An year ago we bought a split air conditioner of Hitachi. Its really amazing as it makes the room cool within fifteen minutes.
The remoye of AC is made with radium which does not create any problem even in dark. Whenever it works it gives the mild sound which is not harsh to the ears.
The reliability of this product is above than its average as it could not control itself during some circumstances.
We paid RS 37000 for this air conditioner which is quite alright as if we look for its features
