10 Best Room Air Conditioners 2025 in the United States

The Midea 12,000 BTU Smart Inverter Air Conditioner efficiently cools rooms up to 550 square feet, featuring inverter technology that helps reduce electricity costs with an Energy Star rating and a SEER of 13.3. It offers heating and dehumidifying functions, making it practical for multiple seasons, though the heating function is not effective below 41°F. The unit operates quietly at about 45 dB, making it suitable for bedrooms or workspaces.

Designed for standard double-hung windows with widths from 24 to 38.5 inches, the installation fits many common window sizes. It includes a washable front filter that is easy to access, which helps maintain air quality and performance. Smart features such as WiFi connectivity allow control via an app or voice assistants like Alexa and Google for added convenience.

The unit weighs 58 pounds, so installation might require assistance. With multiple modes and speeds, this Midea model offers versatile, energy-efficient cooling and supplemental heat, making it appropriate for medium to large rooms and users seeking convenient remote operation without complex setup.

The BLACK+DECKER Smart Portable Air Conditioner with Heat offers a versatile solution for year-round comfort. It boasts a cooling capacity of 14,000 BTU (ASHRAE) and 10,000 BTU (DOE), which is suitable for rooms up to 700 sq. ft. This makes it a solid choice if you need to cool a large space. Additionally, it provides 12,000 BTU heating, making it useful in winter as well. The unit features a 6.2 SEER rating, which is not very high, meaning it is not the most energy-efficient option available.

Its noise level is 54 dB, which is relatively moderate and should not be overly disruptive in most settings. As a portable unit, it offers flexibility in placement, which is convenient if you need to move it between rooms. Installation is simplified with the included window kit and vented airflow outlet. Smart features like Wi-Fi connectivity, mobile app control, and compatibility with Amazon Alexa and Google Assistant add a modern touch to this device, making it easy to control remotely.

The 'Follow Me' remote option, which uses the remote as a thermostat, allows for more precise temperature control. However, it is worth noting that this model is not Energy Star rated, which might be a consideration if energy efficiency is a priority for you. The unit also functions as a dehumidifier and fan, adding to its versatility. It is a well-rounded air conditioner with some notable smart features, though its energy efficiency could be better.

The BLACK+DECKER 8,000 BTU Portable Air Conditioner is a solid choice for cooling smaller rooms up to around 300-350 square feet, making it suitable for bedrooms or small living areas. Its cooling power is effective for personal use, and the unit also offers fan and dehumidifier functions, which adds versatility during different weather conditions. The remote control with a 'Follow Me' feature is a handy addition, allowing the remote to act as a thermostat for more precise cooling, which many users will find convenient. Mobility is another strong point here; with side handles and wheels, it's easy to move the unit between rooms without strain.

Installation is fairly straightforward thanks to the included window kit, though being a portable unit, it requires venting through a window which might not suit all setups. On the downside, the energy efficiency ratio (EER) is on the lower side at 5.4, and the unit is not Energy Star certified, meaning it may use more electricity compared to more efficient models, potentially increasing energy costs. Noise level is moderate at 54 dB, which is typical for portable air conditioners but may be noticeable in quiet environments or during sleep. The product doesn’t specify advanced air filtration features, so it might not be ideal if you need enhanced air cleaning.

The unit has a relatively short 1-year warranty and weighs about 46 pounds, which is manageable but not ultra-light. This BLACK+DECKER model provides a practical, easy-to-use option for those needing portable cooling in small rooms without the need for advanced smart home integration or high energy efficiency.
