Every summer this happens on my unit.
I live in the Southern California desert area - in the summer it get VERY hot here (July/August daytime temps are normally 100). I work with many people who like the unit at 75 degrees. I AM SORRY - 75 is too hot to work in and be running all over creation for 12 hours.
They complain that they are cold - think about that for a minute. It is 105 outside and they bring winter coats to work because they are "cold". Add like clockwork, these same people raise the thermostat up to 80 - 80 in the summer is bull.
"We need to go green -- save the environment - Oh PLEASE PEOPLE GET A LIFE.
START WORKING - LOG OFF FACEBOOK, GET OFF YOUR BUTT, AND HAUL IT - Then tell me your still cold!
Frankly, I like it on the cooler side around 70.
1 - I am a large guy and I would rather be cool and clean than sweaty and funky (visual - drip drip - you see my point!).
