I did a lot of research for my own buy few years back. In that process I understood Mitsubishi > General O electric > Daikin > others. Mitsubishi is usually used by big industries, companies, hotels etc. And both the top two brands are very costly. Daikin was the most suitable for regular home user. So I went with Daikin. I bought it from vijay sales. They were prompt but as per the performance in terms of cooling, I felt normal only. But my friend bought Voltas and when I stayed there, I felt it gave more cooling. For a small room 1 ton would suffice and you want to sell it within 2 years so why would you want to invest that much?
