Consistent hissing noise from a/c, a/c pushes low air pressure
 

I was driving along and the a/c on my 2008 Honda Accord went from full speed to little to no air with not that cold of air. It would also be accompanied with a constant hissing sound from the vents. Does anyone have any idea about what the cause of this may be, or, better yet how to fix it? Thank you

Make a visual inspection of your A/C condenser (behind the bumper) to see if a rock damaged it.
