Hi people. Well men i have here to many fristration with the refill. I left the car in a ac repair shop and the issue was my air its cold but the system didnt reach the numbers of temperature for do the cycle. This car touch the 35degrees for do it. So. Before when my ac was so badly i refill my self using a only single gauge and i do it with the outside temp and i always left the car like 35psi in the system and wirks excellent. So i told that to the guy and he told me that no work like that. And refill my car using the lable has the car. So its like i didnt do anything because my car yes its cold but its cold when its runing and when its in idle didnt drop the temp for the system do the cycle. I need to know if here in my country every day in summer hit like 90 my car using that freaking label its on 30psi. Its ok or need refill ?
