Korean summers can be extremely hot and humid. If you are an international student, traveler, exchange student, or staying in Korea for only a few months, installing a traditional wall-mounted air conditioner can be difficult.
That is why many people in Korea use window air conditioners, known in Korean as 창문형 에어컨.
What Is a Window Air Conditioner?
A window air conditioner is a compact AC unit that fits into a window frame. Unlike traditional split-system air conditioners, it usually does not require drilling, outdoor unit installation, or major construction.
This makes it a practical choice for people living in rentals, dorms, officetels, or small studio apartments in Korea.
Why Foreigners in Korea Like Window Air Conditioners
1. Easy Installation
Many Korean rental rooms do not allow permanent air conditioner installation. Window AC units are easier to install and can often be removed when you move out.
2. Good for Short-Term Stays
If you are staying in Korea for one semester, a few months, or one summer, buying a full wall-mounted air conditioner may not be worth it. A window AC is much easier to manage.
3. Works Well in Small Korean Rooms
Window air conditioners are especially useful for small spaces such as one-room apartments, officetels, goshiwons, and student housing.

Tips Before Buying
Check Your Window Type
Korean apartments often have sliding windows, double windows, or security bars. Always measure your window before buying.
Consider Noise Level
Some cheaper models can be noisy at night. If you are sensitive to sound, look for models with sleep mode, low-noise mode, or inverter technology.
Think About Electricity Bills
Summer electricity bills in Korea can increase quickly. Using eco mode, timers, curtains, and proper insulation can help reduce costs.
Final Thoughts
If you are staying in Korea temporarily, a window air conditioner can be one of the smartest ways to survive the hot Korean summer.
It is renter-friendly, relatively affordable, and useful for small Korean apartments. For many foreigners, it is much easier than installing a full wall-mounted air conditioner in a short-term rental.
Especially during July and August, having your own cooling system can make life in Korea much more comfortable.
