on the AC and I hear the compressor turn on. The skinny line gets cold and the air inside never gets cold even though I hear the compressor running. I then hear the compressor kind of sputter and I can feel the unit slightly vibrate at this point if I'm touching it. Right after this the compressor stops and the fan keeps going. From researching it could be that the compressor is falling apart or that it's overheating because something is clogged. If it is overheating would the fan turn off also?
