I purchased an LG split system inverter air conditioner expecting a high-quality and reliable product. Instead, I encountered a serious design flaw – one of the indoor units turns on by itself and starts blowing hot air into the room, even when it is not set to do so. As a result, the room becomes unbearably hot instead of being cooled. I contacted LG customer support, hoping for a solution, but their response was completely unacceptable. Instead of fixing the issue, they suggested that I buy new air conditioners at my own expense! This is absolutely unprofessional and unfair customer service. I expected better quality and support from LG, but I am extremely disappointed. I would not recommend this product to anyone! If you value your money and peace of mind – stay away!
