You are low on refrigerant or your air flow is obstructed. A service tech will have to diagnose your refrigerant levels, but you can do some trouble-shooting to rule out air flow problems:
Is your a/c filter loaded or clogged?
Is your evaporator coil plugged with mold and/or debris?
(if you can't get under your air handler to look up at the coil, the service tech will have to make this call as well)
Are any of the supply lines collapsed in the attic, especially a trunk line?
Do you have a remote or overhead return air duct that is collapsed or obstructed?
Has a piece of duct board or debris been sucked under your coil
and is blocking air flow?
There is also the possibility of a malfunctioning metering device in the air handler. In any case, I believe you will benefit from a careful diagnosis at the hands of a qualified service tech.
Good luck!

Check your filter and change if dirty. Check the temp of air into filter and air out the vents. If the temp difference is less than 16 degrees, you are low on refrigerant, if it is more than 20 degrees, you have an airflow problem. Please do the checks with the ice melted. Running the unit while it is iced up can kill your compressor.
If the temp difference is above 20 degrees, you probably have a dirty coil i.e airflow problem.
Info based on the assumption that the inside unit is icing up and Tstat set to cool

change air filter, increase air to a-coil.
