Works great.....once you can get it assembled


The LG room airconditioned cools the room nicely; like the "Dry" function for the days its not so hot but still humid. That said, they couldn't have made the "assembly directions" any harder.....the illustrations don't really agree with the written...

This thing cools half my house!


Love it. Never used the remote. Cooled half an 1100 sq/ft house with it. Never a problem with it. Electric bill did not go up with 2 of these instead of my central air.

Sizing is everything


This cools an L shaped room with one end containing the kitchen on the west side of a house in Houston TX. Overall size of the room is about 450 sqft.

Just a great product


Pros: remot, ability to use a universal remote, cooling is >= what it says on the box. Install was easy and recommend cleaning will be easy due to not having to pull the whole thing from the window. Also uses the water runoff to help cool the rear...

Great value for a great price.


Great air conditioner, cools of 2 rooms well (about 500 sq.ft.). The last one I had was a 14,000 BTU unit but it was 20 years old and broke down in the heat wave. This one is 12000 BTUs but works much better. I would have gone for more BTUs but they...

Works great in Steamy, Humid Florida


Bought this unit about 4 weeks ago, to replace one that was older and not functioning. Within the first hour of having it on, the room temperature was cooler and the humidity went down quickly. As it has been drastically hot in the last few weeks, I've...

The air conditioner works great.


The air conditioner cools my bottom floor (about 900 sq ft) with no problem. Consumer Reports was right. The value of the unit is well worth it!!

Easiest Installation I've ever seen.


I have two of these AC Units. The first was purchased last summer, and is still working great over a year later. I am pleased with the cooling capacity, noise level, and energy efficiency.

My favorite feature is that the filter is easily removed and cleaned.


I am very happy with this air conditioner. It is more quiet than our old unit and puts out cool air during the hottest of days. It took 2 men and a strong young man to install it, but I think that goes for most big window units.
