If any one planning to buy AC, I will advise to find contact details of the brand and check up if contact through phone is available. In case of Hitachi India, I have tried to contact their branch office in NOIDA, Corporate Office in New Delhi, branch office in New Delhi and HO in Gujarat.
Either no body picks up the call or phone is switched off. Never ever buy Hitachi product. Their service is NIL and authorized service center is cheating. BEWARE OF HITACHI BRAND NAME. THAT IS WHAT MY EXPERIENCE IS IN CASE OF AIR CONDITIONERS. NOT ONE BUT WE HAVE 15 AC SUPPLIED BY THEM
