10 Best Ductless Portable Air Conditioner 2026 in the United States

The BLACK+DECKER Smart Portable Air Conditioner with Heat offers a versatile solution for year-round comfort with a cooling capacity of 12,000 BTU ASHRAE (8,000 BTU DOE) and heating capacity of 9,000 BTU. This unit can effectively cool or heat rooms up to 550 sq. ft., making it suitable for bedrooms and medium-sized spaces. Its portability is enhanced by a compact form factor and wheels, allowing for easy maneuvering between rooms. However, it weighs 57.6 pounds, which might be cumbersome for some users to move frequently.

The energy efficiency ratio (EER) is 5.8, which is not the highest, meaning it may not be the most energy-efficient option available on the market. The noise level is 52 dB, which is relatively quiet but might still be noticeable in a quiet room. The unit includes a smart control feature that allows for Wi-Fi connectivity and voice control via Amazon Alexa and Google Assistant, adding convenience for tech-savvy users. The Follow Me Remote feature ensures precise temperature control by acting as a thermostat.

Maintenance is straightforward with the dehumidifier function and easy-to-install window kit included. The unit is not Energy Star rated, which might be a consideration for those looking to save on energy costs. The lack of an Energy Star rating and moderate EER are potential drawbacks for cost-conscious consumers.

The BLACK+DECKER Smart Portable Air Conditioner with Heat is a versatile and powerful unit designed for rooms up to 700 sq. ft. It offers a good cooling capacity of 14,000 BTU (ASHRAE) and 10,000 BTU (DOE), along with a heating function of 12,000 BTU, making it suitable for use throughout the year.

The energy efficiency ratio (EER) is not specified, but the SEER of 6.2 indicates moderate energy efficiency. With a noise level of 54 dB, it operates relatively quietly, making it a good option for bedrooms and living rooms. It includes smart features like Wi-Fi connectivity and voice control through Amazon Alexa or Google Assistant, which add to its convenience.

The Follow Me remote control is a standout feature, allowing for more precise temperature control. Portability is ensured with its compact dimensions and included window installation kit, making it easy to set up and move as needed. However, it's important to note that it is not Energy Star rated, which may be a consideration for those looking for highly energy-efficient models. This unit is well-suited for those seeking a multi-functional portable air conditioner and heater with smart features and reliable performance, particularly in mid-sized to larger rooms.

The BLACK+DECKER Smart Portable Air Conditioner delivers a solid cooling capacity of 14,000 BTU (10,200 BTU SACC), making it suitable for rooms up to 700 square feet — ideal for bedrooms and living areas. Its energy efficiency ratio (EER) is about 6.2, which is average for portable units; it won’t save a huge amount on electric bills but performs reasonably well for its size. Noise is moderate at 52 decibels, so it might be noticeable but generally won’t disturb most daily activities or sleep.

Portability is decent for a unit of this power; it weighs around 68 pounds and comes with a window installation kit, making it somewhat easy to move and set up without professional help. The inclusion of a washable filter is a plus, as it keeps maintenance simple and cost-effective. Control options are a strong point here. You get a full-function remote with a clever 'Follow Me' feature that uses the remote as a thermostat for more precise temperature control. Plus, it connects via Wi-Fi for app control and supports voice commands through Amazon Alexa and Google Assistant—features usually seen on more expensive models.

On the downside, the unit is fairly large and might be bulky for tight spaces. Also, it lacks inverter technology, so it may consume more energy during operation compared to newer, more efficient models. The warranty covers just one year, which is typical but worth noting. This BLACK+DECKER model suits users looking for a reliable, smart, and fairly powerful portable AC for medium to large rooms. It is especially attractive if you value smart controls and easy maintenance, though it may not be the quietest or most energy-efficient option available.
