1. The standard air conditioning temperature setting is 28°C

By simply raising the air conditioning temperature setting by 1 degree Celsius, electricity consumption can be reduced by approximately 10 to 13%.Air conditioning in summer is at room temperature of 28℃" We recommend that you use a fan or air circulator to lower the perceived temperature and maintain comfort, even if the 28°C setting feels hot.
- Every 1°C increase in temperature reduces electricity bills by approximately 10%
- Adjust the temperature to a comfortable range, aiming for 28℃.
- The perceived temperature also changes depending on humidity and wind.
Set the air conditioning temperature to 28°C as a base temperature and adjust it according to your family's physical condition and comfort.
2. How to use wind direction and volume correctly
When cooling, set the airflow direction to "horizontal" to make it easier for cool air to spread throughout the room. The "auto" airflow mode is the most efficient, keeping the room temperature comfortable while reducing power consumption.
- Wind direction "horizontal" is most effective for saving electricity
- The best setting for airflow is "Automatic"
- Circulate the air with a fan or air circulator
Set the airflow direction to horizontal and the air volume to automatic, and use a fan in combination to improve cooling efficiency.
3. Cleaning the filter and outdoor unit
If the air conditioner filter is dirty, the cooling efficiency will decrease significantly. Clean the filter about once every two weeks. Also, you can reduce power consumption by not placing objects around the outdoor unit and avoiding direct sunlight.
- Cleaning the filter saves you about 1,000 yen a year
- Install the outdoor unit in the shade and do not block the air outlet.
By regularly cleaning the filters and making improvements to the outdoor unit, you can significantly reduce your electricity bills for air conditioning.
4. How to use air conditioning and when to use it
If you are going out for a short time, leaving the air conditioner on may result in lower electricity bills. Frequent on/off switching increases power consumption, so if you are going out for less than 30 minutes, it is recommended that you leave the air conditioner on.
- If you are going out for a short time, leave the air conditioning on.
- Always turn off the power when going out for an extended period of time
Turn the air conditioning on and off depending on how long you will be away from home.

5. Windows, curtains and insulation
Preventing heat from entering through windows will greatly improve the efficiency of your air conditioning. Use heat-blocking curtains or insulating sheets, and keep curtains closed during the day to block out direct sunlight.
- Prevent the room temperature from rising by using heat-shielding curtains and insulation sheets
- Close the curtains during the day to keep out heat
Taking measures against heat from windows will increase the efficiency of air conditioning and lead to savings on electricity bills.
6. Air conditioning savings ideas for the whole family
By spending time together as a family in one room, you can reduce the number of air conditioners you use. We also recommend using cooling products and cooling towels.
- Stay in one room and use fewer air conditioners
- Lower your perceived temperature with cooling products and cooling towels
By working together as a family to devise smart ways to use air conditioning, you can save money without any effort.
