For a small room like this 1hp is more than enough. Request that they get another aircond service man to check from Lg. Waste money buying another one when it can be repaired and 6 mths is under warranty. If they are giving you the same excuses tell them to join this thread and come argue with us. If it is really true then LG aircond cannot match most other mades 1hp to 1hp in performance and you know it since you had use your old one.

I got a Toshiba 1hp never have problem since 199x, move from old house to apartment in 2000 and then to my present house in 2001 and now is still working. Never refill gas whatsoever. It is quiet except since this is a very old model it takes a bit longer time to start. I have a 2half hp from Panasonic it is good and cool since 2005 but the compressor is noisy since installation, service man is excellant when call to replace compressor but still no different and the Sanyo 2001 when it starts it give you a loud noisy everytime it on/off. Another Sharp is also ok silent since 2001. Of all these brands I would go for Toshiba and Sharp, you need no service man. Other brands not use before so cannot comment.

But when we look for aircond we also look for other features like if it filter air, ion, killing micor organism, etc.

I dont think LG can be that bad, i mean the aircond cooling capability, something else is wrong. Get them to show you similar model now running at other customer places or their office or get someone service man to look at it when you service other aircond. If it is true as said then there is every reason for them to replavce this unit then trying to rectify. You should write/email LG korea and request that they reply you if thier product is wayoff Toshiba. A big corp MMC will not allow their image to be tarnished and their engineer will be fired.

Havey Norman only sells they dont service so they dont know la.

I also have a Toshiba vaccum cleaner for more than 15 years. This thing just simply dont spoilt. Just that the tube have to replace due to wear and tear.
