just charged my a/c
hey everyone...i just finished charging my a/c system today and i got it discharged and vaccumed...but added the charge myself...a book said i need 22 oz. of freon and 4 oz. of oil for my system...i did that and it only took it 25 psi...i used 2 12oz. cans...should i add more? i ask because i was told not to add more than two cans...let me know what you guys think..thanks

I woudn't put any more. If you are not so sure just drive it for a few days and see for yourself how it cools down.
If it isn't working good enough with two cans it means that there is another problem somewhere else. Additional charge of freon won't help you. At certain point additional freon will reduce an A/C performance.
Why did you charge it at a first place? Is it leaking or you disassembled A/C components and put them back?

25 psi at 2000 rpms is good, if it is not cool, check the high side, is it between 200-300? If it is much higher then you have a blockage in your system and I think you actually are an ounce too high on that charge. How long was it vaccumed? a half hour is minimum for a good vaccuum. I suggest 45 minutes. Also if there is alot of dirt in the condenser or the fan doesnt come on it will not blow cold, verify these as they are the easiest to test.

get one of those cans with a gauge.. it will tell you how much to put in... I only bought one can of the big ones (like a 1 liter bottle) and only used half of it...

Here's a newb question. Why do you need to charge the system? Was it just not blowing cold or is part of general maintenence? I was just wondering b/c my gf's old 90 teg's a/c was never charged (from what I know) and it blew pretty cool for a 90.

well it was charged...but it had air and moisture in the system so i had it evacuated...and i just charged it myself...with 2 cans...its cold right now...but on days over 80...it doesnt work too well...
