G'day Russ
        Er Uhm, out of interest a couple of questions. When you ran the unit
was it
in a sealed area which is where it is intended or was it in the open out of
the crate?
        The way these things work in Australia (shouldn't be different over
your
way) is that to get the most effective cooling out of them the vent should
be closed forcing the unit to recycle the rooms air. Gradually this has the
effect of cooling the cooler interior air instead of cooling hot outside
air. 5000btu will struggle unless you mount it correctly and then close the
vent. It's much the same with a cars airconditioning. If the airconditioner
is not mounted when testing it you will always cool the outside air. You
are still getting a temp drop of 20 degrees from it don't forget even now.
fwiw, my house has 3 x 23000 btu airconditioners and they work much much
better with the vents closed.

Cheers
