can a vacuum be pulled on the A/C system and then charged later or does recharging the system have to be done immediately after?
If the low pressure line is subjected to physical blockage right before it enters the TXV, can the blocked line be discovered when a vacuum is pulled on the system?
I have overhauled the entire HVAC system (new compressor, condenser, lines, evaporator core and heater core). I added a total of 5 fl oz of pag oil per instruction (1.5 evaporator, 2.5 compressor and 1.0 to condenser). After the vacuum is pulled, will the oil need be replaced or does the vacuum not affect the oil?
have the same problem?
