When you’re buying an air conditioner or HVAC system, consider spending a bit more for a programmable thermostat as well. Once it’s installed, consider that programmable thermostat as a cash register. Set it at 68 degrees in the winter and 78 degrees in the summer. When you’re away from home, adjust it 7 to 10 degrees cooler or warmer and you can save 10 percent annually on your energy bill, according to the U.S. Department of Energy.
