Playing around with our electricity usage data from the last 3 years. A/C switches to evening cool mode at 7pm. The laundry bump on weekends is also apparent (A/C program is the same on weekdays and weekends).
You can probably estimate A/C usage pretty well from this graphic. Red is warm season (May-September) and blue is cool season (all other times). The A/C switches to afternoon mode at 11am and doesn't run much for the next 3 hours. Then it keeps the house livable until the big cooldown at 7pm.
