You could conceivably get one of those evaporating portable A/C units and set it up in a small room, if you could bear the extra expense (they cost around $250 per unit). I bought a couple of those units this year to cool down my upstairs guest rooms, which get absolutely no cooling from my central a/c. They evaporate the condensation, and require only a window vent to exhaust the hot air.
Around here, it just pisses off the black mold and makes it grow faster.
Next year I'll have bigger ACs, and maybe keep it down into the 80s inside. ;)
