Use Fans for Low-Cost Cooling
- Fans allow you to raise your thermostat up to four degrees without any reduction in comfort.*
- Make sure ceiling fans rotate counterclockwise in summer.
- Fans cool people, not rooms. Remember to turn fans off when you leave.
Get Your Central Air Conditioner Ready for Summer
- Keep your vents clear. If they’re blocked by rugs or furniture, your air conditioner can’t work efficiently.
- Make sure all your vents are open, free of dust and directing air toward the center of the room.
- Change your filter once a month. A dirty filter makes your system work harder.
- Adjust return registers for summer by closing floor registers and opening ceiling registers. You’ll force hot air out and keep cold air in.
- Close the vents in unoccupied rooms to produce greater airflow in other rooms.
- Tune up your system yearly to improve efficiency and comfort.
Use Window Treatments
- Close blinds, shades and drapes on the sunny side of your house to block out the sun.
Time Your Household Activities to Keep Cool
- Avoid using heat-producing appliances like the oven, stove, dishwasher and clothes dryer during afternoon and early evening when your air conditioner is working hard.
- Avoid taking long, hot showers during the afternoon and early evening hours.
