Save energy, but still stay cool. ECO mode uses less compressor capacity compared to Normal mode, which reduces energy consumption*. It lets you cool more efficiently when it’s not too hot outside or just save energy and money at any time, so you don’t have to worry about the electricity bills.
* Tested on the AR07T9170HA3 compared with Samsung conventional models, measuring the accumulated power consumption of Fast Cooling mode vs. ECO mode.
