I have been using godrej air conditioner both split and window and I would say godrej AC are by far the best AC’s in India as of now. Best in terms of pricing and in quality.
It has been five years now and no problems faced. I wont comment on any other AC but My only suggestion would be if you need a problem free air conditioning then it has to be godrej.
Truly an Indian brand which lives up to its brand value and faith.
