10 Best Portable Air Conditioner 2026 in the United States

The BLACK+DECKER Smart Portable Air Conditioner is a solid choice for cooling rooms up to 700 sq. ft. With 14,000 BTU ASHRAE (10,000 BTU DOE), it offers substantial cooling power, making it suitable for larger spaces. Its portable design (16.5” x 14.06” x 27.09”) makes it easy to move around, though it's on the heavier side at 62.4 pounds. The SEER of 6.2 indicates decent energy efficiency, though not the best in its class. The noise level of 54 dB is relatively moderate, meaning it won't be too disruptive in most settings.

One of its standout features is the 'Follow Me' remote, which acts as a thermostat for more precise temperature control. Additionally, the smart capabilities, including Wi-Fi connectivity and voice control via Amazon Alexa or Google Assistant, provide modern, hands-free convenience. The included installation kit makes setup straightforward, though some users might find the included window kit a bit cumbersome.

The unit also functions as a dehumidifier and a fan, adding to its versatility. The washable filter is a practical feature for easy maintenance. However, some users might find the need for occasional manual water drainage due to its dehumidifying function an extra task. It’s an excellent option for those looking for a smart, multi-functional, and powerful portable air conditioner, though it may not be the quietest or most energy-efficient option available.

The Whynter ARC-1230WNH is a versatile portable air conditioner that cools, heats, dehumidifies, and fans spaces up to 600 square feet. With a powerful 14,000 BTU rating (12,000 BTU SACC), it’s well-suited for medium to large rooms. Its dual-hose inverter technology boosts cooling efficiency by around 20% and makes it 40% more energy-efficient than traditional models, which is a real plus for saving on electricity without sacrificing performance. The unit operates quietly at about 42.5 decibels, so it won’t disturb your daily activities or sleep. Size-wise, it’s somewhat bulky at over 77 pounds and about 32 inches tall, so while portable, it might require some effort to move around and a suitable spot near a window for venting.

The dual-hose system helps with better air intake and exhaust, improving cooling speed and stability. Installation accessories and a washable air filter are included, which is convenient. One standout feature is its smart Wi-Fi connectivity that lets you control the unit remotely via an app or voice assistants like Alexa and Google Home, adding modern ease to its use. It also offers flexible operation modes (cool, heat, dehumidify, fan) with adjustable fan speeds and thermostat control, making it useful year-round.

On the downside, it lacks an Energy Star rating, so it might not be the most eco-friendly option out there. The 1-year warranty is standard but a bit limited compared to some competitors. This Whynter model is ideal for those seeking a strong, quiet, and smart portable AC with heating and dehumidifying options, especially in larger rooms, but users should be aware of its size and moderate energy efficiency.
