A general misconception which raises electricity billsI may be wrong but ready to get corrected and take the advice in a right spirit.
As per my observations, many people don't understand the difference between using a fan and an air conditioner for getting relief or respite from the summer heat.
There is a basic difference between the two systems. A fan consumes an equal amount of electricity whether operated at a slow speed or at a fast speed and also whether the room is kept closed or open. However, in the case of an air conditioner, it consumes more electricity when set at a lower temperature compared to the situations when it is set at a higher temperature. More important, it guzzles electricity when the room is kept open as the cooled air goes out of the air and puts more load on the air conditioner to work more to further reduce the temperature.
Because of ignorance of this fine difference many first time users, use the air conditioners like fans i.e. they lower the temperature to 18-degree centigrade and keep the room open which results in inflated electricity bills.
What are your observations in this regard?
