Woohoo, found the generator breaker and it was hidden behind a tube but with all the help, finally found it and now my AC works on generator alone!!! Thank you everyone.
Now my next question, about how long can I use the propane generator to power the AC and fridge? Won't need the AC at night probably but will need the propane during the day to keep fridge cold and AC on. It was a 9.8 lb propane tank.
