Tip to save energy when using air conditioning is to use the “Sleep” button – the most effective power-saving mode.
1. What is the function of the “Sleep” button?
The Sleep mode is designed to balance cooling efficiency and energy savings during the night – when the human body is more sensitive to temperature changes.
Specifically, when the Sleep button is activated, the air conditioner will automatically increase the temperature gradually (usually by 0.5 – 1 degree Celsius per hour) after you fall asleep. This helps:
-
Save energy as the compressor doesn’t have to run continuously at a deep cold level.
-
Protect your health by avoiding extremely low temperatures, preventing colds, sore throats, and nasal congestion early in the morning.
-
Prolong the lifespan of the air conditioner by avoiding overloading it for extended periods.

2. How much money can you save each month?
According to electrical appliance experts, a 1HP (9000 BTU) air conditioner running continuously throughout the night for 8 – 10 hours a day can consume approximately 3 – 4 units of electricity per day.
By using Sleep mode, power consumption can be reduced by 15 – 25%, saving:
-
About 0.5 – 1 unit of electricity every night,
-
Equivalent to 15 – 30 units of electricity per month,
-
At the average electricity rate, you can save $6 – $8 per month with just a simple button press.
How to properly use the Sleep mode
-
Use the remote control to find the button with the word “SLEEP” or the moon/sleep symbol (depending on the brand).
-
Press this button after setting the initial comfortable temperature (usually 26 – 27°C).
-
The system will automatically adjust the temperature over time without any further intervention from you.
-
There is no need to turn on additional fans, as Sleep mode already optimizes a gentle, soothing airflow.
A small note to save even more energy when using the air conditioner at night
-
Avoid setting the temperature too low (below 25°C) – it wastes energy and can make you feel too cold in the middle of the night.
-
Keep doors closed, use thermal curtains, and prevent drafts to ensure the air conditioner doesn’t have to work continuously.
-
Regularly clean the air filter to help the machine cool faster and consume less energy.
-
Turn off heat-generating devices in the room, such as incandescent lights and laptops on charge…
Many people mistakenly believe that staying cool requires spending a lot of money. However, the truth is that by using the features of your appliances correctly, you can enjoy a comfortable life while also keeping your finances in check. Remember, each time you press the Sleep button, you’re reducing financial stress while also taking care of your family’s health in a smart way!
