Keep in mind that the largest A/C that will comfortably run on a Honda EU2000i from our experience is an 8.5K BTU unit. Some people have said that a 9.2K BTU will also run but I have no knowledge here. Many people then also install a “soft start” on the larger A/C units that do enable the smaller gennies to run the larger units.
We traveled Utah in July one year with daytime temps at 118 degrees. The entire town of Moab had a major “black out” so only those with generators were comfortable. I might add that most A/C units have an efficiency limit and can only reduce temperatures by a specific amount no matter how long you run them. With temps at 118, our 14.5K BTU unit on our travel trailer at the time could not get the cabin temperature below 88 which still seemed uncomfortable for us.
