roman,
If your system can blow "very cold air" under ANY circumstances whatsoever, it is exceedingly unlikely that you need to add any refrigerant. Likewise, it is exceedingly unlikely that you have a leak of any kind after all this time. Sounds to me like the low pressure switch is bad. It doesn't take much gas to close it. A car can have insufficient gas for cooling and STILL close the low pressure switch and run the compressor. Unfortunately you have to discharge the system to replace it. As long as you know it's cooling, one could consider bypassing that switch. The risk is not noticing that the charge has been lost and having the system run with no gas in it - - would ruin the compressor fairly quickly.
