Setting air conditioning cooling temperatures to no less than 26 °C can save energy*
Fans use less energy than air-conditioners
Consider zoning cooling, including closing vents and doors in areas you are not using
Use the auto setting instead of the on setting, so your air-con only uses energy when needed
Avoid placing home entertainment systems and lamps near air-conditioning thermostats. Electronics can add heat to the air, causing the system to work harder than necessary
