On hot days, air conditioning becomes a "savior" in every family. However, many people still do not really know how to use air conditioning effectively and save electricity. One of the common questions is: When turning on the air conditioning, should the door be closed or left open?

It seems simple, but it turns out that not everyone does it right.

Answer: Should close the door when turning on the air conditioning

When turning on the air conditioning, closing the door is mandatory if you want to cool quickly, maintain a stable temperature and save electricity. The air conditioner works by sucking in air from the room, cooling it and blowing it back. If the door is left open, hot air from outside will continuously flow in, causing the air conditioner to work harder to maintain the temperature as initially set.

This not only costs you electricity, but also reduces the life of the device due to having to operate at a higher intensity. Furthermore, when cold air escapes and is continuously replaced by hot, humid air, the humidity in the room will increase, causing discomfort and possibly affecting health, especially for the elderly and children.

However, the room should not be too stuffy and stuffy
Although it is necessary to close it, the room should not be too stuffy. The air in a closed air-conditioned room for a long time can become stagnant, lacking oxygen, causing a feeling of fatigue and lethargy. Especially if the room does not have a ventilation fan or the windows are not opened regularly, the air quality will be affected.

The solution is to open the door or window slightly for a few minutes in the early morning or late afternoon, when the outside air is cool, to exchange air. In addition, you can install a ventilation fan or air purifier to improve the air quality in the room while still maintaining the cooling effect of the air conditioner.

Additional notes for effective use of the air conditioner:
Do not turn the air conditioner on and off continuously - this consumes much more electricity than maintaining a stable temperature.

The ideal temperature should be set at 26-28 degrees Celsius, which is both cool and energy-saving, without causing thermal shock.

Use an electric fan to support the circulation of cold air, helping to cool faster without having to lower the temperature.

Clean the air conditioner periodically to ensure the machine operates smoothly and does not waste electricity due to accumulated dust.

When turning on the air conditioner, close the door to achieve optimal cooling efficiency and save electricity costs. However, do not forget to create suitable ventilation conditions at reasonable times so that the air in the room circulates better. Although it seems simple, many people still make mistakes in using air conditioners, causing electricity bills to increase while the cooling efficiency is not as expected.
