What is the optimum freon pressure on the low pressure side of the AC?

What is your question?

When we turned the AC to cool this morning, only warm air was blowing. I tried to charge the unit but the pressure on my gauge started climing up to 100. I shut the motor and the freon tank valve and left the connector attached to the low pressure valve. The "dead" pressure stayed at 70 lbs. If this too high I intend to bleed some of the freon, But how much to bleed

Grasping basic air conditioning basics would be the first order of operation. Proper air flow/compressor operation/fan functioning and charge weight (along with relative humidity and air temps) all play a role in how the system will work. You may be a little over your head, as "just filling it up" will not solve your issues.
