The first thing you need to do is break out your multimeter and check the system voltage. (No multimeter? GET ONE!) Check the voltage with the engine off, engine running with no AC, then with the AC running at each available fan speed. Those readings will give you an idea if the charging system is working at all, and if it is adequate to handle your air conditioner. If the battery voltage drops below about 14 volts with the engine running, the alternator isn't getting the job done. It could be you need a bigger alternator, or it may be you just need to fix something, such as a slipping fan belt.
You might have a blown diode in the alternator. If that's the case the alternator will appear to be charging when there's no heavy electrical load, but the voltage will drop under heavy load.
