10 Best Room Air Conditioners 2025 in the United States

The BLACK+DECKER 10,000 BTU Portable Air Conditioner is designed for rooms up to 450 sq. ft., making it a good choice for medium-sized bedrooms or living spaces. Its cooling capacity at 10,000 BTU is solid for this size, but note that the effective seasonal cooling (SACC) is lower at 5,800 BTU, which may affect efficiency in very hot conditions. The unit has a respectable Energy Star 5-star rating and a SEER of 6.7, meaning it will be reasonably energy-efficient compared to some older models, helping to keep electricity bills in check. Noise-wise, it runs at about 52 dB, which is fairly average for portable ACs—noticeable but not too disruptive during daily use or sleep.

Installation is straightforward with the included window kit, and thanks to built-in wheels and handles, the unit is easy to move between rooms without much hassle. The 3-in-1 functionality means it can also act as a fan and a dehumidifier, adding extra comfort on muggy days. The washable slide-out filter is a practical feature for easier maintenance and improving air quality.

It comes with a remote control and a 24-hour timer for convenience, though it lacks smart home connectivity features, so it won’t integrate with voice assistants or mobile apps. This BLACK+DECKER portable AC offers solid cooling, decent energy efficiency, and useful features for easy setup and operation, making it a strong option for those needing flexible cooling without advanced smart controls.

The BLACK+DECKER 8,000 BTU Portable Air Conditioner is a solid choice for cooling smaller rooms up to around 300-350 square feet, making it suitable for bedrooms or small living areas. Its cooling power is effective for personal use, and the unit also offers fan and dehumidifier functions, which adds versatility during different weather conditions. The remote control with a 'Follow Me' feature is a handy addition, allowing the remote to act as a thermostat for more precise cooling, which many users will find convenient. Mobility is another strong point here; with side handles and wheels, it's easy to move the unit between rooms without strain.

Installation is fairly straightforward thanks to the included window kit, though being a portable unit, it requires venting through a window which might not suit all setups. On the downside, the energy efficiency ratio (EER) is on the lower side at 5.4, and the unit is not Energy Star certified, meaning it may use more electricity compared to more efficient models, potentially increasing energy costs. Noise level is moderate at 54 dB, which is typical for portable air conditioners but may be noticeable in quiet environments or during sleep. The product doesn’t specify advanced air filtration features, so it might not be ideal if you need enhanced air cleaning.

The unit has a relatively short 1-year warranty and weighs about 46 pounds, which is manageable but not ultra-light. This BLACK+DECKER model provides a practical, easy-to-use option for those needing portable cooling in small rooms without the need for advanced smart home integration or high energy efficiency.

The BLACK+DECKER Smart Portable Air Conditioner offers 12,000 BTUs of cooling power, suitable for rooms up to about 550 square feet, making it a good choice for medium-sized bedrooms or living spaces. It’s a portable unit, so you can move it around as needed without permanent installation, and it comes with a window kit for easy venting. One helpful feature is the “Follow Me” remote, which acts like a mini thermostat to keep the temperature just right where you are in the room. It also supports smart controls via an app and voice commands through Alexa or Google Assistant, which is convenient if you like smart home gadgets.

On the energy side, its efficiency ratio (SEER 5.8) is moderate but it’s not Energy Star rated, so it might use more electricity than some more efficient models. Noise level is around 52 dB, which is noticeable but generally acceptable for a portable AC—it's quieter than many similar units but might still be a bit distracting in very quiet environments. The unit also functions as a fan and dehumidifier, adding versatility. However, it doesn’t specify a special filter type, so if air purification is a priority, this may not be the best fit. The water evaporation feature helps reduce manual draining, which is convenient.

This AC is well suited for users who want flexible cooling with smart features in medium-sized rooms and are comfortable with some noise and moderate energy consumption.
