10 Best In Room Air Conditioner No Exhaust 2026 in the United States

The BLACK+DECKER 10,000 BTU portable air conditioner is a solid choice for cooling rooms up to about 450 square feet. It offers a decent cooling capacity that should keep small to medium rooms comfortable during hot weather. With a 5-star Energy Star rating and a SEER of 6.7, it’s relatively energy-efficient, which helps save on electricity bills compared to less efficient units. The noise level at 52 dB is moderate—not too loud but noticeable, similar to a quiet conversation, so it’s generally suitable for bedrooms or living areas if you’re sensitive to sound.

One handy feature is its 3-in-1 functionality, working as an air conditioner, dehumidifier, and fan, making it versatile for different weather conditions. The remote control and LED display add convenience, and the washable filter and auto water evaporation system reduce maintenance hassle. Its portability is enhanced by side handles and casters, so moving it around the house is easy.

While it includes a window installation kit, this unit still requires venting to the outside to work efficiently, which might limit where you place it. The cooling power is ideal for rooms up to 450 sq. ft., so larger spaces may not get adequate cooling. This makes it a practical option if you want a portable, multi-use unit with good energy efficiency and manageable noise levels.

The BLACK+DECKER Portable Air Conditioner is a solid choice for cooling small to medium-sized rooms, up to about 450 square feet. Its 10,000 BTU cooling capacity is suitable for spaces like dorms, offices, or bedrooms, providing noticeable cooling down to 61°F on the lowest setting. It operates quietly at 52 decibels, which is about the noise level of a quiet conversation, so it won’t be disruptive during work or sleep.

Additionally, its 3-in-1 functionality—cooling, fan, and dehumidifying—adds versatility, helping reduce humidity without needing a separate device. The self-evaporating system means less hassle with water drainage, which is a user-friendly feature. Installation is straightforward, using a window adapter and hose to vent hot air outside, and it comes with a remote control and easy-to-read display for convenience.

While it is portable with wheels, the unit is fairly heavy at nearly 55 pounds, which might limit frequent moving. Its energy efficiency may be lower compared to more advanced models designed for energy savings. The unit includes a washable filter but requires regular cleaning to maintain performance. This BLACK+DECKER model serves as a practical, easy-to-use option for cooling smaller rooms with moderate noise and decent features, though those prioritizing energy efficiency or very quiet operation might consider other models.

The BLACK+DECKER 3-in-1 Personal Portable Air Conditioner offers a versatile cooling solution with its capability to function as an air conditioner, dehumidifier, and fan. With a compact design, it is well suited for personal use in small spaces like desks or bedside tables. With a cooling capacity of 1000 BTUs, it is not intended for cooling entire rooms or larger areas. This unit does not require a window installation, making it convenient for various setups.

It features dual exhaust hoses to direct warm air away and has adjustable speeds for both cooling and fanning, which provides some flexibility in its use. The noise level is relatively low at 48 dB, which is manageable for most indoor environments, but it may still be noticeable in very quiet settings. The energy efficiency of this unit isn't explicitly detailed, but considering its small size and specific use-case, it might not be the most energy-efficient option available.

Additional features include an electronic control panel, LED display, a timer, and casters for easy mobility. Weighing 28.6 pounds, it is reasonably portable but might be slightly cumbersome for frequent moving. This air conditioner is best suited for individuals looking for a portable, space-saving cooling solution for personal use rather than for cooling large rooms or spaces.
