A/C recharge specs.
Hi guys. I've spent about an hour looking through posts for my answers. No luck really, many links are now disconnected.
QUESTION: What are the gauge readings supposed to be, high/low on the AC system?
A/C has lost some cooling ability and I want to see what'* up. I did find these low readings but not the high side.
Temp 80F, Humidity greater than 40% Low side should then be 29-37 psi
Temp 90F, Humidity less than 40% Low side should then be 34-42 psi
Temp 90F, Humidity greater than 40% Low side should then be 37-45 psi
Thanks in advance.
Jim

Those readings seem about right.
Check your condensor fins and straighten any that may be bent. Other items would require opening the system.

Thank you.
Condensor is pristine, I'm going to check the A/C fan @ the radiator and put gauges on it. What I needed was the recommended readings, high & low for 90 degrees with 40% humidity. I was unable to find high side readings in my thread search.
