A few tips for a really cool summer.

Byline: TEAM SPRINGFIELD By Meredith Clark For The Register-Guard

Some homeowners think of insulation as a winter thing: something that keeps your home snug when the temperature drops. But insulation also keeps out summer's heat, keeping you cool and comfortable.

And if you have air conditioning, insulating your home and sealing cracks can cool down your electric bills. Just be sure the amount of insulation in your home is adequate: Many homes are under- insulated. Check with a professional building contractor for recommendations, or call Springfield Utility Board's Conservation Connection for assistance. SUB offers incentives to help insulate homes with electric heating.

Other things you can do to keep cool air in and hot air out include sealing and insulating air-conditioning ducts (make sure any safety specifications or instructions printed on the ducts are still visible); caulking window and door frames; applying weather stripping; and patching holes in your drywall.

Use drapes as another layer of insulation over your windows during hot weather. Close drapes on south- and west-facing windows during the day to block out the heat. Use awnings that shade summer sun but allow winter light through your windows. Check with us at SUB on how to place your awnings for best effect.

Some other things you can do to stay cool this summer:

Set the thermostat of your air conditioner as high as possible without losing comfort. The less difference between indoor and outdoor temperatures, the lower your cooling bill will be.

Don't set your thermostat at a setting colder than normal when turning it on. It won't cool your home any faster and could run up unnecessary costs.

Don't cool unused rooms.

Boost your cooling system with fans to circulate the cool air.

Turn off the AC and take advantage of natural cooling. Open windows at night for cross ventilation, and use fans to increase the cooling effect. Remember to close the windows by midmorning to keep the cool air in and the hot air out.

Maintain fans and air-conditioners so they run at peak efficiency. This includes cleaning or replacing air filters.

When cooking, use a microwave, electric skillet, toaster oven or slow cooker as much as possible. These appliances use less energy and don't heat your house as much as the oven does. Better yet, go on a picnic!

And finally, check under your house and in your attic for evidence of animal damage. Raccoons, nutria, cats and other animals can get in and shred duct work, creating leaks that result in higher energy bills. Use screens to prevent entry, and if they've already been there, be sure to repair the damage promptly.
