The problems come in when the furniture and furnishings get hot and then give off that heat for hours to come. I am sure you have touched the counter and it has been warm. That heat is radiated into the room when the room is cooler and then the a/c has to work to cool it down again. Think of a steering wheel in a car. Generally speaking letting a place warm up and then cool down makes the a/c work extra hard for a longer time during the cool down process, than it would have if it had just maintained a constant temperature range all day. Maintaining uses very little electricity and does not wear on the machine very much. Going from a place that is in the 90's or even more to the mid to lower 70's makes the a/c work at max output for a long time, costing a fortune and wearing out the parts faster. Try each for a month and see what is cheaper/better for you. Try and pick months that are about equal in temperatures. Maybe keep a log that shows the highs and lows for each day.
