10 Best Portable Room Air Conditioners 2025 in the United States

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 DOMANKI 14,000 BTU Portable Air Conditioner is a solid option for cooling spaces up to 700 square feet, making it suitable for large rooms, campervans, offices, and temporary spaces. Its high cooling capacity combined with the R32 refrigerant ensures efficient cooling. The unit operates at a noise level of 52 dB, which is relatively quiet, and even quieter in sleep mode at 48 dB, providing a comfortable environment without much disruption.

The portability is enhanced by its compact design and caster wheels, making it easy to move around as needed. Another key feature is its dehumidification function, which helps in maintaining optimal indoor air quality by removing excess moisture from the air. The programmable timer and thermostat offer convenience in setting the desired temperature and operation schedule, and the inclusion of a remote control ensures easy adjustments from a distance.

Maintenance is straightforward with a removable and washable filter, although the filter type is basic, which might not offer advanced air purification. The installation kit provided makes setup relatively simple for vertical and horizontal sliding windows. However, at 73.8 pounds, it might be slightly heavy for some users to maneuver. This air conditioner is ideal for those looking for a versatile and efficient cooling solution with additional features like child lock and multiple fan speeds, but might not be the best fit for users prioritizing advanced air filtration or extremely lightweight portability.

The BLACK+DECKER Portable Air Conditioner is a versatile unit with a cooling capacity of 10,000 BTU ASHRAE (6,300 BTU DOE), suitable for rooms up to 450 sq. ft. It combines air conditioning, dehumidification, and fan functions, making it a multifunctional appliance. The 'Follow Me' remote control feature is a strong point, allowing the remote to act as a thermostat for better temperature control, which can be very convenient for users seeking precise cooling without adjusting the unit manually.

With a noise level of 52 dB, it is relatively quiet, ensuring a peaceful environment, especially useful in bedrooms or offices. The unit's mobility is enhanced by casters and side handles, enabling easy transfer between rooms. Additionally, it comes with an easy-to-install window kit, simplifying the setup process.

However, the energy efficiency ratio (EER) of 6.7 indicates it is not the most energy-efficient model available, potentially leading to higher electricity consumption. While the dehumidification feature is beneficial, the capacity is modest at 0.45 liters, meaning it may require more frequent emptying in humid conditions. This BLACK+DECKER model stands out for its multifunctionality, ease of use, and mobility, though it may not be the best choice for those prioritizing energy efficiency.
