The debate over whether to turn off the air conditioner when leaving home or keep it running continues. Experts say there is no one-size-fits-all answer. This was reported by Qazaqyia.kz citing Associated Press.
According to the Associated Press, which interviewed three experts, setting the thermostat a few degrees higher while away is generally the best way to balance energy efficiency against comfort and humidity.
Turning off an AC unit for several hours and turning it back on can save money and energy compared to continuously running it, but can lead to mold problems in humid environments as well as wear and tear that may cause more frequent repairs. The equation varies depending on factors including comfort level, AC unit type, and building insulation.
According to the U.S. Department of Energy, adjusting your thermostat by 7-10 degrees Fahrenheit (4-6 degrees Celsius) for eight hours a day can save up to 10% a year on heating and cooling.
Elizabeth Hewitt, professor at Stony Brook University, said: "If you're gone for like 15 minutes to go to the grocery store, you don't get any gain by turning off your AC. But if you're going for your work day, say for eight hours or so, you'll almost always save more energy and money by turning things off."
In some climates, however, turning off the AC might not be feasible, so residents should consider alternative methods.
