My apartment has central air, but I haven't turned it on yet. Fortunately, I was out and about today for a meeting, so didn't have to be home. But also, I've found in this type of weather, keeping the windows closed or minimally open, and the shades drawn slows the heating of my place. And when the sun sets, I can pop a window fan in to bring in cool air from the outside.
Of course, there will come a point where I throw the AC on - usually just setting it to 76 during the day to keep the humidity down.
