Maybe the simplest solution would be to try a rudimentary form of step-start relay to crank the A/C compressor. This used to be quite common before the days of VFD's and such.
The regular start relay applies power to the motor via a resistor that limits inrush current to some safe level to start the motor turning. When the motor reaches a certain speed the voltage across the resistor drops enough that a relay down stream of the resistor picks up and shorts out the resistor applying full voltage to the compressor. This method was used in many motor circuits, several broadcast transmitters, and some ham radio amplifiers. Some applications use a timer to energize the second relay. And, of course, there needs to be some precaution paid to deal with a locked rotor.
