Deciding whether to set your air conditioning thermostat to seventy-six or seventy-eight degrees Fahrenheit depends on balancing personal comfort preferences against monthly energy efficiency goals. Energy conservation guidelines generally recommend setting your AC to seventy-eight degrees during summer months when you are home, as every degree lower increases your cooling energy consumption significantly. However, if seventy-eight degrees feels too warm or humid for your personal comfort due to local climate conditions or poor home insulation, setting the thermostat to seventy-six degrees is a reasonable compromise that maintains a cooler living space without overworking the equipment. You can enhance comfort at 78 degrees by running ceiling fans. You can verify that your chosen temperature is optimal when your family feels comfortable and monthly electricity bills remain manageable.
