25BHS with Coleman 13,500 BTU A/C: will Yamaha EF2400iSHC run it

Hi Folks,
I have read many threads on this topic, spoke with both Coleman and Yamaha, and thus far I have been unable to get a definitive yes or no on whether the gen will run the ac. The Coleman ac is model 8333E7564 and uses between 15.75 and 16.25 A on startup and pulls between 1000 and up to 4100 watts on startup. Coleman sais that the 4100 watts is absolute worst case scenario. I have read that some folks here are having no troubles with their 13,500 btu units and this genny however I am hoping to find someone who is running this exact combination. I am willing to install a hard start capacitor kit if needed. I do realize that the 3000 genny unit would likely be a safer choice however it won't fit easily under our tonneau cover and I am hoping to spare my back a few pounds.

From what I understand, the Yamaha was made specifically to run a 13500 btu AC. I would say with a hard start capacitor, you'd be golden.

If you are nervous about that, you could buy 2 champion or 2 Honda and pair em together. You can but 2. Brand new champion 2000 watt Benny's for $900

I own the Yamaha. I do not think it was made specifically to run AC units in trailers. It does not even have a 30 amp plug. You have to use an adapter which trailer companies, including Jayco, say never to use. That being said, using an adapter, mine ran the 13.5 AC unit in our 2011 Forest river 21SS every time and so far in 75 degree weather, it started the 15K unit in our Jayco 33RLDS. I am not sure if it will in warmer weather though. I love the Yamaha and at 75 lbs I can hoist it in the truck by myself..

Yes, the Yamaha EF2400iSHC will run a 13,500 BTU A/C, it's marketed to do so. Yamaha states: "This High Current model starts most high efficiency 13,500 btu AC in temperatures up to 110 F."

I ordered the 2400 yamaha generator today along with the supco spp6 capacitor, will let you know how it goes. Thanks for your help.

I didn't see a response from Zad so I thought I'd share my experience.

My A/C unit is an Airxcel 13.5K btu model 8333E7564. My Yamaha 2400ishc would start the A/C unit as long as I didn't have any other high power draw items running (microwave, coffee pot, electric grill, etc.). That said you could tell the generator was near max output and it typically took 6 ~ 8 seconds for the A/C unit to start. On a couple of occasion the generator overload would kick in and knock the generator off line. A second try after a few minutes to let pressure equalize would ultimately start the A/C unit.

Not satisfied to work the generator to the limit every time I started the A/C unit, today I install a Supco SPP6 start capacitor to see if there would be any improvement. I'm glad to inform that with the start capacitor installed the A/C unit would start within 1 second after turning the unit to the cool setting. The capacitor appears to add the required boost at start-up to prevent the generator from having to stay in a max output mode for 5 seconds or more to get the A/C running.

Installation of the start capacitor takes all of 2 minutes once you have the A/C shroud off and remove the access panel. The start capacitor has two leads. You clip one lead of the start capacitor to a terminal of the run capacitor (in my case where red wire is located) and the other start capacitor lead goes to the other run capacitor terminal (in my case where yellow wire is located). These are non-polarized capacitors (even though the diagram depicts polarized by the symbols "-|(-" ) so which lead of the start capacitor goes to which terminal of the run capacitor doesn't matter as long as they are opposing terminals.

For $15 and a half hour of your time it appears to be an easy solution in situations where a generator an A/C start-up are borderline.

Hope that 2400 works for you. My brother bought one and it wont run his 13.5 when you get over 6, 000ft or something else is running.

The higher altitude will reduce generator performance. Tell him to install a start capacitor ($20 and 30 minutes of labor) which will boost the power available to start the A/C unit.
