The kelvinator split AC was good. It gives smooth air and chill. Keeps us always fresh. Raising the level more, the air gets much chiller and its good to be under that. But it can be more properly designed to get freshness easily. It sounds at times which is very noisy. I use to off it 2-3 times and only then the sound goes off. Sometimes the chlillness gets low and feels like uncomfortable. Not good!
