Bought this AC in Dec 2002 - Compressor - conked off in 3 years - heard there is 5 years warranty on the compressor - heard from service center in 24 hours of complaint - They told me that the gas needs to be replaced as it has leaked. So it is not covered under warranty. So had to pay Rs 1600 for replacing the gas. AC works like new after filling the GAS.
LG seems to have a good Service network and the staff responded within 24 hours. Also they send a VAN to pick up the AC. Since no VAN was available to drop back the repaired AC, So I had to go personally to pick up the AC.
It is better to get the AC serviced every year and also to get the cooling coils painted so that carbon does not get deposited on the coils, which causes the gas leakage.
