I purchased this 12000 BTU unit to replace a 10000 in the living room in May of 2018.  It is now August 2020 and it has stopped working properly.  It still runs but the compressor will not kick in.  I have tried all that LG said to do to reset it but to no avail.  I really had faith in LG since the little 6000 BTU in one bedroom has been in use since 2013 and still works like a charm.  My recommendation is if you are going to purchase this or any unit also purchase an extended warranty with it.... they don't make them like they use to, sorry LnG (Lifes not Good).
