I doubt that size will power the central AC, IMHO, get in the hose, get several months of actual electrical use, then investigate the need for a generator and the appropriate size.
Now having lived just North of 44 for 6 years, there have been very few power outages, and NONE in this area during Irma. The outages we have had were generally less than 2 hours. While I have thought about getting one (had on up north for a 5 day outage), but really does not seem to be justified here, at least not for a whole house unit ($$$$$), a small inverter based unit ( 1 to 2 kW) would cover the refrigerator, small medical devices, a few lights, and a fan or 2.
