Two EU2000I's will grunt a bit in Eco mode starting up a 13.5k A/C unit, and bark a little loud, but once up and running, both of them paired will just putt along at 3000 rpm's under very little load, since the load is split among the two generators.
I prefer to just have both generators in regular mode and warmed up to start the A/C unit, then once the A/C unit is running, I turn the inside temp down pretty cold, and then switch both generators to run quietly in Eco mode. It will be a long time before the AC unit shuts off and cycles back on again. And both generators will be running quietly for quite some time at 3000 rpm in Eco mode.
Seems hard to believe, but has to be heard and seen before one gets converted to the idea of it. I'm a believer.
BTW, crappy 10% ethanol gas will really put the hurt on the load capabilities of these generators. I am not making this up, it is very much for real. Cut fuel will cut your capacity near full load on these motors and generators. Get good fuel if you can, and make it easier on the motors to do their job and make the power necessary to pull the load.
