I had bought an Panasonic AC 3 Star since before 2 year. And I like this AV. Because it is giving a very good cooling even after 2 years. Also the maintenance of this ac was not so much.
I had only done its maintenance in last summer 2014. That was nothing I did. Just a person from the company came and remove all the dust from the AC. THen after it works so good. And gives very good cooling
I am having an office of 400sqft and it just makes in cool in less than 10 minute. In this hot summer of 2015 this AC really worth alot for me.
