Optimal temperature settings can make a big difference. Set your AC to a moderate temperature, ideally around 24-25°C, for a balance between comfort and energy efficiency.

Keep your AC unit well-maintained by cleaning or replacing air filters regularly. Dirty filters restrict airflow, making your AC work harder and consume more energy.

Check for leaks around doors, windows, and ducts, and seal them properly to prevent cooled air from escaping. 

Direct sunlight can significantly increase indoor temperatures. Keep blinds, curtains, or shades closed during the hottest parts of the day to prevent heat from entering your home.

If your AC has energy-saving features like sleep mode or eco mode, use them. These features adjust the AC's operation to optimize energy usage without compromising comfort.

Choose one with a high energy efficiency rating (EER or SEER). Energy-efficient models consume less power while providing the same cooling capacity.
