26 degrees C rule and combined with electric fans
Air conditioners are the most energy-consuming devices in the summer. Many people have a habit of lowering the temperature very low, about 18 to 20 degrees Celsius, as soon as they enter the room to cool down quickly.
However, this action forces the compressor to operate at full capacity, causing electricity consumption and increasing the risk of heat shock when stepping outside.
For effective use, people should set the air conditioner to 26 to 28 degrees Celsius. This is the ideal temperature threshold for the body to feel comfortable and the machine to operate stably.
In addition, turning on an electric fan in light wind mode will help circulate cold air evenly throughout the room, creating a cooler feeling of 2 to 3 degrees Celsius compared to reality without lowering the air conditioner temperature.

Utilize curtains to insulate the house
A large amount of heat from sunlight can be transmitted directly through the glass door and absorbed into the house, forcing the cooling system to work harder.
During hot sunny hours from 10 am to 4 pm, families should close windows and draw curtains to prevent heat from entering.
Prioritizing the use of light curtains such as white, cream or beige is also more effective, because they have better heat reflection than dark colors that easily absorb heat.
Periodic air conditioning filter net cleaning
After a period of continuous use, dust will cling densely to the air conditioner's filter, reducing cooling efficiency. At this time, the machine must operate more energy-consumingly, consume more electricity, but the room is not cool enough.
During the peak summer months, users should maintain the habit of removing the filter and washing it off with water every two to three weeks. This simple maintenance can help save from 5 to 15% of the device's electricity consumption.
Remove plugs from electrical devices when not in use
Many people mistakenly believe that devices turned off by remote control means they have stopped consuming electricity. In fact, devices such as TVs, phone chargers, computers, or microwaves, when in standby mode, still silently consume a certain amount of electricity.
People should develop the habit of completely removing the plug or turning off the switches of electronic devices when they do not need to use them, especially before going to bed or when leaving the house.

Limit the use of heat-generating devices during peak hours
Devices such as washing machines, irons, ovens, or clothes dryers not only consume a large amount of electricity but also emit a significant amount of heat, making the air in the house even more stuffy.
To reduce the load on the electrical system and keep the house cool, families should avoid using these devices during peak hours, usually from 11:30 am to 2:30 pm and from 8 pm to 10 pm. Moving laundry and ironing activities to early morning or late evening is a reasonable alternative solution.
Saving electricity in the hot season does not require people to sacrifice comfort, but comes from small changes in thinking and daily living habits.
Regularly applying the above solutions not only helps protect the family budget but also joins hands to reduce pressure on the national power grid system during peak periods.
