Is the compressor running 24/7 or just the fan? If the compressor is running all the time and turning it off, waiting a half hour or so for any ice in the evaporator coils to thaw doesn't do it, then you've got something massively wrong in the Freon circulating system that I just can't figure out.

If the compressor is cycling with the hot and cold then I would suspect something with the thermostat circuit. I had something like this once when the thermostat didn't always make contact but then later would, a new thermostat solved that one.
