This unit stopped working less than 30 days after being installed. It was more than 30 days after the purchase so I had to deal directly with LG. Unit cannot be worked on because of the type of coolant so it was approved for an exchange (on 5/30/24) to be contacted within 7 business days. Still waiting 7/4/24! Customer service is weak. They seem to only be able to escalate/elevate 1 way regardless of the outcome. It has escalated dozens of times, including the Presidential Liaison team, but no one seems to be able to do anything! I've completed the Talk to the President area on the website twice in the last 30 days and have never heard from anyone.
