Very Good Product

Giraffemom 9/8/2019

I choose this air conditioner for a couple of reasons. I needed something large enough to cool 500 sq. feet in a west faceing house in the deep south. I also was replacing an air conditioner on a 230V system and didnt want to rewire. I have had it for three months during the heart of a very hot summer. It has done an excellent job of cooling. It is Energy Star complient and getting my first bill after a full month of use was a pleasent surprise. It came up short of five stars for two reasons. One its noisy. You can expect that from large air conditioners and after a month of constant use it quietened noticeably. Either that or I got used to it. Second it is BIG and heavy. I live in an old house and my window sash wasnt at all happy trying to support that much weight. I strongly suggest extra support unless you have really strong windows. All things considered expecially cooling and energy use I highly recommend this product.

Good unit

HDMWHO 8/14/2019

So far this air conditioner has functioned very well and I consider it to be slightly better than the previous unit which was also a LG product. The new unit has slightly higher noise and vibration levels but it is also slightly larger and hopefully it will have the same long reliable life span of the previous LG window unit it has replaced. Sadly the climate controls and cooling modes are the same as the older unit it replaced and they were the source of the few irritations we had with the older LG window air conditioner unit. The energy save feature of sampling the air by starting the fan is a source of noise especially at night and in the case of our partially underground house it actually uses more energy than the air conditioners with inferior thermostat designs that do not periodically force air over the temperature sensor. I have no doubt your periodic forced air sampling works well in a standard home but our partially underground home will often go hours even on the hottest days before the unit actually needs to turn on the compressors and cool. The constant cycling to test the air simply waste energy and worse yet adds unneeded noise to our home especially at night. As mentioned above the controls and operation modes on this LW1816ER are almost exactly the same as the older LG units controls and they have the same problem. You really need to add a few more options to the energy saver mode such as giving the user some way to widen the time intervals between the unit forcing air over it temperature sensor.

LG 18000 BTU window air conditioner

rob1951 4/22/2019

I have had this 18000BTU AC for 9 days. It cools as good as my last LG 18000 AC which is great. The only complaint I have is the compressor on the new one is very loud it interferes with the TV and conversations. The old one you could barely hear the compressor running. The old LG 18000 BTU AC lasted 4 yrs. till the compressor quit cycling and stayed on continuely. You had to unplug the AC to cut the compressor off. Plug it back in the compressor would come back on. It still through snow balls at you. I have had many different brand ACs over the past 40 yrs. LG has the highest air flow and gets colder than all I have owned. Also the old one used the least amount of electricity of them all. Hopefully the new one will be the same.

Crane 10/6/2018

Ok then Lets Review

thecrow 8/10/2018

I purchased this unit from Amazon. I received it dented and inoperable. I pulled the sheet metal surround off. The fan motor shaft had been bent causing the fan to hit the fan surround and the freon line was snapped off the compressor. I havent received a replacement yet. I only gave this review because LG keeps emailing me requesting a review.

Mike it is my name 8/7/2018

This is third unit of this basic model Ive had and have been happy with all of them. Hopefully this one will out live expectations as well. One thing ticked me off You had to increase the height of the cabinet by 7/8s of an inch which required me to install the new one rather than just slide in the new unit. Extremely aggravating

Great Cooling AC but has some cheaper parts

JMPAL 7/11/2018

This AC cools with ease but the fan directional guides are very cheap and hard to use so air doesnt go where you want it... also when you turn the AC off it defaults to Energy Saver Mode when you turn it back on... not a great feature we always have to turn it to Cooling Mode when we turn it on...

noise hater 7/6/2018

The unit cools very nicely but the noise is deafening even on low fan. I cannot discern any difference in sound among the three fan speeds. Unit has many good features and a remote. But the noise is so loud that when the energy saver mode cycles to off you think that the world has stopped the noise was so loud that the silence is actually momentarily alarming.

Goosey Moose 7/4/2018

Have been running it non stop for two weeks and it nearly froze me out the first night had it on 68. Now it is on 78 and cools three of my rooms to a comfortable range and is quiet enough to let me sleep. The price was very affordable and installation was easy. Just would be better if there was more adjustment to the directional vents.

My only issue so far is the noise and that the demensions on the spec sheet online and provided by Lowes was wrong the units hieght is considerably more. I later noticed this had been revised. Luckily the unit still fit my window. Someone with a specific demension requirement may have been greatly disappointed.

Islandboy 3/9/2018

Installed as a Wall unit...make sure some air vents extend to ouside the wall. Says your options are not changed if Power goes out. Unit always starts in Energy Saver mode so it will shut down when desired temp. is reached. Only way to defeat this is to select COOL mode each time you turn it on so that Fan keeps running when temp. is reached.
