Many people have the habit of turning off the air conditioner when they leave the room, and then turning it back on because they think it will save electricity. However, continuously turning the air conditioner on and off actually consumes more energy and harms the device. So how long should you turn off the air conditioner when you leave?
How long should you turn off the air conditioner when you go out?
According to manufacturers, if you only go out for a short period of time (less than 1 hour), you should not turn off the air conditioner and then turn it back on, especially when using Inverter air conditioners.
The reason is that each time you turn on the air conditioner again, the device needs to start up with maximum power to generate cool air. This is considered the most energy-consuming process of an air conditioner. Some studies have shown that the air conditioner will need to consume about 3 times more electricity compared to operating at the initially set temperature.
In addition to consuming more electricity, turning the air conditioner on and off multiple times a day also reduces the lifespan of the compressor and other motors in the indoor and outdoor units.
If you go out for a short period of time, you should increase the air conditioner temperature to around 28 degrees Celsius or higher and set the fan speed to the lowest level to maintain a cool environment in the room without consuming too much energy.
Note: If you have to go out for a long time, in addition to turning off the air conditioner with the remote control, you should also switch off the circuit breaker to save a significant amount of electricity.

How many minutes should you turn off the air conditioner before going out?
Many people often have the habit of turning off the air conditioner and leaving the room right away, which is extremely harmful to health and a waste of electricity.
When you step out of the air-conditioned room directly, the ambient temperature will change suddenly, especially on hot sunny days outside. If this temperature difference is large, it can cause heat shock (shortness of breath, hallucinations, disorientation, fainting, etc.), which is not good for your health.
Therefore, if you plan to go out, you should turn off the air conditioner about 10-30 minutes in advance, while gradually opening windows and the main door to allow for airflow. This will help your body gradually adapt to the ambient temperature outside, prevent the risk of heat shock.
How to use the air conditioner most energy-efficiently
To use the air conditioner efficiently and extend its lifespan, consumers can consider and implement the following methods:
Regularly clean and maintain the air conditioner to increase its efficiency.
Close the room door when using the air conditioner to prevent heat loss.
Do not constantly turn the air conditioner on and off.
Turn off the air conditioner 30 minutes before going out to ensure the health of the user, avoid heat shock, and also prevent wasted electricity consumption.
Set the air conditioner temperature to a suitable level of 25-27 degrees Celsius.
If you have to use the air conditioner 24/7, you should choose an Inverter air conditioner to optimize energy savings compared to non-Inverter air conditioners.
