I bought this LG to replace an old unit with the idea that this would be the last air conditioner I would buy; this was more costly than what I have bought in the past at the "big box" stores but the features and my previous experience with LG appliances convinced me to make the additional investment.  So far I have not been disappointed.  The unit is very quiet and quickly cools the room down even on the most humid day. I like that I was able to connect it to the house wifi system and start it remotely if needed.  The energy saving mode is very effective. In all, I feel that the extra investment was well worth it given the features and efficiency.
