I myself bought a Whirlpool AC and so did my in-laws.they bought 3 split ACs from Whirlpool. Initially I was quite hesitant about buying a Whirlpool AC.for so many years I have known them as a ref or a washing machine company.But a friend of mine who is an engineer told me about their 6th Sense technology and explained it to me in laymans term.and I saw great sense in it.
Unlike other ACs where gas is injected injected through 1 capillary which takes longer time to spread through the evaporator coil, Whirlpools MPFI utilizes a unique 6 circuit design which ensures rapid injection of the refrigerant for faster cooling. And these multiple capillaries ensure faster and efficient cooling at lower power consumption.I even spoke to some of the dealers.and they explained to me that in a year Whirlpool saves more that 2000 bucks on electricity bills over an LG or a Samsung.
Frankly I saw no reason not to go in for Whirlpool.And believe you in me . I am loving it. It cools really fast . my wifes loving it too .:)
