I will never ever make the mistake of buying a hitachi product ever in my life again.
I purchased 2AC 3 weeks ago and it is not yet completely installed because the indore unit of one of the AC is faulty and is not yet replaced. And the remote of the other one is faulty.
The hitachi customer response is by far the most irresponsible one I have ever encountered for a product company. Two requests for installation were randomly cancelled by the local service center without even starting the installation. The 3rd request was answared and installation exicutives came.
