The
Sure Start may be a slightly less expensive ($180.00 in 2012) alternative to the Smart Start.
With the Sure Start, my single Honda EU2000 starts the AC every time at 90+ degrees at 3500'.
In the same conditions, the Hard Start was not as reliable starting, but it was "slightly" better than without it.
Another way to start the AC that I played around with before I got the Sure Start was to start the compressor a few seconds before starting the air handler. This worked far better than the Hard Start alone and, with the Hard Start, it was was "almost" (but not quite) as reliable as with the Sure Start.
Notice that I said my EU2000 can start the AC. I did not say that I can run it at those temps and altitude. Alias, I am only able to run the AC with the single generator for about 20 to 30 minutes before the generator gives up. So a starting assist (Hard or Soft) is not a substitute for a generator that is sized to RUN the AC at the temperature and altitude that you wish it to work at.
Hope this helps,
Steve
