DTE Energy Offers Summer Energy-Saving Tips

Monday May 15, 9:05 am ET

DETROIT, May 15 /PRNewswire/ -- Summer is on its way and with it warmer weather. DTE Energy offers the following tips to help customers save money while they're staying cool in the months ahead:

Air conditioning

* Set the air conditioner's thermostat at the highest comfortable setting. When leaving home for more than five hours, raise the thermostat five to 10 degrees. Raising the thermostat just a couple degrees can cut cooling costs by as much as five percent.
* Regular maintenance is important to operating air conditioners efficiently. Check filters at least once a month. Dirty filters cause air conditioners to work harder and use more energy. Many filters can be removed, washed and dried, and reinstalled. Check the owner's manual or contact the manufacturer for more information.
* Keep air conditioning units free of obstructions, inside and out, so air can flow freely. Outdoor units should be free of bushes, and leaf and grass debris. Indoors, move furniture and draperies to prevent blocking window units, vents and air returns.
* Position window air conditioners on the shaded side of the house, away from direct sunlight. Window units generally are not designed to cool more than one room. Close the doors leading to uncooled parts of the house for more efficient cooling.
* In homes with central air conditioning, leave room doors and air registers open so the system can operate effectively.


* Make sure ceiling fan blades rotate clockwise in the summer months to draw cooler air up from the floor.
* A window fan in an apartment or one-story home should be put in a window on the warmest side of the structure; in a two-story home, put it in an upstairs window. Fans draw cooler air inside during the night and circulate air during the day. Make sure draperies are secured for better air circulation and safety. * Prevent heat build-up in the attic by opening attic vents and making sure any lower vents are not blocked. A cooler attic benefits the living area below. An exhaust fan or whole-house fan mounted in the attic will pull hot air out of the attic and living areas and draw cooler air in.
