Mechanic Q: A/c not working ?

My air conditioning has not worked for a few months now. Since the weather is getting hot I decided its time to fix it. The compressor was not engaging, so I started with a recharge kit. The r134 was low, but not empty. I charged it to proper pressure, and now the compressor engages, but I still get hot air from the vents. What's next on the troubleshooting check list?
