Slash energy usage by ushering out moisture

The more humidity inside your home, the more energy your unit uses to chill the air. To give it a helping hand, turn on exhaust fans in the top two moisture-producing areas: the kitchen and bathroom. “Run the range hood fan when cooking and the exhaust in your bathroom during showers and for 10 minutes afterward to reduce moisture,” says Bailes. Then turn them off so you don’t send cool air outside.
