By law, this operation must be performed by an ASE certified tech in an EPA certified shop, which will have the necessary equipment to recover, store, and recycle refrigerant, and prevent it from being released into the atmosphere. Additionally, as this operation will open up the air conditioning system, the receiver-drier (if it's a Thermal Expansion Valve system) or accumulator (if it's a Fixed Orifice Tube system) will also need to be replaced.
