Used for years Good A/C's Warranty coverage sucks
Installed a new, out of the box, LW1821ERSM and it stopped running within 24 hours. Electronics in cover defective. Tested with cover from another new unit and ran perfectly.

I am not very encouraged b...

Cheap plastic cover produces loud noise
It does the job, but the plastic cover that goes around the front of the unit is cheap plastic that tends to vibrate excessively and produces a very distracting noise.

Response from Staples :
Hi, Jerry. Thanks for sharing your thoughts on the LG Air Conditioner (LW1821ERSM) model. We’re glad to hear that the unit meets your needs. However, excessive vibration and noise from the plastic cover can be quite distracting. We strive to provide top-notch products that exceed our customers' needs and expectations.
To address this, try tightening any loose screws or fittings around the cover. Sometimes, securing the cover more firmly can reduce vibrations and noise.
Please send us a private message on social media @LGUSSupport if you continue to experience issues or need further assistance. We’re here to help and ensure you get the best performance from your LG unit. ^Juvy

So far, so good.
While it required an electrician to come in and install the special outlet, so far it’s producing a really exceptional amount of cooling to our commercial kitchen.

Great Product
I had to buy a new air conditioner during one of the hottest weeks this summer. I must say that this air conditioner works great! I like the timer feature and how much quieter it is from my old one. I would recommend this model.

Cools Beautifully
We purchased this air conditioner couple of weeks ago. It is Big and beautiful. It cools beautifully but one of the faults I have is the snapping sounds it makes when it kicks in and out constantly. It is in our living room where we both sit and it constantly clicks and clicks. The second fault is I cannot adjust the vents. I originally got them to point up but I c...

This unit is quiet and cools one room to cold and doesnt distribute the cool air like my previous unit. The energy efficient newer units are not cooling efficiently unfortunately
