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 Smart Portable Air Conditioner delivers solid cooling performance with its 14,000 BTU capacity, suitable for rooms up to 700 square feet. It smartly combines three functions—cooling, dehumidifying, and fan mode—which is convenient if you want a multi-use device in one. The noise level is moderate at 54 decibels, so it’s not whisper-quiet but should be acceptable for most living spaces and bedrooms without causing disturbance. Portability is decent: while it’s not very light at about 62 pounds, it comes with an easy-to-install window kit and a compact size that allows moving it between rooms if needed. The unit scores a SEER rating of 6.2, which is fairly average for energy efficiency, so expect reasonable power consumption but not the most efficient on the market.

A standout feature is its smart capabilities, including Wi-Fi control via a mobile app and compatibility with voice assistants like Alexa and Google Assistant, making it easy to operate remotely. The included 'Follow Me' remote adds extra comfort by using the remote as a thermostat to maintain precise temperature where you are. However, it lacks a programmable timer, which some users might miss for scheduling cooling periods automatically. The washable filter is a plus for maintenance, helping keep the air cleaner without extra costs.

This BLACK+DECKER unit is a strong choice if you want a versatile, smart portable AC with decent cooling and dehumidifying features, suitable for medium to large rooms. It offers a good balance of functionality and convenience, though if you need ultra-quiet operation or top energy savings, you might want to explore other alternatives.

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.
