Is a Micron Gauge used during evacuation?
Was 1000 microns or less reached during evacuation?
Do evaporator blower speeds react to low, medium and high-speed settings?
Turning thermostat counterclockwise and then clockwise, does compressor turn
off and then on? If a dual system, verify thermostat and pressure switch wiring is connected

If dual system, is each system checked separately (independently of each other)?
Is freeze-up thermostat (located in evaporator) properly adjusted? Turn
