I'm using Micromax 1.5ton split ac since 17 months.i think its perfect time for review. I have used this ac in temperature up to 45 degrees and for 15 hours a day.believe me it never disappointed me.my room size is also 1512. I live on the top floor. I myself was very surprised by the performance of this ac . cooling is very very effective, power consumption is also at par with other brands.although I will say it's a little bit noisy but still I would recommend to go for this product. I just purchased it because my budget was limited, but I'm very satisfied with this ac.it has copper condenser.just go for it.
