Here in South Texas I keep my house at 78° during the daytime in A/C season (that's typically March-November, plus some days the other months). If the ceiling fan's aren't on, and the air isn't moving around properly, it can easily get up to 82°. It's perfectly comfortable. (You acclimate to it)
Understand, the average high is in the mid to upper 90's and trying to get a home a/c to cover a 20+ temperature difference is difficult and significantly drives up the monthly power bill.
