It has to do with the temperature outdoors. If the temperature outdoors is high, such as it is here in Texas, and you turn the AC unit down to under 65 degrees, or even lower when you first start it up, you will increase the chances of the AC unit freezing up. When you run the AC unit non-stop at a low degree, and set it to "ON" as opposed to on "AUTO" where the unit gets time to rest between cooling, you will freeze it up. Your best bet it to set it at a reasonable setting and then decrease it gradually, and try to keep it on "AUTO" if you are going to keep it on for several hours or for a prolonged time. Good Luck.

You have many answers as to why, now to avoid the problem you need to clean you unit. You can purchase a can of foam coil cleaner. Most will state they do not require rinsing but I would recommend rinsing if at all possible. Follow the directions on the coil cleaner and rinse well even if it is just with a hand held spray bottle of water. Clean your filter and re-install. This will make a huge difference and stop the freezing problem.

As stated before it can be a combination of numerous things. Do not max out your thermostat, clean your coils and filter, but if that doesn't help then you are low on coolant. If this is the case your probably better off to replace it (the other alternative is to pay more to have a HVAC contractor to install a schrader valve and recharge the freon) this usually costs more than a replacement AC.

It may be a little low on charge, as head pressure rises with outside temps it may work fine but when it is cooler outside the head pressure may drop below the freezing point. If this was an everyday occurance cleaning filters would be best answer, as well as cleaning coils, but since it is "Occasional" I'd have the charge checked.

Water + cold = ice.
If it's raining, it may freeze.
A/Cs also tend to make water, depending on what kind you have.
