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 BLACK+DECKER 12,000 BTU portable air conditioner is a solid choice for cooling rooms up to around 500-550 square feet. It operates at a fairly quiet 52 dB, making it suitable for bedrooms or living rooms without being too distracting. Its 12,000 BTU cooling power serves medium-sized rooms well, and it doubles as a dehumidifier and fan, providing versatile comfort options during warm months. Additional features include a remote control, a 24-hour programmable timer, and an auto water evaporation system, which reduces the need to empty water tanks frequently.

Portability is well addressed with side handles and smooth casters, allowing for easy movement between rooms. The included window installation kit simplifies setup. However, the unit’s weight of nearly 57 pounds might be a consideration if frequent relocation is required. The energy efficiency ratio (SEER) is moderate at 5.8, and since the unit is not Energy Star certified, it could consume more power compared to some newer models.

The washable filter helps maintain air quality while lowering maintenance costs. Although it is not the quietest model on the market, its noise level is acceptable for most home environments. The 1-year warranty is standard but might feel limited for extended use. For those seeking a reliable, moderately quiet portable AC with decent cooling power and useful features like remote control and dehumidification, the BLACK+DECKER BPACT12WT is a practical option, especially for medium-sized rooms. However, if energy efficiency or ultra-low noise levels are priorities, exploring other models could be beneficial.
