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.

Top notch window air conditioner

BSL in California 9/30/2021

I purchased this window air conditioner to replace a similar unit already installed. This new one is quiet has additional features that the old one did not have and is functioning perfectly. The instructions were beyond adequate. I am very pleased with the appearance of the unit and the quality also. The remote control is an additional feature that I thought was not going to be needed but has turned out to be a major convenience. Highly recommended

Perfect So Far one month.

Manofsixties 8/7/2021

The energy saver mode keeps it running fairly quietly. Low cool at 73 keeps the living room and foyer comfortable. Looks like monthly reminder appears to clean filter. Not sure but front opens at bottom and machine wedged against metal bar guard?

Horrible Warranty Response

CeleLister 7/31/2021

I purchased this air conditioner in May 2020 along with a 3 year extended warranty. The fan had to be replaced in June 2020. On July 3rd 2021 fan broke again. Two weeks later it was replaced but it never worked afterward. I have called emailed and messaged the technician several times and left messages they have not called back. It is July 31and my AC is still not fixed.

Continued Excellence

Cmungia 7/26/2021

I bought this unit to keep team members safe during the heat that Texas always delivers during the summer. This unit was enjoyed by hundreds of our team members to help from experiencing heat exhaustion and it worked great. I ended up buying another unit recently of the same brand but a little bigger and this one is just as reliable as the last. Than k you LG for helping me keep my folks safe

Doesnt Cool

barkster 7/22/2021

I bought this one about a year ago to cool my insulated garage never blew very cold at all. I wanted to take it out and return it which I should but was a pain. It lasted about year and a half not it makes loud clanking noise and doesnt cool at all. I typically lean towards LG products but this will probably influence my next purchase.

This appliance was terrible

Lake Martin 7/4/2021

This appliance was terrible. It was a heating/ air conditioner wall unit for a vacation home was seldom used. The fan started making a loud noise at the end of the first season but the unit was still working. When we went back to the vacation home this season the noise sounded like an airplane taking off and then the motor stopped after a short time. About the 3rd time we used it the motor quit completely. Of course when I called they said it was out of warranty. I would love to get the $500 for writing a review so I could recoup a part of my cost for this appliance.

Works well but noisy

Jim1973 4/29/2021

I bought this unit for a bedroom over my garage. It moves a lot of air and keeps the room warm or cool when need. However it has an annoying rattle that appears to come from the vent. I have tried to quiet it by stuffing small pieces of cardboard between the gaps. That seems to work a little bit for a little while. Im still working on placement of other makeshift wedges to stop the rattle. Also it cycles on and off very frequently on the energy saver and heat modes. Since this is a bedroom the two above complaints can make sleeping a challenge. One other issue I had was the manual is not the best. It was difficult to follow the directions for installation and the pictures were small and hard to see the detail. I would have given a higher rating if it were not for the noise.

Great unit

MrRod 1/27/2021

The unit works well. I did have a problem with the alluvial fan inside. 3 of the 5 blades were broken before we installed it. The box and cover for the unit were undamaged but the fan already was. With LG customer service the process of contacting a repairman and getting the repair made was exceptional. That was the only problem and it was resolved both quickly and professionally.

Product is just what we needed

MommaKat 1/25/2021

We bought this unit to replace one just like it that we had for about five years. This unit like the one before it works just as it was described. A simple cleaning of the filter and unit maintains it working. It easily changes from AC to Heat and in our Texas weather that is pretty often. It makes the transition without hesitation and it very sufficiently cools/ heats a garage that was converted onto a man cave.
