10 Best Mini Splits 2025 in the United States

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.

The Senville LETO Series Mini Split Air Conditioner Heat Pump is a compact and efficient option for cooling and heating smaller spaces. With 9000 BTU, it’s suitable for rooms up to 400 square feet, making it a good fit for bedrooms, living areas, and even small commercial spaces. Its SEER of 21.5 indicates excellent energy efficiency, potentially lowering your energy bills. Additionally, the system includes a heat pump that works even in temperatures as low as 5°F, making it versatile for year-round use.

The noise level of 25 dB ensures quiet operation, which is ideal for maintaining a peaceful environment. The unit supports one zone, so it’s best suited for single-room applications rather than whole-house solutions. A notable special feature is its compatibility with Alexa, allowing for convenient voice control and integration into smart home systems. However, it's important to note that the system requires professional installation, which could add to the initial cost. The installation kit is comprehensive, including a 16ft line set and communication wire, but labor costs are not covered under the warranty.

With a 5-year warranty on parts and the compressor, Senville provides good long-term support. The device is not Energy Star compliant, which might be a consideration for those prioritizing energy standards. Lastly, the stylish design ensures it won’t be an eyesore in any setting.

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.
