After driving for about an hour the A/C stops blowing air out of the vents?

A/C works fine until you've been driving for about an hour nonstop. At this point it seems like the vents are all blocked. You can hear the A/C blowing full blast, but nothing comes out the vents.

Thanks, Lori

This happens when the system is just a little low on refrigerant, it causes the evaporator to ice up due to the excessively low pressure. Here is a video that can help you add a little to your car:
