That’s a lot of power.
A floor fan uses only 100 watts on the highest speed, and ceiling fans use only 15 to 90 watts depending on speed and size..
Does fan mode in AC save electricity?
Here’s a complete list of what you can expect every time you use the fan mode: It conserves energy and power consumption by letting the unit use the fan instead of the compressor – By using the fan alone to provide cool air and ventilation, more power and energy is saved by the unit.
