Top critical review

Purchasing AC from this series - 'MERAI' Inverter AC would look very lucrative given the price, but you might end up cursing yourself for the most important aspect of the IDU - Fan Noise. All Hitachi Split AC models except the higher end ones have this same noise rating.
Hitchi Personnel when confronted with this fact say that this noise is normal. Strangely, while other Brands are focussed in making Split AC esp. Indoor unit even less noisier, Hitachi product innovation seems to be moving in an opposite direction.
This new series of Inverter ACs from Hitachi - 'MERAI' has high rpm for the Indoor Unit Fan. Which results in a very high ambient operational noise. To give an actual picture - the noise it generates at LOW fan speed is equivalent to or higher than what ACs of other Brand produce at High fan speed. This is for a split AC which are suppose to make negligible noise. Ambient Noise levels at Fan Speed - 'Low' is 38db. A cursory look at noise levels of competitors will reveal that they make this noise at High fan speed. Imagine trying to sleep with the AC making so much noise at lowest fan speed. Noise is so high, that it acts as a disruption to a conversation in normal audible volume as well as affects sound sleep.
I purchased, repented and had to fight tooth and nail with them to accept this design folly and thus a return. Which they finally did in a tight lipped manner. It's a pain and close to impossible to escalate matters at Hitachi. Such a big brand and they Donot have any escalation mail IDs. Just a stupid escalation matrix and primitive forms.
Their service centres in and around Mumbai are severely ill equipped and the personnel ill-behaved esp. if you don't purchase additional unnecessary material from them
Purchased another brand in replacement which I won't disclose to maintain the ingenuity of my review above.
