Location: Southern New Mexico | Does anyone have one or know if the yamaha ef 2500 will run a air conditioner? I found one and the guy only wants 500 for it but I can't find any info. I saw on another website that the ef2400 can run a 13500btu ac but that is a newer model. |

Location: western PA | The air conditioner needs ~ 12.5 amps to run. On a start up surge, it probably would need 16 + amps or so. The Yamaha puts out aprox 23 amps at a maximum load. So the Yamaha should handle the opperation of the air conditioner. I don't know what the running output of the generator is. It will be a figure less than the max output, one that the generator can handle on a continuous basis. Other than starting, this will be the most important specification. I'm guessing it would be aprox 25% less or about 16-17 amps, still enough for the A/C. The EF2500 was initially made many years ago. I would question the owner about its age and how many hours running time it now has. |

Location: Richmond, Ky | Gard, the problem comes in that as the A/C unit ages it gets harder to start, so the current draw goes up, and if the genset can't handle it, it's voltage drops and so the "trying" to start compressor draws more current to make up for the voltage drop and a never ending spiral downward, all the while it's damaging the compressor windings due to hi current being drawn. Just a guess here but the 2500 would be 2500 watts, that would equal to around 20 amps peak current draw. If it is a PSC compressor they might could switch it over to a capacitor start relay type all this will cost $$, but these type start so much faster and easier.
Happy Trails |

Location: Southern New Mexico | Thanks y'all. I did't follow half of that.... One AC is 4yrs old and a Coleman Mach and the other is a Coleman TSR ,no idea how old that one is. I think I will keep looking for a "bigger" generator. This one should work for my horse trailer with only the AC but not the camper with all the extra stuff in it. |

Location: Southern New Mexico | Oh, I forgot that I have an electric hot water heater in the horse trailer too. I'm thinking of swapping it out for a propane one when I re-do the inside of the trailer. I called a RV place and asked what size they would recomend and they said a 4000. Do I really need something that big?

Location: western PA | The generator size you need, will depend upon how many electrical devices you want to run at the same time. Air conditioners, ceramic heaters, blow driers, electric water heaters, microwave ovens, electric cooking utensils, all are power hungry appliances. If you want to run any two of these at the same time, the 4K figure is pretty accurate. ~3K will run one of those plus lights, a tv etc. ~2.5K will run one plus the lights. Everyone is different in his needs. You have to decide what you have, what you want and how much running multiple items concurrently is worth to you. BOL |

Location: Southern New Mexico | Thanks. Why can't they explain it that way in the generators description? I think the hotwater heater with the AC will make the 2500 to small. Oh well. I'll keep looking. Or I could turn off the AC when I take a shower?

Location: Indiana |  Just curious, Terri. If you have hot water, why would you need a heater? It's a water heater, not a hotwater heater. |
