Since ceiling fans don't actually lower the temperature of the air inside your home, and a room has to be occupied to feel its effects, there's no reason to leave your ceiling fan on 24/7. In fact, it simply wastes electricity and adds unnecessary wear and tear to your fan motor.
conclusion. Ceiling fans are designed for prolonged use and can run 24/7 without much trouble. However, just like with any home appliance, it's not totally safe to leave them running unattended. For lower energy bills and peace of mind, it's better to invest in energy-efficient DC fans that include a timer setting.
Since it cannot heat or cool the air in the room, running the fan for an extended period of time is not applicable. Continuous working will heat up the motor and increase the temperature of the room even more. The primary purpose of a fan is to enhance the efficiency of an air conditioner.
If you leave the average fan on 24/7, never turning it off, it'll use about $6-9 per month of electricity.
Unless you are physically in the room while the fan is on, it's not doing any good. If you're not there to benefit from the ceiling fan's air circulation, then you're just using more electricity. If your air conditioner isn't operating efficiently, then your ceiling fan isn't doing it any favors.

Ceiling fans come in a variety of wattages, but a standard 48-inch model uses about 75 watts per hour on average. This would cost you about $0.01 per hour, or $6 per month if you leave your ceiling fan on 24/7 all month.
The Cost of Running a Ceiling Fan for 24 Hours
Now, to convert this to kilowatt-hours (kWh), divide by 1000, giving you 1.8 kWh. If your electricity rate is ₹5 per unit (1 kWh), running the ceiling fan for 24 hours will cost you ₹9 (1.8 kWh x ₹5/unit).
A standard ceiling fan tends to last up to 10 years, but this will all depend on the quality of it and how you look after it. Factors will include how often you use it and how often you don't use it.

Moving air creates a wind chill effect that cools your body. Ceiling fans are a great option to take the edge off hot summer days and use less energy than air conditioning units. Ceiling fans make a room feel cooler for its occupants by circulating warm air up and cool air down.
Lifespan: On average, a standard ceiling fan can last anywhere from 7 to 10 years. However, factors like usage frequency, motor quality, and overall care can significantly impact this lifespan. Signs of Trouble: Watch out for wobbling blades, unusual noises, or sluggish fan speeds.

Heating and cooling: 45-50%
The largest electricity consumer in the average household is your heating and cooling appliance. By a long shot. Central air conditioners and heaters use tons of energy in order to keep your home set to the right temperature.
Generally, TVs use between 50 to 200 watts (W) of electricity, depending on the model. Most TVs use less than one amp and connect to a 120-volt outlet. Older TVs that use technology such as Plasma and CRT are much less efficient compared to newer LED and LCD TVs.
"Besides the risk of an electrical fire and health complications, when you leave the electric fan on for too long, you're also running the risk of burning its motor. Even though that shouldn't happen for a while if the fan isn't a cheap model, it'd still be good to keep it running with caution," explains David.
Overheating is another issue to watch out for. If your ceiling fan gets too hot to touch, it's a clear sign that it's working harder than it should be, which could be due to a variety of electrical issues.
System stress: Your air conditioner unit needs time to take a break. If it's running all the time, it can be damaging to the system and lead to the need for a costly replacement. Energy bills: The cost to run your AC 24/7 can be high.
As long as your fan is clean, sleeping with a fan on generally doesn't cause serious health problems. But fans circulate air that may dry your nose and throat, and trigger other uncomfortable symptoms.
The Disadvantages of Ceiling Fans
