As the summer heat intensifies, many people resort to setting their air conditioners to 23–24 degrees Celsius, aiming for a quick cooldown. However, this practice not only leads to soaring electricity bills but may also adversely affect your health, especially during the night. Surprisingly, even setting your AC to 26 or 28 degrees Celsius – which seems reasonable – could still be detrimental if you overlook a crucial factor: using electric fans before turning on the air conditioner.

Why Should You Turn on the Fan Before the AC?
Energy experts emphasize that using a desk or ceiling fan before switching on the air conditioner enhances air circulation and ventilation. The breeze from the fan accelerates sweat evaporation from your skin, aiding your body in cooling down faster, providing a refreshing feel even before the room temperature significantly drops.
Instead of immediately setting your AC to a low temperature, consider running the fan for about 5–10 minutes to acclimatize your body to the circulating air. Subsequently, when you turn on the AC at 27–28 degrees Celsius, you’ll still feel as comfortable as if it were set at 23–24 degrees, but with significantly reduced electricity consumption.
A Dual Benefit: Comfort and Energy Savings
Research reveals that by merely increasing the AC temperature from 24 to 26.5 degrees Celsius and utilizing a fan simultaneously, you can save up to 30% on your electricity usage. In contrast, a typical electric fan consumes only about 3% of the energy used by an air conditioner, highlighting the substantial difference in efficiency when employing both devices.
Additionally, operating the air conditioner at higher temperatures eases the burden on the compressor, reducing wear and tear and prolonging its lifespan. This not only saves on electricity costs but also diminishes long-term repair and replacement expenses.

Adopting the simple habit of using an electric fan before turning on the air conditioner and maintaining a reasonable temperature setting, such as 27–28 degrees Celsius, ensures a comfortable environment while preserving your health and finances.
Start implementing this adjusted approach to air conditioning today for a more enjoyable living space without the worry of monthly electricity costs.
Why You Should Avoid Setting Your AC to 26 Degrees Celsius at Night
“Turning on the air conditioner at 26 degrees Celsius while sleeping can be tempting, but experts advise against it. This seemingly harmless habit may have negative consequences for your health and well-being, and understanding the reasons behind this recommendation is crucial for a good night’s rest.”
