I just got my ac fixed yesterday, already it isnt working. It was amking a noise when i shut it off. and now its dead. I already had this problem b4, and i think they recharged it to fix it. like i said when i turned it off, it would make a noise that would slowly go away. now i dont even hear the ac come on at all, and the air is not cold. any suggestions to what the problem is?
