Hi! Freeze ups are caused most of the time by a low refrigerant charge. Before you call someone to check the charge on your system I would make sure the filter is clean. Freeze ups can also be caused by a dirty blower wheel, dragging motor (might need a new capacitor) or a dirty evaporator coil ( might need cleaning on the under side). Most of the time it is low on charge. Yes, you can turn the air conditioner back on, but make sure the larger line is good and cold going back into the outdoor unit. You will need to possibly get under the black insulation and feel the bare copper line. After the unit runs for 10 to 15 minutes the line should feel like a cold coke can right out of the refrigerator. If it doesn’t then you are low on charge and need to get a technician to find the leak and charge it up as quick as possible. It is very hard on the compressor to run without enough refrigerate. Best of luck!
