Okay, if the compressor is kicking on then it is probably low on charge.
You can go to any parts store and buy a can with a gauge on it and add gas yourself.
Make sure you read the can and the gauge so you don't over charge it.
If you put a can on it and the gauge says its full IE in the green range then we have another issue.
Here is a guide on how to add gas:

Let me know how it turns out.
