The LG 10,000 BTU Through the Wall Air Conditioner is designed for spaces up to 440 sq. ft., making it ideal for bedrooms, living rooms, and apartments. With an energy efficiency ratio (EER) of 10.7 and R-32 refrigerant, it promises efficient cooling while being environmentally friendly.

Users appreciate its easy installation and sleek design, especially the through-the-wall trim piece that enhances aesthetics. The unit operates quietly, ensuring it doesn't disturb sleep, and comes with a simple remote control for convenience.

However, some users reported issues with the unit's performance during extreme heat conditions. One user noted that the unit stopped blowing cold air when outdoor temperatures exceeded 85°F. Despite troubleshooting efforts, the problem persisted until a repair technician suggested that venting under a deck might be causing the issue.

On the positive side, many users praised its cooling efficiency even during heatwaves. One user in NYC reported maintaining comfortable indoor temperatures in the 70s despite outdoor temperatures reaching 95°F. The unit's three cooling speeds and energy saver mode were also highlighted as beneficial features.

Noise levels were a point of contention among reviewers. While some found it relatively quiet, others described it as somewhat loud but manageable as white noise in urban settings like NYC.

Overall, if you're looking for an efficient and stylish wall-mounted AC unit with straightforward controls and decent performance under normal conditions—this could be your pick! Just be mindful of potential limitations during extreme weather scenarios.
