AC at 24°C vs 18°C — The Real Cost Difference

There's a viral myth that lower AC temperatures cool a room faster. They don't. The compressor runs at the same speed regardless of setpoint — what changes is how long it runs to reach the target.

Take a 1.5-ton 3-star AC running 8 hours/day at ₹8/unit. At 24°C the compressor cycles ~50% of the time, consuming roughly 6 units/day → ₹1,440/month. At 18°C it runs almost continuously, consuming roughly 9.5 units/day → ₹2,280/month.

That's a difference of ₹840 every month — ₹10,000+ per year — for the exact same number of hours of use. Pair 24°C with a ceiling fan and the perceived temperature drops another 2–3°C without touching the thermostat.

Bottom line: 24°C is the comfort-vs-cost sweet spot endorsed by BEE. Combine it with SaveMyBill and you save twice — once on consumption and again on every payment.
