Sorry that I haven't responded until now. The Yamaha is 4000W with 4500W surge. Fivers with two a/c's come with a 5500W generator. Looking at the specs on some air conditioners a 15k unit takes 3500W to start up and 1500W to run. A 13.5k unit takes 2750W to start and 1250W to run.
Total start power= 6250W Total run = 2750W
Starting is the problem. My best bet to run both with the Yamaha would be to start one up and then the other and make sure that both could never try to start at the same time as this is when damage to the compressor would occur. I guess leave the thermostat in the bedroom as low as possible so that it never shuts off and let the other unit cycle. Then come night, shut off the living room a/c completely.
If this is too much trouble then I guess the safest bet would be to wire in a separate plug for the bedroom a/c and run it off of the Hondas. It's gonna be a real pain carrying around 3 generators though.
I may have to end up getting a Yamaha 5500W which is 6300W surge. It also has the advantage of having both 120V and 240V which is convenient as that is what my water well pump runs off of.
