76 in the day and 68 at night. Never really gets to 76 in the day until about 2:00, so my air basically shuts off at 7:30 and doesn't come on again until about 2:00. Then it bumps down to 73 about 7:00 & 68 at 10:00. A Nest thermostat is great! Highest bill I've ever had is $210. Average a little over $100.
You really shouldn't run an A/C below 68.
