Appreciate it skw, will get my post count up and apply for pro cause i have alot of questions ha ha, my supervisor is just a manager so he really only cares about how much it will cost to repair, and the other maint. tech is as green as i am, so i really dont have anybody else to ask questions! The company i work for "supposedly" has a regional guy that i aam to ask any A/c questions but I have called him about 10 times in the last couple of months and he hasnt returned any calls. Thanks again!

You should really consider taking some classes to further yourself in the field. Do you guys use reclaimers and micron gages?
Ive got a couple of classes coming up this fall, intro to ref. and comfort cooling at local tech school. We have most tools vacuum pump, gauges, micron gauges, recovery machine, recovery cylinders, scales, ox-acytelene torch, a fieldpiece sh/sc meter. Problem is trying to learn on the fly and under pressure without a more expierenced person to ask questions. i have done pretty good by reading as much hvac material as i can find but that cant replace expierence and all the little tips and tricks you cant find in a book.
You either have an air flow issue or a leak that needs to be repaired, assuming an R22 system.
Best thing to do is to get a good evaluation from a reputable company and pay them to fix the problem. Easy as pie. Find a company tha guarantees their work the first time and let them figure it out.

It is amazing that you are able to diagnose that with so little information. Uh hire a company to do your job for you, brilliant why did I not think of that. You need to be careful not to lead a person in the wrong direction, it can be very costly to both the customer and the contractor. Not trying to be mean but try to get all of the info before you take blind stabs at the problem, it is kind of like defrosting a freezer with an ice pick.
From everything i have gathered, I do not think it is a airflow problem. I am going to recover, open and check orifice, install a new filter drier and sight glass which it does not have now, weigh in charge and see what happens. Thanks skw and beenthere, hope to get to pic your brain more when i qualify for pro board!
Thanks guys, compressor was changed in april 08, no problems until last week, lady called office and said she had ice all over filter, another tech checked the first time and said filter was dirty and low charge, he changed filter and charged unit. Lady calls back to the office on thursday of this week and said it was froze again. i checked this time, let unit thaw, turned on cool, hooked gauges up and had 38psi low and 130 psi high, thought to myself we have a leak, walked to shop to get nitrogen etc and other tools, returned to unit about 20 mins later and i had 72 psi low and 250 psi high. Condensor was pulling some major heat out, i cussed to myself a little bit, evap. fan was set to run low speed, I installed black wire from motor to control board to run at high speed you could feel and hear the change in motor when I started back up, cleaned evap. coil and condensor, thought to myself that fan was on low speed was the problem. Turned unit back on, check gauges and it was doing the same thing as before. Been keeping check on unit since friday and it is cooling but just a matter of time before conditions are right to cause it to freeze up again and the lady can yell at me again. Ha Ha
I would replace the evap fan relay..had that happen more than once. It sounds like you are on the right track with the air handler.
