I switched my AC to 26°C for a month — my electricity bill dropped more than I expected

ACs are one of the biggest contributors to household electricity bills in India. With temperatures soaring above 45°C and high humidity, staying comfortable in summer, and even monsoon months, becomes a challenge. Like many people, I assumed that lowering AC's temperature would make my room cool faster and keep it comfortable. But after hearing experts and reading about the new BEE norms repeatedly recommending the 26°C setting as the ideal balance between cooling and energy efficiency, I decided to test out their advice.

What I did was that I kept my inverter AC fixed at 26°C instead of my usual 20–22°C and tracked how it affected the room's cooling performance, my comfort and my electricity bill, for a period of a month. Interestingly enough, the results were shocking and more noticeable than I expected. While my room remained comfortably cool for daily work and sleeping, the AC consumed significantly less energy compared to when I ran it between 20–22°C. Here's the calculation for that will help you understand my findings better.

Cooling at 20°C vs 24°C vs 26°C: The math behind it

Now, that we have established how 26°C is the ideal temperature for your AC, here are the top 1.5-Ton ACs that you can buy in India. But before that, let's understand what 26°C rule is.

What is 26°C rule?

The 26°C AC rule is an energy-saving guideline promoted by the Bureau of Energy Efficiency (BEE). This guideline advises manufacturers to keep the default setting of ACs at 24°C and to show labels indicating that the optimum temperature setting for the benefits of consumers both from financial and their health points of view stands in the range of 24-26°C.
