AC Help

I have a 2003 GT that was having issues overheating. Realized that the overheating only occurred if I used the AC for long periods of time so I began to only use it for short drives. It seemed to progress as about a month or two ago I had the AC on and I saw smoke coming from under the hood—seemed to be coming from the AC accumulator but not entirely sure. Does anyone have any advice on how to resolve this issue?
