5. Raise the Thermostat During the Day in the Summer, Lower at Night in the Winter.
After homeowners have ensured that their cooling systems are in top working order, they will want to use them as little as possible. This time would be during the day when most people are at work in the summer. You can set the thermostat higher when you are not in the house and lower it when you come home at night. Do the opposite in the winter. This tactic will save as much as $180 in each energy bill.
