It is very true that air conditioners consume the most electricity. The bill for using all the equipment in the house is more than the bill for using the air conditioner. Of course, you have given a great example of how to reduce costs even by using the air conditioner, which is certainly effective. I believe that if you set a timer for one and a half to two hours, it will automatically turn off after the time. The room will also remain cool. Thank you for giving a wonderful article. I wish you success.
