Hitachi Home& Life Solutions India is a subsidiary of Hitachi Appliances Inc, Japan and is one of the leading air conditioners manufacturers in India& Worldwide. Headquartered in Ahmedabad, Gujrat, the company has a major manufacturing plant in Kadi, Gujrat which is among the ten-Hitachi air conditioner facilities worldwide. They have been highly competitive in Indian Market by selling a premium range of Air conditioners which are best in looks when compared to other’s manufacturers in this sector Hitachi offers only a premium range of AC’s in Indian Markets. That means they are the costliest air conditioners and its price range gives competition to O’General AC’s. But premium cost doesn’t mean they expensive because of brand name, but its because they offers lots of features which makes them expensive but still cost gets justified when you buy brands like them or O’General because they have a very long run. It’s like one time investment and forget it. However a timely service and proper cleaning is a must to run a product for long time efficient Hitachi AC’s are very effective when it comes to cooling. Cooling rate is good and the room get cooled up quietly fast. These AC’s have a Twin Turbo Technology which increases the heat exchange when at high temperature and ensure a optimum cooling by not even overloading the machine capacity. The advantage of Twin Turbo Technology is that it is designed to throw air in both directions and provide higher air-flow at lower RPM, however in conventional AC’s, Sirocco fans are used on the inside and outside propeller fans are used, and these fans by design can’t throw air in both directions and hence lower efficiency on those. And due to presence of large number of blades, the air cutting noise is high resulting in high noise levels and lower efficiency. That’s why the number of blades present inside in Hitachi window AC’s are less, so this results in less cutting of air and hence more effective cooling. And hence due to use of Turbo fans inside and outside, the person get an increase on overall air-flow leading to higher efficiency even at lower noise levels Build quality of these AC’s are very impressive. And it should be as they are charging a premium cost for them. Front frame is made up of a good quality plastic and doesn’t give any cheap plasticity feeling. The frame is one of its kind and is unique with this company design. Overall finishing of the product is very fine and one must check the product from each corner while buying it. Because when company manufacture a product, it passes through every quality check, but the only thing which is not very traceable is transportation. So, one must check the product from every side and corner, that it must not have any single dent on it. If it has, never buy it
