Finally after a lot of research and enquiry I have found General 1.5T 5 star CET-B series AC from authorized seller. I found his contact from General website.
My requirement today is for a rented house not exposed to direct sunlight in any direction nor the rooftop. But cant say the same in future as i might move.
I have finalized the product for 65K+500 shipping. 5 year PCB warranty and 10 year compressor warranty. For me money is not an issue main thing I am looking at is the long term reliability and decent service.
Now when researching about the General most on reddit agree that General's CETB series is solid AC but also few on other platforms says General has fake products in its name, now this made me concern.
Also looked at Mitsubishi HNI n electric but no stock with 1.5T 5*, even other brand's reliable models are out of stock. So I found only this.
Please share your honest opinions. Everyone has good and bad experience on almost all the brands. So i have to take a tough call.
Edit - He said installation is done by company and upto 9 feet of copper pipe and installation is free.
