Here are some tips from the U.S. Department of Energy:
- If you use air conditioning, a ceiling fan will allow you to raise the thermostat setting about 4°F with no reduction in comfort.
- Turn off ceiling fans when you leave the room. Remember that fans cool people, not rooms, by creating a wind chill effect.
- Schedule regular maintenance for your cooling equipment.
- Avoid placing lamps or TV sets near your room air-conditioning thermostat. The thermostat senses heat from these appliances, which can cause the air conditioner to run longer than necessary.
- If you live in a climate where it cools off at night, turn off your cooling system and open your windows while sleeping. When you wake in the morning, shut the windows and blinds to capture the cool air.
- Install window coverings to prevent heat gain through your windows.
