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.

Works great

Marlola 9/27/2022

I bought this for my elderly parents. The a/c they had was old and stopped cooling the apartment. It never really worked great. That are so happy with this one. It reaches into the kitchen and all and they love the comfort of the remote control.

Exactly What We Expected

Drummerjones 8/1/2022

Weve had this unit for several months and last month our old LG Thru-the-wall unit finally surrendered after 13 years. We installed the LT1216CER just before a long intense hot spell covered our area. We knew of the LG quality and reliability and this unit provides great cooling. We set ours on auto and the unit does the rest. Very pleased.

Extremely Loud

001274 7/6/2022

Our apartment complex replaced all our wall ACs with these things and they are the loudest AC Ive ever encountered to the point I cannot run it when trying to sleep which is wonderful as its often 90+ at night. There is no difference in sound level between the fan speeds. I measured the noise level and it runs at nearly 80 db not 60-65 like the listing claims. All three units in our apartment are that loud. The lights for settings/temp control are also very bright but cannot be turned off. If you are sensitive to light when trying to sleep have fun.

Very Disappointed

Eagle M 5/31/2022

We purchased two a/c units for use in an apartment building for a customer of ours. One unit worked fine. The other unit had a broken fan blade upon arrival and just hummed when we started it. This was an upper apartment with a couple with a baby. We didnt have time for the authorized repair dealer ordered the new blade and repaired it so we purchased a 3rd unit. We checked the box for damage and started it up before we installed it. Same thing. Just hummed and fan not turning. We ended up ordering a 4th unit so we would could provide cooling. Now we have two extra a/c units waiting for repair. NOT REAL HAPPY.

So Pleased

Cool in WI 5/18/2022

We actually purchased our new LG air conditioner last fall but couldnt find anyone to install it so left it in our storage shed over the winter. Great timing- we had it installed and in three days we had several 90 degree days. We were so pleased that our new unit cooled our entire three bedroom home 1250 sq ft. We even had to turn it down.

great buy

Geo 29 9/25/2021

Bought LG in wall AC 1200 BTU after our central ac gave out. Hesitant at first never owned this type of ac unit or LG product. We were extremely happy with purchase. Easy to install my husband did it. Quiet 3 speeds cooled entire family room and living room. Area of approx. 18ft x 30 ft. Very satisfied with efficiency during July and August heat wave.

Works well for my apartment

Jack 56 9/1/2021

The unit both cools and heats my small apartment well. I replaced my previous unit which lasted about 4 yrs with this one. Ive noticed that the compressor on this one makes more noise. Id feel better about the product if it lasted far longer than the warranty. Keeping my fingers crossed

Ok but not the greatest

Jolynn68 8/18/2021

I bought this as it was the only one that would fit my smaller sized sleeve and ran on a 110 plug. It was also the largest BTU that I could find for what I needed. It does cool but if left on energy saver shuts off before the room hits the set temp. It was decent priced for a sleeve AC.
