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 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.

The LG 10,000 BTU Smart Window Air Conditioner is designed for medium-sized rooms up to about 450 square feet, such as bedrooms or small living areas. Its cooling capacity is solid for this size, providing comfortable temperature control without overworking. One of its standout features is the Dual Inverter technology, which not only cools efficiently but also uses about 25% less energy compared to standard units that meet Energy Star requirements. This makes it a good choice if you want to save on electricity bills. Noise-wise, it operates quietly, especially in sleep mode at around 44 decibels, which is gentle enough for nighttime use. At regular operation, noise can be up to 58 decibels, which is average for window units and generally unobtrusive.

The unit offers multiple fan speeds and modes to customize airflow. Although specific CFM airflow numbers are not provided, it should provide decent air circulation given its size and power. Being WiFi-enabled and compatible with LG ThinQ, Amazon Alexa, and Google Assistant adds convenience with remote and voice control, which is handy if you want to adjust settings without getting up. Other useful features include a dehumidifier function and a filter light reminder, helping maintain air quality.

On the downside, the unit weighs 63 pounds, which might make installation a bit challenging without help. Also, while energy-efficient, the initial cost might be higher than simpler models. The 1-year warranty is somewhat basic, so consider that for long-term reliability. This LG window AC is well suited for users looking for a quiet, energy-saving, and smart-controlled cooler for medium rooms.
