10 Best Window Units 2025 in the United States

The LG 12,000 BTU Smart Window Air Conditioner is a solid choice for cooling medium to large rooms up to 550 square feet, such as kitchens or living rooms. Its cooling power is strong for this room size and it offers flexible comfort with three fan speeds and 4-way air deflection to direct airflow where you want it. The unit runs quietly at about 52 decibels on low, which means it won’t be too noisy for daily use.

Energy efficiency is decent with a SEER rating of 12, which helps keep electricity use reasonable, though it’s not the highest in the category. Installation is fairly standard for a window unit, with dimensions around 22 x 24 x 15 inches, so you’ll want to check your window size before buying. A key advantage is the smart features: it connects to WiFi and can be controlled remotely via the LG ThinQ app or voice commands through Alexa and Google Assistant, making it easy to adjust cooling even when you’re not home.

Additional features include a dehumidifier, a dust filter with a reminder to clean it, and an auto restart function after power outages. On the downside, it does not have a formal energy star rating, and it weighs 81 pounds, which might be a bit heavy to install alone.
