Keeping your home comfortable can cost plenty, especially in the hot Texas weather. Try these tested tips to save money and stay comfortable.

• Set the air conditioning thermostat at 78 degrees or higher. Save more by raising the setting to 85 degrees when you're out for at least four hours. Consider installing a programmable thermostat, and set it to cool the house before you get there.
• Use ceiling fans or portables. Moving air feels four to six degrees cooler.
• Block the sun. Save on cooling costs by closing drapes during the day or adding energy-efficient windows. Solar screens on west-facing windows also keep the sun at bay.
• Ventilate the attic. Proper ventilation reduces temperature and prevents moisture buildup, so the air conditioner does not have to work as hard.
• Turn off or replace lights. Most energy from incandescent bulbs becomes heat. Compact fluorescent bulbs use 75 to 80 percent less energy and produce less heat.
• Zap it. Use the microwave rather than the oven if you do cook. Consider chilled foods, too.
• Add shade. Add trees and shrubs on the east, west and south sides of your home to cut cooling costs. Shade air conditioning units, but leave room for air to flow. Don't plant near power lines.
• Stop leaks into and out of the home. Check your ducts for leaks, and seal them with masking tape if needed. Caulk and weather-strip windows, doors and pipe clearances.
• Let air flow. Clean or replace air filters regularly for efficient air exchange.
