We use a programmable setback thermostat for both heating and AC. During the warm days, our house temperature may get as high as 86 degrees, which is OK because we are usually outside. After 5 PM the thermostat lowers the demand temperature to 78. While the AC hardly runs between 8 AM and 5 PM, it runs continuously until the house cools down to 78. Do I use more electricity trying to cool the house from this higher temp, or would it be more efficient to just keep the temperature around 80 - 82degrees during the day so the compressor doesn't need to run as long in the evening? Am I being penny-wise and pound foolish?

According to a U.S. Department of Energy fact sheet, Automatic and Programmable Thermostats, it is a common misconception that a
furnace works harder than normal to cool a space back to a comfortable temperature after the thermostat has been set back a certain amount, resulting in little or no savings. This misconception has been dispelled by years of research
and numerous studies.

The general rule of thumb is that energy savings are typically one percent of space heating or cooling energy per degree of temperature setback/setforward per eight hour period of setback/setforward (1% per °F per 8 hrs). For example, setting the temperature up from 74 °F to 78 °F during the night for 12 hours would result in an energy savings of 6% of your COOLING energy use. Since cooling is a percentage of your overall electricity bill, check the
Home Energy Use Calculator to get an estimate of your overall energy savings on your electric bill. As an example, a typical 2500 ft² home in Richmond, VA consumes 25 percent of its electric bill in cooling, and will see an overall energy savings of 1.5 percent of electricity (6 percent of 25 percent) with the temperature setforward parameters.
