I liked the unit when it was working on the air conditioner tried to switch it to the heater side did not work and LG is working with me to get it corrected. Lot of time involved and paper trail but I hope that they will get issue resolved soon.

This AC/Heat unit was bought for a tiny house. It doesn't heat well enough to warm even close to the unit. The AC worked pretty well this summer. The unit just went out. It was only 1 year & 1 mo old. It glowed and then stopped working. Save your money - don't buy this thing.

I’m pleasantly surprised at how quiet the unit is for its size. I bought a 12k btu with heater AC unit and found it so much quieter than smaller units i have used before.i have it for about a month but haven’t used it much but so c far it’s beyond expectations

Over the years, I have grown to like this brand. My first product was a LG TV, and it lasted over 10 years, until lightning hit it. Ended up getting another one, and it is as good, or better. Now, to the AC. At first, it seemed to be a little loud, mainly when the compressor came on.

I bought this unit for a bedroom over my garage. It moves a lot of air and keeps the room warm or cool when need. However, it has an annoying rattle that appears to come from the vent. I have tried to quiet it by stuffing small pieces of cardboard between the gaps.

Great heater!! We haven't had to use the AC yet but this puts out a lot of heat and get our room toasty warm in a few minutes. Great buy :)

I purchased this window air conditioner to replace a similar unit already installed. This new one is quiet, has additional features that the old one did not have, and is functioning perfectly. The instructions were beyond adequate.

I installed through the wall to heat and cool a small house. works perfectly ! I am impressed how quiet running it is.

We bought this unit to replace one just like it that we had for about five years. This unit, like the one before it, works just as it was described. A simple cleaning of the filter and unit maintains it working. It easily changes from AC to Heat and in our Texas weather, that is pretty often.

Keeps our small house comfortable even on the coldest nights. Haven't tried it during the summer yet.

Product Description

If you're cold, you're cold - even if it's May. That's why LG presents seasonal heating and cooling.

Enjoy the cool air even more with LG's 4-way air direction. By adjusting the deflection, air is directed up, down, left or right so you can move the air where it's needed most
