Today I am gonna share my personal review on Hitachi Ac. I purchased Hitachi invertor AC around 1.5 year ago. The maintenance and service is not good also the sound of AC is loud enough, after 6 months or a year Which is very bad. Also AC gas leaking problem.also I have been registered many complaints over customer care but those complaints are closed before anybody turns up to inspect the AC. NO mechanic has ever visited to check the AC. there are different messages that we receive every time stating that the complaint has been closed. So please dont go for it.
