Ugh.....we had our highest bill ever this July $368. for one month. We do not keep it cold (air does not come on till 82 degrees) and only override it for a few hours a day. Here in AZ we are at our worst months of the year...hubby got in his car yesterday when he came out of work and the thermometer in the car read 121 degrees. Now that's hot! Of course when some folks are shoveling snow and are all bundled up we are still in shorts and flip flops. Guess summer heat is the price we pay for that.
