Yes, as long as your ceiling fan is set to spin in the right direction, it can increase air conditioning efficiency and help reduce how much you spend on your monthly electric bills. Depending on the time of year, you should set your ceiling fan direction to clockwise or counterclockwise.
A ceiling fan can actually help lower your electricity bill. By circulating air in a room, a ceiling fan can make a space feel cooler, so you may not need to run your air conditioner as often. That can lead to lower electricity bills in the summertime.
The Givoni or Woods diagrams show a direct relationship between air speed and the drop in temperature felt by users of the room. In this case, a ceiling fan will consume between 20 and 50 watts (still a long way from the consumption of an air-conditioning system (800 to 1500 watts, i.e. 30 to 40 times more).
Ceiling fans use 0.6 kWh to 0.9 kWh per day in electricity and are an energy-efficient way to cool your home, typically costing less than 20 cents a day to run the fan all day long. Central air conditioning is a far more expensive cooling option, costing nearly 50 times more to run than a ceiling fan.
Instead of running your AC at 72 degrees, a fan allows you to set your thermostat to 78, yet still feel as if it is about six degrees cooler. A fan costs pennies per day to operate versus dollars per day for the AC.
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.
Lower Cooling 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.
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.
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.
Some people fear that a ceiling fan will overheat and catch fire if left ceiling fan running overnight; however, these fears are unreasonable. Ceiling fans are designed and manufactured to run for hours on end, and if you invest your money in a reputable brand, you shouldn't have any fears.
Verify: No. Leaving a ceiling fan on all day long will not save you money on your electric bill.
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.
The short answer is that it depends on your kind of television and how big it is. It's also important to consider how long you're leaving your TV on each day. The more hours it's on, the more electricity it's using.
– An average small bathroom fan, when running continuously for 24 hours, typically consumes around 5 to 10 watts of electricity. – To put this in perspective, a standard incandescent light bulb (60 watts) consumes roughly 5 times more energy per hour than a small bathroom fan.
What costs the most on your electric bill? Heating and cooling are by far the greatest energy users in the home, making up around 40% of your electric bill. Other big users are washers, dryers, ovens, and stoves. Electronic devices like laptops and TVs are usually pretty cheap to run, but of course, it can all add up.
A home refrigerator's power consumption is typically between 300 to 800 watts of electricity, or between 3 and 6 amps and about 120 volts. Importantly, refrigerators generally have a much lower "running" wattage than their stated average wattage – this is because they cycle on and off throughout the day.
This calculation shows that running a standard ceiling fan for 6 hours a day would cost you approximately 5 cents per day or about $18.25 per year. This figure is significantly lower compared to air conditioners, which can consume up to 3,500 watts and cost up to $1.20 for the same 6-hour period.
Here's a question we hear often from those who brave the humid Atlanta weather: “Should I run my air conditioner with a ceiling fan?” Answer: You can— and should— run your A/C and ceiling fan together. Doing so can help lower your cooling costs each month, but only if you're using them right. Here's what we mean.
Be More Efficient
You will find that your electric heat, air conditioner and water heater will typically make up the greatest percentage of your electric bill, so these are the areas in which you may want to concentrate your energy management efforts.
