AC not blowing cold air

Hello,
Want to know if AC compressor is hurt. It was working and blowing not that kind of cold air, but still not hot (although compressor looked to be working continuously without hearing its clutch clicking).

I charged the AC today for the first time in eight years (l do not use that car much, it only made 30,000 km while most of my trips are short city ones). The difference now between before and after charging is huge. I do not recall it was ever that good even when the car was brand new. Does this mean that compressor was not hurt during those years of low refrigerant? Thanks.
