The LG 12,000 BTU window air conditioner is a solid choice for cooling medium-sized rooms up to about 550 square feet, like bedrooms, living rooms, or apartments. Its 12,000 BTU power means it can handle typical spaces without struggling. It operates quietly, at around 52-53 dB on low settings, so it won’t be a noisy distraction while you work or sleep. You get three fan and cooling speeds along with an easy-to-use digital control panel and remote, making adjustments straightforward.

The air conditioner also includes a washable mesh filter with a reminder light, which helps keep the air clean and the unit efficient. With a 24-hour timer and auto restart feature, it offers decent convenience and energy-saving options. However, this unit doesn’t have advanced smart features like WiFi control or app connectivity, which some users might expect these days. Its seasonal energy efficiency ratio (SEER) of 13 is average, so it’s not the most energy-efficient model but should be reasonable for standard use.

The installation kit is included, making setup easier for a window unit. Weighing 81 pounds, it’s on the heavier side but typical for this capacity.

Energy-wise, it has a Seasonal Energy Efficiency Ratio (SEER) of 9.7, which is decent but not among the most efficient models. It runs on a 230/208V power supply, so it needs a compatible outlet and may require professional installation, especially since it’s a through-the-wall type rather than a window unit. This setup is great for a permanent cooling solution that doesn’t block your window. Noise level is reported at 55 decibels, which is average; it won’t be completely silent but should be tolerable for most people, especially in living areas or bedrooms.

This LG air conditioner is a reliable choice if you want a combination of cooling and heating in a medium-sized room with a fixed wall installation. It is practical and user-friendly, but if you’re looking for quiet operation or smart home features, you might want to explore other options.
