So far this year, we have had 43 days now of 100 degree plus days. And no rain. Our Elec. only this month for in an 1800 sq ft house was $464.00. We keep it around 75 degrees. Our unit is 10 yrs old. We have had energy efficient windows installed last year. We were told by the installers not to cover the windows with foil or such because it will break the seals in the window. We do have mini blinds that are kept shut and have plantation shudders in the dining room. We do not have the hot tub running this year but do have landscape lighting. I hate these high bills. Grrrrrrr
