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 MRCOOL Easy Pro 12,000 BTU ductless mini-split is a solid choice if you need to heat or cool a medium-sized room (up to about 550 square feet). Its 12,000 BTU capacity is well-suited for such spaces, providing reliable comfort year-round with both heating and cooling functions. One of the biggest plus points is its DIY-friendly installation, which can save you a lot on professional setup costs and hassle. It runs quietly at about 43 decibels, so it won’t disturb your daily activities or sleep.

Energy efficiency is decent, but the product has a 2-star BEE rating, so it may not be the most cost-effective in energy use compared to higher-rated models. It’s designed for a single-zone setup, making it best for one room or area rather than multiple zones. The inclusion of smart WiFi control is very convenient, allowing you to adjust temperature from anywhere using your phone or voice assistants like Alexa and Google Assistant.

The compact white unit blends well with most interiors and offers fast cooling capabilities. If you have a larger home or need multi-zone control, this model might fall short. Also, while DIY installation is a big advantage, it requires some comfort with basic setup tasks. This makes it a good option for budget-conscious buyers who want a straightforward, quiet, and smart mini-split system for a single room.
