ok,after reading your postings here is what u need to do:
go to a shop that can install a REAL set of gauges on ur system. it will have a hi side and a low side pressure gauge readings. ONLY THEN can u get any valuable info so that there can be feedback to what may/may not be wrong (if anything) with ur system. Most shops charge ~$30 to "diagnose" a system. OR, go buy urself a set of gauges ~$50-$60 and make sure they have the 134a fittings (if you had it converted to 134a).
Using a "kit" that comes with ONE pressure gauge and a bottle of juice aint gonna cut the mustard with a novice owner, this is only a quick $$ making skeme for the supplier. You MUST know both pressure readings to make a complete diagnosis.
Once you get those readings, send me an email and I'll try to help you.
I am not an expert, but have been in the a/c business for 20+ years.

mikejpss is abolutely right.
Here is a simple method you can use to get your charge correct, but you must have an IR gun or a pyrometer to measure the temps.
Set up car with hood open, fan blowing under front of car onto condenser, fan set to high, a/c set to max, doors open, engine at 1500 to 1800 rpm.
Adjust your refrigerant charge (add or remove) VERY SLOWY to get the inlet and outlet temperature of the evaporator tubes as close to the same (32°) as possible, Ideal is within a degree or two. You must let the system stabilize for around 10 to 15 minutes after adjusting the charge. Depending on the efficiency and condition of the system you may or may not reach that temperature, but when they are the same, it will be charged correctly. If need be, trickle water over the condenser.
If this method doesn't get cold air at the vents, you have other issues beyond the refrigerant charge, such as obstructions for the evaporator or blend doors not co-operating.

You cannot properly diagnose or work on a/c systems without gauges. The "suicide kits" are worthless. You have no idea what is going on with the system.
