Appliance Repair Questions? Ask a Technician for Answers ASAP
Hi and thank you for using Just Answer
Per your question, the freon gas has leaked out and the warmth you feel is the heat from the compressor.
As for repairing, I don't know if they can. These portable units are set up in such away that you would have to buy a complete internal replacement unit, and for the price you would not be to far off from getting a new one. If you have any other questions please ask. I wish you the best
