10 Best Smart Air Conditioners 2026 in the United States

The Senville LETO Series Mini Split Air Conditioner Heat Pump is a versatile option with a cooling capacity of 12,000 BTU, which is suitable for medium-sized rooms. Its SEER2 rating of 20.8 indicates high energy efficiency, helping to reduce electricity costs. The integration with Alexa is a standout feature, allowing voice control and remote adjustments, adding to the convenience and smart home integration appeal.

The unit works as a 4-in-1 system, providing air conditioning, heating (functional down to 5°F), dehumidifying, and fan options, making it useful year-round. Additionally, it includes a DC Inverter for quieter and more efficient operation and is stylishly designed for both home and commercial use. However, it is not Energy Star compliant, which might be a concern for those looking for products with this certification. Installation requires a professional, which can add to the initial cost.

Despite these points, the included installation package and a 5-year warranty on parts and the compressor offer peace of mind. This unit is ideal for users seeking a smart, energy-efficient, and multi-functional air conditioning solution with robust support and warranty options.

The LG 24,500 BTU Smart Window Air Conditioner is designed to cool large spaces, up to about 1,560 square feet, making it a suitable choice for big bedrooms, living rooms, or small apartments. Its cooling power is strong enough to provide comfortable temperatures in sizable areas. The unit features LG’s ThinQ smart technology, allowing you to control it remotely via smartphone or voice assistants like Alexa and Google Assistant, which adds convenience if you want to adjust settings without getting up.

It offers three fan speeds and a 24-hour timer, so you can customize airflow and set schedules to save energy. The noise level can be as low as 50 decibels on the quiet setting, which is relatively mild and should not be disruptive in most home environments. It also includes a filter reminder light to help maintain clean air. Installation is straightforward with the included window kit, but being a window unit, it requires a suitable window and some effort to set up.

The energy efficiency rating (SEER 10.3) provides decent performance, though it may not offer the highest level of energy savings. The 1-year warranty is standard for this type of product. This LG model stands out for its strong cooling capacity and smart features, making it well suited for users needing to cool larger rooms while enjoying convenient remote control options.

The Dreo Portable Air Conditioner offers a solid cooling capacity of 10,000 BTU, which is good for cooling rooms up to around 200 square feet, making it a suitable choice for bedrooms or small living spaces. It uses a patented IceCool system that quickly cools the area and allows temperature control between 61°F and 86°F, so you can find a comfortable setting easily. Energy efficiency is decent with a SEER rating of 6.51, balancing power use and performance fairly well for a portable unit.

One of its standout features is the smart climate control, letting you manage the AC with voice commands through Alexa, Google Home, or Siri, and the app that monitors temperature and humidity. This gives you convenient control whether you're in the room or away. The noise level is also quite low at 45 dB, which is quiet enough not to disturb sleep or concentration. The unit includes a drainage-free system that automatically handles excess water, a big plus if you dislike the hassle of manual draining. Installation is user-friendly with modular window panels and caster wheels for easy movement between rooms.

Being a portable model, it’s heavier than some (over 57 pounds), so while it has wheels, moving it around might require a bit of effort. It’s designed well for typical bedroom use, especially if you want smart features and quiet operation without permanent installation. For smart, convenient cooling in smaller rooms, this Dreo unit performs effectively, though other models might be better suited for larger spaces or specific advanced air filtration and energy-saving needs.
