Hi, Glenn. Thank you for sharing your experience with your LG Air Conditioner (LW1017ERSM1) model. It’s impressive to hear it’s cooling a much larger area than it’s rated for. That model is designed for efficient, steady cooling, so it’s wonderful to know it’s keeping your space comfortable and exceeding your expectations after just a few weeks of use.

Quiet and convenient

My smaller air conditioner died out after a few years ( a hand me down)!
I have a 8000 BTU in my livingroom I bought from a family member, works very good! But for my 450 square foot apartment the 10000 is a pleasure!

Energy saver mode is the best feature of the unit.

[This review was collected as part of a promotion.] Our old AC broke just before summer and I had a friend who had this same AC in his apartment. We ordered it a few weeks ago and it runs like a dream. It’s quiet, programmable and does an excellent job of maintaining a comfortable temperature in our apartment (which is saying something, because we live in an old building that is not very well insulated). We will be getting this brand AC going forward.
Pros: ease of use, Quality, Style/Design, Performance
