Check and see if you have an electric fan, for your radiator. You may have two if I am correct, one is to help pull air through the condenser for your ac, if it is not working your condenser is not efficient; especially when idling because no air is flowing through it ( ex. while at stop light) and causing high pressure on your AC system, thus poor cooling. Electric motor on fan may not be working.

Have this checked first! If you have the AC compressor changed and it still does it, now you have to fix this, double the money.

If it is not this then proceed with having AC system checked.

Hope this helps
