10 Best Casement Window Air Conditioner 2025 in the United States

The LG 18,000 BTU window air conditioner is designed to cool medium-sized rooms up to 1,000 square feet, making it suitable for living rooms or larger bedrooms. With 18,000 BTUs, the unit offers solid cooling power for its size. It has a good energy efficiency ratio (SEER of 18), helping to keep electricity costs reasonable. The noise level is about 52 decibels, which is relatively quiet for a window AC and minimizes disruption during use.

Installation is straightforward with standard window mounting and includes window curtain panels. However, the unit's size (about 16 x 20 x 12 inches) and weight (44 pounds) mean it might require two people to install safely. The electronic control with remote and multiple fan speeds adds user convenience, and features like auto restart after a power outage and a 24-hour timer enhance usability. The dehumidifier function is a useful addition for humid environments.

The warranty is limited to one year, which is shorter than some competitors. This LG model is a strong choice for those needing reliable, medium-area cooling with quiet operation and practical features. However, if longer warranty coverage or a smaller size is desired, exploring other options might be beneficial.

The LG 12,000 BTU Window Air Conditioner is a solid choice for cooling medium-sized rooms up to 550 square feet, such as bedrooms, living rooms, or apartments. One of its major strengths is its quiet operation, running at a noise level as low as 52 dB, which is ideal for those who need a peaceful environment for sleeping or working.

Additionally, the unit offers flexibility with 3 cooling and fan speeds along with an Auto Cool feature, allowing you to adjust the air flow according to your preference. The included remote control and digital control panel enhance usability, making it easy to manage the settings from a distance. The unit also features a 24-hour timer, enabling you to set a cooling schedule that can help save on energy costs.

Installation is made simpler with the provided window installation kit, and maintenance is convenient due to the slide-out, washable filter and filter light reminder. However, the device does not have an Energy Star rating, which suggests it may not be the most energy-efficient option available. Additionally, its size and weight could be a consideration for those with limited space or who require frequent repositioning. Despite these points, the LG 12,000 BTU Window Air Conditioner remains a versatile and user-friendly option for those seeking effective cooling and quiet operation for medium-sized rooms.

The LG 7,600 BTU Window Air Conditioner with Heat is a solid choice if you need a unit that cools and heats a medium-sized room up to about 330 square feet, such as a bedroom or office. Its cooling power is suitable for spaces around 16 by 20 feet, making it a good fit for typical apartments or smaller living areas. The unit is fairly energy-efficient with a SEER rating of 11.3, which means it should keep your electricity use reasonable, though it’s not the top of the line for efficiency. Noise-wise, it operates quietly at around 50 decibels on low, so it won’t disturb your sleep or work. Installation is straightforward since it’s designed to slide into most standard window openings, but keep in mind it’s fairly heavy at 69 pounds and sized around 21 by 18 by 14 inches, so you may want some help setting it up.

Additional features like a remote control, a 24-hour timer, two fan speeds, and a filter reminder add convenience and ease of use. The built-in heater function is handy for cold days, giving you year-round climate control in one device. However, the cooling capacity is on the modest side, so it might not be the best for larger rooms or very hot climates. Also, the product warranty lasts one year, which is standard but not extensive.

If you want a dependable, quiet air conditioner with heating that’s easy to operate and fits medium rooms, this LG model represents a smart pick balancing performance and value effectively.
