Use R134 refrigerant, you can buy the kit at auto parts store. If you have a significant leak then recharging will not hold for too long. You could try and see if that solves your problem. It will cost about $20 for the kit. Follow the instruction and inject to the low port side (L) and don't go over the recommended pressure. There is a label inside the engine compartment that says how much refrigerant our cars hold.

In my case, my car has a tiny leak and I have to recharge with 1 can of refrigerant every 2 years or so. That works good for me.
