10 Best Air Conditioners 2025 in the United States

The BLACK+DECKER Smart Portable Air Conditioner with Heat offers a solid cooling capacity of 14,000 BTU ASHRAE (10,000 BTU DOE), which is suitable for rooms up to 700 sq. ft. This makes it a good fit for medium to large-sized rooms. Additionally, it has a 12,000 BTU heating capacity, allowing it to be used year-round. The unit functions as a dehumidifier and fan, adding to its versatility.

The energy efficiency ratio (SEER) of 6.2 is relatively low, indicating higher energy consumption compared to more efficient models. It's important to note that this model is not Energy Star rated, which means it might not be the most cost-effective option over time for energy savings. The noise level is 54 dB, which is moderate and may be noticeable in quieter environments but should be acceptable for most users. The air conditioner is portable, making it easy to move around as needed.

Additional features include smart connectivity with Wi-Fi, app control, and voice commands via Amazon Alexa or Google Assistant, which add convenience. The 'Follow Me' remote control is another useful feature, allowing for more precise temperature control. The product includes an easy-to-install window kit for setup. Weighing 35 pounds and having compact dimensions, it should be manageable for most people to handle. Assembly is required, which might be a minor inconvenience for some users. This BLACK+DECKER unit is a versatile and convenient option, especially for those looking for a portable and smart-controlled air conditioner with heating capabilities, despite its higher energy consumption.

The BLACK+DECKER Smart Portable Air Conditioner is a solid choice for cooling rooms up to 700 square feet, thanks to its 14,000 BTU cooling capacity. This makes it suitable for medium to large bedrooms or living areas. It offers a three-in-one design, working as an air conditioner, dehumidifier, and fan, which adds versatility for different weather conditions. The unit includes a washable filter and uses the environmentally friendly R-32 refrigerant.

Energy efficiency is moderate, with a SEER rating of 6.2, which means it won’t be the cheapest to run but performs reasonably well compared to similar models. Noise level sits at 54 dB, which is about as loud as a normal conversation—noticeable but not overly disruptive, so it can work well in bedrooms or offices. A strong point is the smart features: you can control this AC via an app or voice commands through Alexa and Google Assistant, which is handy for convenient temperature adjustments. The "Follow Me" remote acts as a mobile thermostat, helping maintain more precise comfort where you actually are in the room.

Installation is user-friendly with an included window kit and exhaust hose, meaning you can set it up without professional help. The unit is portable, though it weighs over 60 pounds, so moving it around frequently might be a bit cumbersome. One drawback is that while the advertised cooling capacity is 14,000 BTU ASHRAE, the effective cooling (SACC) is 10,200 BTU, which is important to note for very hot climates or larger spaces. Additionally, the 1-year limited warranty is standard but somewhat short, so consider this if long-term durability is a priority. This BLACK+DECKER portable AC suits users needing smart, flexible cooling for medium-sized rooms, combining decent power with helpful modern features. It might not be the quietest or most energy-efficient option, but its ease of use and versatility make it a practical choice for many.

The Midea 8,000 BTU Smart Inverter Window Air Conditioner is a solid choice for cooling and heating rooms up to 350 square feet. Its inverter technology helps it cool efficiently while using less energy, which is supported by its Energy Star rating and a high SEER of 14.5. This means it can save you money on electricity compared to standard units. It’s also quieter than many air conditioners, operating at about 45 decibels, so it won’t disturb your work, TV time, or sleep. The unit includes multiple modes like heat, cool, dry, fan, and auto, plus three fan speeds, making it adaptable to different comfort needs. You can control it via LED panel, remote, smartphone app, or even voice commands through Alexa or Google Assistant, which adds convenience.

The built-in heat pump is a nice bonus for cooler months but works best when outdoor temperatures are above 41°F. Installation fits standard double-hung windows with specific size requirements, so measuring your window beforehand is important. The heating function’s limitation in colder climates might restrict its usefulness year-round if you live somewhere very cold. Also, while energy efficient, its 8,000 BTU capacity is best suited for medium-sized rooms rather than larger spaces. The washable filter is easy to maintain, but the unit’s weight (56 pounds) might require two people for installation. If you want a versatile, quiet, and energy-saving window air conditioner that also heats, this Midea model covers those bases well.
