Beachboy,
Just as a note, I was roundly dressed down during my time as an Electrical Apprentice for installing an Air Conditioning unit on an RCD (same as a GFCI), even though the thing was a temporary supply with a socket-outlet on the outside of the house, I was told that it shouldn't have been fed via an RCD.
Word came back that the RCD kept tripping because of the compressor leakage currents.
Some electrician's have been caught red-faced with wiring houses here where the fridge or a freezer have been plugged into an RCD-protected outlet, but with the thing tripping months later (home-owners never test them either which doesn't help), usually when the home-owner is away getting some sun overseas during the Winter here.
My advice would be, stay well away from GFCI circuits and Refrigeration/Aircon circuits, as far as mixing the two go.
It will only end in tears.
Refrigeration and A/C manufacturers were supposed to have all of their leakage currents down under the level that would trip an RCD/GFCI, Yay, great to see they took that seriously!.
Once again it is the Electrician that bears the blame.
