Hi there, Are those pressure readings in psi?
Customer: replied 2 years ago.
yes they are in psi
Expert:  JayPutelis replied 2 years ago.
With those readings being in psi, this indicates the system charge is low. There should be a label on the underside of the hood indicating the amount of refrigerant the system holds. The system should be evacuated and recharged using a certified ac machine, not just added with cans from a parts store. Let me know how the system was checked. Thanks.
