Coleman or Supco hard start kit?

If your coleman 9,000 BTU is like mine,

1) Coleman reduced the LRA noticeably from the 13.5K units
2) they installed a much better matched starting cap

w/o doing anything, I can easily start and run my coleman 9,000BTU unit in my small trailer with my honda 2000 in eco mode at altituded at least to 6,000Ft on very hot days with no problem.

honda doesn't need to grunt much at all to start it.

Now the 13.5K BTU units, completely the opposite experience.

Thank you for the fast response, ktmrfs.
Yes, I am running a rather new 9000 BTU Mach (although I'm told the latest units have been upped to 9200 BTU).
The LRA current is 58.4 amps. Running current is 9.0

The exact problem is that the first start of the morning will throw my Honda EU2000i into overload... Even when its not in ECO mode!
Note that every start after that is perfectly fine all day long.


I just ordered a 5-2-1 CSR-U1 compressor saver. It is a three wire device that actually comes with a straight forward wiring diagram. Hopefully it will cut the starting load just enough to keep the EU2000i from going into overload before the A/C compressor gets up to speed on that first start of the day.



Please also note that my Honda EU2000i runs on propane which reduces it's output capacity by about 10%.
Propane is clean and convenient but has less energy than gasoline.

Thanks again for the reply! :C
