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 TOSOT 24,000 BTU Dual 2 Zone Mini Split is a solid choice for those looking to cool and heat two separate rooms efficiently. With two 12,000 BTU indoor units controlled by one outdoor unit, it offers customizable temperatures, which is great if different zones need varying comfort levels. Its 21 SEER2 rating means it’s quite energy efficient, saving you money compared to older or less efficient systems. The unit is Energy Star-certified and even qualifies for federal tax rebates, adding to the cost benefits.

Installation is easier than traditional central AC since it’s ductless, reducing complexity and potential expenses. The included 16.4-foot copper line set helps, though you’ll need to get a power cord separately. Its noise level of 58 decibels is moderate; it won’t be completely silent but should be quiet enough for most living spaces. Heating is reliable too, with an advanced compressor and intelligent defrost function allowing it to work well in a wide range of temperatures—from cold winters to hot summers. This makes the unit suitable for many climates.

Smart features include WiFi control through the Gree+ app and support for Google Assistant voice commands, which can make operation simple and convenient. The setup requires careful coordination since parts may arrive separately, and you should plan installation only after receiving everything. Also, the unit is somewhat heavy at 220 pounds and requires a 230-volt power supply, which might need professional handling. This TOSOT mini-split system fits well for homeowners wanting efficient, multi-zone heating and cooling with smart controls, especially if they want to avoid ductwork. It balances good energy savings, weather resilience, and user-friendly features, though installation planning and power requirements might need extra attention.

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.
