Cooling Your Home at 45°C: What Costs Less: AC, Cooler or Fan?
Different cooling devices consume vastly different amounts of electricity. A ceiling fan typically uses around 75 watts, an air cooler about 150 watts, while a 1.5-ton air conditioner consumes roughly 1050 watts per hour. This difference directly impacts electricity bills, especially during peak summer usage.
Monthly electricity cost comparison
When used for about 8 hours daily at an average electricity rate, the cost difference becomes stark. A fan may cost roughly ₹120-₹130 per month and an air cooler around ₹250, while an AC can go up to ₹1,700 or more. In simple terms, a fan is nearly 10-11 times cheaper than an AC, and a cooler is about 6-7 times cheaper.
Cooling performance in extreme heat
Cost isn’t the only factor, performance matters. Fans only circulate air and offer limited relief once temperatures cross 35°C. Air coolers can reduce temperatures by 5-10°C in dry climates, making them a practical middle-ground solution. However, during extreme heat or in humid conditions, air conditioners remain the most reliable option for consistent cooling.
