10 Best Portable Air Conditioners 2025 in the United States

The BLACK+DECKER Smart Portable Air Conditioner is a versatile unit with a solid cooling capacity of 14,000 BTU, making it suitable for rooms up to 700 square feet. It also doubles as a heater (up to 10,000 BTU), which is handy for year-round use. The device includes a dehumidifier and fan, adding to its functionality beyond just cooling. Its noise level is about 54 dB, which is moderate and might be noticeable but not overly disruptive in most home settings. The unit is somewhat large and weighs around 60 pounds, so while it's portable, it might not be the easiest to move frequently without some effort. It comes with an installation kit for window venting, simplifying setup.

Energy efficiency is average (SEER 6.2), and this model isn’t Energy Star certified, so it may use more power compared to more efficient options. The smart features, including Wi-Fi connectivity and voice control with Alexa or Google Assistant, add convenience, and the Follow Me remote is a neat feature that helps maintain precise temperature by using the remote as a thermostat. Programmable timer and full remote control improve user-friendliness. However, the water capacity for dehumidification is limited (0.8 liters), meaning you might need to empty it relatively often in very humid conditions. The lack of Energy Star rating and moderate noise level might be drawbacks for users prioritizing low energy consumption and quieter operation.

With a one-year warranty and positive customer ratings, this product represents a dependable choice for those needing a multi-function portable AC that covers both cooling and heating, suitable for medium to large rooms.

The Midea Duo 14,000 BTU portable air conditioner is designed to cool spaces up to 550 sq. ft. efficiently. One of its standout features is the innovative duo hose design, which helps in maintaining balanced air circulation and prevents hot air from seeping indoors, making it suitable for larger rooms. With a cooling capacity of 14,000 BTU, this unit promises fast and strong cooling, while the variable-speed inverter technology ensures it operates with 40% less energy than standard models, making it an energy-efficient choice.

Measuring 16.73 x 19.53 x 34.48 inches, it is relatively portable for its capacity. Additionally, it offers a dehumidification function, removing up to 58.99 liters of moisture daily, which is beneficial for humid climates. The noise level is impressively low at 42 dB, ensuring quiet operation, ideal for sleeping or working environments. Users can control the unit via a remote, smartphone app, or voice commands using Alexa or Google Assistant.

However, despite its high efficiency and advanced features, the installation might require careful setup to ensure the hose-in-hose system works effectively. The unit is also slightly larger and heavier, which might pose a challenge for moving between rooms frequently. This portable air conditioner is well-suited for users looking for a powerful, quiet, and energy-efficient cooling solution with smart features.

The SereneLife 14000 BTU portable air conditioner is a strong choice for cooling larger rooms up to about 650 square feet, making it well suited for bedrooms, living spaces, and offices. Its inverter technology helps deliver faster cooling while being up to 40% more energy efficient than typical portable AC motors, which can save on electricity bills. It also offers heating, fan, and dehumidifying modes, allowing you to use it year-round.

The unit is relatively compact and comes with casters, so it can be moved around with moderate effort, although it weighs about 53 pounds, which might be a bit heavy for some. Noise level is about 53 decibels, which is a bit louder than the 43 dBA claimed for quieter operation but still acceptable for most living areas. Installation is straightforward with the included window mounting kit, and maintenance is easier thanks to a washable air filter.

The AC includes convenient extras like a remote control and WiFi for smart operation. While it has good energy efficiency, the noise could be noticeable in very quiet rooms, and the unit's size is slightly bigger than smaller portable units. This makes it a solid pick if you want a powerful, energy-conscious portable AC that cools large rooms and works throughout the year, but be prepared for some noise and effort when moving it.
