10 Best Quiet Portable Ac Units 2025 in the United States

The BLACK+DECKER 10,000 BTU Portable Air Conditioner is a solid choice for those looking to cool rooms up to 450 sq. ft. It offers a noise level of 52 dB, which is reasonably quiet for a portable unit, making it suitable for bedrooms or living spaces where you want to minimize disturbances. The 3-in-1 functionality as an air conditioner, dehumidifier, and fan adds versatility, allowing you to adjust to various comfort needs while helping to manage humidity levels effectively. Its cooling capacity of 10,000 BTU ensures efficient performance, especially during hot summer months.

Portability is another highlight, thanks to the built-in casters and handles, making it easy to move from room to room. The included installation kit simplifies the setup process, so you won’t be left sweating over complicated installations. Additionally, the remote control and programmable timer enhance user convenience, allowing you to adjust settings without getting up.

There are a few drawbacks to consider. While the noise level is relatively low, some users may still find it noticeable, especially during quiet nights. The energy efficiency ratio (EER) at 6.7 is decent, but there are more energy-efficient models available if you prioritize lower energy consumption. The unit's weight at 47.3 lbs may also be cumbersome for some users, despite its portability features.

The BLACK+DECKER 8,000 BTU Portable Air Conditioner is a strong contender for cooling rooms up to 350 sq. ft., suitable for bedrooms or small living spaces. One of its key strengths is the low noise level, rated at 54 dB, making it a quieter option compared to many other portable AC units. It offers 3-in-1 functionality, serving as an air conditioner, dehumidifier, and fan, which adds substantial versatility. The unit is equipped with a remote control and a top-mounted control panel with an LED display, enhancing user convenience.

The energy efficiency ratio (EER) of 5.4 is on the lower side, indicating it may consume more power compared to more energy-efficient models. However, it compensates with features like a 24-hour programmable timer and auto water evaporation, which can help manage energy use more effectively. Portability is another strength, with casters on the bottom and side handles making it easy to move between rooms. The included installation kit with a large vented airflow outlet simplifies setup.

Despite its weight of 52.9 pounds, the design ensures it's manageable. One potential drawback is its energy efficiency, which may lead to higher electricity bills if used frequently. Additionally, while it is powerful enough for its size, larger rooms might require a unit with higher BTU. The dehumidification function and washable filter add further value, making it a good choice for those needing both cooling and moisture control. In summary, the BLACK+DECKER 8,000 BTU Portable Air Conditioner combines quiet operation, portability, and multifunctionality, though its energy efficiency could be better.

The EUHOMY Portable Air Conditioner offers solid cooling power with an 8,000 BTU rating, effectively cooling rooms up to 350 square feet, making it a good choice for bedrooms, apartments, or small living spaces. It has a respectable Energy Efficiency Ratio (EER) of 6.1, helping to save energy costs while running. Noise-wise, it operates at about 52 decibels in sleep mode, which is fairly quiet and suitable for nighttime use without causing much disturbance. Portability is well addressed with its compact size, four smooth wheels, and built-in handles, so you can easily move it around your home.

Besides cooling, it works as a dehumidifier, removing up to 44 pints of moisture daily, which is useful in humid conditions, and it also offers a fan mode for gentle air circulation. The included remote control and 24-hour programmable timer add convenience, letting you adjust settings from across the room or schedule operation to save energy. Installation is simple with the adjustable window exhaust kit, though some window sizes may require cutting the kit to fit.

While 52 dB is quiet for a portable AC, it’s not the absolute quietest on the market, and at 40.8 pounds, it’s manageable but not the lightest for portability. Some users might find the need to use the remote for certain settings takes a bit of getting used to. This unit balances effective cooling, energy efficiency, and user-friendly features, making it a practical pick for those looking for a quiet, portable AC with added dehumidification.
