They work here until we need them the most, then the humidity overwhelms them and you get a sauna. Not ideal for midsummer in the desert.Extremes anywhere are hard. Hopefully this year your hell months won’t last so long.
And guess fans would be useless. Have you tried evaporative coolers? I bought one last summer, but our summer turned very steamy and humid so it was useless. But when the humidity was low it worked fine.
