What People Are Saying

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.

Rated 5 out of 5 by from So Quiet I bought this A/C a few weeks ago and it cools my home quickly and quietly. It is simply the best quality I've had. I tried three other brands at comparable prices an LG is simply the best. It has wifi, energy saver, sleek clean design and a company who does back up their product. My summers are hot and humid outdoors. Inside with my 12,000 btu I'm cool, dry and peaceful.

Rated 4 out of 5 by from It works but you'll need to use wifi I have a few complaints about this air conditioner first that it's remote has a ridiculously short range for such a large BTU unit. Secondly unlike other brands not only does it not feature an air cleaner (ionic) the remote doesn't communicate the temp of the room to the unit (which I suppose is just as well considering the god awful range.) So this means you'll have to decide what temp to set the unit based on your comfort level. I do like that it's reasonably quiet, its high err rating, and the wifi control, but not having something to cut down on pollen when you use it on fan mode bringing in cooler air from outside is annoying. 3.5 stars rounded to 4.

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

Asked by: Jodielee
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.
