Works great, but pay attention to detail
VertisaG Posted
I ordered a 15,000 BTU per the info on the website, however when it was delivered it showed a 14,000 BTU. I called customer support thinking the wrong item may have been delivered, but they told me the serial number registers to the 15K BTU and to look at the unit in the box and call back. As I desperately needed AC, I accepted the 14K BTU, and works great, but I think the website is misleading.

Fantastic Unit
TANIAN Posted
It did everything I needed it to do. With temperatures in the 100s every day for over a month and a landlord that will not repair the central, we really had to have a window unit and this one worked great.

Exactly what we need.
MORGANB Posted
This A/C is performing exactly the way we expected it to. Cooling efficiently, quiet. Cycling off and on in the most effective way. We've been buying LG A/C's for years and they are the best. And Best Buy had a very efficient way or ordering.

Defective
KimA Posted
Front panel would not stay attached to the AC cabinet. Had to use tape to keep it from coming off. Had one just like this unit for 14 years and it was great.

Hi, Kim. Thank you for sharing your feedback regarding your LG Air Conditioner (LW1521ERSM1). We understand the importance of a secure, proper fit and long-lasting quality for your home comfort, and we are committed to helping you get this resolved. Here are a few steps to ensure the front panel is properly seated: (1) Align the bottom tabs of the front grille into the slots at the base of the cabinet before snapping the top section into place. (2) Examine the side plastic locking clips or screw mount locations to verify they are fully engaged and free of obstruction or debris. (3) Make sure the washable air filter is fully inserted, as a misaligned filter can stop the front cover from closing properly. For more guidance, visit https://www.lg.com/us/support/product/lg-LW1521ERSM1.AT1AUSH?. Please send an email to us at lgdigitalcare@lg.sprinklrsupport.com so we can look into panel resolution options with you. We're ready to assist! ^Juvy
