I program mine to run less when we’re not home. On top of that I set a “super cool” routine on weekends when it’s going to be hot outside.
You see, the a/c is most efficient when it’s cooler already. So in the last hour of darkness in the summer I set it to run down to 68 or so. Then it doesn’t have to run as long to do that. Then it doesn’t have to run again for several hours as the temperature is set back to 72.
I also clean the outside coils annually and put up a sun sail so that the outside unit is shaded all day. This has helped save a lot of money along with the thermostat programming.
