In recent days, reports have emerged that the Indian government is moving to standardize air conditioner (AC) temperature settings. Union Housing and Urban Affairs Minister Manohar Lal Khattar has confirmed that going forward, ACs will not be allowed to cool below 20°C. The maximum permissible setting will be capped at 28°C.
This means that in the future, when you purchase a new AC unit, it will come with a preset temperature range—no lower than 20°C and no higher than 28°C. The announcement has sparked widespread discussion across social media and public forums.
Why Has This Rule Been Introduced?
AC industry expert Shailendra Sharma believes this move was long overdue. According to him, the primary objective is energy conservation. Studies show that increasing an AC’s temperature setting by just 1°C can reduce electricity consumption by around 6%. With these new guidelines in place, the government hopes to reduce strain on the power grid and estimates suggest that consumers could collectively save ₹20,000 to ₹30,000 crore in energy bills over the next three years.
AC Compressors and Power Usage
While some AC models technically allow settings as low as 16°C, reaching such temperatures is practically impossible—especially during peak Indian summers when outside temperatures hit 40–45°C. In trying to reach these lower temperatures, the AC’s compressor runs continuously, consuming significantly more energy—up to six times more. This not only leads to inflated electricity bills but also increases pressure on the national power grid during peak demand.
Why 20°C to 28°C Is Considered Ideal
Experts recommend keeping your AC between 20°C and 28°C. Within this range, the compressor switches off periodically instead of running non-stop, which helps reduce energy consumption. Operating your AC at 25–26°C is especially beneficial—it’s energy-efficient, extends the lifespan of the machine, and reduces wear and tear on the compressor.
How India’s New Limits Compare Globally
India isn’t the first country to implement such restrictions. In Japan, for instance, the minimum AC temperature in public spaces during summer is set at 28°C. Singapore mandates a minimum of 25°C in public buildings, while South Korea maintains a 26°C threshold. In that context, setting India’s lower limit at 20°C—especially for its northern states with intense heat—is considered a practical compromise.
Boosting the Lifespan of Your AC
According to Shailendra Sharma, the new rule not only helps reduce energy costs but also enhances the longevity of the air conditioning units. Most appliances degrade faster due to overuse or improper use. By operating an AC at 20°C or higher, the compressor gets time to rest between cycles, reducing stress on the unit and extending its operational life.
The Healthiest Temperature for Human Comfort
For optimal health and comfort, experts recommend maintaining indoor temperatures between 24°C and 26°C. This range aligns with the body’s thermal comfort zone. Running an AC below 20°C may lead to throat irritation, dry skin, muscle stiffness, and even respiratory issues such as infections. A temperature of 24–26°C is not only ideal for sleep but also safe for children and the elderly.
Fewer AC Explosions Expected Under New Rules
Reports of AC explosions during the summer—typically due to overheating compressors—have become increasingly common. With this new temperature cap in place, such incidents are expected to decline. Shailendra Sharma concludes that, no matter how users view the change, it will ultimately benefit both the consumers and their appliances.
