it's the start locked rotor amps that kills most generators. they can't deliver 45 amps or so for startup long enough to get the motor rotating. IF you can get it to start, it likely will keep it running.
Now some air conditions are better than others at starting, but they all suffer the same issue with a conventional cap start induction motor, high inrush current demands and high current until rpm is up enough that the back emf reduces running current.
Now if the switched to the electronic motor controls and high frequency motors used in many house appliances, would be a much easier job.
and just because it starts it at sea level on an 80 degree day doesn't indicate if it will start at 95 degrees, or at high altitude, or both.
