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.

Excellent Air Conditioner

DS177 6/28/2024

We purchased this window air conditioner in May for cooling our downstairs area. It works so well in cooling is quiet and we receive notices on our phones if an issue occurs such as the filter needing cleaning. This air conditioner is actually 1000 BTUs less than the one it replaced and cools much better. Highly recommend.

POWERFUL

Bionic 6/28/2024

I waited a long time for this AC due to the size...it was extremely important because it went into my wall. Im extremely pleased with the power and all the functions. The only thing disappointing about my AC is the MAIN PANEL on the RIGHT was dented most likely by lifting from the forklift arms making the front main panel to close in properly I can not move my vent panels up or down. Otherwise I would still recommend this AC as it has been a sheer PLEASURE

Stuck with a brand new $500 broken ac.

2mad 11/6/2023

I purchased an ac and it arrived broken. Amazon replaced it and it worked for almost 2 months. We started having issues with and contacted Amazon and they said its past their 30 day limit to contact LG. I contacted LG and have received the run around. They said they would send a tech 2 weeks later said they didnt have a tech in my area. Then it was that my ticket was being sent for a resolution of replacement or refund. That was a whole different run around. Several times I talked to different people and they had me sending pics of serial numbers receipts from amazon. Every time I wouldnt hear from the resolution team and was then told to resend everything. About the 5th or 6th time on that merry go round I gave up calling. Now Im stuck with a broken $500 ac. I will never buy another LG product even if its only a dollar.

Do not buy RUN

2mad 10/7/2023

It broke less than 2 months after receiving it and the issue still has not been resolved. They are good at giving you the run around on the warranty while you sit and sweat with a broken ac.

I bought this unit in late August because a heat wave was coming. It worked for two days and then the electrical board burnt out Had to wait a week before you sent a man to replace it By then the heat wave was over. Major disappointment

Great Ac

Little dave 7/4/2023

We bought this ac 2 years ago. It is phenomenal in its ability to cool. It will blow ever so lightly when the temperature gets where you want. It then just barely blows and keeps it cool. Our power bill has gone down about 25. We keep it on energy saver.
