Dear Mr. Ravi,
I have had a similar experience with Hitachi Quadricool 1 ton window ac. Please bear in mind that Electrolux is a good brand still as I have seen it in a friend's office. He uses it 10 hrs+. I am still thinking of buying an electrolux 1 ton split for home.
Many dealers dont care a damn once your payment is made. Most ACs come damaged due to poor logistics. My experience with Hitachi is the same. The call center at Hitachi is pathetic. I wished they change my new AC with other piece, but they would not. Atlast I have to bear with the damaged piece which I got from my dealer at Malad, Mumbai. It somehow works now, but nothing great to the 5000 Rs. Premium price I paid for buying a Quadricool AC. Finally the korean brands seem to be better choice than AMTREX HITACHI in todays market.
