I have done this before and the A/C works great, don't worry about it not being powerful enough. It's so cold you will be running with it on the lowest fan speed all the time once the cabin has cooled down. Others will tell you to replace a bunch of O-rings and such, and if you really want to do it 'right' you should, but I have found that it's more cost effective just to recharge every other year. At least until I do a total system replacement.... the way it is right now at least gets me thru the summers. I think it cost me about $90 to do it each time.
