Is 78 too high for a thermostat in summer?

Whether 78 degrees Fahrenheit (roughly 26 degrees Celsius) is too high for a summer thermostat setting depends entirely on personal comfort tolerance, indoor humidity levels, and health considerations. While energy efficiency organizations and utility companies frequently recommend setting thermostats to 78 degrees while you are home and active to minimize monthly electricity bills and reduce strain on your air conditioning system, many individuals find this temperature uncomfortably warm and stuffy. If indoor humidity is high, 78 degrees can feel significantly warmer due to reduced sweat evaporation. To make 78 degrees feel more pleasant, you can run ceiling fans to create a cooling wind-chill effect on human skin. You can verify that your temperature choice is effective by balancing your personal comfort against your monthly cooling expenses.
