Generally speaking, you want around 27-psi on the low side and 200 on the high side. Why 27-psi on the low side? Because, on an R-134a AC system, 27-psi. on your gauge means the refrigerant will produce about 32ยฐF at the evaporator (as long as the orifice tube/expansion valve is operating properly and there's no air in the system that's artificially inflating the pressure to 27-psi).

The lower high side pressure may be from an undercharged system and the TXV is keeping the low side at 30 PSI. The old systems used a sight glass to charge the systems. Find the sight glass and observe the refrigerant flow while the system is running. If the sight glass is clear liquid the system is fully charged.
