First you need to find out if the system is a 134a system or not. It is then it recharged through the low port using one of those recharge kits from Walmart or Autozone or wherever. The port only fits on one side. If it is not a 134a system then you will have to have the expensive older freon put in or get a retrofit kit. The later is cheaper. Then refill with 134a. If system has been opened up then the system will have to be hooked to a vacuum pump and then filled with the proper amount of refrigerant and oil. Hope this helps.
