Icing can be caused by a number of issues:

1.Low refrigerant charge

2. Dirty ac filter

3.Indoor blowier not moving enough air acrsoss indoor coil

4.Contactors burned together in outdoor unit causing outdoor to keep running after indoor blower stops.

5.Blocked return or ductwork causing restricted air flow

6.Dity indoor coil

Give me as much information as you can about what is happening and if any of above are noticeable and we will go from here.
