The air conditioner I had played out in September of 22 and I needed another one. So I found the exact same brand and almost just like the one that quit and I bought a new one, it's really good. The one I had lasted for about 15 years, it served it's purpose..

I like it but I don`t love it. It is not as quiet as expected. I do not like two features. Once I turn off it automatically goes back to eco setting. I want it to stay at what I left it at. Second once I clean the filter the clean filter light stayed on. I tried everything.

I purchased two of these units for my elderly Grandparents. The two existing units were the exact same model. They’re 91 and 94 years old and were used to the controls and remote and change would be difficult. They’re also very brand loyal and believe in the LG units for durability and trust.

We bought this air conditioner from Appliances Connection online. The price was much better than other stores at the time. We actually tried to buy another a couple weeks later and there was a limited supply at higher prices. The unit is lighter in weight than the one it replaced.

This LG window ac unit is doing a great job of cooling a 20 x 20 room. Very easy to use, quiet and not too difficult to install. Very satisfied.

Maybe a little noisier than I expected. It is installed solidly. I can live with it. Cools nicely.

I have a 2014 version of this A/C. There might be some differences, but it looks almost the same. It has worked flawlessly for the last 8 years, cooling an 800 sq.ft. home even on the hottest days. I have it installed in a "through the wall" installation; it's pretty heavy.
