My central A/C line going to the unit is frozen

I noticed no air blowing out of my vents with the AC on. I went outside and looked at the unit and it looks like the lines are frozen. I shut the unit off .what could be causing this?

The lines..... or more importantly..... the larger line should be 100% insulated from end to end. If it's icing up..... especially inside at the air handler.... then you are either low on refrigerant or have an airflow problem. Make sure you have good airflow coming out of the registers. Make sure the filter is clean.

Airflow or refrigerant problems will cause it.
Is the blower running?
