1. If coil were dirty air flow would be low and the suction line(large copper line) will be extremely cold and ice the entire coil , suction line and compressor.2.Acessing the coil will be a job but I can direct you if we need to check it.3.an you tell for sue compressor is running?3Does small line feel warm and large line 'beer can cold"?

If both lines are room temp even with it running, either compressor is not pumping or we are low on refrigerant.
