A saturated head pressure 30°F above outdoor temp, doesn't get you 30°F of subcool. While 8 and 10 SEER A/Cs did often have to run 30° saturation over outdoor temp, you still only had 8 to 12° of subcool. Charge by subcool, or by superheat.The low-side should be near 30 PSI at 90 degrees Fahrenheit or less. Pressure that is too much lower or higher shows there is a problem. On a properly working system, high - side pressure will be about twice the ambient temperature, plus 50 PSI.R22 Refrigerant Pressure Temperature Chart.
