10 Best Rolling Air Conditioners 2026 in the United States

The BLACK+DECKER Smart Portable Air Conditioner with a cooling capacity of 14,000 BTU (ASHRAE) or 10,000 BTU (DOE) is suitable for rooms up to 700 sq. ft., making it a strong choice for medium to large spaces. Its portability is enhanced by its relatively compact size (16.5” x 14.06” x 27.09”) and the included installation kit simplifies setup. Weighing around 62.4 pounds, it may still require some effort to move around despite its portable tag.

The unit operates at a noise level of 54 dB, which is moderately quiet but could be noticeable during quiet nights. The energy efficiency ratio (EER) is 6.2, which is decent but not the most efficient available. Users may see a moderate increase in energy costs with frequent use. This air conditioner also functions as a dehumidifier and fan, providing additional versatility. The washable filter makes maintenance straightforward, though regular upkeep is necessary to ensure optimal performance.

One of the standout features is the smart control capability, allowing users to operate the unit via a mobile app or through voice commands with Amazon Alexa or Google Assistant. The 'Follow Me' remote is a convenient addition, acting as a thermostat for precise temperature control. The air conditioner's smart features and remote control add convenience, but the somewhat lower energy efficiency and moderate noise level are points to consider. Its strong cooling capacity and added functionalities make it ideal for those looking for a multi-purpose unit to cool, dehumidify, and circulate air in larger rooms.

The BLACK+DECKER Smart Portable Air Conditioner with Heat offers a versatile solution for year-round climate control in rooms up to 550 square feet. With a cooling capacity of 12,000 BTU (ASHRAE) or 8,000 BTU (DOE), it can effectively cool medium to large-sized rooms. Additionally, it features a heating capacity of 9,000 BTU, making it useful in both summer and winter. Its energy efficiency ratio (EER) is 5.8, which is decent but not the most energy-efficient option available. The noise level of 52 dB is relatively quiet, ensuring minimal disturbance during use.

The unit is designed for portability with dimensions of 16.5” x 11.7” x 27.9” and comes with wheels for easy movement between rooms. Besides cooling and heating, it also functions as a dehumidifier and fan, adding to its versatility. Smart control options include Wi-Fi connectivity, compatibility with Amazon Alexa and Google Assistant, and a 'Follow Me' remote for precise temperature management. The installation process is simplified with an included window kit.

However, it's important to note that the Seasonal Energy Efficiency Ratio (SEER) is on the lower side, and it is not Energy Star certified, which might result in higher energy consumption. Additionally, at 57.6 pounds, it might be a bit heavy for some users to move frequently. Maintenance involves a standard filter type, which is user-friendly. This unit is best suited for users looking for a multi-functional, smart-controlled air conditioner with heating options, though its energy efficiency could be a concern for those prioritizing lower energy bills.

The Whynter Portable Air Conditioner ARC-14S is a strong choice if you need to cool a medium to large room (up to 500 sq. ft.) with its powerful 14,000 BTU cooling capacity. It uses a dual-hose system, which generally provides better efficiency and faster cooling than single-hose models. The energy efficiency ratio (EER) of 7.69 is decent, though it doesn’t have an Energy Star rating, so it might use a bit more electricity compared to some other units. Noise levels are quite reasonable at 51 dB on low speed, making it suitable for bedrooms or living spaces where quiet operation matters. At 73 pounds and standing 35.5 inches tall, it’s not the most portable unit, so it’s more for semi-permanent setups rather than frequent moving.

One big plus is the built-in dehumidifier that can remove up to 71 pints of moisture daily, helping improve comfort in humid environments. It also features three operation modes—cooling, dehumidifying, and fan—with three fan speeds and full thermostat control, giving you flexible temperature management. Maintenance is fairly straightforward with washable pre-filters and activated carbon filters included, which help with air quality and are easy to clean. The unit comes with a window installation kit and remote control for convenience.

However, it consumes up to 1300 watts, so electricity costs could add up if used extensively. The size and weight might be a drawback if you want a truly portable unit for multiple rooms. This model is well suited for those looking for a powerful and quiet portable air conditioner with solid dehumidifying capabilities, especially if you have a larger room and don’t move your AC around frequently.
