Ideal AC Temperature — Common Questions
Everything you need to know about setting the right AC temperature.
What is the ideal AC temperature in summer?
During summer, the ideal AC temperature is 24–26°C. This keeps the room comfortable while not overworking your AC. For every degree below 24°C, your electricity use increases by about 6–8%.
Is 18°C too cold for an AC room?
18°C is very cold for everyday use and is only recommended for sleeping or exercise rooms. At 18°C, your AC uses significantly more electricity. Most people feel comfortable between 22–26°C.
What AC temperature is best for sleeping?
Research shows that 18–20°C is the ideal sleeping temperature. Our bodies naturally cool down during sleep, and a slightly cooler room helps with deeper, better quality sleep.
How does humidity affect the ideal AC temperature?
High humidity (above 60%) makes the room feel much warmer than the actual temperature. At 60% humidity, a 26°C room can feel like 31°C. In high humidity conditions, lower your AC by 1–2°C or use Dry mode.
What is the WHO recommended room temperature?
The World Health Organization recommends indoor temperatures of at least 18°C for health. For comfort, 20–25°C is the widely accepted range for most adults in normal activity.
