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 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.

The Shinco 8,000 BTU Portable Air Conditioner is a reliable choice for cooling small to medium rooms up to about 200-300 sq.ft. Its 8,000 BTU cooling capacity suits bedrooms or offices, offering adjustable temperatures from 60℉ to 86℉. The energy efficiency ratio (SEER) of 5 provides moderate electricity savings, suitable for typical use. Noise during operation is around 55 dB, noticeable but generally not disruptive, especially with the sleep mode that lowers fan speed and noise for quieter nights.

Portability is a strong point with four casters and a compact design, making the unit easy to move between rooms. Installation is straightforward using the included exhaust hose and window sealing kit, ensuring hassle-free setup. The 3-in-1 function offers cooling, fan, and dehumidifying modes, with a dehumidification capacity of 19.2 liters per day that helps reduce humidity without frequently needing to empty a water bucket. The LED display, remote control, and 24-hour programmable timer add convenience.

Maintenance involves a washable filter, requiring regular cleaning to maintain optimal air quality. The unit weighs 55 pounds, which may be somewhat heavy for some users to carry easily despite the wheels. Cooling coverage varies between 200 and 300 sq.ft, making it best suited for smaller rooms rather than large living spaces. This Shinco air conditioner combines effective cooling, practical features, and easy portability at a reasonable price, making it a solid option for those seeking a compact and versatile cooling solution with simple setup and operation.
