I am using panasonic split ac for the past several years.Though I have another reputed brand but I can clearly see the difference in terms of performance, electric consumption, noise factor etc. Every time I compare with other brand I am using , panasonic stands on the top. I save lot of money because of low electricity consumption and super fast cooling capacity. Also it operates very silently. In my view panasonic split ac is the champion performer. So, friends if you are planing to buy a split ac then do not think twice and go for panasonic.
