Need help with my first A/C job

[Jorge89]

I have a 1994 honda civic ex with a 1.6 engine. The A/C compressor it came with had a huge hole so I replaced it. I vacuumed the empty system for about half an hour and then closed the gauges in the manifold and waited for another 30 minutes to make sure there was no leaks in the system. I can see under the hood that I need to put 17.6 to 19.4 oz of refrigerant under my hood so I got a 14 oz can and a 3 oz can ( the only other size I could find was 22oz and I have no way to measure how much I'm putting int so I think it would be best to be slightly lower than overcharging by a lot). I filled my system through the low side and the gauges show 95psi on the low side and 100psi on the high side. I'm not sure but I think my low side might be a little high. The air from the vents is still coming out hot and when I try to unhook the low side I get a leak so I've had to leave the hose on for now.

This is my first time doing this and I don't know what could be the problem here. I would really appreciate someone's help on this. Thank you in advance.
