As per my opinion, I am using O General ac from year 2008 to till today and that hanging on besides me on wall. Cooling is great, fresh air.
No Problem regarding noisy voice. 1.5 Ton split AC, Buy it and use it. I have seen many reviews that problem with this AC.
Write positive or negative comments or reviews after using it. I know installation of this AC is complicated but OG is best company from the beginning. Everybody should know how they spend their time to test it. After deep consideration, they produce it to the market. Electronic item hai bhai, they may be some defect.
But, I donot understand, why maximum people gave negative points.
