Optimal AC Settings for Energy Savings

To balance thermal comfort and energy efficiency, it is recommended to set your AC at 24-26°C in most regions. This temperature range not only provides a comfortable indoor environment but also helps in reducing electricity consumption. Here are some additional tips for maximizing energy savings:

  1. Use Ceiling Fans: Ceiling fans can help circulate cool air more efficiently, allowing you to set the thermostat a bit higher.
  2. Insulate Your Home: Proper insulation helps maintain indoor temperatures, reducing the load on your AC.
  3. Regular Maintenance: Clean filters and regular servicing ensure the AC operates efficiently.
  4. Use Programmable Thermostats: These devices can help manage temperature settings automatically based on your schedule, avoiding unnecessary cooling when you’re not home.
  5. Seal Leaks: Ensure windows and doors are well-sealed to prevent cool air from escaping and warm air from entering.
  6. Shade Windows: Use curtains or blinds to block direct sunlight, especially during peak hours, to reduce the cooling load.


Understanding the thermal comfort temperatures in different regions of India and setting your AC accordingly can lead to significant energy savings. Maintaining the AC temperature between 24-26°C is generally recommended for optimal comfort and efficiency. By combining this with energy-saving practices, you can enjoy a comfortable indoor environment while keeping your electricity bills in check.
