10 Best 8000 Btu Air Conditioners 2025 in the United States

The BLACK+DECKER 8,000 BTU Portable Air Conditioner is a solid choice for cooling rooms up to about 350 square feet. It’s a portable unit, which means you can easily move it between rooms thanks to built-in casters and side handles. This flexibility is great if you don’t want a permanent installation or if you want to cool different areas at different times. The unit offers a 3-in-1 function, working not just as an air conditioner but also as a fan and dehumidifier, which is useful in humid climates or during muggy summer days. Controlling the temperature is straightforward, with a remote control and a top-mounted LED display for easy adjustments. It also includes a slide-out washable filter, which helps keep the air clean and is simple to maintain.

On the downside, the energy efficiency (SEER of 5.4) is moderate and it’s not Energy Star certified, so it might use more electricity compared to more efficient models. The noise level is about 54 decibels, which is noticeable but not overly loud—comparable to a normal conversation—so it’s generally okay for bedrooms or living rooms but might be a bit distracting for very quiet spaces. Installation is fairly easy with the included window kit and exhaust hose, though you do need a window nearby for venting hot air outside. The water tank capacity is quite small (0.45 liters), but it uses auto water evaporation to reduce emptying frequency.

This portable AC unit provides a convenient, all-in-one cooling solution for medium-sized rooms. It suits those who want a flexible, easy-to-use unit without complex installation. However, if energy savings or very quiet operation are your top priorities, you might consider other models.

The BLACK+DECKER Portable Air Conditioner with an effective cooling capacity of 8,000 BTU (SACC) is suitable for medium-sized rooms up to around 500–550 sq. ft., making it a good fit for bedrooms or small living areas. It is a three-in-one device working as an air conditioner, dehumidifier, and fan, which adds versatility. The unit includes a handy Follow Me remote control that acts like a thermostat, allowing for more precise temperature management wherever you are in the room. Moving the unit around is simple thanks to built-in casters and side handles, and installation is straightforward with the included window kit.

Noise level is moderate at 52 dB, which is comparable to a quiet conversation—generally acceptable for bedrooms but might be noticeable in very quiet environments. The energy efficiency ratio (SEER) of 5.8 is on the lower side, and this model is not Energy Star certified, so it may use more electricity than more efficient units. It uses an environmentally friendly R410a refrigerant, which is a plus. The unit also features auto water evaporation, reducing the need for manual water draining in many cases. Weighing nearly 57 pounds, it is portable but still somewhat heavy, so mobility depends on using the casters properly. The one-year warranty is standard but relatively short.

This BLACK+DECKER air conditioner is a practical choice if you want a portable, multifunctional unit with easy installation and good cooling for medium rooms, but energy efficiency and noise could be improved.

The LG 8,000 BTU Window Air Conditioner is well-suited for cooling medium-sized rooms up to 350 square feet, making it ideal for bedrooms, living rooms, or apartments. It has a relatively high Seasonal Energy Efficiency Ratio (SEER) of 13, which means it's fairly efficient in its energy use, although it does not have an Energy Star rating. One of its standout features is the quiet operation, with noise levels as low as 53 dB in low mode, making it a good choice for light sleepers or those who prefer a quieter environment.

The unit offers multiple fan speeds and an Auto Cool function, providing customizable comfort based on user preferences. The digital control panel and included remote control add to its ease of use, along with a 4-way air deflection system for flexible cooling direction. Installation is facilitated by an included window installation kit, and the slide-out, washable filter makes maintenance simple. An Auto Restart function ensures that the unit resumes its operation after power failures, which can be very convenient.

However, it's worth noting that installation may require some effort due to its weight of 58 pounds. Despite its good performance, the lack of an Energy Star rating means it may not be the most energy-efficient option available. Those looking for a quiet, reliable, and relatively easy-to-use window air conditioner for a medium-sized room may find this LG model to be a suitable choice.
