We bought this and installed it ourselves. It keeps our 752 sq ft home super cold and has helped immensely with humidity issues as well. Have had some trouble hooking it up to ThinQ, but otherwise it has been a super solid investment so far.

LG never fails to impress! Works much better than our old unit and makes my home more comfy when its 90 degrees out

I bought this unit almost 3 weeks ago after my old unit compressor started going out during 100+ degree weather. It couldn't keep out living room cool at 68. This new bigger unit keeps our living room, dining room & kitchen very comfortable at 75 - 77 with the same 100+ temps outside.

I bought this as my previous AC unit was showing signs of giving up. The removable casing and the many features made this my choice. Once the lightweight casing was installed, the insides were easy to lift and slide in place. No more wrestling with the entire unit trying to set it up.

Due to a house fire, i was unable to use the air conditioner when I purchased it. Almost 1 year later, I finally got to install it in the house I am renting until my home is ready to move back in to. I am so Extremely Happy with the unit! It works like a charm!

It has been a good air conditioner. It replaced not just another air conditioner but also a space heater. When I first got it I wasn't sure I had made the right choice. I did. Very happy with the LG Air conditioner and heater.

I purchased this AC unit because summers are hard on HVAC in Houston Texas and it has done more than the job intended. We have to turn it off because it chills the back of my home so well....love it!!!
