Actually if your lines have ice, then check the the fins in the air handler (Where thos elines goto in the house), they probably are covered in ice as well, usually the result of poor airflow and/or high moisture.
If so, turn off the AC, open the access panel to the cooling coils, and let them thaw out, you can use a low heat hair dryer to speed it up some. Just don't pick at it and damage the fins.
Once thawed, spray some 409 on the fins and use a soft bristled brush to brush them clean. Then rinse with sprayed water, let dry, and you should be fine.
Also, check the filter in the air return, it's probably filthy. They need to be changed or cleaned about every 30-60 days depending on how much you use the AC.
