Voltas 185CY 1.5 Ton 5Star split AC. After much enquiry I have decided to take this for my house. It has 5STAR EER(Energy Efficiency Ratio) rating and as it indicates it consumes less power, and generates less noise I am using it since 8 months and it not generate noise much. It shows the consistent performance means it take very same time to cool my room as it take on its first use. Till this day it never give any trouble, not make me to call customer care service after its installation. I have used it in last summer almost 12hours per day and at that time also it showed best performance. It gives fresh feel all the time but not sticky or other irritation while using it for long hours. In my opinion it is best for household usage
