First of all 2200 + 2000 = 4200 (not 4400). Secondly at that altitude you are losing a lot of power; however, the AC should still run. Also, is that running watts or starting watts? Running watts could be way less and make a difference depending on other loads sucking power away at the same time as you trying to start the AC. Make sure everything else is turned off before you start the AC. Lastly, the start capacitor in the AC could be going bad.
4200 isn't running wattage, it is only peak wattage. I believe the 2000 is 1800 running and 2200 is 2000, so you're down to 3800, and at a mile high, it could be significantly lower.
You might need to look into changing jets out in the carb, I seem to recall my BIL had to swap jets when his Honda wouldn't even start/run at high(er) elevation.
a single 2200 is capable of starting and running a dometic or coleman 13.5K AC unit at 7000ft if an easy start is installed. That is with the factory low altitude jet. my brother and I have both done this many times this last summer and this summer with the honda 2200. the honda 2000 will start the AC but only consistently run it at altitudes less than about 4500 ft.
