Owned 2 unit LG aircond in my house and it serves me good over 5 years and counting. My gf also using LG and its all good.

The most lousy aircond brand i came across is Acson and Hisense.

Just bought the new Samsung Inverter 1hp virusdoctor and will install it next month during room reno and see how it goes

Everyone have their own preference as i experiencing kimchi brand not bad at all during my usage.

Like car, even high end or most reliable also will break down so there's no absolute choice.
