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.

Second Unit But A Great Decision Nonetheless

HotorColdTexas24 10/4/2024

This is actually the second unit within a 6 month window window unit ha ha. The first one was a LG as well and it did a great job for about two - three months. Then it stopped cooling suddenly. It was hot in that room. Called LG support and wasnt able to get anyone to look at the unit however when calling back was able to reach a tech and the questions began. They were many but Im glad we did it because we discovered the first unit was not able to cool the space. We took it out and returned it to Home Depot they were able to credit it because of their policy - Thanks HD and we decided to go with LG again because it all made sense that we had to go up to the 18000 BTU coverage. Weve reached the first two months and we are very pleased. Thanks LG I did not get this for free or at a discount but was asked to review for a sweepstake entry that probably wont be me winning that

Doesnt work

DMKCibolo 9/8/2024

I bought this July 5 2024 - it stopped cooling around August 8 2024. Went through you CS line to get it fixed or repaired and it still has not been completed. I have waisted 2 days of work waiting on the service company and nothing has been done.

Confused on filter.

jak1425 9/2/2024

Our contractor purchased the product for our attic while it was being remodeling into a bedroom. It continually shows a red light for the filter to be cleaned. Is this normal? We have only used the cooling no heat used in August.

Great choice

ALOVE 8/14/2024

We bought this unit to replace the one we had that had just quit working. As the temperatures were in triple digits we needed one quickly. This is the updated version of the one we had so we opted to buy it. We feel that this was a wise choice. It works like a champ.

Did not last 2 weeks

BrianB987 7/26/2024

I bought this 18000 BTU AC unit about a month ago. I mounted it in the wall with the help of a neighbor 130lbs replacing another 18000btu unit that lasted 20 years. I lasted 2 weeks and stopped blowing cold air. I called LG for a service call. I had told them I had to leave about 3:30. They got there after 2. They said I had to remove it from the wall I had difficulty doing that. They left as they said they could not do anything when it was in the wall. Also they do not repair them just replace them. I decided just to return it not wanting to risk getting another one that would last 2 weeks. No ability to give 0 stars.

Cooling down

Kojk 6/26/2024

Highly recommended. Using less electricity than my fridgedaire 18000 BTU unit. Recommend a platform type installation for safety in window mounting. The only draw back it is alittle noisy when compressor is running.

I have had my air conditioner for 2 weeks and I am thrilled with it. I love the remote control and the ease of using it. I would definitely buy this same one in the future.
