Why is 24°C Considered the Ideal AC Temperature?

Here’s why 24°C is the best AC setting:

• It balances comfort and energy savings

• Helps maintain a healthy indoor environment

• Reduces the risk of catching a cold or fatigue

• It aligns with the human body’s normal temperature

• Cuts down electricity bills significantly

Top 10 Benefits of Setting Your AC at 24°C

1. Saves Electricity

The biggest benefit of setting your AC to 24°C is lower electricity consumption. Every degree lower increases energy use by 6-8%.

2. Reduces Monthly Electricity Bills

Less power consumption means more savings. Over time, setting the AC to 24°C can reduce your electricity bill by up to 15-20%.

3. Comfortable for the Human Body

24°C is close to the body’s comfort zone, avoiding extreme cooling and health issues like cold, cough, and body pain.

4. Environmentally Friendly

Lower power consumption = reduced carbon emissions. It’s a small step toward an energy-efficient and sustainable planet.

5. Improves Sleep Quality

Setting the AC to a moderate temperature like 24°C ensures better sleep, especially during hot and humid nights.

6. Increases AC Lifespan

Avoiding overcooling reduces load on the compressor, which leads to less wear and tear, thus extending your AC's life.

7. Reduces Risk of Illness

Overcooling can cause sore throat, dry skin, and respiratory issues. A moderate temperature helps maintain good indoor air health.

8. Better AC Performance

Modern ACs work more efficiently when set between 24°C to 26°C, especially inverter ACs.

9. Safer for Children and Elderly

Extreme cooling may affect babies and seniors. A 24°C setting is safe and balanced for all age groups.

10. Compliance with Government Standards

Following the 24°C rule aligns with government advisories, making your home energy-smart and policy compliant.

What Happens if You Set the AC Below 24°C?

• Higher electricity bills

• Risk of health issues like dry throat and cold

• Faster wear-out of AC parts

• Uneven room temperature

• More environmental impact
