a 5500 will work adequately.

The issues in not always on the size but for each the generator needs to be at least 7500 watts with a 30 amp. The issues is make sure you set it up correctly and have a switch back box. The other items that will suck out the pwer is Hair Dryer and Microwave, so make sure you read the btu useage correctly. The load on a generator will only give you about 75% power and most will run on 7 gallons of gas for 5 hours

Generator sizing for large motors,
(like your A.C. compressors), is a bit more
complicated than just adding up the loads.
You must assume that the largest motor will start,
(and momentarily draw about 2x its rated current),
while the others are drawing their full load.
If we assume two motors at 2400W. ea.,
your generator must be rated at least
5000W. constant, 7500W. surge.
(John seems about right with his estimate),
but do check the nameplate ratings on the
units you intend to serve. Take the total
load of both units and add the full load of the
largest compressor.(All this data should be there.
In single phase power, Volts x Amp.s = Watts or
KVA. The numbers you compute may not work
out exactly to those listed due to something called
'power factor` which we won't go into here. )
That will give you the minimum generator
"surge rating". Add any other loads you intend to
serve for the "constant' rating.
Do buy a "Power Rated" unit rather than a cheaper
"Standby Rated" unit, as the cheaper units are not
designed to operate near full load for long periods.
I'd suggest going just a small step larger than your
calculated load. (The generator will be most efficient
near full load, but will last longer at a bit less.)

I have never come across such a small a/c unit. 1,000 BTU is the cooling/heating effect, and if you take into consideration the COP of the system the power required would be very small and no more than 150W. Any size generator would do.

About a 10,000 watt unit should do it for you. 8793 watts full load for the 2 units.
