Air conditioning malfunction need HELP

IF the air conditioner quit because of refrigerant and oil leaking, then without knowing where the refrigerant/oil is leaking from it is hard to guess at what issue could be. Air conditioning systems need to operate at specific pressures and there are various components that need to work properly in order to maintain those pressures. It could be that the system pressure was to high and it vented through a safety valve or another possibility is that a seal or hose failed and will need to be replaced. Regardless, it would take a properly equipped shop to recharge the system and check pressures after repairs are performed.
