You need a set of gauges to monitor the pressures. Feeling the lines is no indication of much.
It could be a bad compressor, bad dryer or a bad expansion valve. First thing you need to do is see about the freon. There is no visible way or gauge check to indicate freon level. We remove it and see how much was recovered, then we determine how much is required and move forward. It is a process done by someone familiar with ac systems. I dont think there is much you can do without equipment.
