I have been using whirpool ac for the last two years that too in Noida wherein condition of ground water is literally worst but let me tell you honestly whirlpool ac is performing more than my expectations if you compare the price with other it’s almost 30 to 40 percent cheeper than other brands. I had purchased 3 star which is good in electricity saving also. I would definitely recommend to buy this product. In some reviews observed that some people are annoyed with the service requesting you to contact company directly
