AC electricity bills — cut them this way
Many households are shocked when the summer electricity bill arrives. Just tweaking your AC habits a little can save over ₩20,000–30,000 a month. We've compiled methods with proven real savings — set temperature, filter care, and even usage time bands.
As of July 2024 · referencing KEPCO rate tables
The bill difference a 1-degree change makes
Raising the AC set temperature by 1°C cuts power use by about 7%. Rather than setting it as low as possible, maintaining the right temperature is key.
| Set temp | Est. monthly bill | Savings rate |
|---|---|---|
| 22°C | approx. ₩95,000 | Baseline |
| 24°C | approx. ₩81,000 | approx. 15% saved |
| 26°C | approx. ₩68,000 | approx. 28% saved |
Continuous running beats switching on and off
An AC consumes the most power on first startup, cooling the room down. Rather than switching off and on every time you step out briefly, for outings within 2 hours it's more power-efficient to leave it on and just raise the temperature slightly.
๐ Use dehumidify mode
In humid rainy season, dehumidify mode cuts power use by about 30% versus cooling.
๐ Pair with a circulator
Aids air circulation, lowering felt temperature by 2–3°C so you can raise the set temperature.
๐ Sleep timer function
Auto-adjusts temperature in the small hours, preventing unnecessary cooling.
๐ช Block door gaps
Blocking cool-air loss with weatherstrip or curtains reduces how often it restarts.
Filter cleaning alone saves 5% on the bill
When dust piles up on the AC filter, airflow worsens and more power is needed to hold the same temperature. We recommend cleaning the filter once every 2 weeks, and installing a shade around the outdoor unit boosts cooling efficiency further.

A power-saving routine to start today
Check the set temperature
Adjust the current set temperature to 26–28°C and use a fan or circulator together.
Schedule filter cleaning
Register a reminder on your phone to clean the filter every 2 weeks.
Inspect the outdoor-unit environment
Install a shade around the outdoor unit and check for good ventilation.
Adjust your usage pattern
For short outings, don't power off — raise the temperature and let it idle instead.
