So I am anti AC in my house. It is a 2 story house (1,800 sqft) and the top story gets quite warm. I have a fan in my room that I put on my window (http://www.lowes.com/pd_95021-1621-3...3D2&facetInfo=) that I run from basically 6pm to 830am the next day.
It keeps my room cool especially at night. Now one of my roommates has been complaining about how hot it is at night. Now first off, I charge my roommates $700 a month which includes utilities. In other words they dont have to worry about how much water they use or if they leave their lights on. I am now realizing after a couple years of doing it this way, that that was a bad decision. Last night I am woken up to the sound of my AC on. My roommate had turned it on.
In most cases I wouldn't have cared, especially if he asked me. He didn't ask, and all the windows down stairs and in the bed rooms were open (with the exception of his). I turned it off obviously and we got into it this morning about it.
I suggested we all split the utilities and he compained that he didn't want to pay for AC, its too expensive...funny he says that...
Ok so sorry for the long part above, my question is, what would be more efficient...have 3 of those box fans or running the AC at about 72 for the same amount of time?
