AC adds a lot of stress on your cars cooling system. I'd suspect your cooling system is sufficient to cool your car, until it needs to dissipate the extra heat from the AC. Faulty thermostat, faulty radiator fan, clogged radiator fins, bad coolant, or a faulty water pump could be some things to look into.
