Great features

JackieBaucon 5/17/2023

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 its really good. The one I had lasted for about 15 years it served its purpose..

LG 18000 BTU AC

Emilienburgs 9/24/2022

This AC cools a room down fast. We are very pleased with the performance. Our den has 12 ceilings and is 22x20. The den is very cool during the day and cold at night. Easy to change temperature setting manually or with the remote. There is some noise but nothing that bothers our conversations or watching tv. The kitchen is cooler too Our house was built in 1947 so it has been hard to find an AC that works just good but this LG AC is awesome. It can get HOT here in south central Texas and this LG AC works GREAT

Terrif A/C

RHDoug 9/22/2022

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 its pretty heavy. Might be tough on a window sill. I am a happy customer.

Great unit for elderly Grandparents

Jpjoseph 9/7/2022

I purchased two of these units for my elderly Grandparents. The two existing units were the exact same model. Theyre 91 and 94 years old and were used to the controls and remote and change would be difficult. Theyre also very brand loyal and believe in the LG units for durability and trust. They would have no other

Exceptionally quiet

Bud1229 8/25/2022

Ive had this AC for about a month and use it most evenings. I mounted it through the wall which is a good idea because its quite heavy. I use it to cool about 1800 square feet and it does it with ease. Plus its exceptionally quiet. Great unit.

Doesnt work half the time

RockD 6/27/2022

AC model LW1816ER often doesnt blow any air at -- not even warm air. Ive unplugged it for 10 minutes cleaned filters tried everything. Was working on and off and now doesnt work much at all. I have two of the exact same units. One has been a constant problem for more than a year and now second one starting to have same problems.
