It offers robust cooling power and features smart controls through LG ThinQ technology, compatible with Amazon Alexa and Google Assistant, allowing remote operation. The unit has a cooling capacity of 24,500 BTUs and an Energy Efficiency Ratio (EER) of 10.3, which is decent but not the highest in energy efficiency.

This air conditioner operates at a relatively low noise level of 50 dB on low settings, though it can reach up to 61 dB under some conditions, which may still be noticeable in quieter environments. It includes three cooling and fan speeds and a dehumidification function that can remove up to 1.8 pints of moisture per hour, enhancing comfort further. Additional features include a user-friendly digital control panel, a timer, a filter check reminder light, and a power failure auto restart. The installation kit and remote control are included, but note that the unit is quite heavy at 132 pounds, which may pose challenges during installation.

The lack of Energy Star certification may be disappointing for those seeking maximum energy savings. Nonetheless, the convenience of smart features and the strong cooling capacity make this air conditioner a solid choice for larger spaces. The 24-hour timer and the filter check reminder add extra ease of use.

The unit also features an LED display, multiple modes and speeds, a 24-hour timer, and an ECO energy saver mode.

Despite its strengths, the unit has some limitations. The heating function only works effectively when the outside temperature is above 41°F, potentially limiting its usefulness in colder climates.

Its cooling power is solid for this space size, offering three fan speeds and an auto cool mode, so you can adjust airflow to your comfort level easily. One standout feature is its quiet operation, with noise levels as low as 52-53 decibels, which is gentle enough not to disturb sleep or work.

The 24-hour timer helps save energy by allowing you to set when the unit turns on or off. Its energy efficiency rating (SEER 13) is average compared to newer, more efficient models, so electricity costs may be moderate. The unit does not have a high Energy Star rating, which is something to consider if you prioritize energy savings.
