I get this quite regularly on air conditioning systems that I service. Normally they just short out the mains and take a fuse, cap or pcb track out, all of which or easy to be repaired, unfortunately the lizards can´t be repaired.
I did have an incident last year where a lizard stepped across the mains filter cap, the fuse and main processor on the pcb. There was nothing left of the lizard at all, other than a skeleton, the cpu was fried as well as a few miscellaneous components. The fuse was alright though. All in it cost around 2.000€ worth of damage.
They seem to prefer inverter systems for some reason.
