It is tempting to show down your air conditioning to its lowest temperature as soon as you enter the space, thinking space will cool faster, but actually, it doesn't help much. Keep your air conditioners running at the optimal temperature, preferably at 24 deg C as this may assist you to save on your electricity bill. The lesser the difference between in temperatures inside the house and out of doors, the less money you'll find yourself spending on operating costs for your air conditioning.
