I have central air. With the weather so nice, I've had no reason to run it so I've just been opening the windows. But on days when it's not windy, not much air comes in. So I decided to just turn on the "fan only" option on the control box (thermostat). This moves air quite nicely but what I need to know is how much electric is it using? Is it using less than if the A/C was activated? If it's roughly the same, I may go buy a couple window fans or just close the damn windows and leave the stupid A/C on.
Any knowledge out there on this?

Well, if the AC compressor is not running then it's using less juice to run just the fan. The AC unit really sucks up the juice (220v 60 amps). Running just the fan uses power, but far less than if run the AC w/ it.

No compressor...yah less juice.
However the ducting fans aren't the most efficient either...far from it.
The only advantage to running air duct fans is for the filtering of pollen/dust....if you're running a system that does a good job of filtering.
Else...invest in some window/pedestal/ceiling fans, and enjoy vastly improved airflow.

As mentioned, it’s the compressor that sucks the most juice, especially when it kicks on. That initial surge uses a lot of electricity, that’s what the A/C breakers are rated for, the initial surge.
The fan doesn’t use much electricity but make sure you have a good filter. Keep in mind too that the fan won’t cycle on and off like it does with the compressor while using the thermostat control.
When the weather is nice I put a box fan in the bathroom window and open the window on the front storm door. That way air is drawn through the whole house. Sometimes I’ll turn on the A/C fan too for a short time to help circulate the air more.

The compressor fan went out Memorial day weekend and man that sucked. It went out Saturday morning and we couldnt get anyone out there till Sunday afternoon...on top of that we live in TN so it was warm and humid in the house.
Made me think about not have AC when I lived in Cadillac Michigan and then I remembered it stayed around 75 in the summer.
