How to Request Air Conditioning on Korean Subways via Text Message in Summer
Summer in Korea can be extremely hot and humid, especially during the peak months of July and August. The temperatures often rise above 30°C (86°F), and the humidity can make commuting feel unbearable, particularly on crowded subway trains. Although Korean subways are generally well air-conditioned, there are still moments when the cooling feels insufficient, especially in older trains or during rush hours when the body heat of hundreds of passengers can overwhelm the cooling system.
Many passengers are unaware that there is a simple, official way to request air conditioning adjustments via text message while riding the subway in Korea. This system was established to ensure a comfortable commuting experience for everyone, and it’s quite easy to use.
What Is the Subway Air Conditioning Text Request System?
The subway air conditioning text request system is a service provided by the Seoul Metro and other major subway operators in Korea. It allows passengers to directly request an adjustment to the air conditioning level in the train they are currently on. This is particularly useful when you feel that the train is too hot or too cold.
Rather than waiting for the train operator to manually notice the discomfort of passengers, this system gives commuters a direct communication channel. By sending a simple text message with the appropriate details, you can request the cooling system to be adjusted in real time.
Why Is This System Important?
Korean subway trains aim to maintain a balanced indoor temperature during summer, typically around 26°C (78.8°F). However, due to varying conditions—such as train congestion, differences between new and old trains, and technical limitations—some passengers may experience discomfort. Some trains might feel too warm, while others can feel overly cold.
To address this, the text request system was implemented to allow quick, passenger-driven feedback. It ensures that the needs of all riders can be considered and responded to efficiently.
How to Use the Subway Air Conditioning Request System
Here’s a step-by-step guide to requesting air conditioning adjustments via text while riding the subway in Korea.
1. Identify the Train Information
Each subway car has a unique identification number, which is typically displayed near the doors or above the windows. This number is crucial because it tells the subway operators exactly which train and car you are riding in.
Before sending a text message, make sure to note the following:
-
Subway Line Number (e.g., Line 2)
-
Train Number (displayed inside the train)
-
Car Number (usually written on the door or wall)
2. Prepare the Text Message
Compose a message in the following format:
-
Subway Line / Train Number / Car Number / Request
Example:
You can write the message in Korean or English, but for faster processing, Korean is generally preferred.
3. Send to the Correct Phone Number
Each subway operator has a dedicated number for these requests. For Seoul Metro (Lines 1 to 4), the number is 1577-1234. Other subway lines such as Line 5, 6, 7, 8 (Seoul Metro) and Line 9 may have their own numbers, which are typically displayed inside the train.
Always check the information stickers posted inside the car for the correct number.
4. Wait for Adjustment
Once the text message is received, the train operator will review the request and adjust the air conditioning settings if necessary. Response times may vary, but in most cases, adjustments are made within a few minutes.
It is important to note that the operators will balance the request with the general comfort of all passengers. If many passengers have requested a cooler environment, it is likely they will increase the air conditioning immediately.
Tips for Using the System Effectively
-
Be specific in your request. Mention if it is too hot or too cold and which specific car you are in.
-
Politeness is appreciated. Subway operators are more responsive to courteous requests.
-
Consider other passengers. If the car is not crowded, the operator might maintain moderate cooling to balance comfort and energy efficiency.
Additional Ways to Improve Subway Comfort
Aside from text requests, Korean subway authorities also conduct regular monitoring of temperatures inside the cars using sensors and passenger feedback.
Some newer trains are equipped with automatic temperature control systems that adjust cooling based on the number of passengers. Additionally, many subway cars now offer cool zones and warm zones, allowing passengers to select their preferred area.
Conclusion
The air conditioning text request system on Korean subways is an excellent example of passenger-centered service. It provides commuters with a simple, real-time solution to improve their travel experience, especially during Korea’s sweltering summers.
By learning how to use this system properly, you can ensure a more pleasant journey—not just for yourself, but for everyone sharing the ride. The next time you find yourself sweating on a subway car, remember that a quick text can make all the difference.
