HVAC & Electrical engineer Consultation is needed

We have built a product that automate the turning off of the AC through the main breaker.

but we had problem that is , some AC's when turn on again from main breaker wont work again unless you press power on button on the AC and some other AC's workers fine.

how to make these AC's works after turning main breaker on.

also if you have solution for automating turning on/off of AC's that works better than our solution (final product in which we can buy not building new solution) will do so.

the one who answer our questions will take the award
