A/C PSI WHAT SHOULD IT BE?

[astrogus]

1997 ASTRO WITH REAR A/C I LET IT RUN FOR ABOUT 20 MINS WITH BOTH FRONT AND REAR A/C ON AND IT WAS AT 45 PSI....JUST CURIOUS WHAT IT SHOULD BE AT. THANKS

Was 45 psi on the low side service port or the high side service port? Also do you remember what the ambient temperature was?

It was 45psi on the lowside and rougly 89 degress outside.
