forget about the gauges. They told me that I need to totally evacuate the system and refill it for some reason. I just want to know if that is correct of if it's overkill. If I need to do it to prevent a problem I will. the only thing funny I've noticed since I fixed it is that the compressor engages after you start the engine and never disengages
Automotive AC systems are filled by weight.
You have no idea how much you have in it and neither do they so yes they would have to completely evac the system,pull a vacuum,and refill by the required weight.
That is about $100-$150 depending on how much R134A needs to be added.
