10 Best Mini Splits 2025 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 YITAHOME 12000 BTU Mini Split is a solid choice if you need to cool or heat a medium-sized room up to 750 sq. ft., such as a bedroom, living room, or small office. It offers efficient performance with a high SEER rating of 20, meaning it uses less energy than many other models to keep your space comfortable. The inverter compressor helps save energy and maintain consistent temperatures. It also has a good heating function, working well even in cold weather down to 5°F.

One of its stronger points is the quiet operation, with noise levels under 41 decibels—this means it won’t be disruptive while running, which is great for sleeping or working. Plus, it comes with WiFi and Alexa compatibility, allowing remote control through your phone or voice commands for added convenience. The system supports five different modes, including auto, dry, and energy-saving, and includes helpful features like air purification and automatic cleaning.

Installation requires professional help, as the unit comes with most parts but excludes shut-off valves and some protective elements, which might add to the setup cost and complexity. It is designed as a single-zone system, meaning it cools or heats one area rather than multiple rooms separately. If you have a larger space or want multi-zone control, this model may not fully meet those needs. For those looking for an energy-efficient, quiet mini-split with smart features to manage a single room, the YITAHOME 12000 BTU represents a practical, modern option backed by a 5-year warranty.

The DELLA Versa Series 24000 BTU Mini Split AC is a robust choice for those needing a powerful cooling and heating solution for spaces up to 1500 sq. ft. It boasts an impressive 19 SEER2 rating, indicating high energy efficiency, and features a 2-ton heat pump that works efficiently even in cold environments down to 5°F. Its inverter system and DC Inverter technology help save up to 30% on power, making it a cost-effective option in the long run. Additionally, the unit is compatible with Alexa and WiFi, allowing for convenient remote control operation. The inclusion of smart functions like 4D air flow, multiple fan speeds, and various modes (heating, cooling, dehumidifying) adds to its versatility and user comfort.

This mini-split system requires professional installation due to the need for line-set vacuuming and potential adjustments to freon levels if the line-set length is altered. It is not suitable for DIY installation, which might be a drawback for some users. With a noise level of only 35 dB, it operates quietly, making it ideal for use in bedrooms or living spaces without disturbance. The comprehensive installation kit provided simplifies the setup process for professionals.

The DELLA Versa Series is a reliable and efficient mini-split AC for larger spaces, combining advanced technology with user-friendly features, though it requires professional installation.
