25 cheap ways to keep your house cooler, and bonus #26
 (submitted by Ray M. Chicago)
Simple changes such as moving lamps away from thermostats can save you hundreds of dollars. Here are more money -- and energy -- saving tips.

Sure, go ahead and turn that thermostat up to 80. You'll be sweaty and still shelling out a bundle -- unless you take other steps to make summer heat more bearable and reduce stress on your air conditioner.

Most of these cost little or nothing. Thank the Department of Energy's Energy Savers program, which provides most of these tips (and more) on its own Web site.

Get the most from your air conditioning

  • Open windows and use portable or ceiling fans instead of operating your air conditioner. Even mild air movement of 1 mph can make you feel three or four degrees cooler. Make sure your ceiling fan is turned for summer -- you should feel the air blown downward.

  • Use a fan with your window air conditioner to spread the cool air through your home.

  • Without blocking air flow, shade your outside compressor. Change air filters monthly during the summer.

  • Use a programmable thermostat with your air conditioner to adjust the setting at night or when no one is home.

  • Don't place lamps or TVs near your air conditioning thermostat. The heat from these appliances will cause the air conditioner to run longer.

  • Consider installing a whole house fan or evaporative cooler (a "swamp cooler") if appropriate for your climate. Attics trap fierce amounts of heat; a well-placed and -sized whole-house fan pulls air through open windows on the bottom floors and exhausts it through the roof, lowering the inside temperature and reducing energy use by as much as third compared with an air conditioner. Cost is between $150 and $400. An evaporative cooler pulls air over pads soaked in cold water and uses a quarter the energy of refrigerated air, but they're useful only in low-humidity areas. Cost is $200 to $600.

  • Install white window shades, drapes, or blinds to reflect heat away from the house. Close curtains on south- and west-facing windows during the day.

  • Install awnings on south-facing windows. Because of the angle of the sun, trees, a trellis, or a fence will best shade west-facing windows. Apply sun-control or other reflective films on south-facing windows.

    Landscaping for a cooler house
  • Plant trees or shrubs to shade air conditioning units, but not block the airflow. A unit operating in the shade uses less electricity.

  • Grown on trellises, vines such as ivy or grapevines can shade windows or the whole side of a house.

  • Avoid landscaping with lots of unshaded rock, cement, or asphalt on the south or west sides because it increases the temperature around the house and radiates heat to the house after the sun has set.

  • Deciduous trees planted on the south and west sides will keep your house cool in the summer. Just three trees, properly placed around a house, can save between $100 and $250 annually in cooling and heating costs. Daytime air temperatures can be 3 degrees to 6 degrees cooler in tree-shaded neighborhoods.

    Little things mean a lot
  • Replace incandescent bulbs with compact fluorescents; they produce the same light but use a fifth the energy and heat

  • Air-dry dishes instead of using your dishwasher's drying cycle.

  • Use a microwave oven instead of a conventional electric range or oven.

  • Turn off your computer and monitor when not in use.

  • Plug home electronics, such as TVs and VCRs, into power strips and turn power strips off when equipment is not in use.

  • Lower the thermostat on your hot water heater; 115 is comfortable for most uses.

  • Take showers instead of baths to reduce hot water use.

  • Wash only full loads of dishes and clothes.

    Don't air-condition the whole neighborhood
  • Caulking and weatherstripping will keep cool air in during the summer.

  • If you see holes or separated joints in your ducts, hire a professional to repair them.

  • Add insulation around air conditioning ducts when they are located in unconditioned spaces such as attics, crawl spaces, and garages; do the same for whole-house fans where they open to the exterior or to the attic.

  • Check to see that your fireplace damper is tightly closed.

    Plan ahead
    More costly but effective cooling measures are available as your home undergoes normal upgrades and repairs.

  • A 10-year-old air conditioner, for example, is only half as efficient as a new one. A quick check of your air conditioner's efficiency can help you decide whether to call in a service professional. Use a household thermometer to measure the temperature of the discharge air from the register and the temperature of the return air at the return-air grill. (Keep the thermometer in place for five minutes to get a steady temperature.) The difference should be from 14 to 20 degrees, experts say. An air conditioner that's not cooling to those levels could be low on refrigerant or have leaks. A unit cooling more than 20 degrees could have a severe blockage.

  • Using light shingles on a new roof can cut the amount of heat the house absorbs. Repainting in a light color, especially south- and west-facing exterior areas, helps as well.

  • Upgraded insulation in the attic and double-paned windows all around, complete with tinting to reflect sunlight, are good ideas, too

  • And a bonus--#26  Sometimes it is just too hot to cool the house down. On these days go to the mall and sit or walk around.  Do some people watching. Some of them can be quite interesting. In fact--downright funny. Go to the senior center. Visit a friend with air conditioning. In other words---let someone else cool you today.
