Hisense 8,000 BTU Portable Air Conditioner with Dual Hose & Inverter, 350 Sq Ft, Wi-Fi, ConnectLife App Google and Alexa, 3 operating modes, Noise 42 dB(A) - HAP0824TWD (Renewed), White
Most important from
270 reviews
The Hisense 8,000 BTU portable air conditioner is a solid choice if you need efficient cooling for a room up to about 350 square feet. Thanks to its dual-hose design, it cools faster and more efficiently than many single-hose units by avoiding the vacuum effect that slows cooling. Its inverter technology also helps save energy, making it about 40% more efficient than standard portable ACs, which is great if you want to keep electricity costs down. Noise-wise, it runs quietly at 42 decibels on its quiet mode—roughly the sound of a gentle conversation—so it won’t disturb your sleep or work.
The unit offers three operating modes (cool, dehumidify, and fan) and multiple fan speeds, letting you adjust airflow to your comfort. Setup is relatively straightforward with an easy snap-together window kit that fits various window sizes. In addition, smart features like Wi-Fi connectivity and compatibility with Google and Alexa allow convenient remote control via the ConnectLife app or voice commands.
On the downside, the unit weighs 61 pounds, making it a bit heavy for frequent moves, and it requires a window for venting, which may limit placement options. Also, while the 90-day warranty is standard for renewed products, it’s shorter than for new units, so keep that in mind. This Hisense model is a portable, energy-saving air conditioner with smart home features and quiet operation suited for medium-sized rooms.

Midea 12,000 BTU U Shaped Smart Inverter Window Air Conditioner - Cools 550 Sq Ft, Ultra Quiet with Open Window Operation - Alexa/Google Assistant Compatible, 37% Energy Savings, Remote (2026 Edition)
Most important from
105 reviews
The Midea 12,000 BTU U Shaped Smart Inverter Window Air Conditioner is designed to cool rooms up to 550 square feet efficiently. Its U-shaped design is unique, allowing your window to stay partially open for fresh air and a better view, which is a notable advantage over traditional window units. The inverter technology helps reduce energy consumption by over 37%, making it one of the more energy-efficient options with an ENERGY STAR certification. You can expect a seasonal energy efficiency ratio (SEER) of 15.0, which means it manages electricity use well during cooling. Noise is a strong point here—the unit operates as quietly as 32 decibels, which is quieter than many other window air conditioners, thanks in part to its design blocking outside noise. This makes it suitable for bedrooms or living rooms where low noise is appreciated. The AC offers smart features like Wi-Fi connectivity, allowing control through an app or voice commands via Alexa and Google Assistant. This adds convenience, especially if you want to adjust settings without going to the unit.
Installation is relatively straightforward with included brackets, but it requires a window 23 to 36 inches wide and at least 19.5 inches high, which might limit compatibility with some windows. Weighing nearly 57 pounds, it’s a bit heavy, so assistance might be needed during setup. The unit uses the R-32 refrigerant, which is more environmentally friendly than older types. Although the product saves energy compared to traditional models, its annual consumption is still around 6220 kWh, which might be significant depending on your local electricity rates. Also, while cooling capacity is solid for medium-sized rooms, larger spaces would need a more powerful unit. This air conditioner is well suited for users looking for quiet, energy-efficient cooling with smart controls and the flexibility of an open window, making it ideal for bedrooms and living rooms within its size range.

The Hisense 8,000 BTU portable air conditioner is designed for cooling small to medium rooms up to about 350 square feet, making it a good choice for bedrooms or living spaces. Its inverter technology helps reduce electricity use by up to 40%, making it energy efficient and potentially saving money on your power bill. The dual-hose setup cools faster and keeps temperatures steady compared to single-hose models. Noise-wise, it runs quietly at around 42 decibels, so it won’t disturb your sleep or work.
The unit offers 3-in-1 functions: cooling, dehumidifying, and fan-only mode, adding versatility for different weather or comfort needs. You can control it easily with a remote, the touchscreen, or via smartphone apps and voice assistants like Google and Alexa, which is handy for modern smart homes. The size and weight (65 pounds) mean it’s portable but might require some effort to move around.
This Hisense unit suits someone looking for an energy-saving, quiet portable AC with smart features for a room around 350 sq ft. It is less ideal if you need a larger cooling capacity or longer warranty coverage, as it comes with only a 90-day limited warranty.
