You have not said if it is a central unit or a window unit
A window unit can frost up if you are running it on low or med. fan speed when it is very hot outside especially if the hot afternoon sun is beating on it. It can also frost up if it is 20 or more degrees colder outside than inside and it is hot and humid inside and the fan speed is on low or med. If the condenser coils or the evaporator coils are blocked or the filter is blocked it can frost up. Finally if it is low in refrigerant it can frost up.
A central unit can frost up for basically the same reasons except you usually don't have different fan speeds although the filter being blocked is the most likely culprit and the A coils (evaporator coils) is a good second but grass clippings on the condenser coils can cause problems as well. Of course fans not running defiantly will cause this problem. Expantion valves and other controlls on central units can give trouble also.

I'm not an expert in the area, but I know a little.
It can be caused by the temperature of the incoming air from the air intake is not warm enought to keep the coils from freezing.
For instance, if the temp on the coil is 32F and the incoming air is about 50F (just picked this number out of the air), the 50F air would probably not be warm enough to keep the condensation from freezing on the coil.
If a 32F coil had incoming air at 90F, the air would be warm enough to keep the water condensation on the coil from freezing.
Just one possibility

it must be grimy. attempt to take it out and sparkling it with a backyard hose. when I say "it" I recommend the condensing unit, the aluminum fins. be sure you concentration on the contained in the coil the position the fan is, it is the position the airborne dirt and dirt/debris is as a rule positioned. the different determination if the unit isn't grimy is, the equipment is low on refrigerant. some HVAC techs will placed a service port on room ACs to recharge them.

Your unit needs service. The condenser is about to go or has already blown. Call an HVAC technician.

Airflow problem i.e. stopped up filter, failing blower motor. Stuck contactor inside condensing unit. Or low on freon from system leak.

If it is a central unit, it would be a good time to call your local pro. Probably cost $100 for service call.
The one thing that you can check yourself is the filters.

Believe it or not, usually, a sign that your unit is low on freon.

try freon ...also extremly hot days will cause a a.c. to work extra hard and form ice to keep compressor cool

YOU HAVE A LOW VOLUME OF HIGH-PRESSURE ON YOUR REFRIGERANT LINE WHICH ICES YOUR LOW-PRESSURE COILS--YOU HAVE A MAJOR LEAK! LOOK FOR DARK OIL ON YOUR LINES WHICH INDICACATE A LEAK! GET A MAINTENCE/HVAS \REPAIRMAN TO RE-SOLDER LINE AND REPLACE LOST COOLANT--IT WILL BE EXPENSIVE! BUT CHEAPER THAN REPLACING IT ALL!

That`s condensation and you might have the freon serviced.
