generally, a freon leak causes freezing....it's all based on the Ideal Gas Laws. If there is a freon leak after the compressor, the gas will decompresswhen it gets outside. Since as a gas decompresses, it increases volume and decreases temperature, it will cause moisture in the air to freeze to the unit.

Dirty coil that you can clean yourself (outside and inside coils) could be the culprit. Also could be low on freon, that requires a license to fix but if you know someone with gauges for A/C you can check it yourself, the pressures for the high/red and low/blue side can be checked against your unit info.
First I'd try cleaning the coils. Easiest for most homeowners to do. On the outdoor coil, the thing the fan sits on, rinse it with water from the inside to the out...disconnect the unit first, remove the fan to a position where you can get to the inside. Don't worry, you can't hurt any motor parts or electrical from there...it's made for outside. there are cleaners you can buy but make sure you are at an A/C place and you read the label!! The indoor coil (if you have one) can be cleaned roughly the same way. Use a spray bottle and a soft toothbrush if its really dirty, careful you don't bend any of the fins. Stuff for cleaning them is also available and will last and the great thing about it is that you just spray and go. the use of the A/C itself will take care of cleaning after that.

Usually not enough air flow through the evaporator would cause freezing up. This could be a defective motor, a dirty evaporator coil, or restrictions in the duct system such as closed registers, or closed air dampers. Make sure the return air registers are not blocked by furniture also. I have also seen papers or pet hair get sucked into the blower wheel and reduce the airflow. There usually are several speeds that the motor can be operated, you may need to increase the speed.

about 1 month ago I had the same problem. When the Technician came out my freon levels were about a 1/2 pound off. He said that was not enough to make it freeze up. He fully filled up the unit with freon and tested for any leaks. He found a leak in the hose from the ac to the house. He put grey sealant in the part were you screw it on and it was fixed.

Your system is low on freon. You need to have the freon charge corrected right away. If you continue to run the system under these conditions, you could damage the compressor and the repair bill will be much higher.

It is dirty or low on refrigerant. Turn system off. Use garden hose on medium or low pressure to deice outside unit and clean coils. Try not to get wires, motor, etc. too wet. If it freezes again a service tech. will need to charge the system.

Fluctiations in electricity can also cause central a/cs to freeze up. But I also think if you have a freon leak in your coils that it can also make it worse.

Check the freon level.

It might b a bad compresser, or it may need freon

Get a repair person and turn the temperature up, you're over airconditioning
