We have a Fujitsu ASY-40UIM3
You would have noticed if anything serious had happened, such as puncturing the freon tubing.
So I believe most likely all that is left is that either electrical connections were disconnected and not restored properly, or a component was damaged by g-force shock.
What I suggest is turning the power off and try disconnecting and reconnecting the wires.
Make sure there is no corrosion at the contacts, and use contact silicon on the outside connections.
You should also check that the outside fan is not binding and can turn freely.
Then when you try to operate it, notice if the compressor goes on, if the condenser outside get hot, etc.
Before we can tell what is the problem, we need to know if any and all parts that are working.
As a final suggestion, it is possible components were disconnected and connected while there was still power to the system. If so, then arcing could damage any solid state controller or relays.
If so, then you would have to bring or send them in for diagnosis in the shop.
