10 Best Window Ac Unit For Sliding Window 2026 in the United States

The Midea MAW08V1QWT is an 8,000 BTU window air conditioner designed for single or double-hung windows between 22 to 36 inches wide and at least 13.75 inches high, making it suitable for many sliding windows. Its standout feature is the unique U-shaped design that allows the window to stay partially open, so you can enjoy fresh air and maintain your view. This model runs very quietly at just 32 decibels, thanks to its inverter technology, making it one of the quietest window AC units available.

It’s also energy efficient, with a SEER rating of 15 and ENERGY STAR certification, which means it uses about 35% less power than traditional models—good news for your electricity bill. The unit supports smart controls through Wi-Fi, letting you operate it remotely via an app or voice assistants like Alexa and Google Assistant, adding convenience. Installation is straightforward with a quick-snap bracket included, but the unit is somewhat heavy at 55.6 pounds, so you might want some help during setup.

While it cools rooms up to around 350 square feet effectively, it may struggle in larger spaces. The noise level and energy savings are impressive, but the price and weight could be a consideration for some buyers. This Midea AC is a solid choice if you want a quiet, energy-efficient window unit that doesn’t block your window view and offers smart features, especially suited for small to medium rooms with sliding windows.

The Midea Duo 14,000 BTU Portable Air Conditioner offers impressive cooling capacity, making it suitable for rooms up to 550 sq. ft. The innovative hose-in-hose design enhances air circulation and prevents hot air from entering, which is a significant advantage for maintaining cool temperatures indoors. Additionally, the unit boasts an inverter technology that ensures high energy efficiency, saving up to 40% more energy compared to standard portable units, making it a cost-effective option for long-term use.

The air conditioner operates ultra-quietly at 42 dB, which is quieter than typical models and comparable to the noise level of a library, ideal for maintaining a peaceful environment. It features smart Wi-Fi integration, allowing control through the Midea Air app or voice assistants like Alexa and Google Assistant, offering modern convenience.

However, despite these strengths, the unit is primarily a portable air conditioner and may require modifications for installation in sliding windows. The window kit included might not provide a perfect fit for all sliding window types, potentially necessitating additional adjustments. Additionally, while the unit's cooling power and efficiency are excellent, it operates at a higher noise level of 52.6 dB under some conditions, which might be noticeable in quieter settings. Lastly, the unit's size and weight mean it may require sufficient space for setup and might not be the most compact option for smaller rooms. Those looking for a versatile, energy-efficient cooling solution for larger spaces and modern connectivity will find this product appealing, though installation compatibility with sliding windows should be verified prior to purchase.

The LG 8,000 BTU Window Air Conditioner is designed to cool medium-sized rooms up to 350 square feet, making it a good fit for bedrooms, living rooms, or apartments. It operates at a relatively quiet 53dB in low mode, which is beneficial for maintaining a peaceful environment for sleeping or working. With its 3 cooling and fan speeds, along with an Auto Cool feature, it provides flexibility in temperature control tailored to your comfort needs.

The unit includes a digital control panel and a remote control for ease of use, and its 4-way air deflection ensures effective cooling distribution throughout the room. The auto-restart function is a handy feature, automatically turning the unit back on after a power outage. Additionally, the air conditioner comes with a filter light reminder, a washable filter, and an installation kit, making maintenance and setup straightforward.

The unit's Seasonal Energy Efficiency Ratio (SEER) of 13 and the absence of an Energy Star rating indicate it may not be the most energy-efficient option available. Its compatibility with sliding windows is not explicitly mentioned, so potential buyers with such windows should verify this aspect before purchasing. At 58 pounds, it is relatively heavy, which might complicate installation for some users. Despite these drawbacks, the air conditioner offers reliable performance and useful features for cooling medium-sized rooms.
