COOLING AIR COMING LESS AFTER 1+ HOUR CONTINUES USE OF AIRCON.

2006 Chevrolet Optra • 60,000 miles

Cooling air coming less after 1+ hour continues use of aircon. Was trying to change the cabin filter - but found it is hard to change as it is from down, found ice formation in cooling coil near the filter - it may be the reason of reduced airflow. What could be the reason for ice formation? Thermostat? Blower fan speed?
