I'll have hubby get up and check the unit I usually have it set at 70 or 72 but I turned it down that low to try to coaxe some cold air out of it!! It's wierd.. It was working fine yesterday morning and I turned it up to about 76 since we were going out of town. We got back this evening and it was ridiculously hot!! Ugh I hope you are right and we can solve this!!
