10 Best Ac Coolers 2025 in the United States

The LG LW2524RD Window Air Conditioner is a powerful unit designed for cooling medium to large spaces up to 1,560 square feet. With a cooling capacity of 24,500 BTUs and an Energy Efficiency Ratio (EER) of 10.3, it is relatively energy-efficient, although not the highest in its class. One of its standout features is the quiet operation, producing only 62 dB of noise, making it suitable for home environments where noise could be a concern.

The unit offers versatile cooling options with three cooling and fan speeds, along with an Auto Cool feature that adjusts the temperatures automatically. Convenience is enhanced with easy-to-use electronic controls and a remote, allowing you to manage the settings from a distance. The Auto Restart feature ensures that the unit resumes operation automatically after a power outage, which is a handy addition. The 24-hour digital on/off timer allows you to schedule the unit to turn on or off according to your preference, adding another layer of usability.

This air conditioner also functions as a dehumidifier, which can be beneficial in humid climates. However, at 130 pounds, it is quite heavy, and installation might be challenging without assistance. Additionally, while it has earned a 1-star Energy Star rating, it may not be the most energy-efficient option available. The LG LW2524RD comes with a standard 1-year limited warranty, which provides some peace of mind. This unit is best suited for users looking to cool larger spaces with a device that offers convenience and quiet operation, though those prioritizing top-tier energy efficiency might want to explore other options.

The LG LW8023HRSM is a smart window air conditioner designed for small rooms up to 330 square feet, suitable for bedrooms or home offices. It offers a cooling capacity of 7,600 BTU, which is effective for spaces of this size. The unit has a Seasonal Energy Efficiency Ratio (SEER) of 11.3, suggesting moderate energy efficiency, which helps keep electricity bills reasonable. Noise level is about 50 dB, which is relatively quiet for an air conditioner, so it won’t be too disruptive while running.

This model stands out with its smart features, including Wi-Fi connectivity and compatibility with voice assistants like Alexa and Google Assistant. You can control the temperature and settings remotely via an app or voice commands, adding convenience especially if you want to adjust cooling without getting up. It also includes basic controls like two cooling and heating speeds, a programmable timer, and an auto-restart function that kicks in after power outages.

The multiple fan speeds help customize airflow for comfort, and the unit also acts as a dehumidifier, which is beneficial in humid climates. The included accessories like a remote control, window panels, and a one-year warranty add to ease of use. This LG unit is a reliable, moderately efficient air conditioner with smart features for a small room, making it a suitable choice depending on your cooling needs.

The BLACK+DECKER 12,000 BTU Portable Air Conditioner is designed for cooling rooms up to 550 square feet, making it a good choice for medium to larger spaces like apartments or living rooms. Its three-in-one design combines air conditioning, dehumidifying, and fan functions, offering versatility for different weather conditions. The Follow Me remote feature is handy, as it lets the remote act as a thermostat, helping maintain a comfortable temperature more precisely. Installation is fairly simple with the included window kit and exhaust hose, and the unit is portable enough to move around as needed.

Its energy efficiency rating (SEER 2.6) is on the lower side compared to some other models, which means it could use more electricity during operation. The noise level at 53 dB is moderate—noticeable but not overly loud, similar to a normal conversation. While the unit has an auto water evaporation feature to reduce the need for manual draining, its water capacity is relatively small at 0.5 liters, so it may require occasional attention in very humid environments. This model suits users seeking a straightforward, multi-functional portable AC with effective cooling for larger rooms, but those particularly concerned about saving energy might want to explore more efficient options.
