Experts Advise 78°F AC Setting Across Midwest, Northeast Amid Heat Wave

As a heat wave grips much of the United States, including Michigan, Maine, and the Northeast, experts recommend setting air conditioners to 78 degrees Fahrenheit during the day to balance comfort and energy efficiency. The U.S. Environmental Protection Agency's Energy Star program and the Department of Energy advise raising the thermostat 7 to 10 degrees when away from home and approximately 4 degrees higher during sleeping hours to save on energy costs. Despite these recommendations, surveys show most Americans prefer cooler settings, typically around 71 to 72 degrees, which can increase electricity bills during peak summer months. Other energy-saving tips include using fans to circulate air, closing window curtains to block heat, and minimizing the use of heat-generating appliances. When away on short vacations, experts suggest keeping the AC on at a higher temperature to prevent mold, mildew, and discomfort for pets, as turning it off entirely may lead to higher costs when cooling down the home again. Overall, the challenge remains finding a balance between staying cool and managing rising energy expenses amid record-breaking temperatures.
