10 Best Air Conditioners Air Conditioners 2026 in the United States

The Hisense 8,000 BTU portable air conditioner is designed to cool rooms up to about 350 square feet, making it a good choice for bedrooms or small living rooms. Its dual-hose system helps cool the space more quickly and keep the temperature steady, which is better than single-hose models. Thanks to inverter technology, it uses energy more efficiently, potentially saving you money on electricity bills compared to traditional portable ACs. Noise-wise, it runs quietly at 42 decibels, low enough to allow comfortable sleep or work without distraction.

This unit offers three modes: cooling, dehumidifying, and fan-only, letting you adapt to different weather conditions. You also get smart features like Wi-Fi connectivity and compatibility with Google Assistant and Alexa for convenient control through an app or voice commands. Setup is straightforward with the included window kit and hardware. On the downside, the cooling capacity of 8,000 BTU means it’s not suitable for larger rooms or very hot climates. Also, it comes with only a limited 90-day warranty, which might be shorter than some users expect.

While the weight and size are typical for dual-hose portable units, it may be less easy to move around frequently compared to lighter models. This Hisense portable AC provides efficient, quiet cooling with useful smart features, making it a good fit for moderate-sized rooms and users who value energy savings and flexible control.

The BLACK+DECKER Smart Portable Air Conditioner with Heat is a versatile unit designed for rooms up to 700 sq. ft. Its cooling capacity is notable at 14,000 BTU ASHRAE (10,000 BTU DOE), making it suitable for large spaces. Additionally, it offers 12,000 BTU heating, which is great for year-round use. The unit stands out with its four-in-one functionality: air conditioning, heating, dehumidifying, and fan modes.

The Energy Efficiency Ratio (EER) is relatively low at 6.2, suggesting that it may not be the most energy-efficient option available. This could lead to higher electricity bills over time, particularly with regular use. Noise levels are at a moderate 54 dB, which is comparable to a quiet conversation; this should be manageable for most users, but noise-sensitive individuals may want to take note. The portability of this unit is a significant advantage, allowing users to move it easily between rooms.

The smart features, including Wi-Fi connectivity and compatibility with Amazon Alexa and Google Assistant, offer convenient control options. The 'Follow Me' remote control enhances user experience by allowing precise temperature settings. An included installation kit simplifies the setup process, making it user-friendly. Weighing 35 pounds, it is reasonably easy to handle but might require some effort to move frequently. This BLACK+DECKER model is best suited for those looking for a multi-functional, portable air conditioning solution with smart features and who are less concerned about energy efficiency.

The BLACK+DECKER Smart Portable Air Conditioner packs a strong 14,000 BTU cooling capacity, making it suitable for cooling rooms up to about 700 square feet, such as bedrooms or living rooms. It’s a portable unit, so it can be moved around easily without the need for permanent installation, which is great for renters or anyone wanting flexibility. It offers three functions in one unit: cooling, fan, and dehumidifier, helping to improve air comfort in different ways. The unit operates at a noise level of 52 decibels, which is reasonably quiet but might still be noticeable in very quiet rooms, especially at night.

On energy efficiency, it has an EER (Energy Efficiency Ratio) of 6.2, which is moderate—there are more efficient models out there, but this is typical for portable ACs. A standout feature is its smart connectivity: you can control it via a mobile app or voice commands through Alexa or Google Assistant, plus the remote has a “Follow Me” mode that uses the remote as a thermostat for more precise temperature control. Installation is user-friendly with the included window kit and exhaust hose. However, it does not have an inverter compressor, which means it might use more power during operation compared to inverter models that adjust cooling speed for efficiency.

The unit is also a bit heavy at over 68 pounds, so while portable, it may require some effort to move. It uses environmentally friendly R-32 refrigerant, which is a positive for reducing environmental impact. This BLACK+DECKER model serves as a solid choice for those needing a portable air conditioner with smart features and good cooling power for medium-sized rooms, but if you prioritize very low noise or highest energy savings, you might want to explore other options.
