Hello, my name is ***** ***** I am a professional here at Just Answer. I have noticed that your question was not getting a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.
The low side service port is the one on the accumulator so you found the correct port. In order for the AC to cool properly you need a full system. Normal operating pressure on a full system should be right at 30 to 35 PSI on the low side and right at 200 to 225 PSI on the high side. If you can give me your actual pressure reading I can help you get this resolved. Post back when you can and we can work from there.
