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 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 Daikin 24,000 BTU 18 SEER2 Entra R32 Series Mini Split Heat Pump System is a powerful and efficient solution for heating and cooling large spaces up to 1,500 sq. ft. It boasts a high SEER rating of 18, ensuring energy efficiency, and an HSPF rating of 9, making it effective for both cooling and heating. With a noise level of 38 dB, it operates quietly, which is a significant advantage for maintaining a peaceful indoor environment.

The Daikin system offers various operational modes like Dry, Fan, Auto, and a Powerful Operation mode, providing flexibility for different climate conditions and personal preferences. The included installation kit and wall mounting bracket simplify the setup process, making it a more user-friendly option for those undertaking renovations or new constructions.

However, there are a few drawbacks to consider. The product is not Energy Star rated, which may be a concern for those particularly focused on energy savings. Additionally, the system is designed for single-zone use, which might not be suitable for users needing multi-zone control. Given its advanced features and high efficiency, this Daikin mini split is ideal for those looking for robust climate control in larger spaces, but its single-zone limitation and lack of Energy Star certification may not meet everyone's requirements.
