Question A/C Issues??

Hello to all. I had recently replaced the front heater core on my 99' expy EB, but the problem I seem to have is that I feel that the a/c isn't cooling enough as before. To start off, if I have it at Automatic (70 deg) or Max (60 deg), it seems that it isn't as cold as before. It feels colder when I turn the rear a/c on the "Rear" position and have the rear a/c console on. Could it be that I'm simply low on freon?? Also, I don't know if it is related to this but I can hear a light hiss that comes and goes towards the rear of the truck. I need to pinpoint it where exactly it is coming from, but just to let you know. Anybody had a similar situation to this?? Thanks in advance.

Yeah, put some gauges on it and see if you're low on 134a. Both of my AC lines had to be replaced due to leaks so they're not uncommon.
