So you are able to plug into that outlet BUT you'll only have 15 amps available and that will not run a/c.
You only have 30 amps at 240 volt sorry.
The genny does not decide weather 120 or 240 is put out. Its what we plug into it. If you plug a twist lock into that plug with only one of the hots tied to it it is 120 if you plug a twistlock into it, with both hots tied to it, its 240.
An assumption was made here as well. Most smaller gennys with a 120/240 plug are 20amp twistlocks not 30amp. His genny is a 4000 watt set max amps is 33.3@ 120 or 16.6@240
