Can you tolerate 80 degrees? that would help.
MadSci, if it were just me, yes I could handle going without the a/c, we did it for many years while my children were growing up... But, my foster daughter cannot handle the heat... Above 74 degrees she gets a bit drowsy, Above 76 degrees, and she falls asleep... above 80, she goes into seizures. She was put into that situation once, while she was at school, apparently their a/c broke and they didnt bother to call any parents... I dont know exactly how hot it got before she went into seizures, but the school swears it didnt get over 80.... So, I have to be very careful of that.... At this point, I think my best bet will be putting a window unit in one room, and keeping her in that room while we are home.... If I can just finish out this month without turning on the a/c, I will be happy!!!
The friend who told me about the paint, said he put it on his roof, and his bills went down from over 300 to around 170, so close to cutting the bill in half.... He is even willing to paint my roof for me, so cant beat that!
I also sent an email to the people with the free a/c information.... According to them, because of where I live, this system would not benefit me (I cant believe a sales person would say that) but did suggest that if I could find someone who would be able to drill (using an auger??) holes straight down then it would help.... here is what he wrote
For a climate like yours, we have come to mostly suggest the "vertical version" of the tubes, where the tubes are actually inside a whole bunch of very shallow wells (like water wells, but not nearly as deep). Depending on whether you could find someone who would make a bunch (maybe 30) such shallow boreholes (maybe 30 feet deep), and what they would charge you for that, you might be able to benefit from that version (which is slightly different in that it is filled with water instead of air). But even then, you would certainly still need to use your existing A/C to do the final cooling.
If you could find someone who would be willing to bore those holes for maybe $200, I might think it was worth considering. But they would probably try to get you to pay $1,000 or more, and then, absolutely no. I guess I am thinking a High school kid with one of those hand-turned auger-type post-hole diggers, because if any larger equipment was required, they would try to charge you way too much.
So, a little research on my part and see if I can find people willing and able to do this.... We shall see... Its refreshing to know, that there are still people out there honest enough to say my product wont work for you!!!!
