I know that the classical motor in a fridge has a device, I don't know its name, that thermally triggers if the motor demands an unusual high current for some seconds, like when starting under load. It then keeps the motor off for a long time (minutes?), while the compressed gas leaks into the circuit, the pressure drops, and then the motor tries again.
 Surely a modern fridge or AC unit with inverter knows how to cope with the situation.

Most controllers (i.e., thermostats) have built in timers to ensure they
don't call for cooling in a customizable window after their most recent call.
Nowadays, you would also expect the controller *in* the HVAC to implement
some safeguards.
If you actually play with some of these systems, you will note that
the software actually can't be "confused" by things like removing power
during that period; on application of power, they automatically begin
that timeout interval -- as if they had just finished calling for
cooling!
