With unseasonably cold temperatures this weekend, Southern California Gas Co. officials Friday offered several tips to keep comfortable and save money: The best way to keep winter gas bills lower is to conserve energy. When using the home furnace, lower the thermostat three to five degrees and turn it off when not at home. This can help save up to 20 percent of heating costs. Check the furnace filter monthly and clean or replace it to save up to 2percent on heating costs. Caulk and weatherstrip drafty doors and windows to save up to 5percent on heating costs. Use an extra blanket and turn down the thermostat at night as the weather turns cooler. Take shorter, cooler showers. For a family of four, a seven-minute shower a day per person could save about $30 on the monthly gas bill. Use cold or cool water when washing clothes to save up to 10 percent on hot-water costs. Fix leaky faucets to prevent hot water from being wasted. Run the dishwasher only when full. Have air ducts tested for leaks and seal any leaks to save up to 20 percent on heating costs. For more information on conservation and simple home-improvement tips, as well as energy efficiency rebates, call the Gas Co. at (800) 427-2200, or visit its Web site at www.socalgas.com.
