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 MRCOOL 18,000 BTU Easy Pro Series mini-split is designed for heating and cooling spaces up to about 800 square feet, making it suitable for medium-sized rooms or small open-plan areas. It covers both heating and cooling needs, which is great for year-round comfort. Installation is simplified compared to traditional systems, allowing for a DIY approach that can save on professional installation costs. 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.

The Pioneer Diamante Pro 12,000 BTU mini-split is a solid choice for homeowners needing an efficient heating and cooling solution for a single zone. With a cooling capacity of 12,000 BTU (about 1 ton), it suits medium-sized rooms well. Its high SEER rating of 20 means it uses energy efficiently, helping to reduce electricity bills compared to less efficient models. The system also provides heating with a respectable HSPF of 9.5, making it useful year-round in climates that require both heating and cooling.

Installation is relatively straightforward with the included 16-foot line set and accessories, although it requires a 208-230V power supply, so it's best suited for homes with compatible electrical setups. The unit features fast cooling and comes with a wireless remote for easy control, but it doesn't specify smart home connectivity options like Wi-Fi control, which some users might expect in newer models.

This mini-split represents a dependable choice for those seeking a powerful, energy-efficient single-zone system with heating capabilities, though it may lack some of the advanced smart features found in other models.
