When the temperature starts to rise, turn the ceiling fans onto the lowest speed. You will be amazed how much the fans will reduce the temperature and how little electricity they use.
If you do have an air conditioner only turn it on if a very hot day is forecast.
The most efficient temperature to set the air conditioner is 19 degrees and the turn on the fans.
Fans work more efficiently with a cross ventilation, with a window partly open on either side of the house. If the house does not have security screens, place a block in the window track for security.
I installed ceiling fans to our house and found I didn’t have to turn the air conditioner on as often.
Moreover, ceiling fans have a long life, so they will soon pay for themselves.
And before anyone asks, no; I do not sell ceiling fans.
