10 Best Mini Splits 2026 in the United States

The Senville LETO Series Mini Split is a solid choice if you're looking to cool or heat a space around 1,250 square feet. It delivers 24,500 BTU, which means it has strong cooling and heating power suitable for medium to larger rooms or multiple connected areas (zones). It comes with a good energy efficiency rating (SEER 17), helping reduce electricity bills compared to less efficient units. The noise level is quite low at 34 decibels, so it won't disturb your daily activities or sleep.

This model is versatile, offering cooling, heating down to 5°F (which covers most mild winters), a dehumidifier, fan, and a turbo mode for quick temperature changes. A standout feature is its Alexa compatibility, allowing you to control it through voice commands or a smartphone app for convenience. Installation requires a professional since it comes with a complete kit but no DIY setup instructions, and the unit includes a 16-foot copper line set pre-loaded with refrigerant.

The warranty covers parts and compressor for 5 years, providing peace of mind, though labor costs aren't included. One drawback is that it’s not rated under the BEE Star program, which might matter in some regions focused on strict energy standards. While it supports two tons of capacity, it’s designed generally for single-zone setups unless you install multiple units. This mini-split is a stylish and efficient option for homes or small businesses seeking quiet, reliable climate control with smart features.

The DELL Versa Series 12000 BTU Mini Split Air Conditioner stands out in the mini-split category with impressive energy efficiency and a range of smart features.

The unit's heat pump function is effective even in freezing temperatures, making it a versatile choice for various climates. Its noise level is quite low, operating at 30-41 dBa, which is an excellent feature for bedrooms or quiet living areas.

There are some drawbacks to consider. Installation is not a DIY project; it requires professional help due to the need for proper line-set vacuuming and adjustments to freon levels, which can add to the total cost. While the included 16.4 ft installation kit is helpful, potential homeowners should factor in the additional installation expenses. Additionally, while the smart sensor feature enhances comfort by sensing temperature from the remote control, it may not appeal to those who prefer manual control over their air conditioning settings.

If you're looking for a smart, efficient mini-split system and don't mind the installation requirement, this unit could be a great addition to your home.

The unit operates quietly at 43 dB, so it won't be disruptive in a home or office setting.

It includes smart WiFi connectivity compatible with Google Assistant and Amazon Alexa, giving you remote control via phone or voice commands for added convenience. The system supports only a single zone, meaning it’s best for one main living or working area rather than multiple rooms. The unit has a modest 2-star energy rating, offering reasonable energy efficiency.

This mini-split is well suited for buyers looking for a straightforward, easy-to-install system with smart features and reliable all-season comfort without needing complex multi-zone setups.
