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.

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 Frigidaire 5,000 BTU Window Air Conditioner is designed for small spaces up to 150 square feet, making it a good fit for bedrooms, offices, or compact rooms.

The unit operates quietly at 52 decibels, so it won’t be disruptive, which is great if you’re sensitive to noise while sleeping or working.

Energy-wise, it offers Eco and Sleep modes that help reduce electricity use, though it’s not Energy Star certified, so it might not be the most efficient choice compared to some other models. It comes with convenient features like a remote control, a washable dust filter with a cleaning reminder, a 24-hour timer, and a dry mode to reduce indoor moisture. The 6-way directional airflow and three fan speeds let you customize the cooling direction and intensity. Installation is typical for a window unit, and the included window kit should simplify setup.

With a straightforward design and useful features for comfort and ease of use, the cooling power limits it to smaller rooms and it might not be the best fit if you need to cool larger spaces. The one-year warranty offers basic protection, and customer reviews indicate good reliability and satisfaction. This unit serves as a solid, quiet, and user-friendly option for cooling small areas without heavy energy costs.
