I now had 20 lbs suction pressure and a not so cold suction line I also had no more Duracool so I just completed the charge with 134 out of my 30 lb jug to bring the suction to 25-30 lbs and a cold suction. I don't expect any problems and it's been awhile. I know some of you will say 20 lbs is where it should be but not in this case if the suction pressure at 20 lbs is not cold and sweaty you are under charged.

If you did not get all the Freon (R12 or R134a) out before you installed the Duracool you will have higher pressures with not enough cooling. If you had evacuated it then 20 psi for Duracool should work just fine.
