I keep my humidor on the bottom shelf of the endtable in the living room. I find that it is much cooler down near the floor. The heat and humidity has been pretty intense here in WI too. Since I have my own place now and have to pay the bills, I have only used the A/C for about a week out of the whole summer. I am never home during the day and I leave the windows open, luckily we live in a small town where there are not too many problems. I even leave my patio door open sometimes. I just leave a fan in the window of the living room to keep the temp. down in there. Leaving the humi on or near the floor, I have found keeps it at a nice 70-75 degrees. Also, the needle has not moved off the 68% humidity mark, so that works great for me!
