I had purchased hitachi 1.5T Kaze version, the salesperson told me it has the copper coil and comes with inverter technology, (truth is aluminium coil has much better cooling, and with a good brand there isn;t much problem.and it has no inverter technology).
The service given by them is really pathetic, the ac’s cooling effect reduced after 6 months and trying to get in touch with the service people was pretty much pointless. I have literally contacted every person in relation to service. The shop keeper, customer care, area manager.
But getting them to fix the ac was a lost cause.It has been almost 2 months since I had lodged my complaint and no word from them.Spent almost 40k on the ac. Now I regret going for hitachi .The equipment is not trustworthy and the service is just a shame. Please do your research before going for hitachi.
