10 Best Portable Ac Units 2025 in the United States

The BLACK+DECKER 10,000 BTU Portable Air Conditioner is designed for rooms up to 450 square feet, making it suitable for medium-sized bedrooms or living spaces. Its 10,000 BTU cooling power offers solid performance to keep your room comfortable during warm weather. It also has a 3-in-1 function, working as an air conditioner, dehumidifier, and fan, which adds versatility for different needs. The unit is fairly portable, weighing about 47 pounds and equipped with side handles and casters, so you can easily move it between rooms. Measuring roughly 15 by 24 inches, it won't take up too much floor space, though it's not the lightest model out there. Noise level is moderate at 52 dB—noticeable but not overly loud, so it shouldn’t disturb most people while sleeping or working.

With a Seasonal Energy Efficiency Ratio (SEER) of 6.7 and a 5-star Energy Star rating, it is fairly energy efficient, helping keep electricity costs reasonable. Ventilation comes via a large vented outlet and the package includes an easy-to-install window kit, simplifying setup. Additional convenient features include a remote control, top LED display, a washable air filter, auto water evaporation to reduce the need for manual draining, and a 24-hour timer to customize operation.

While the cooling capacity is good for medium rooms, it might struggle in larger spaces, and at nearly 50 pounds, it's not the lightest option if you plan to move it very often. The noise level might be a bit high for very quiet environments. This BLACK+DECKER model offers a solid combination of cooling power, energy efficiency, and useful extras, making it a good choice for those needing a reliable, moderately portable AC unit for medium-sized rooms.

The BLACK+DECKER 12,000 BTU Portable Air Conditioner is designed for cooling rooms up to 550 sq. ft., making it a suitable option for bedrooms, living rooms, or home offices. One standout feature is its 3-in-1 functionality, combining an air conditioner, dehumidifier, and fan, which adds versatility and convenience. The unit comes with a remote control that supports 'Follow Me' functionality, allowing more precise temperature control based on the location of the remote. Additionally, its casters and side handles make it easy to move around, enhancing its portability despite its 56.8 lbs weight. The included window kit simplifies installation, ensuring that users can set up the unit quickly without complicated procedures.

The Seasonal Energy Efficiency Ratio (SEER) of 5.8 indicates it is not the most energy-efficient model available, potentially leading to higher energy costs over time. The noise level of 52 dB is moderate, which means it could be noticeable but not overly disruptive during operation. The unit does lack Energy Star certification, suggesting it may not meet the highest standards for energy efficiency. In terms of size, its dimensions (13.8”D x 17.1”W x 28.1”H) are relatively compact, which is beneficial for tight spaces, although users should ensure they have adequate room for ventilation. The environmentally friendly R410a refrigerant is a plus, as it reflects a commitment to reducing environmental impact.

This portable air conditioner offers solid cooling performance and convenient features, but users should weigh its energy efficiency and noise level against their specific needs.

The SereneLife Small Air Conditioner Portable unit packs a 10,000 BTU cooling capacity, making it suitable for rooms up to 450 sq. ft. This unit is versatile with four modes - cooling, heating, dehumidifier, and fan - which means it can be used year-round. Its built-in dehumidifier is a useful feature for reducing humidity levels, and the remote control adds convenience for adjusting settings from a distance.

The unit's sleek design and rolling wheels make it easy to move around as needed, whether in a bedroom, living room, or office space. The noise level is relatively moderate at 52-56 dBa, making it quieter than many other models on the market, which is beneficial for light sleepers or work environments. Additionally, the unit comes with a window mount exhaust kit for straightforward installation.

One of the notable features is its high SEER value of 29.7, indicating excellent energy efficiency, which can save on electricity bills over time. On the downside, it weighs 56.5 pounds, which might be cumbersome for some users to move around frequently. Moreover, its cooling power is rated at 6,000 BTU (SACC), so it may not be as efficient in extremely hot climates. While it covers up to 450 sq. ft., it might struggle in larger open spaces. Nonetheless, it holds strong customer ratings and seems to be a popular choice among portable air conditioners. Those seeking a versatile, energy-efficient, and moderately quiet portable AC unit for small to medium-sized rooms would find this model beneficial.
