- A: Hi Irene, we understand your LW1224RD window air conditioner is set to 69°F but the room is still around 86°F, and we appreciate how closely you’re keeping an eye on its performance — especially since the filter is already spotless. This unit normally delivers strong cooling, so a few quick checks can help it return to full strength. Try these steps ⦁ Make sure the Outdoor Vent/Exhaust is fully closed to keep warm air from entering ⦁ Confirm the unit is in Cooling mode, not Fan or Energy Saver ⦁ Check that the window installation is sealed tightly with no gaps ⦁ Adjust the 4‑way air direction to spread cool air evenly across the room Model link for your unit https://www.lg.com/us/air-conditioners/lg-lw1224rd-window-air-conditioner If you need further assistance, feel free to email lgdigitalcare@lg.sprinklrsupport.com. ‑Rich11 days ago
Q: Does this unit have inverter technology? What is the seer rating?

- A: Hey there. Great question! The LG window A/C unit LW1224RD is built for reliable performance, but it does not feature inverter technology. Instead, it uses a standard rotary compressor to deliver consistent cooling. Its CEER rating of 11.4 reflects strong energy efficiency for a non-inverter unit. While SEER ratings apply to central systems, CEER is the trusted benchmark for window models. For more questions, private message us on social media @LGUSSupport.

Big A/C unit with lots of cooling power!
a year ago
I love my new 12,000 btu LG air conditioner. The install was quite simple if your windows are perfectly square, but mine are not. You must pull the center of the unit out first and install the outer frame first. It was quite challenging to put the faceplate on the unit at the end and get it to stay attached correctly. I was able to fix the situation. Overall the directions are simple and easy to follow overall. This unit sits in the window very sturdy so no worries of it falling out randomly. Other than that is has been amazing. The air quality is great. This Lg A/C cools my whole downstairs level fast and efficiently. It can handle 1000 square feet no problem. I can keep my living room, bathroom, bedroom, kitchen, and dining room at a nice and cool temperature all day long. I love when my house is cold during the summer and this will definitely get the job done. Its very quiet and runs smooth. I barely can tell it’s running. It also comes with a simple and easy to use remote. This is a big window unit so make sure it will fit before purchasing. LG is usually really good with the energy consumption but we will see in the future. Overall a great A/C unit to have, especially for big areas. I will definitely be comfortable and cool all summer long..

Great AC for a 400sq ft sunroom
a year ago
I recently installed the LG 450 sq ft window air conditioner in my 400 sq ft sunroom, and I’m very happy with the results. It cools the space incredibly fast—even on the hottest days, it makes the room comfortable in no time. Installation and removal are both straightforward, which makes it convenient for seasonal use.
One feature I really like is the adjustable airflow direction. Being able to change the wind side helps circulate cool air exactly where I need it. While the unit is a bit on the louder side, the sound doesn’t bother me—it’s a fair trade-off for the strong performance.
I also think it doesn’t use too much energy, which is a big plus, especially when running it frequently during heat waves.
Overall, this AC has been a great addition. It’s powerful, efficient, easy to use, and makes a real difference on high-temperature days.

Nice unit
a year ago
Good unit does what it meant to do cool and quiet, it's a little beast it does cool nicely and the dry out function seem to work to over all a great product with good air flow, easy install and you can definitely run this on a portable generator if you have 700w I would say it's energy efficient if you compare it to other units.

Good Quality AC Unit
a year ago
This air conditioning unit is the perfect size for a small space! It’s not too loud inside and the fan blows really strong. It comes with a remote which is nice! It also has the foam gasket to help insulate the unit and reduce any light coming through
