How do ACs and Fans Compare in Power Consumption

The article compares AC vs ceiling fan electricity cost, showing that ceiling fans use significantly less power, while ACs provide actual cooling and dehumidification.

• A 70–75 W standard ceiling fan costs about Rs. 189/month at 12 hours daily and Rs. 7 per unit.
• A 28–35 W BLDC fan can cost around Rs. 88/month.
• A 1.5-ton 5-star inverter AC can cost around Rs. 1,512–Rs. 1,848/month at 8 hours daily.
• A 1.5-ton 3-star inverter AC can cost around Rs. 2,016–Rs. 2,520/month.
• A ceiling fan is recommended below around 32°C, while an AC becomes more useful above 38°C.
• Setting the AC to 24°C and using a ceiling fan alongside it can reduce AC electricity consumption by around 10%–12%.

You can also buy a new AC on Easy EMIs at over 1.5 lakh partner stores across 4,000 cities, including Reliance Digital, Croma, and Vijay Sales. 
 

The ac vs fan electricity cost varies significantly because an AC requires much more power than a ceiling fan. A 28–35 W BLDC fan can cost around Rs. 88/month, while a 70–75 W standard ceiling fan costs about Rs. 189/month. In comparison, a 1.5-ton 5-star inverter AC can cost approximately Rs. 1,512–1,848/month, while a 1.5-ton 3-star inverter AC may cost Rs. 2,016–2,520/month, based on the usage assumptions in the comparison. The ceiling fan vs AC power consumption difference is therefore substantial. A fan is suitable when air movement is sufficient, while an AC is more useful when you need actual temperature reduction and dehumidification. Using a fan with an AC can also help reduce cooling energy use.

If you want to replace your AC, visit any of Bajaj Finance's 1.5 lakh partner stores — like Vijay Sales, Croma, Reliance Digital, and more — across 4,000 cities, including Tier 2 cities like Jaipur, Lucknow, Kochi, Bhopal, and more in India. Choose your preferred model, then use the Bajaj Finance Insta EMI Card or Bajaj Finance Easy EMI Loan to finance it. Convert the cost into Easy EMIs that suit your monthly budget and enjoy zero down payment on select models — take it home without any upfront payment. Check your loan eligibility online in minutes so you know exactly what you can get before you step into the store. 

Yes. An AC can cost around 8–10 times more to run than a ceiling fan, although the actual difference depends on appliance rating, usage hours and electricity tariff.

• A 28–35 W BLDC fan can cost around Rs. 88/month, while a standard 70–75 W fan costs about Rs. 189/month.
• A 1.5-ton 5-star inverter AC can cost around Rs. 1,512–1,848/month under the stated usage assumptions.
• A 1.5-ton 3-star AC can cost approximately Rs. 2,016–2,520/month.

• Using a fan whenever conditions allow can potentially save around Rs. 8,000–16,000 annually.

  
  

However, a fan cannot replace an AC when temperatures exceed around 36°C or humidity is high, as it does not actually lower room temperature.

A standard ceiling fan uses 70–75 W, while a 1.5-ton 5-star inverter AC uses around 900–1,100 W, consuming roughly 13–15 times more electricity per hour. This makes ceiling fans the lower-power option for everyday air circulation, while ACs provide actual temperature reduction and dehumidification.

A ceiling fan is the more electricity-efficient choice for moderate weather, using just 70–75 W compared with 900–1,100 W for a 1.5-ton 5-star inverter AC. However, an AC is more suitable when you need actual temperature reduction and dehumidification, particularly during hot or humid conditions.

Use a ceiling fan when the outdoor temperature is below 32°C; switch to an AC above 38°C when fan-circulated air is too warm to provide sufficient comfort. The right choice also depends on humidity, room conditions and whether you need actual temperature reduction.

A ceiling fan is ideal for mild weather below 32°C, while an AC becomes more useful above 38°C or when humidity makes fan-only cooling uncomfortable. Using a fan whenever conditions allow can reduce electricity consumption, while the AC provides stronger temperature control when required.

Running an AC efficiently can cut monthly electricity consumption by 20% to 40% without any reduction in comfort. Here are the most effective daily habits to adopt.

• Set the thermostat to 24 degree Celsius — every degree below 24 degree Celsius increases electricity consumption by approximately 6%; 24 degree Celsius delivers comfortable cooling at significantly lower compressor load.
• Run the ceiling fan alongside the AC — this allows the AC thermostat to be raised by 2 degree Celsius without any perceptible reduction in comfort, reducing electricity consumption by approximately 10% to 12% daily.
• Use Sleep mode overnight — Sleep mode raises the temperature by 0.5 degree Celsius to 1 degree Celsius per hour after activation, reducing unnecessary compressor runtime during the cooler early morning hours.
• Clean the air filter every two weeks — a clogged filter reduces airflow efficiency by up to 20%, forcing the compressor to run longer to achieve the same set temperature, directly increasing electricity consumption.

• Set a timer to switch off the AC after two to three hours of sleep — room temperature drops naturally after midnight; the timer prevents the AC from running unnecessarily through the coolest part of the night.

  
  

Using a 24°C thermostat, a ceiling fan, clean filters and closed doors can help reduce unnecessary AC power use while maintaining comfortable cooling and potentially lowering your monthly electricity bill.
