No Cold Air - Liquid line is ice cold

I am unfamiliar with AC units, however my central AC recently stopped blowing cold air. The fan outside turns on and I've noticed that the smaller liquid line coming inside gets cold, but the larger suction line stays room temp.

I'm hoping its something I can handle myself. Any help would be great, Thanks.

How far in is the small coper line cold from the outside??

A/C system works the other way around as you saying.. The small liquid line flow is from outdoor unit to the coil inside, and larger line is vaper/gas going back to the compressor.

The small copper line is cold its entire length. From what I know of AC units, freon gets cold as it evaporates. Could it be there's too little pressure in the line?

yes, Sounds like you may be low on charge, or something is cutting down on the flow from the outdoor unit.

don't run the A/C any more till you get service.. Don't want you to burn out the compressor.
