I replaced my evaporator core and condenser last night and pulled a vacuum on the system for an hour then monitored it for an hour and it held fine.
I left the A/C gauges attached overnight and, about 9 hours later, am showing a slight drop in system pressure.
Last night / this am readings:
I’m hoping to button things back up today but am unsure if this is abnormal (ie: A/C gauges naturally lose some pressure via schrader valves, etc.). In hindsight, I should have removed the gauges and rechecked pressure again this am.
Thoughts on this? I cringe at the thought of replacing the evap and condenser again, but would rather do it now if this system is compromised. Thanks in advance
