Professional delivery and installation is available for every product we sell. We would be happy to coordinate delivery and installation for you.

Extended warranties are usually very inexpensive and can save you thousands in the future. Some can even cover extra costs that result, such as cost of food that spoils when your fridge dies. It's simple and inexpensive to purchase extended warranties and one of the smartest ways to protect your investment.

Appliances can be large, heavy and expensive. You probably don't have the special tools or expertise needed to fix them in a crisis. If you can spare a few thousand dollars without batting an eyelash for new appliances should they break tomorrow, don't buy a warranty. But if you're like most of us, protect yourself by purchasing inexpensive extended warranties when you buy a new product and save yourself big money in the long run.

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.

Noisy but cools well

Crane 10/6/2018

The noisiest air conditioner Ive ever owned. Cant believe how loud it is when the compressor kicks on. Have an older version of this model and it is far more quiet. But it does cool well.

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

We bought this A/C through Amazon on Prime Day. Not only was it a great product that replaced the old worn out LG almost identical but it was a great price for the product and free shipping. This A/C cools a huge part of our home. Also I like that you dont have to pull the cover down to get to the filter. It is just slips out now. YAY

Cinder62 7/28/2018

Bought this about a month ago was going in for surgery so needed a cool environment to recover. The unit froze up it took a day to thaw. Now we can only cool for a few hours it gets very cold in here then shut off or change to fan. Too large to return.

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...

good and noisy

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.

Pretty Quiet

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.
