Just compare all I have done a compassion between non brand and branded.
In Hitachi you will find very wide reach of after sale service .
In machine you will find expandable compressor to 1.75 tr.
And many more things that will keep machine working for atleast 10 years.
Rest on you.
Happy shopping. Happy cooling.
Edit 1-
In above I took only Hitachi
But if you take any good brand like carrier, Bluestar, Daikin, LG , voltas answer will remain same .
Not quality even after sales service which backbone of any AC is not upto that mark that it's should be.
May be next year season mitachi come with better service network .
Because in audio video department they are doing good.
