All air conditioners are a closed loop sealed system and should never need refrigerant (brand name Freon) added. If they develop a leak then the leak needs to be repaired first before more refrigerant is added.
The law prohibits adding refrigerant to a known leaking system so most reputable repair personal won't just add refrigerant without finding the leak and repairing it first.
Now having said all that, it is cheaper and more practical to top off a slow leak versus repairing it and some repair people will take pity on you and just top it off if it's a little low.
