10 Best Portable Air Conditioners 2025 in the United States

The SereneLife Small Air Conditioner Portable 12,000 BTU is a versatile unit that offers both cooling and heating functions, making it suitable for year-round use. With a cooling capacity of 12,000 BTU, it can effectively cool rooms up to 550 sq ft, making it ideal for bedrooms, living rooms, or even a garage. The built-in dehumidifier is a valuable feature for reducing humidity levels, adding to the comfort of your living space.

Its Energy Efficiency Ratio (EER) and Seasonal Energy Efficiency Ratio (SEER) are commendable, ensuring decent energy savings. The unit operates at a noise level of 56 dB, which is relatively quiet, but may still be noticeable in a silent room. It’s designed to be portable with rolling wheels, although its weight of 70.3 pounds might make it slightly cumbersome for frequent moving. The dimensions of 13.4 x 17.4 x 32.1 inches are fairly compact, making it easier to place in various rooms.

The programmable timer and remote control add to the convenience of setting and adjusting the unit’s functions without needing to get up. Additionally, the automatic swing mode maximizes air circulation throughout the room. The exhaust hose and window mount kit included facilitate straightforward installation. Those seeking a portable air conditioner with additional heating and dehumidification capabilities will likely find this product to be a good fit for their needs.

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.

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.
