Central air conditioners are designed to work at a fairly constant pace and then turn off when your home reaches the desired temperature. So turning the temperature way down won’t cool it faster, it just means you might end up with a frigid house if you forget to readjust the thermostat once you hit a comfortable temperature, wasting money and energy. There is, however, an exception to this rule. If you have a window unit, you likely have low, medium and high settings. Using the high setting will cool things off faster — just remember to turn it down once your home feels comfortable.
