Doesn't really cool
Purchased first one came cracked as if it was already used. Exchanged it for another one, this one does not cool. My old 8,000 btu Frigidaire ac made my space cold this 12,000 btu ac barely cools it down. Very disappointed with this purchase!!

Runs quiet, great features.
[This review was collected as part of a promotion.] I bought this air conditioner on August 9th. It is so much quieter than my old one and it keeps my house cool. I run it on the energy saver mode most of the time, so it cycles on and off periodically and I am sure that it will save me money on my electric bill.

WiFi rocks
[This review was collected as part of a promotion.] Love my new LG 12000 BTU SMART WI-FI ENABLED WINDOW AIR CONDITIONER. It cools the needed area in my house perfectly. The WiFi feature is totally convenient when I can use the app on my iPhone to turn it on from anywhere.it sure is nice to come home to an air conditioned home.

It's very cool!
[This review was collected as part of a promotion.] This air conditioner makes me cool all day long. It works pretty well, I was having issues with the reset button but it was resolved. It's pretty nice.

Quietly makes room comfortable!
Finally got my AC installed! Directions were useless; family members installed it for me but it leaked into the house? I hired a handyman from Angi and he had had experience installing ACs and it's working like a charm! What a blessing in this awful heat and humidity!

Delivers the Goods on all Features!
I am so glad I bought this LG Thin q 12000 BTU window unit. It delivers on all promises. It is actually quiet. It cools more than the recommended square footage. It was easy to install. Everything needed to make installation efficient was in the carton. The filter is easy to access. The remote is effective at 30 feet. Thank you LG, for making an excellent product.

LG AC LW1217ERSM
I used the AC for the first time last night, and it was great. It was quiet, cooled off the room very quickly, and we are very pleased with our purchase.

Cools a large open concept area.
Used it a couple of times and good so far. Only had the unit for a week, it's a 2 man job installing the unit.

Great features, easy to install, quiet operation.

Terrific machine far better than expensive priors
I'm the guy who always tends to spend top dollar on things. This is my second LG replacing units that cost almost twice as much (think German for "Fred"). Much much quieter, flawless operation, feels solid. I'm pretty stunned at the quality/cost ratio here. This is my go-to brand now.

Cool and comfortable
During this extreme heat purchased this air conditioner and life is much better and cooler. l G is my brand of trust worthy merchandise. Not my first LG product. Actually my third.
