If I've done my math right on the A/C units, they pull a combined 8500 watts. It would only take them each running on average 15 minutes per hour to eat up 52 kWh per day.
Two 14 SEER units, one 3.5 ton, one 3 ton, and a 10 SEER 2 ton unit.
1 ton = 12,000 BTU.
(6.5 x 12000) / 14 + 2 x 12000 / 10 = 7971 watts.
The air handlers have 1/5 HP motors, call that another 150 watts per air handler, so we're up to 8500 watts at least.
52 kWh / 8.5 kW is a little over 6 hours, or 1/4 of the day.
To use less power and still have a comfortable home, I'd have to insulate it better and switch to smaller and more efficient A/C units. The units are sized properly according to:
