Should I get a AC flush or just a recharge?
I have a 2012 Infiniti g37. In November my dad helped me replace my radiator. In the process he undid the pressurized AC coolant/refrigerant (I believe that is what it is called) it was fine for winter since I didn't need my AC. However it is getting hotter where I live and almost summer. I need to get it fixed. Everything online says to have a mechanic do it so I don't cause further issues. I am just not sure if I need to get both services done or just the recharge. I am completely clueless about cars and would appreciate the help.
