My friend has bkight an Hitachi AC, and now he is dissapointed with his selection.
The main problem with the AC is that it stops the cooling effect after regular use.
Sometime we may have set the speed on 17 but still it give cooling of 28.
Different parts are difficult to be repaired and the customer services are not up to mark.
After some use the AC starts generating loud noise as if some cooler is functioning.
So if you ask me I would never suggest you to go for this.
