The BLACK+DECKER 10,000 BTU Portable Air Conditioner is suitable for cooling rooms up to 450 square feet, making it an excellent choice for bedrooms or small living areas. One of its major strengths is its portability, thanks to its casters and side handles, which allow for easy movement between rooms. Additionally, it has a 3-in-1 functionality, serving as an air conditioner, dehumidifier, and fan, providing versatility for different weather conditions.

The unit comes with a remote control and a top-mounted control panel with LED display, making it user-friendly. The slide-out washable filter is a convenient feature for maintenance, and the auto water evaporation system reduces the need for manual water removal. The 24-hour programmable timer adds flexibility in managing cooling schedules.

On the downside, its Energy Efficiency Ratio (EER) is 6.7, which is relatively low, indicating it may not be the most efficient option in terms of energy consumption. Additionally, the noise level is 52 dB, which might be noticeable, especially during sleep. Despite these drawbacks, the included installation kit simplifies the setup process, and the unit's cooling power is sufficient for the specified room size. This air conditioner is ideal for users looking for convenience, portability, and multi-functionality in a single device.

The GE Profile PHNT10CC ClearView Window Air Conditioner is a well-rounded unit suitable for medium-sized rooms up to 450 square feet. With its 10,300 BTU capacity and inverter technology, it provides efficient cooling while being 34% more energy-efficient, which is great for saving on electricity bills. Its ultra-quiet operation, at only 40 dB, makes it ideal for noise-sensitive environments, like bedrooms or home offices.

Installation is straightforward due to the unique flex-depth design, accommodating a range of wall thicknesses. This model also allows you to maintain your window's full view, which is a rare feature in window AC units. It fits windows 20" to 40" wide and requires a minimum window opening height of 13".

The built-in Wi-Fi and compatibility with smart devices such as Amazon Alexa and Google Assistant are standout features, offering convenience and control via the SmartHQ app or remote control. This adds an extra layer of ease in operation, especially if you enjoy managing home appliances remotely. A notable downside could be its size and weight, at 75.7 pounds, which might require assistance during installation. Additionally, while it boasts a SEER of 11.2, it’s moderately efficient compared to some of the highest-efficiency models in the market. However, the Energy Star certification does promise reasonable energy savings.

The air filter and filter light reminder provide convenient maintenance, ensuring the unit runs effectively. This air conditioner is a strong contender for those seeking quiet operation, energy efficiency, and smart features in a medium-sized room.

Its standout feature is the unique U-shaped design which lets you keep your window partly open for fresh air without sacrificing security or noise control. Speaking of noise, this unit operates very quietly at just 32 decibels, making it one of the quietest air conditioners in this category. Thanks to its inverter technology, it uses about 35% less energy than traditional window ACs, earning an ENERGY STAR certification which means lower electricity bills. It has a decent Energy Efficiency Ratio (EER) of around 11.2 (calculated from 10,000 BTU cooling and 890 watts power), so it's quite efficient at cooling compared to power used.

The unit offers some smart features including Wi-Fi control through an app and compatibility with Alexa and Google Assistant, allowing easy remote operation and programmable timers. Installation is user-friendly with a quick-snap bracket designed for standard single or double-hung windows between 22 and 36 inches wide.

Also, it relies on a power cord and standard 115V electricity, typical but worth noting.

This Midea U Shaped Smart Inverter AC is a great option for users seeking a quiet, energy-efficient, and smart-controlled window air conditioner for medium rooms, especially if you want flexibility with window opening and modern smart home integration.
