How often should you add Freon to AC?

Never. You shouldn't have to “add” refrigerant to a central air conditioner because it doesn't “use up” refrigerant. The only reason you would ever need to recharge (that is, add refrigerant to) your A/C is if you have a leak; once the leak is fixed, the problem should be solved.
