10 Best Low Profile Window Air Conditioner 2025 in the United States

The LG 12,000 BTU Window Air Conditioner is a solid choice for cooling medium-sized rooms up to 550 square feet, making it suitable for bedrooms, living rooms, and apartments. It operates at a relatively quiet noise level of 52 dB, which is beneficial for maintaining a peaceful environment, especially during sleep or work. The unit offers three cooling and fan speeds, along with an Auto Cool feature, giving you the flexibility to customize the cooling according to your preference.

The digital control panel and remote control enhance its usability by allowing you to adjust settings conveniently from a distance. Additionally, the 4-way air deflection ensures even cooling throughout the room, and the included timer lets you set a cooling schedule to save on energy costs. However, the unit's Seasonal Energy Efficiency Ratio (SEER) of 13 is decent but not the best, and it is not Energy Star certified, which might be a consideration for those looking for the most energy-efficient options.

The dimensions and weight of the unit are fairly standard, but it’s worth noting the product’s size to ensure it fits your window. Installation is made easier with the provided window installation kit, and maintenance is simplified with a slide-out, washable filter and filter light reminder. In summary, the LG 12,000 BTU Window Air Conditioner is a reliable and user-friendly option with some energy efficiency limitations, ideal for medium-sized spaces where quiet operation is valued.

It operates quietly, producing noise as low as 53 decibels on its lowest setting, so it won’t disturb your sleep or conversations. The unit offers three different fan and cooling speeds, allowing you to customize airflow and temperature easily. You can control it either through the digital panel or the included remote, adding convenience.

The washable filter and filter reminder help keep maintenance simple.

The energy efficiency ratio (SEER) is 13 and it does not have an Energy Star certification, which means it may use more electricity compared to more efficient models. Weighing about 58 pounds, it’s moderately heavy, so installation might require some help. One handy feature is Auto Restart, which turns the unit back on automatically after a power outage.

This model is well-suited for general home use and offers quiet, reliable cooling. It provides a good balance between ease of use, noise level, and cooling power for typical bedroom or apartment needs, although those focused on maximum energy savings might want to consider other options.

Installation is pretty straightforward with its compact dimensions (about 12.8 x 17.3 x 11.1 inches) and it includes a trim kit and mesh filter for basic upkeep. The unit also features an auto restart function to turn back on after power outages, ensuring steady comfort without extra hassle. However, it has a Seasonal Energy Efficiency Ratio (SEER) of 11.5 and is not Energy Star certified, so it might use more electricity compared to higher-rated models. Its cooling power is suitable for average rooms but not large spaces, and while it offers useful features like dehumidification and a filter reminder, the warranty is limited to one year.

Weighing 37 pounds, it's manageable for most window installations but not extremely lightweight. This LG air conditioner is a reliable and quiet option for those needing effective cooling in smaller rooms, with easy controls and decent features, though it may not be the most energy-efficient choice on the market.
