Don't buy Samsung AC, they are not best for the ACs. I have taken 1.5 ton inverter AC by seeing 10 years warranty they have provided that makes me in soup. By raising complaint regarding chillness also no use. Service engineer comes and tell some stories and go. They won't rectify the complaint properly. My Samsung inverter AC works through out night and feels mild cool. One more thing temperature as you set wont work, Always you need to keep in high cool mode only. Ideally you need to keep in this mode only to feel mild cooling. Don't waste you money by buying useless AC other wise you also become one more victim like me.
