10 Best Wifi Air Conditioner 2025 in the United States

The Midea 12,000 BTU Smart Inverter Window Air Conditioner is a solid choice if you need reliable cooling (and heating) for a medium to large room, up to 550 square feet. Its inverter technology boosts energy efficiency, which helps lower electricity bills by about 35% compared to standard models. With a Seasonal Energy Efficiency Ratio (SEER) of 13.3 and Energy Star certification, it ranks well for saving energy. The unit is WiFi-enabled and compatible with Alexa and Google Assistant, making it easy to control remotely or by voice, which is handy if you like smart home features.

You get 5 operating modes including heat, cool, dry, fan, and auto, plus a convenient 24-hour timer and multiple fan speeds. Noise-wise, it runs quietly enough (around 45-58 dB) to not disturb conversations or sleep, although the spec sheet mentions 58 dB which is on the louder side compared to some ultra-quiet models. Installation fits most double-hung windows between 24 and 38.5 inches wide, and the included kit makes setup fairly straightforward. The washable front filter is easy to maintain, helping keep air quality decent.

One limitation is the heat function will not operate if outdoor temperatures drop below 41°F, so it’s better suited for mild climates or seasonal heating. Some users may find the 58 dB noise level a bit noticeable in very quiet rooms. This unit balances cooling power, energy savings, and smart features well, making it a practical choice for those wanting a versatile and remotely controllable window air conditioner with heating and dehumidifying capabilities.

The BLACK+DECKER Smart Portable Air Conditioner offers a solid cooling solution for rooms up to 550 sq. ft. with its 12,000 BTU capacity, which is suitable for medium-sized bedrooms or living spaces. It stands out with Wi-Fi connectivity and supports voice control via Amazon Alexa and Google Assistant, making it convenient for smart home users. The included “Follow Me” remote has a thermostat function that helps maintain precise temperature control based on your location, enhancing comfort.

In terms of energy efficiency, this unit has a Seasonal Energy Efficiency Ratio (SEER) of 5.8, which is moderate but not Energy Star rated, so it may consume more power compared to some other models. Noise level is about 52 dB, which is noticeable but generally acceptable for a portable AC, though it might be slightly loud for very quiet environments like bedrooms at night. Installation is straightforward with the included window kit, making setup manageable without professional help. The unit also features auto water evaporation, so you won’t have to worry much about emptying water frequently. The filter type isn’t specifically detailed, which is something to keep in mind if you are sensitive to air quality or need advanced filtration.

The portable design means you can move it around easily, but at nearly 57 pounds, it might require some effort to relocate. This product has a decent customer rating (4.1 out of 5), indicating general satisfaction, though its 1-year warranty is fairly standard without extended protection. This BLACK+DECKER model is a solid choice for those wanting smart controls and portability for mid-sized rooms, while being mindful that it may not be the quietest or most energy-efficient option available.

The Senville LETO Series Mini Split Air Conditioner Heat Pump offers a versatile and powerful solution for cooling and heating with a 9000 BTU capacity. The standout feature is its compatibility with Alexa, allowing voice control and app-based management, which is convenient for users who enjoy smart home integration. The unit operates quietly at 25 dB, making it suitable for bedrooms and living areas.

It boasts a high Energy Efficiency Ratio (EER) with a SEER2 rating of 21.5, indicating efficient energy use which can help reduce electricity bills over time. Despite its energy efficiency, it's not Energy Star compliant, which might be a consideration for some users. The system includes a complete installation package but requires professional installation, so it’s not suitable for DIY enthusiasts.

It covers up to 400 square feet, making it ideal for medium-sized rooms. The product comes with a robust warranty—5 years on parts and the compressor—although labor costs are not covered. This mini split system also functions as a dehumidifier and fan, adding value with its multi-functional capabilities. It promises stylish and functional performance for both home and commercial spaces, yet users should be prepared for the initial installation costs. The Senville LETO Series is a reliable choice for those needing a smart, efficient, and quiet air conditioning and heating solution.
