I would like to know what is more energy efficient: Using central air with ceiling fans OR using window fans with ceiling fans to cool the house. I really wonder because the central air only comes on when needed but the window fans are running constantly and are set at the highest settings. Does anyone know?

Refrigerated air conditioning is WAAAAAAAAAAY more expensive than using window/room fans. If you can be comfortable using only window fans, use them. Running a simple fan (or four), even on high uses very little electricity. Cooling the air is what makes an air conditioner so expensive to run. The fan in it is the cheap part.
We have an air conditioner but haven't used it for a couple of years (living in California), not since we installed an attic fan. The temperature could be just over 100 degrees F outside and it would (maybe) get to 76 degrees F inside (by 7pm). Very comfortable for us.
