One of the biggest mistakes people make when trying to make their homes cooler in the summer or warmer in the winter is moving the thermostat to the highest or coolest setting. Moving the thermostat to an extreme temperature does not reduce the time it takes for your heating or cooling system to change the temperature of your home. You're better off setting the thermostat to the desired temperature so it stops there and won't accidentally keep overheating or overcooling the house.
