Why You Shouldn’t Set Your Air Conditioner to 26°C — A Mistake I Made for Decades Until an AC Technician Pointed It Out
For most people, 26°C seems like the perfect indoor temperature—not too hot, not too cold, just cool and comfortable. However, it turns out that setting your air conditioner to 26°C might not be the best idea.
When using an air conditioner, many of us aim for a temperature that balances comfort and energy efficiency. But few realize that there are specific tips and tricks for setting the ideal AC temperature. Recently, a common question has drawn attention: Why shouldn't you set your air conditioner to 26°C? Thanks to a reminder from a seasoned AC technician, I learned that I had been making this mistake for decades.
Why Do So Many People Choose 26°C?
Most people consider 26°C to be a moderate, pleasant temperature—not too cold, not too warm, and easy to tolerate. But HVAC experts point out that setting the temperature this high can actually reduce cooling efficiency, increase energy usage, and even impact your health. Therefore, choosing the right temperature is key to maintaining comfort while conserving energy.
What Do Experts Recommend?
Air conditioning technicians often recommend setting the temperature below 25°C, with 24°C being ideal in many cases. At this range, the air conditioner cools more efficiently, performs better, and still saves on electricity. According to energy data, lowering the temperature by just 1°C can reduce energy consumption by 5–10%, which can significantly impact your electricity bill—especially if you run the AC regularly.
More Than Just Energy Savings
The right AC setting isn’t only about efficiency—it also affects your health. During hot days, a properly cooled indoor environment helps prevent heatstroke, dehydration, and thermal stress. However, if the temperature is set too high, humidity levels indoors may rise, creating a breeding ground for bacteria and mold. This can worsen indoor air quality and potentially lead to respiratory issues. So, choosing a proper temperature is not just about staying cool—it’s also about staying healthy.
In Conclusion
To stay comfortable, save on electricity, and protect your health, setting your air conditioner at the right temperature is essential. Experts advise aiming for around 24°C for the best balance of comfort, efficiency, and well-being. So next time you reach for the remote, remember this simple but important tip—your body, wallet, and air quality will thank you.
