If you use air-conditioning, set your thermostat as high as comfortably possible in the summer. The less difference between the indoor and outdoor temperatures, the lower your overall cooling bill will be. Don’t set your thermostat at a colder setting than normal when you turn it on. It will not cool your home any faster and could result in excessive cooling and unnecessary expense. If you’re shopping for an air conditioner, look for the Energy Star and EnergyGuide labels. Remember that insulation and sealing air leaks will improve energy performance and comfort in summer by keeping cool air inside. Check out Air Conditioners for more tips.
