> Depending on where you live you can save more money by simply using a good size fan blowing cold air into the house at night during the summer. I have a whole-house fan (Western Massachusetts), and the "where you live" caveat is a biggie. It depends on sun exposure, air movement, humidity and local factors (like air flow through the home). We've found that running the fan at night keeps the house cool through mid-morning (on warm days with low humidity) but after that the house warms up very quickly and that's when the A/C is turned on. I'm happy you had a good experience with a large fan but don't automatically assume that it's a proper solution for other applications.
