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 Daikin 24,000 LV Series mini split is a solid choice for those needing efficient heating and cooling in medium to large rooms, covering up to about 1,460 square feet. It delivers strong cooling at 21,400 BTUs and heating at 25,400 BTUs, making it suitable for year-round use even in colder climates down to 5°F. Its high 19.5 SEER2 rating means it uses energy efficiently, potentially lowering electricity bills compared to older or less efficient units. The noise level is relatively quiet at 37 decibels, so it won’t be disruptive in living spaces.

This system is a single-zone split type, meaning it controls one area, which works well for a single room or open space but may not be ideal if you want to manage temperatures in multiple separate rooms. Installation requires professional setup due to its split system design, which might add to upfront costs but ensures proper function and reliability. The unit comes with useful smart features like an Intelligent Eye sensor that adjusts airflow based on room occupancy, an energy-saving Econo Mode, and self-diagnostics to catch issues early. It also includes accessories like a 15-foot installation kit and a wall bracket, making installation a bit easier.

Although it does not have an Energy Star rating, which some buyers look for to guarantee top-tier energy efficiency, this Daikin mini split delivers dependable performance and smart features for those needing an efficient heating and cooling solution for one main area, especially in climates with varying temperatures. While the noise is low, some may prefer even quieter units for bedrooms or very quiet spaces.

The MRCOOL 24000 BTU Easy Pro Series mini split is a solid choice for heating and cooling spaces up to about 1,050 sq ft, making it suitable for medium-sized rooms in homes, offices, or small commercial areas. It offers both cooling and heating functions, so you can rely on it throughout the year. The 24,000 BTU capacity is strong enough for effective temperature control without overworking the system. It’s designed as a ductless unit, which means installation is simpler and less invasive compared to traditional HVAC systems, and it’s promoted as DIY-friendly, which could save installation costs if you're comfortable with basic setup. The noise level at 43 dB is moderate—quiet enough for most indoor spaces but not completely silent, so it might be noticeable in very quiet rooms.

The unit includes useful smart features like a timer and refrigerant leak detection, as well as Active Clean Technology to maintain good indoor air quality by keeping the filters easy to clean and fresh. On the downside, its energy efficiency rating (BEE 2 Star) is not the highest available, so it might use more electricity compared to more efficient models, which could affect long-term running costs. Additionally, it supports only a single zone, so it’s best if you want to control one area rather than multiple rooms separately.

This mini split provides a practical option for those seeking a straightforward, year-round climate solution with some smart safety and air quality features. However, if ultra-quiet operation or top energy savings are a priority, other models may better suit those needs.
