Looking at it from always on call no thanks, I rotate 1/2 week with 15 other techs.

On Call = time and 1/2, double Time, paid from the time I leave my house until I return Home.
Don't enjoy it but It certainly has it's perks. Once you do it a while you get use to it.

I agree with Gocolts however you may want to verify your suction readings with another gauge if you haven't done so. The temps and pressure you indicate are a little strange. I am a summing the...

Great Post

How's rated versus actual amps?
