My neighbor has gree 18fith 1 ton, and he is using 5 hours daily, and i m using dawlance 1.5 ton , and my use is continuous 11 hours a day, my electricity bill after a month was 4600 and my neighbor had 5500. So the reality is gree is a big brand , no doubt, but 18 fith is old model, try gree fairy series, 115000 price but t1 compressor, it takes 0.9 amps on 28 degrees, good for Karachi, but not for faisal abad, get the dawlance and if not satisfied, sale me the same unit
