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.

Not good at all

Manuel Rico 7629 Tejon st 9/20/2022

I spoke with the technician and I was told because the item was fairly new that they had to replace it with a new one and never heard back from him after that point

Good features

Kostas22 7/28/2022

I bought it little bit more than a month ago and so far satisfied. Cooling really well also I like auto mode so it stops when temperature reached your desired setting. It is not very quiet as I would like but the noise is not worse than the other units I have.

Dead

My first LG product 6/18/2022

I bought this wall ac unit July summer 2021. It word really well for about 6 weeks. I went to turn it on for this summer the cooling and dehumidifier are completely dead. It just blows hot air into my home. It is still under warranty but LG is making it extremely difficult to get the unit replaced or repaired. They have terrible customers serve whom says they will call you back in 2-3 days but they never do. I would love to get my money back. I have been working with much difficulty with LG on this for over 4 weeks now. Zero stars

Cools the entire 2nd floor

John Petro 6/16/2022

We have two 15x15 bedrooms. The air conditioner is in one and when we put a fan in the hall to blow it into the other one in an hour and a half it cools it down beautifully. Works like a charm

Birdie69 5/30/2022

I bought this nine days ago. Today was the first day to use it. Im happy with it. I like that its an energy star. I hope to have it for several years to come. I had a white westinghouse for 23 years went out the last couple of hot days that we had. I love that it has a remote control.

Great overall

maxmd 5/22/2022

Does a good job cooling our entire 900 sq ft apartment. Looks good on the wall and appears to be of decent build quality. I only wish it was running a bit quieter but I cant ask more for the price.

Not cold enough

Gorden 11/2/2021

I have that unit for less than a year old. But hardly used it for summer and found out that unit was not cold enough. Called customer service and send three times. But cant figure out what is wrong. So still cant solve the problem. Find different brands instead.

Efficient but not reliable

RickG9 8/18/2021

We bought the AC from Amazon and it arrived well packaged. We used it somewhat regularly and about 2 months after we received the AC it started making a VERY loud banging noise. The Customer Service has been fantastic and were trying to get it fixed but the issues weve had are a bit disappointing. Hopefully once it is fixed it will last for many years.
