10 Best Ductless Portable Air Conditioner 2025 in the United States

The BLACK+DECKER Portable Air Conditioner offers a cooling capacity of 10,000 BTU (ASHRAE 128), which translates to 6,300 BTU under DOE standards, making it suitable for rooms up to 450 sq. ft. This unit is versatile with its three-in-one functionality as an air conditioner, dehumidifier, and fan, catering to various needs beyond just cooling.

The Follow Me remote control is a standout feature, allowing precise temperature control by using the remote as a thermostat. Portability is another strength, thanks to the casters and side handles, which make moving the unit between rooms easy. The included window kit simplifies installation, ensuring a hassle-free setup.

The noise level of 52 dB might be noticeable, especially during the night in a bedroom setting. Its Energy Efficiency Ratio (EER) at 6.7 is relatively low, meaning it may not be the most energy-efficient option available. Maintenance involves managing a dehumidification process. This unit would be most beneficial for users looking for a multi-functional, easily movable air conditioner for medium-sized rooms, who can trade-off a bit on energy efficiency and noise levels.

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 12,000 BTU Portable Air Conditioner is designed to cool rooms up to about 550 square feet, making it a solid choice for bedrooms or medium-sized living spaces. It offers a decent cooling capacity at 12,000 BTU (although the official DOE rating is 7,000 BTU), which means it can handle typical summer heat effectively. The unit operates at a noise level of 52 dB, which is relatively quiet but might still be noticeable during very quiet moments like sleep. One thing to note is its Energy Efficiency Ratio (EER) of 5.8, which is on the lower side, so it may consume more electricity compared to more efficient models, and it lacks an Energy Star rating.

Portability is a strong suit here — the unit includes casters and side handles, so moving it between rooms is fairly easy despite its 56.8-pound weight. You also get a handy remote control and a top-mounted LED display for easy temperature adjustments, along with a 24-hour timer and a 'Follow Me' feature that adjusts cooling based on the remote’s location. Maintenance is user-friendly, with a slide-out washable filter and an auto water evaporation system that reduces the need to manually empty water. The included window installation kit is straightforward, allowing quick setup without professional help.

This BLACK+DECKER model balances good cooling power with convenient portability and simple controls. It suits someone who wants a reliable, easy-to-move air conditioner for a medium room without extra complexity or premium energy savings.
