10 Best Energy Efficient Portable Air Conditioning Units 2025 in the United States

The BLACK+DECKER Smart Portable Air Conditioner with Heat offers significant versatility with its four-in-one functionality, providing cooling, heating, dehumidification, and fan options. Its cooling capacity reaches 14,000 BTU ASHRAE (10,000 BTU DOE), making it suitable for rooms up to 700 sq. ft., while the heating function delivers 12,000 BTU, ensuring year-round usability.

Despite its high cooling power, it operates at a relatively moderate noise level of 54 dB, which is comfortable for most users, especially during sleep. However, its SEER of 6.2 indicates that it is not the most energy-efficient option available, which may be a concern for those prioritizing energy savings. The unit includes a 'Follow Me' remote control feature, enhancing user convenience by allowing precise temperature control. Additionally, it supports smart technology with voice control via Amazon Alexa or Google Assistant and can be managed through a dedicated mobile app.

Portability is well-addressed with its compact form factor and included installation kit, making setup straightforward. The absence of an Energy Star rating reflects its lower energy efficiency, potentially leading to higher energy costs compared to more efficient models. For filter maintenance, regular cleaning is necessary to ensure optimal performance. This unit is ideal for users seeking a versatile, smart-controlled portable air conditioner that can also provide heating, although energy-conscious buyers might want to consider options with higher energy efficiency ratings.

The BLACK+DECKER Smart Portable Air Conditioner offers strong cooling with 14,000 BTU, making it suitable for medium to larger rooms up to 700 square feet. It effectively combines air conditioning, dehumidifying, and fan functions, which is useful if you want more than just cooling. The energy efficiency rating (SEER of 6.2) is decent for this class but not the highest, so it should save some power without being the most economical option. Noise-wise, at 54 dB, it’s about as loud as a normal conversation, which is typical for portable AC units but might be noticeable in very quiet rooms.

Portability is decent, with a manageable size and included installation kit, allowing you to easily move and set it up in different spaces. The washable filter helps keep maintenance simple and affordable. One of its standout features is the smart connectivity, allowing control via an app or voice commands through Alexa or Google Assistant, plus the handy "Follow Me" remote that measures temperature where you are for more precise cooling. It also includes a programmable timer and thermostat for better control of cooling schedules.

The unit is somewhat heavy (over 60 pounds) which may affect how easily you can move it frequently. Also, while the energy efficiency is acceptable, users looking for the absolute best energy savings might want to explore higher EER models. This BLACK+DECKER model is a solid choice if you want reliable cooling with modern smart features and decent portability for medium-sized rooms, though it may not be the quietest or most energy-efficient option available.

The BLACK+DECKER Portable Air Conditioner (model BPACT08WT) offers a cooling capacity of 9,000 BTU (ASHRAE) and 5,300 BTU (DOE), which is suitable for rooms up to 400 sq. ft. This makes it a good option for bedrooms or small living spaces. One of its strengths is the 'Follow Me' remote control feature, allowing precise temperature control based on the remote's location. This unit also functions as a dehumidifier and fan, adding versatility to its cooling capabilities.

It has a relatively low EER (Energy Efficiency Ratio) of 5.4, which may not be the most energy-efficient option available. The noise level of 54 dB is moderate, meaning it won't be completely silent but should not be overly disruptive either. Portability is a key feature, with casters and side handles making it easy to move between rooms. The included installation kit simplifies the setup process.

Maintenance is straightforward with the washable filter, although it may require regular cleaning to maintain performance. The BLACK+DECKER Portable Air Conditioner is a versatile and user-friendly option for cooling small to medium-sized rooms, with the main drawbacks being its lower energy efficiency and moderate noise level.
