Should last the life of the unit, and beyond. Refrigerant is not destroyed or consumed during operation, the only way it can be lost is by leaking out. The cooling system of an electric house window unit is intended to be permanently airtight and leak-free by the use of brazes and welds at all joints-- a so-called "hermetic" system. Failures that cause a leak are rare and usually dealt with by replacing the whole unit rather than repair.

If it works once, stops, and then works again sometimes, there must be enough refrigerant. There isn't anyone taking it out and putting it back in when you aren't looking. Usually it is a control problem and the compressor is not always starting. Does it make the same noise like when it is working, when it is not working?

This forum is about the A/C systems in cars and trucks, which are completely different and are prone to leak often.
