10 Best Portable Room Air Conditioners 2026 in the United States

The Whynter ARC-1230WN is a strong contender in the portable air conditioner category, especially for cooling medium to large rooms up to 600 square feet with its 14,000 BTU capacity (12,000 BTU SACC). Thanks to its dual-hose inverter technology, it cools efficiently and quietly at about 42.5 decibels, making it less disruptive than many other models. The unit also includes a built-in dehumidifier that can remove up to 87 pints of moisture daily, which helps improve comfort in humid conditions. A convenient smart Wi-Fi feature allows control through an app or voice assistants like Alexa and Google Home, which is a plus for modern users. It also offers three operating modes (cool, dehumidify, fan) and a programmable thermostat and timer, giving good control over your environment and energy use.

The air filter is washable, reducing maintenance hassle, and the included window installation kit supports easy setup. On the downside, the unit is quite heavy at over 77 pounds, which might limit how easily you can move it between rooms compared to lighter models. It’s not Energy Star rated, so while it’s fairly efficient (SEER 12.3), it may use more electricity than the most efficient options available. The price and warranty terms are competitive but worth considering if you want longer coverage. This unit is well-suited for users who need powerful, quiet cooling with smart features and dehumidification for mid-sized rooms, and who don’t mind a bit of weight when moving it around.

The BLACK+DECKER Smart Portable Air Conditioner with Heat is a versatile choice for rooms up to 700 sq. ft. It stands out with its 14,000 BTU (ASHRAE) cooling capacity and 10,000 BTU (DOE), ensuring it can handle larger spaces effectively. With an additional 12,000 BTU heating function, it is a reliable option all year round.

Despite not being Energy Star rated, it offers a Seasonal Energy Efficiency Ratio (SEER) of 6.2, which is decent but might not be the most energy-efficient option available. The noise level at 54 dB is relatively quiet, making it suitable for bedrooms and living areas without causing much disturbance. Portability is a key feature, with dimensions of 16.5” x 14.06” x 27.09” and a weight of 35 pounds, making it easy to move around.

The included remote control with FOLLOW ME function and smart features, such as Wi-Fi connectivity and voice control via Amazon Alexa or Google Assistant, add convenience and modern touches. The dehumidification function and the programmable timer and thermostat are useful for maintaining a comfortable environment. However, it could require regular maintenance, particularly regarding the filter. The installation kit is comprehensive, simplifying the setup process. It is a well-rounded portable air conditioner with additional heating capabilities, though those who prioritize energy efficiency might need to consider other options.

The BLACK+DECKER Portable Air Conditioner, with its 12,000 BTU (ASHRAE) cooling capacity, is efficient for rooms up to 550 sq. ft., making it suitable for medium-sized spaces like bedrooms and living rooms. Its three-in-one functionality allows it to operate as an air conditioner, dehumidifier, and fan, adding to its versatility. The 'Follow Me' remote control feature is a standout, enabling precise temperature control by acting as a thermostat. This is complemented by the easy-to-read LED display for convenient operation.

Mobility is another strong point, with built-in casters and side handles making it easy to move from room to room. The included window kit simplifies installation, so you can get it up and running without much fuss. However, this model has a few drawbacks. The energy efficiency ratio (EER) of 5.8 is relatively low, meaning it may consume more electricity compared to more energy-efficient models. Noise level at 52 dB, while not overly loud, could be noticeable in quieter settings.

Maintenance is straightforward with an auto water evaporation feature, though the filter will require periodic cleaning. This portable air conditioner is highly user-friendly and well-suited for those needing a reliable cooling solution with added dehumidification and fan options. It excels in ease of use and portability but may not be the most energy-efficient choice for those concerned about electricity consumption.
