Portable Air Conditioner 12000BTU Delonghi Penguino Pac Ex100 Silent. This unit was working perfectly fine, I had it in storage for awhile.I tested it it turns on, the fan works and the other modes but the air conditioner mode isn't cooling. This is probably due to gas being empty or some easy fix. You're more thank welcome to ask me anything.
