10 Best Air Conditioners Air Conditioners 2025 in the United States

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 Daikin 24,000 BTU Dual Zone Mini Split Air Conditioner is a strong choice if you need efficient cooling and heating across two separate rooms or zones. It offers a solid cooling capacity of about 23,000 BTU with a high energy efficiency rating (SEER 21), meaning it uses power smartly to keep energy bills down. The system uses the eco-friendly R-32 refrigerant and provides reliable heating even in cold conditions, giving you all-season comfort. Noise-wise, it’s impressively quiet at just 24 dB, so it won’t disturb your peace at home. Being a ductless mini split, it’s ideal for spaces where installing traditional ductwork is difficult, such as sunrooms or basements.

The unit includes two indoor fan coils with independent controls, allowing personalized temperature settings for each zone, which is great for families or multi-room setups. Additional features include Wi-Fi control through an app, voice command support with Alexa and Google, and air cleaning with a Titanium filter, enhancing convenience and air quality. On the downside, while the system is energy efficient, it is not Energy Star certified, which some users look for as a sign of top-tier efficiency. Also, installation requires professional setup and comes with included kits, so it’s not a simple DIY project.

The price point might be higher than window units or single-zone systems, reflecting its advanced features and multi-zone capabilities. If you want a quiet, energy-efficient solution that offers flexible control and heating/cooling throughout multiple areas, this Daikin mini split is an excellent choice.

The Daikin 18,000 BTU Multi-Zone Mini Split is designed to cool and heat two separate rooms independently, making it a great choice if you want personalized comfort in different areas of your home. Its cooling capacity of 18,000 BTU (split as 9,000 BTU per zone) is suitable for spaces around 800 square feet, which fits well for medium-sized rooms or combined smaller rooms. The unit stands out with high energy efficiency, boasting a 21 SEER2 rating and using the eco-friendly R-32 refrigerant, which helps save on electricity while being better for the environment. Noise level is impressively low at just 24 decibels, so it operates quietly without disturbing your daily activities or sleep.

This system uses an inverter compressor, which adjusts power smoothly for both cooling and heating, improving comfort and efficiency throughout the year. Additional features like Wi-Fi control via an app or voice commands, air purification with a titanium filter, and automatic functions for humidity and diagnostics make it convenient and user-friendly. Installation kits and wall brackets are included for easier setup.

A notable point is that it is not Energy Star rated, so some other models might offer higher official energy certifications. Also, being a split system, professional installation is required, which can add to the cost. While it covers moderate cooling and heating needs well, very large homes or multiple bigger rooms might require a more powerful or additional unit. If you want a quiet, efficient, and flexible air conditioner that provides year-round comfort for two rooms without ductwork, this Daikin mini split is a solid option.
