When I buy this split ac, Firstly it keeps cool my house within a minute 1.5 5star then I thought it will blow my electricity bill but it is 5 star rating at the next month I saw the bill was an average the price of voltas 1.5 ton split ac is average to money service is better cooling is very fast and generally this ac niether sounds this ac has given a specific satisfaction to me and I thought a new ac buyer must own this ac this is the best AC I ever seen
