Air con puts a serious strain on ya engine when it's running and generates a lot of heat in the front rad. Make sure that the aircon fans are running when the air con is on.
 
If the air con fans are working you could have a blocked radiator. Feel the radiator when its hot, and it should be the same temperature all over, ie no cold spots
 
I have a dico too, and i ditched the aircon!
