Well voltas is a giant in air condition industry.I bought these AC from online site in 25000 rupees.Some how its sound is high enough but cooling is efficient.
The size is quite bit big in comparison to another AC in these range.If room size is 120sq-ft then it will be very good for that room.As these is a window AC it will be some difficult at the time of installing but its remote range is very good.Maintenance cost is also low.
