What People Are Saying

Rated 5 out of 5 by from Great Unit Bought this unit and two 8000btu units Kept my 980Sq foot cabin cold all summer and was easy to keep clean. All three worked beyond expectations with the 3rd party attachment to enhance ACs and would keep a walk in cooler as low as 33 degrees, my coolers 14x20 coolers never got above 38 degrees or below 33 degrees. Great units for home cooling or anyone that wants to push them to their full potential. Attaching the KB most likely voids the warranty though :) have recommended to dozens of other market farmers many of which helped shrink the stack of LG ACs at our local Home Depot. Spanked the competing units in performance.

Rated 5 out of 5 by from a smaller unit, but great working the unit is a little smaller than the old one and a little lighter, but it works great and puts out the air. i am cooling a 495 sq ft garage and it took about a day to get it down but now it is stable and nice.

Rated 5 out of 5 by from Excellent window unit! I bought this A/C at the beginning of this summer to put in my 350 sq. ft. sunroom on the west side of the house. It has worked extremely well to keep the room comfortably cool with mid-90's temps outside. It's also pretty quiet.

Rated 4 out of 5 by from Cools very well I bought a 12,000 but LG window air conditioner and installed it on August 3, 2017. Cooled great and was quiet. August is warm here in the southwest. Around August 22 nd, the unit''s fan stopped. Just buzzes. Have been waiting for a service person or warranty replacement since. There was some misunderstanding by the Customer Service people I first spoke to. They only heard that it "was noisey". They failed to hear it was not blowing or cooling. That delayed their warranty response. It is moving forward again. Luckily, my apartment has a swap cooler, but it does not help my allergies to have the windows open all of the time. Hopefully, now that I have faxed in the papers they want I will get something done.

Rated 5 out of 5 by from Great so far Had no trouble installing, AC is much quieter than the GE that I had to return. Cooling great so far, look forward to many years of service. Have now programmed the WiFi part yet.

What is the lowest temperature setting? As in how cold can it get a room?

Asked by: MistyPierce10
The temperature on the ENERGY STAR® LG 12,000 BTU Window Air Conditioner, Model # LW1217ERSM can be set between 60°F ~ 86°F (16°C ~ 30°C). How cold it actually gets a room will depend on what the external temperature is...^IFV

How do I connect to the internet

Asked by: Dbuggy
To use the Wi-Fi, the Smart AC must be registered on the Smart ThinQ website. To activate the Wi-Fi on the A/C, you must press and hold the Fan Speed and Mode buttons on the REMOTE CONTROL for 2 seconds. The Wi-Fi indicator on the A/C display will light up when it is active.

Where is the filter

The air filter would be located behind the front grille on the unit. If you require assistance with removing the front grille, more information can be located in the owner's manual on page 20.

How do I close the vent?

Asked by: Unknown P
We appreciate your interest in this air conditioner. The FRESH AIR DUCT stick protrudes from the Air Vent. Pressing this stick inward will close the vent.
