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.

Has electrical issues does not work.

Douglas Henderson 9/17/2021

This unit was purchased by me online May 3 2021. I have a new build going on and was unable to install the unit until recently. The unit pops the breaker every time its plugged in to its 220 V receptacle. Now I am without. I have requested repair and was told that repair was unavailable and they were looking into alternate resolution. This is how I need to heat and cool and I am somewhat disappointed.

Customer Service and Warranty is WORTHLESS

vans1000 8/2/2021

I purchased 4 units for a rental property. 1 unit works great 3 units did not work at all electrical issue with unit possibly. All outlets tested at 230V. Purchased 3 additional units those work great. Cannot seem to get a refund on the defective units from LG even though LGs Certified Technician couldnt fix them. Life is not Good.

I bought my ac/heater unit in March I just really had to turn it on and I love it. It cools the room very well here in Houston we reached 90 degrees on Tuesday 5/4/21 and it kept the room very cool and comfortable. I ove that it came with a remote that makes it easy to turn on or off when Im in bed. Im very happy with my purchase.

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.
