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.

I purchased this for a converted garage to make into my sons bonus room. The area is less than 450 square feet so I felt this model was a good choice. I always liked LG products but I believe this AC unit does not sufficiently cool down the room as designed. I hear the fan going but there is no consistent cold air coming from it. Even though I had it professionally installed and had a new outlet changed due to the AC unit plug design I believe I wasted a lot of money to have the LG AC unit acting merely as an expensive fan. I already threw out the box and packaging so I cannot return to Home Depot where it was purchased. If you have any suggestions to help please let me know. It just doesnt cool down the room very well. Thank you.

George in AZ 9/9/2019

We finally installed the unit a week ago and it works very well. Only one suggestion for improvement - the air deflector assembly is not very effective in directing the side-to-side air flow as the vertical deflector vanes are too short to deflect all of the output air flow.

rparker351 7/25/2019

I bought this unit just before the hot and humid Arkansas summer. I put it in a new office that is 388 sq. ft. The unit is rated for up to 500. It is more than adequate to cool off my space within minutes. The remote control is very handy

Cools Super Quick

Rick_Foresythe 7/25/2019

I bought this unit for my Sun Room which is an addition to my household so it had no access to my Central AC. Since the room has the sun blaring down on it most of the day from mid-morning through the evening I needed something that would cool the room off but also not break the bank. I was surprised at how quickly the unit cools the room off as I live in the Deep South and were just starting to get into the HOT part of Summer. I turn on the unit and usually within five minutes the entire room is nice and cool. The Eco-Mode for it also keeps the unit from leaving the compressor/fan running for longer than it needs to. I now use the Sun Room to keep my dog in while Im away at work for long hours. I was actually worried about how he would take to it as he is rather spoiled but he now sees it as his room often wanting to go in there and enjoy how nice and comfortable things are in there for him.

Best A/C Heater

BettyNOLA 7/18/2019

This is the 2nd LG AC/Heater unit weve purchased. One is at our cabin in the woods getaway and the other is in our office. Can cool our office 250 sq.ft from 84 to 73 in under an hour. Can heat up same size room from 57 to 68 in under an hour. Very easy to clean filter...I like the way it tells you when to clean the filter. Only negative item is no where on the box does it show you what side the plug is on. We didnt find out it was opposite of what we needed so my husband had to do additional work so it could be plugged in. Something you need to know for ease in installation but dont really think about when looking for an AC.

Didnt make it 6 months.

Steveymars 7/5/2019

I did a lot of research into window units that also heat well. This unit got good reviews and fit my window. Immediately the unit acted flakey on the heat setting. We had a mild winter in Austin and so we didnt use it much this winter and not at all in the spring. I went out and fired it up a couple of days ago and it ran for about an hour and hasnt turned on since. Hopefully LG will make it right and not give me the run around on the warranty.

Great Unit for Cooling and Heating

noisytree 5/17/2019

I installed this unit recently when enclosing a porch. It has been terrific doing a great job cooling the space very quickly. Much easier to heat and cool and less expensive than tying in to the whole house HVAC. I highly recommend this unit to anyone with similar needs.

Drives me Bananas

Brando420 5/1/2019

My landlord replaced my old unit which I had used personally for 17 years with this LG. It cools great and I feel very fortunate. However while trying to conserve energy I try to use the Energy Saver mode. It comes on every 3 minutes and then kicks off over and over again all day. For the life of me I cannot see how this is saving energy. I read on this site that it just comes on to check and see if it needs to cool the room. Well that makes no sense to me. How is it saving anything by coming on and going off all of the freaking time? I can almost hear the dollar bills flying out the window each time it does this.

Combination Cool and Heat

jcuwood 4/25/2019

This is the second identical unit that I have purchased. The first unit a/c portion began to fail last summer. It was clear that it would not make it through another summer here in the south. Although I am very pleased with the operation and features of both units there are come critical comments that I must make. The unit is designed to slide out of the outside casing to make installation easier. That would be fine if it would slide out easily. For some reason on both units the foam insulation or padding on the inside is so tight that not only is it very difficult to slide out but it actually damages the foam. I had the identical problem on both units and was disappointed to see that it still existed several years after my first purchase. The screws that are supposed to hold the side panels to the casing have a shoulder to prevent them from compressing the panel too tightly. The shoulder is too long and bottoms out before securely sealing the panel to the casing. A regular screw along with a cautionary instruction would be better. Also the length could be a bit shorter as I noticed that the almost interfered with sliding the main unit into the casing. In addition there were only 5 of these in the bag and should have been 8. I had to improvise. The black plastic frame guides for the bottom of the side panels are made of a thermoset material and thus are VERY inflexible. Getting them into the rectangular slots on the bottom of the casing was difficult at best. Finally my window design is such that I could only get approximately 1/8 of downward slope in the unit from inside to outside. If the top of the casing had slots it would allow the top bracket to be adjusted inward to allow for more slope. These may seem like trivial comments and I will admit to being critical. However I would expect more attention to be paid to the small details in order to make the installation go smoother.

Reyesfitness 1/10/2019

I bought it in April of 2017. It worked great but exactly one year later the fan broke. Thank God that LG gave me a complimentary service call. I would have expected it to last at least 5 years for the price I paid for it at Home Depot. Heater stopped working after the first winter. At least the cooling is still working. Parts are cheap material.

exTexanJim 9/7/2018

We bought this as a replacement for a not very insulated sun room at our house. Since the room is not connected to our whole house central AC/Heating system we needed something with a lot of capacity so that the room is available and comfortable for all 4 seasons. It works admirably well for us no complaints. And the remote control unit is great. It is a 220VAC product so make sure you have the room where you want it wired with a 220VAC outlet....

I live in a small mobile home in Florida where its very warm in the summer Imagine my excitement when I turned it on for the first time put it down to around 75 and within 10 minutes my entire living room and kitchen area were totally comfortable I was no longer sweating up a storm My cat Kizi was stretched out in front of it enjoying the cool air Thank you so much for making an air conditioner that I will enjoy all summer and also because it has Heat I will be comfortable

Operates as advertised

smitty19 6/22/2018

Our remodel contractor selected and installed this unit in our new sun room. This is my first experience with an LG product. So far operation is great and the unit cools the room quickly even though the room is exposed to this hot Oklahoma sun. The only reason I did not give it 5*s is that it is difficult to see which mode it is operating in in daylight conditions due to the dim indicators.This may be because we had to mount it low below the windows not at eye level.

Cant give it 5* until I test out the AC but the heater works well enough. Its in my tack room at the barn. Only 1/2 of the room is insulated so it has to work pretty hard to keep the 450 sq ft warm. Im hoping it is more efficient and less costly than running two ceramic towers.
