You need to do a little homework to get a realistic answer...
Determine A/C restart amperage at high head amps. Go to the manufacturer if necessary but be sure they understand that you want to know how many amps that A/C is going to pull -when restarting under high head conditions-
Secondly. Find the starting, not the run, the starting amperage of your refrigerator.
Addition
High head starting amps of the A/C
+
Starting amps of the refrigerator
___________________________________
Total Amperage
X 120
Equals Volt Amps We're not done quite yet
Multiply the VA figure times 130%
Now you're in the ballpark for what you need in generator max surge watts.
