6 Ways to Cut Your Summer AC Bill
Combined savings potential: ₹2,000–4,000/month in peak summer
Set 24–26°C, not 18°C
₹700–1,400/monthEvery degree above 18°C saves 6%. Going from 18°C to 24°C saves 36% instantly. At 44°C outside, 24°C inside is still a 20°C difference — very comfortable.
Use ceiling fan alongside AC
₹300–600/monthA ceiling fan circulates cool air, making 26°C feel like 23°C. This lets you raise AC temperature by 2°C, saving 12–18% on your bill.
Service AC before April
₹400–800/monthA March service (clean coils, check gas, clean filter) ensures peak efficiency during the most expensive months. Dirty coils increase consumption by 15–25%.
Close curtains 10AM–4PM
₹200–500/monthBlackout curtains block 70–80% of solar heat gain through windows. This reduces the AC load significantly during peak heat hours.
Pre-cool before peak heat
₹300–600/monthCool your room to 22°C before 11AM, then raise to 26°C. Thermal mass (walls, furniture) keeps the room cool longer, reducing AC run time.
Use sleep mode at night
₹400–700/monthSleep mode gradually raises temperature as you sleep (body temperature drops). Saves 20–30% on overnight AC use without affecting sleep quality.
