I am using ogeneral for past 4 years and the ac is spectacular when it comes to air flow and it chills my whole room within 20-25 min despite the fact that the room is quite big according to the size of my room I would be needing a 2 ton ac but I case of ogeneral 1.5 is just enough.
I know the fact that ogeneral ax are little expensive but I bet you after buying you would surely would not regret on your decision and the fact is that despite such nice air flow the amount of electricity it consumes is not that high in ogeneral the star std term is not present but despite that it is economical yup run it. I hope this will help you in buying a better option.
