AC problem ?

[Cinniot]

I used to have a C3 when it was released newly. My father bought me that as a present. 1 year it was working awesome, no serious or heavy problems. But after then, some time ago, the car would heat up every time i tried to use the aircon while the car be on neutral or parking....?? I am planning to buy a Citroen again so is there anything that you could tell me about this problem in any other or C3 ??

What do you mean by heating up? Do you mean warm air coming into the cabin, or the engine temperature increasing?
