Unless you are certified you will not be able to charge unit up yourself or even attach the gauges. If you are certified, you already know what the pressures should be

Excellent answer!!

Mullins... your question has been answered accurately, but without an explanation. Because of the implied affect that CFC's have on the ozone layer, zealots have forced legislation regarding the handling of freon. Unfortunately in all the years that the laws have been in place, there is absolutely no research, finding, or proof that freon regulation has affected the ozone layer. It was typical of the liberal agenda, to pass "feel good" laws which in effect did absolutely nothing except to raise costs for everyone. So as a home owner, once again you have been assaulted in your wallet.

Needs to be charged by subcooling or superheat
