10 Best Quiet Portable Ac Units 2025 in the United States

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.

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 Dreo Portable Air Conditioner is a notable choice for those seeking a quiet and efficient cooling solution. With a cooling capacity of 12,000 BTU, it is powerful enough to cool spaces up to 300 square feet, making it suitable for bedrooms or small offices. A standout feature is its noise level; at just 46 dB, it operates quietly, which is ideal for environments where silence is valued. The unit is designed to be drainage-free in environments with humidity levels under 85%, reducing the hassle of continuous water removal.

This model also offers impressive smart features, including compatibility with Alexa and Google Assistant, and control via a mobile app, allowing for convenient operation. The inclusion of a 24-hour programmable timer further enhances its usability. However, the unit's Seasonal Energy Efficiency Ratio (SEER) of 6.1 suggests it may not be the most energy-efficient option available, which could lead to higher energy consumption over time.

Portability is facilitated by a universal window kit that accommodates various window sizes, though its weight of nearly 63 pounds might make it less easy to move frequently. The 3-in-1 functionality, combining cooling, fan, and dehumidification modes, offers versatility in different climate conditions. In conclusion, the Dreo Portable Air Conditioner is a robust and quiet unit with advanced smart features, perfect for users wanting convenience and efficient cooling. Potential buyers should weigh its energy use against these benefits, especially if energy consumption is a primary concern. The strong customer service and warranty provided by Dreo add additional reassurance for long-term use.
