Although fall has arrived, there are still likely to be several more days in Sacramento where temperatures are above 90 degrees and you will be relying on your AC to stay cool. This means the question of what temperature to set your AC at that will meet the needs of both efficiency and comfort still needs to be answered.
The recommended AC setting with a central air conditioner is between 72 to 78 degrees for homes in Northern California. A temperature in this range is low enough to keep most people cool while avoiding overworking your air conditioner and running up costly utility bills.
Setting your AC lower than 72 degrees carries with it a number of risks. Cooling your home to 70 degrees or lower when it is 90 degrees outside will naturally be expensive as this exceeds the work that most insulation can do and leaves your AC to do a large part of the cooling work. This can overwork your air conditioner, potentially leading to expensive repairs or leaving you without AC altogether.
By sticking with a temperature at 72 degrees or above, you will increase the chance that your AC will run reliably for the rest of summer and for many years to come.
Of course, not every person is comfortable when it is 72+ degrees. But those people who run a little warmer can help keep their homes cooler with a few additional energy efficient cooling measures that do not rely on AC:
