Hitachi 1.5 Ton RAU019IVEA is not a wonderful product. its not far better than Samsung. Its cooling is average. Hitachi Air conditioner’s service and support is very bad. cooling system is late and sound very hard. value of money cost is high. cooling system is 3 time late then samsung. mostly peoples I have ever seen are satisfied for this product. This is certified company as we all know & the service of the company is not good as samsung. you can buy it in you budget and I never recommended this AC to my Friends.????
