The cost of air conditioning It takes significantly more energy for an air conditioner to move heat around than it takes a fan to blow air onto your skin. As a result, parking yourself in front of a fan is significantly more energy efficient. Fans use around 1% of the electricity consumed by air conditioners.
Does AC consume more electricity or fan?
Central Air Conditioning (AC) uses around 3500 watts of electricity per day, an AC window unit uses between 600 and 1500 watts and a ceiling fan uses between 30 and 50 watts, so it’s quite a savings! However, there are a few caveats involved in saving the maximum amount of energy and still staying cool.
How much power does a fan use compared to air conditioning?
Whereas a 2.5-ton central air conditioner uses about 3,500 watts and a window A/C unit typically uses between 500 to 1,500 watts, a ceiling fan uses only 15 to 95 watts depending on its size and speed. That’s a whopping 99% decrease in cooling costs when you use ceiling fans instead of air conditioners.
Does reducing fan speed Save electricity AC?
Keeping the ceiling fan running, you can increase the thermostat of the AC by 2 to 4°C without disturbing the thermal comfort. At a higher thermostat setting, air conditioners consume less electricity.

- Fans are much more cost-effective in terms of energy use.
Which AC mode is best for saving electricity?
