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.

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?

Terrible

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.

Perfect

shelby65807 11/12/2019

I waited for some VERY cold weather to review this item last night we had a low of 10 degrees with a wind chill of -5 degrees. This unit is WONDERFUL it blows a lot of nice warm air way better than a space heater and way safer Blows heat with the same airflow as it does air conditioning. Well worth the money but will need more than one person to install it is very heavy. love that I dont have to cut a hole in the wall just put it in the window

LG AC Wall Unit with Heat

SCalGal 10/18/2019

Used in a small 450 sq ft studio. Have been using it now for about 5 months. Live in the hot desert climate and have only used the AC function. It works perfectly. Wish it was a little quieter. Seems a bit loud but I am getting used to it. Soon I wont notice the sound. Havent used the heater yet and will soon. Winters can be chilly here. Will update review if needed. But very happy with the LG unit. Filter is very easy to remove and clean. But the Clean Filter light stays on all the time as a reminder to do it. All in all I LOVE IT This updated model replaced an older version of the exact same item.

Quiet and cool

Jazplus2 7/22/2019

We got this a/c to replace our previous LG model that finally gave out. This new one is quieter than the older model and cools much better We are taking advantage of the energy saving mode and it seems to be working perfectly. It has been installed for two weeks now and we are very satisfied.

Superb

This wall unit cools the room extremely quickly. When the weather is hot and humid outside this unit keeps the room very comfortable and dry inside. However this 18000 btu air conditioner does require a 240v outlet for power.

We have been using for a month now and love the air circulation we get out of this unit. Still waiting on electric bill to see the difference.

I am very happy with my purchase and my home is comfortably cool. The unit has clean lines and being able to control all functions remotely is a bonus.
