The 2400iS runs my 15K A/C just fine at 95*F+ and 600' in elevation. It also runs the converter at the same time, but not much else. I can live with that and am tickled pink with it.
I own a yamaha 2400, it just does the job. I have to manage my devices carefully or it trips the breaker on the genny. honda 3000 would make the device management unnessary, but costs more and weighs more. they are both great gennys, I would say if your able get the 3000.

I will update my experience for others who are in the market.
Here is a final note on why I went with Yamaha.:
Of the 3 outlets I went to, all said they did not get any reported problems or returns. The only problem that users have had, is when they run the oil too low and the user does not know why the unit shuts off.
I finally found the specs that said my A/C is a newer 13,500btu. I am very hopeful it will start with the yamaha.
Finally, thanks for all the info 2manytoyz. Your data really did sell the unit for me. I was 100% honda 2000 until I saw this thread. If you ever need a reference from Yamaha for some sort of 'sponsorship', add me as a reference =).
Welcome to the growing club! Hope it does as well for you as it has for me and the many I've talked with. Be sure to post your personal experiences too. Good or bad, all posts help with the overall picture.
dixoncider you are the exception, I have a close friend who loves his yamaha's where are you located? if you want to get rid of it maybe I would be intrested?
We ran the dual Eu2000's to run our AC, worked out fine. But it was a matter of what support was available to us at the time. Which in our case was Honda at the time. There wasnt any real support for the Yamaha's at that time. But if we were to get one now, would look at the Yamaha 2800, a lot lighter than the 3000, has a longer run time than the 2400, and should run your AC.

Here is a quick update for potential purchasee's of the Yamaha.
As many of us, I too have to tinker. I did not have the Yamaha EF2400is home for 15 minutes before I took a drill to it =). I drilled a hole in the handle frame in order to secure a chain to the frame itself(Warning Ahead). I did this because the handles seem easily unbolted. A chain looped around the handles would not be very secure. Luck was on my side as I could have made a big mistake. I never thought to measure the distance needed to slide a long tanged padlock around the chain and get it through the hole without binding... It fit, but had I gone over 1/2 of an inch, I would have a hole for security and an additional hole to remind me of the lesson.
Moving the unit:
The unit was pretty easily moved with one able person. We had campers on one side, then on the other. Out of politeness I would move the gen to the opposite side of the site from our neighbors. It definately takes two hands.
Gassing up:
I filled the unit twice. If I had to guess, I used two to three gallons total. If I had to guess on run time.. Mmmm, maybe 20 hours?
I can tell you, you can gas up at 2pm and run to 7pm and still have plenty of gas in the tank.
Ooops my bad:
I did cause the Yamaha to have a moment of wierdness. I had inadvertantly set it on a couple of large leaves that proceeded to block the air intake screen. It started to cycling like it did not know if it wanted to go into high or low speed. Noticing the problem, I moved the unit and it ran flawlessly for the next 4 days.
Sound:
This is the big one everyone wants to know.. Frankly I was nervous as I knew the honda was quiet enough for me, and I had not heard the Yamaha in person. There were several Hondas near by, and I had the only Yamaha. In a sentence. In quiet mode, the Hondas seemed louder at times, and the Yamaha seemed louder at times... Go figure.
Upon startup I was relieved that the Yamaha seemed to be on par with the Honda 1000 that was running one site away. If you stood between them the Honda had a 'puttering' sound, and the Yamaha had a slightly more 'Whirrrring' sound. I walked to a Honda 2000 and it seemed to sound pretty similar. There was one Honda 2000 that was set in an area pretty thick with pine needles, that was more quiet than the rest of us. I suspect the pine needles absorbed some of the sound at the expense of a fire hazard.
At times, I could hear my Yamaha over the Honda, at times the Honda seemed more than my Yamaha. I'm sure that variables like wind direction and angles of surfaces near the gen play a big part in the perception of sound.
After 5 days of paying attention to every generator in the area I was left thinking the Honda and the Yamaha seemed pretty much equal. I also think that people more sensitive to higher drone sound would hear the Yamaha, and people sensitive to the puttering sound will hear the Honda.
All in All:
I am very pleased with the Yamaha's performance and ease of operation. It's not louder than the Honda, its not quieter than the Honda. I look forward to doing some air conditioning tests when the heat around here gets to 110. If it runs then, it will be the killer gen set.
