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.

Demo man 3/21/2021

Window ac Unit lasted less that 4 years now LG refuses to fix it. I bought a 5 year warranty from Home Depot Asurion and still not working for over four weeks. Asurion says its under LG warranty and LG says because of the out door elements they arent responsible. The unit is designed to be out side. Not happy

Hmmmmmm?

WalkinNSunshine 1/15/2021

I bought this in September 2020. I bought the heating and cooling unit because the back of the house does not cool or heat as well as the front. I can turn the air on and it will run continuously or I can set it at energy saver and it will adjust when it gets cool and cut off and then resume when the temperature gets higher. The thing I hate about the heat part is that its always on energy saver and it takes forever to heat up my small room and bathroom. You cannot just turn the heat on and leave it on it automatically like the air cooling it goes to energy saver automatically and you cant adjust it to run continuously to heat the room. The unit will run for about 60 to 90 seconds and then cut off. Then it turns on again in about 2 to 3 minutes to warm again. It can be 60 in the bedroom but it continually cuts on and off. It takes several hours for the room to actually warm up If I had to do it again I would just have bought an air conditioner and a small portable heater. When I turn the heater unit on now it sounds like theres a tiny noise in it. If it wasnt so heavy and hard to uninstall I would definitely return it. It cost a lot of money for something that does not work like I thought it would.

Satisfied in Shreveport 12/26/2020

These LG Electronics - LW1816HR room ac/heater units are just great. Installation was manageable the display features are easy to understand but best of all we like the fact that a desired temperature can be set and you can rest assured that it will maintain it. Just wish they werent so pricey but... you get what you pay for right?

Will2021 12/11/2020

I bought this product April 2020 once the weather started changing to hot the unit wouldnt put out cold air from June to September my wife went back and forth with LG warranty trying to get it fixed with no results. We paid good money for the warranty and it was terrible. We finally took the unit back to Home depot and they was nice enough to refund the money back. We will never purchase an LG product again.

My new LG A/C

Paul60 12/7/2020

I bought this to replace an old Fridgedare init. It was fairly easy to install by myself and had common 220v connection. Cools two rooms easily and quietly. Auto setting is great as it shuts off when temo I set is reached. And runs little after set tem reached saving lots of energy. Now its cooler and HEAT function is great as it keeps room warm easily. I am very happy with this unit.
