10 Best Se Portable Ac Units 2026 in the United States

The Dreo Portable Air Conditioner offers a solid cooling capacity of 8000 BTU (ASHRAE rating) but effectively 5000 BTU DOE, making it suitable for small to medium bedrooms up to about 150 square feet. Its energy efficiency is decent with a SEER of 6.1, which should keep running costs reasonable for this type of unit. One of the standout features is its very quiet operation at 45 dB, thanks to Dreo’s patented noise isolation system, making it a good choice for bedrooms or workspaces where low noise is important.

The unit is fairly portable with smooth caster wheels and fits a wide range of window sizes using modular panels, though at about 25 inches tall and weighing 55 pounds, it’s not the lightest model around. Installation includes an exhaust hose that needs window ventilation, which is typical but something to plan for. The drainage-free system is convenient since it automatically evaporates moisture, eliminating the hassle of manual drainage in most humid conditions.

Additional smart features include app and voice control compatibility (Siri, Alexa, Google Assistant), customizable temperature and humidity settings, and a sleep curve function that can enhance comfort during the night. The cooling power may be limited for larger rooms or very hot climates, and while the noise level is low, it’s not completely silent. Also, some users might find the 59-inch exhaust hose a bit short depending on their window setup. The Dreo AC318S is a versatile and user-friendly portable AC that fits well in small bedrooms or personal spaces where quiet operation and smart features are valued.

The Midea 14,000 BTU portable air conditioner is designed to cool rooms up to 450 square feet, making it a solid choice for medium-sized spaces such as bedrooms, offices, or small living rooms. It offers a decent cooling capacity with a Seasonal Energy Efficiency Ratio (SEER) of 7.9, which means it balances cooling power with reasonable energy usage, though it’s not the most efficient unit on the market. Noise-wise, it runs at about 51.5 decibels, roughly equivalent to a quiet conversation, so it should be comfortable for most home environments without being too disruptive.

Portability is decent but not ultra-light—the unit weighs nearly 70 pounds and measures about 28.7 inches tall, so while it can be moved room to room, it might require some effort or a helper. Installation is beginner-friendly, with all necessary window kits and an exhaust hose included, meaning no extra tools are needed. However, it does require a window for proper ventilation, which is typical for portable ACs.

Smart features add convenience: you can control it via a remote, a smartphone app, or even voice commands through Alexa or Google Assistant. This makes adjusting settings easy whether you’re at home or away. Plus, it has additional modes like a fan and dehumidifier, which add versatility beyond just cooling.

The cooling capacity is rated at 14,000 BTUs ASHRAE but about 10,000 BTUs in SACC terms, which is the more realistic measure, so it may struggle in very hot or larger spaces. The energy efficiency is moderate rather than high-end, so expect average electricity use. Also, the noise level, while reasonable, may be noticeable in very quiet environments. Lastly, with nearly 70 pounds, it’s not the most compact or lightweight model available.

This Midea portable AC provides a user-friendly, moderately powerful solution suitable for those needing smart controls and flexibility in medium-sized rooms. It fits well if you want easy setup and smart features, though if ultra-quiet operation or top-tier efficiency is your priority, other options may be preferable.

The SereneLife Small Air Conditioner Portable 10,000 BTU is designed for rooms up to 450 sq ft, making it suitable for bedrooms, living rooms, or offices. Its compact size, rolling wheels, and lightweight design make it highly portable, while the included remote control offers convenient operation.

This unit features a built-in dehumidifier, which not only cools the air but also reduces humidity levels, saving both space and money. It has four operating modes—cooling, heating, dehumidifying, and fan—making it versatile for year-round use. The noise level ranges from 52 to 56 decibels, which is relatively quiet for a portable AC unit.

Additionally, it has a Seasonal Energy Efficiency Ratio (SEER) of 29.7, indicating good energy efficiency. However, the ventilation requirements could be a drawback for some users, as it requires a window mount exhaust kit. Also, while the cooling capacity is advertised at 10,000 BTU (ASHRAE) / 6,000 BTU (SACC), some users may find the actual performance slightly lower than expected. With a 1-year warranty, this unit offers a good balance of features and performance. It is particularly beneficial for those who need a portable and multifunctional AC unit for medium-sized rooms.
