No one in the race right now, because the Voltas Split AC 1.5 Ton is enough to fulfill the all requirement of cooling . it has a good cooling and sound capacity to maintain the all primary thing about cooling. I have no dought about their quality and durability and reliability because it is famous for all above these ability. their service and support are also better than other brand of AC so I like it mostly .it is available in very cheap rate in the market .it has also a big advantages, it continuously gives better service since many years.
