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 Easy Pro 24k BTU mini-split is a solid choice for cooling and heating medium-sized spaces between 500 and 1200 square feet, like game rooms or garages. With a cooling capacity of 24,000 BTU and a high SEER rating around 19.8 to 20.2, it offers efficient performance that can help reduce energy bills. Its heating capability is also strong, supported by an HSPF rating of 11.2, making it suitable for year-round comfort. The system operates quietly at about 43 decibels, which is fairly low and won't be disruptive indoors. Installation is user-friendly for those comfortable with DIY projects, especially since it comes with a 16-foot line set and wall-mount setup, though professional help might still be needed for some. Only one zone is supported here, so it’s best if you’re looking to condition a single room or area rather than multiple zones. Durability is enhanced by a Gold Fin condenser coating that helps prevent rust and corrosion. A 1-year labor warranty provides some peace of mind, though longer coverage would be ideal.

This MrCool mini-split is well suited for homeowners wanting an energy-efficient, relatively quiet, and straightforward heating and cooling solution for a single room, especially if they want to handle installation themselves. If you need multi-zone control or extended warranty support, other options might better meet your needs.

The Senville SENA-30HF/T Tri Zone Mini Split is a strong choice for those seeking an efficient and versatile air conditioning and heating solution. With a cooling power of 28,000 BTU, it's suitable for large areas up to 1500 square feet and can handle multiple rooms due to its tri-zone capability. Its high SEER rating of 23.0 indicates excellent energy efficiency, which can lead to significant savings on electricity bills.

Additionally, the unit operates quietly at 25 dB, making it suitable for bedrooms and other quiet spaces. The Alexa-enabled feature adds convenience, allowing for voice or app control, enhancing ease of use and energy savings. The installation kit is comprehensive, though professional installation is required, which might be an added cost to consider.

It's backed by a solid warranty—10 years on the compressor and 5 years on parts—which provides peace of mind. If you need a reliable, efficient mini-split system for multiple rooms, the Senville SENA-30HF/T is worth considering, especially for home or small business use.
