Good Heat Noisy Highly Inaccurate Thermostat

Professor Gerry 12/22/2020

I bought this unit about a month ago to heat an eat-in kitchen and cool it in the summer. It heats well. However it is loud. The thermostat is widely inaccurate. The instructions are very poor. I wont know how well the air conditioner works until the summer.

Dont buy

Pebble Brook 7/15/2020

We purchased this unit in June 2019. We used it a few times then went to FL for the winter. When we returned in June 2020 we turned it on. It cooled 1 time then quit working. An LG repair person said it has 2 leaks would cost as much to repair as to replace. Obviously we will not replace with another LG product. We are very disappointed with this product. As far as we are concerned it is a piece of junk.

Broken after 1 minute

No heat in Austin 1/10/2019

Bought it one month ago. Ran for 1 minute before fan failed. First repair visit unable to fix. Next visit from a different tech should happen soon? Approaching 4 weeks with a failed unit.
