All homeowners can benefit from thoughtful energy improvements. The most fumble-fingered can complete most of them with little effort, a few hours and a bit of money for materials.
Heck, you’ll probably even qualify for a tax credit.
Simple steps - like changing light bulbs or replacing the filter in your air conditioner - can trim your electric bill by 5 percent. Set your thermostat at 78 or higher this summer; every degree below 78 can raise your bill 5 percent to 7 percent.
Only do full loads of laundry and dishes. Turn off lights and fans when you leave a room. Fans only make you feel cooler. They do nothing to lower the temperature.
Some tips are slightly more ambitious. The U.S. Department of Energy and the Alliance to Save Energy have offered consumers advice on smart energy practices this summer:
• A well-maintained cooling system will run more efficiently, use less energy, and lower energy bills, so clean or replace AC filters monthly or as needed. Also, keep both outdoor and indoor air conditioner coils clean. Dirt build-up on the indoor coil is the single most common cause of poor operating efficiency.
• Check air conditioning ducts. If you feel leaks between sections, or where the ducts connect with the air handler, seal them with metal tape and a coating of mastic.
• Plug energy leaks by caulking and weather stripping all seams, cracks and openings to the outside. You can save 10 percent or more on energy bills by reducing air leaks.
• Sufficient insulation can increase your comfort and reduce your cooling costs up to 30 percent. Start with the attic - which can reach temperatures of 115 degrees - followed by exterior and basement walls, floors, and crawl spaces. Insulate and seal attic air ducts, too.
• When possible, delay heat-producing activities such as dish washing until the evening. Close curtains during the day, and install awnings on south-facing windows. Plant shade trees or vines.
• During the cooling season, keep your house closed tight in the daytime to keep unwanted heat and humidity out. If practical, ventilate at night either naturally or with fans.
• Avoid running a dehumidifier at the same time as the AC. The dehumidifier will increase the cooling load and force the air conditioner to work harder.
• Shift energy-intensive tasks such as laundry and dish washing to off-peak energy demand hours to increase electricity reliability during heat waves; do full loads when you run washers, dryers, and dishwashers.
• Switch to cold water washing of laundry in top-loading, energy-inefficient washing machines to save energy and up to $63 a year-detergents formulated for cold water get clothes just as clean; clean the lint filter in your dryer after every load.
• Keep lamps or TVs away from the air conditioner thermostat. The heat they generate will cause your air conditioner to run longer, running up bills unnecessarily.
• Save up to 10 percent a year with a programmable thermostat that automatically adjusts the temperature by 10 to 15 percent for the hours that the house is unoccupied.
• Ceiling and other fans provide additional cooling and better circulation so you can raise the thermostat and cut down on air conditioning costs. Energy Star-certified ceiling fans do even better, moving air up to 20 percent more efficiently than conventional models, and those that include energy efficient compact fluorescent light bulbs (CFLs) are up to 50 percent more efficient than those with incandescent lighting. The CFLs last six to 10 times longer than traditional lighting and generate 70 percent less heat.
