Cooling yourself with a fan vs. an air conditioner is significantly more energy efficient and cheaper. Fans use around 1% of the electricity consumed by air conditioners. You could leave a fan running for 24 hours and still use less energy than 15 minutes of air conditioning.
AC Electricity Usage – A Comparison. Fans undoubtedly use less electricity than an air conditioning unit. In fact, fans use about 99% less energy. However, they both have their place, and it's important to use each appliance correctly to get the best results.
However, in general, whole house fans can save you up to 50-90% on your cooling costs compared to running an air conditioning system.
If u run a split AC for one hour, it would use approx 3.75 units. This is the equivalent of running 12 ceiling fans for an hour.
Since fans only create a wind chill effect and don't lower the actual temperature, there's no need to run the fan where nobody will feel it. While ceiling fans use a fraction of energy compared to AC systems, it's still wasted energy if your fan is running in an empty room.
Thanks to the cooling properties of ceiling fans, you can help to reduce your monthly energy costs. Most central air conditioning systems cost around 43 cents per hour when they're on, which can really add up over time. On the other hand, a ceiling fan typically costs a paltry one penny to run per hour.
Using your ceiling fans and AC unit simultaneously can help save you money on your monthly cooling bill. According to the Department of Energy, if you use air conditioning to cool your home, a ceiling fan will allow you to raise the thermostat setting about 4°F with no reduction in comfort.
Ceiling Fans Are a Healthier Option
This is not a problem with fans – they simply circulate the air around the room – eventually moving it out through open doors and windows. Fresh, healthy air is thus enabled to move freely through your home.
Small Reductions in Fan Speed = Large Savings
A fan's power draw varies with the cube of its operating speed. This relationship means that: Reducing the fan speed by one-half will reduce energy consumed by one-eighth!

The AC uses less energy in fan mode than when cooling. But running the fan all the time can increase the amount of maintenance your HVAC system might need. That's because the filter can clog up sooner and mechanical wear and tear can accelerate.
Fans are cheaper to buy and run compared to air conditioners. For example, running an air conditioner for 8 hours a day during summer could cost about $4 per day, or $120 per month. In contrast, a ceiling fan will only cost around 16 cents per day, or $4.80 per month for the same usage.
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.
Air conditioners are more effective at lowering room temperature and can help maintain a steady, cool environment, which is ideal for very hot or humid nights. However, they consume more energy than fans, leading to higher costs, and their dehumidifying effect can cause dry skin, eyes, and nasal passages.
Running a fan for the entire day will use some electricity, but it's far less than an air conditioning unit running for the same amount of time. Even if you run the fan for 24-hour periods, this would likely account for less than one dollar per day on your electricity bill.
Your air conditioning system is one of the biggest culprits behind skyrocketing electric bills. When your air filter is dirty, refrigerant levels are low, your thermostat is faulty or you lack proper maintenance, your A/C system can end up using a lot more energy than it should.
A more moderate setting like 24°C (75.2°F) can achieve comfort with reduced electricity usage.
One simple way to decrease energy costs is having a higher temperature setting on the thermostat when nobody is home. While you might be tempted to simply turn the AC off, it's actually better to adjust the temperature several degrees higher, by about 7-10 degrees.
Use fans to help the AC
Fans are cheaper to run than air conditioners, and can be used in place of air conditioners or along with them to save money.
Before going to sleep, the air conditioning temperature must be regulated so that it varies between 24ºC - 26ºC in summer and between 15ºC - 17ºC in winter. The environment will be suitable, without exposing your body to sudden changes that may adversely affect it.
It only makes you FEEL cooler because it's moving air over your skin, carrying the heat away from your body. This is the wind chill factor you hear on the Weather Channel so often. So it's doing nothing to lower the temperature in your home, meaning your A/C will run just as long whether the fan is on or not.
Set the thermostat as high as comfortably possible during hot weather. The less difference between the indoor and outdoor temperatures, the lower your cooling bill will be. Keep your house warmer when you aren't home during the day, but cooler when you come home at night.
