Regular maintenance will help to ensure that your air conditioner operates efficiently. Clean air conditioners filter once in every two weeks.
Close your doors, windows and curtains when air conditioner is running inside the room.
Use kitchen, bath and other ventilating fans wisely. These fans can pull out cooled air from the room. Turns off ventilating fans as soon as they have done the job.
Replace old air conditioning systems with energy efficient air conditioning equipment.
Set thermostat at 76 ºF ( 24ºC ) or above when the house is occupied during the day and few degrees higher at night.
