Very Bad product from Hitachi

This is worst then a locally assembled split AC. The indoor noise is in excess of 60 db though the company claims 37 db. The remote is not back lit as mentioned in the specs. The outdoor unit vibrates horribly and makes all kinds of noise.
I have three split ac's in my house and five in my office of different makes and this is the worst...even 20k LLOYDS AC's are way better then this,
I am pretty sure that these are all defective lots. I am going ahead and challenging Hitachi ( India ) and Hi...

Good cooling, but Noisy

Bought through offer site amazingofferonline. blogspot. in and got 1200 extra cashback
Hitachi ACs today are not very good which they used to be few years ago. I bought this AC Rs.26100 in APRIL 2015 which was 3000 higher when compared to other brands like LG, Carrier.
Indoor unit is small. Noisy because of airflow. Not use if it is due to cheap plastic Hitachi is using nowadays.
If you used hitachi AC earlier(like 10yr ago) thats is why you are going to buy this AC, I would strongly recomm...

1.Remote is not with back lit& buttons are not radium,so that every time i need to switch on my room light and i need to operate that remote.
2.No display unit in the AC.
3.blindly u need operate the AC.
4.cooling happens only in the cool mode, auto cool&dry mode fails to maintain the temperature. has fan adjustment (high,med,low). if I keep fan in high, then it is making horrible noise that I cant even sleep.

Among the Best in its class

After weeks of search online I decided to go for Hitachi 1TON AC as it comes almost in the same category after O general and Daikin. Flipkart delivered it on the day promised and was installed the very next day by Hitachi Installation people. They only charged the standard installation charge 451 rupees that was promised by flipkart. Any accessory that would not come with the AC would be charged extra. Some of the Pros and Cons i observed:

1) Hitachi Ac's are among the best
2) Cools wi...

Very Good AC

I ordered this AC and got delivery with in 2 days in Ludhiana. Prior to reaching at my home Flipkart called Hitachi to install it.
I am very satisfied by its service. The AC is also very good in cooling and its functions are very easy to understand. My room is 14X12 feet and it is serving the purpose.
Thanks Flipkart
