10 Best Se Portable Ac Units 2026 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. It offers both cooling and heating capabilities, making it suitable for year-round use. With a 14,000 BTU ASHRAE (10,000 BTU DOE) cooling capacity and 12,000 BTU heating capacity, it can handle a variety of temperature conditions effectively. One of its notable features is the 'Follow Me' remote control, which acts as a thermostat for more precise climate control. Additionally, its smart connectivity allows it to be controlled via a mobile app or voice commands using Amazon Alexa or Google Assistant. This can be particularly convenient for tech-savvy users who enjoy smart home integration.

In terms of energy efficiency, the unit has a SEER of 6.2, which is relatively low and may result in higher energy consumption compared to more efficient models. It operates at a noise level of 54 dB, which is moderate and should be bearable for most users, though it may still be noticeable in quieter environments. The unit is quite portable, weighing 35 pounds and measuring 16.5” x 14.06” x 27.09”, which makes it easy to move from room to room. The included installation kit simplifies the setup process, ensuring that users can start using the unit quickly.

This model is not Energy Star rated, which might be a downside for those particularly concerned about energy efficiency. Also, while it's highly ranked and has many positive reviews, some users might find the noise level a bit disruptive in extremely quiet spaces. The BLACK+DECKER Smart Portable Air Conditioner with Heat is a solid choice for those looking for a multi-functional, tech-friendly AC unit, though it could be more energy-efficient.

The BLACK+DECKER Smart Portable Air Conditioner offers a strong cooling capacity of 14,000 BTU, making it suitable for cooling rooms up to 700 square feet, which fits well for medium to large rooms. It also works as a dehumidifier and a fan, giving you versatile comfort options beyond just cooling. With a SEER (Seasonal Energy Efficiency Ratio) of 6.2, its energy efficiency is moderate, so it won't be the cheapest on your electricity bill but not overly costly either.

Noise is a consideration here; at 54 decibels, it's somewhat noticeable, roughly like a normal conversation, which could be a bit distracting for very quiet settings like bedrooms at night. The unit is fairly portable for its size and power, measuring about 16.5 x 14 x 27 inches and weighing 62.4 pounds—manageable if you need to move it between rooms but not super light. Installation is straightforward with the included window kit and exhaust hose, designed for typical window setups, though proper ventilation is necessary as with all portable ACs. A standout feature is its smart capabilities: you can control it via a mobile app or voice commands with Alexa and Google Assistant, plus the Follow Me remote acts like a thermostat, improving temperature accuracy where you are in the room. The washable filter is a plus for maintenance and longevity.

The cooling capacity stated as ASHRAE (14,000 BTU) versus the lower SACC rating (10,200 BTU) indicates real-world cooling might be less than the headline number suggests, which is common in portable units but worth knowing. Also, the 1-year warranty is somewhat short compared to some competitors. This BLACK+DECKER model is a solid choice if you want a smart, multi-purpose portable AC for medium-large rooms and don't mind a bit of background noise or moderate energy use.

The BLACK+DECKER Smart Portable Air Conditioner offers a solid option for cooling rooms up to about 500 square feet with its 12,000 BTU capacity. While the seasonal energy efficiency ratio (SEER) of 5.8 is moderate and it is not Energy Star certified, it provides decent cooling power for the price. Noise level sits around 52 dB, which is fairly average—noticeable but not overly disruptive for most settings like bedrooms or home offices. Its size is typical for portable units, and though it weighs nearly 57 pounds, it remains movable with some effort. The included window installation kit simplifies setup, though proper ventilation remains necessary for optimal performance.

A standout feature is the smart functionality; it supports Wi-Fi control through a mobile app and voice commands via Alexa or Google Assistant, adding convenience uncommon in many portable ACs. The Follow Me remote is also a nice touch, using its location to adjust cooling precisely where you are. It doubles as a dehumidifier and fan, offering versatility through the warmer months. On the downside, the water tank capacity is small (0.8 liters), which could require frequent attention in very humid environments unless auto-evaporation works effectively.

Due to the lack of Energy Star rating, it might consume more electricity than more efficient models, so it's best suited for users who value smart features and ease of use over maximum energy savings. This unit is a good fit for homeowners or renters who want a reasonably powerful, easy-to-control portable AC with smart technology, though it might not be the best pick if low noise or top-tier efficiency is a priority.
