If my house was 88 degrees I would melt faster than an xp without a sink. I keep mine on 75-70 here is arizona, and withall my goodies in the house running most of the time, I still manage to only run around $120 a month for power, that is my and my girl and all my fish living here. To spend a little extra $ being comphy is 100x more worth it to me than be sitting in sweat miserable and saving some coin, that is just to me, also ac is usually very dry and I praise the guy for simple solutions when you have limited funds. I would do a similar thing but my ac vents are up to high to pipe anything that would not look like marioland in my office. I give the kid 7/10 skirts up for the cool idea on a budget
