AC Recharge?

So my AC doesn't work very well. I Was hoping to get some advice from all of you. First, when I turn it on my Battery volts drop. Seems to be a little much. Then when I am above 1250 rpm it stops coming out the main vents and just comes out the windshield defrost vents. Works fine at idle and if I keep the rpms low. But I do mostly highway driving and it kills me... I was told my fan belt could be replaced, but not sure if that is it. I haven't really had time to fiddle with it to much. Any thoughts? Low on Free-on? Thanks for all your help...
 
vacuum leak is responsible for HVAC exiting the defrost

loose belt would cause slipping and alternator to charge low, but depending how low, it's normal for slightly lower reading during use.


if it's cold when it's blowing, I doubt the charge is too far off.
