5 Secrets to Running AC at 24°C and Saving ₹500/Month
Proven tips used by energy auditors — no investment needed for most of these
Set thermostat to 24°C — not 18°C
Save 36%Every 1°C above 18°C saves roughly 6% electricity. 24°C vs 18°C = 36% less energy. Most Indians find 24–26°C perfectly comfortable with a ceiling fan running.
Clean or replace the air filter monthly
Save 15–25%A clogged filter forces the compressor to work 15–25% harder. Takes 10 minutes to remove, rinse, and dry. Zero cost, immediate efficiency gain.
Use Sleep Mode after midnight
Save 8–12%Body temperature drops during sleep. Sleep mode automatically raises the set temperature by 0.5°C/hour over 3 hours. Most inverter ACs have this feature in the remote.
Keep curtains closed during peak sun hours
Save 10–20%Direct sunlight through windows can raise room temperature by 4–6°C, forcing the AC to work overtime. Blackout curtains reduce AC load by 10–20% in top-floor rooms.
Use the AC timer — never leave it running empty
Save up to 30%An AC running in an empty room wastes 100% of energy. Use the 1-hour auto-off timer when leaving, or a Wi-Fi smart controller to cut it remotely.
What is ISEER? Why 2026 5-Star ≠ 2022 5-Star
ISEER (Indian Seasonal Energy Efficiency Ratio) is BEE's benchmark for AC efficiency under Indian climate conditions — not just lab conditions. BEE raises the minimum ISEER threshold for each star level every 2 years. This means a 2022 5-star AC may only qualify as a 3-star or 4-star under 2026 norms.

ISEER, inverter savings, tonnage selection — all answered
Yes — significantly. Every 1°C above 18°C saves roughly 6% on AC electricity consumption. Setting your AC to 24°C instead of 18°C saves approximately 36% on that AC's bill. According to BEE India, the recommended setting is 24°C for both comfort and maximum savings. Pair it with a ceiling fan (BLDC preferred) and 24°C feels as comfortable as 20°C.
