10 Best Mini Splits 2025 in the United States

The COSTWAY 12000 BTU mini split is a solid choice if you need a compact, energy-efficient unit to cool or heat a medium-sized room (up to about 750 square feet). Its 1-ton heat pump and 20 SEER rating mean it uses less electricity compared to many older models, helping keep energy bills lower. It offers five modes—including heating, cooling, dry, and fan—to suit different weather conditions year-round. The inverter technology helps maintain a steady temperature without constantly switching the compressor on and off, which saves power and extends the unit’s life. Noise is fairly low at around 51 decibels, so it won’t disturb a quiet room, and features like a remote control with a sleep timer add convenience.

The self-cleaning function and washable filter help maintain good air quality, while the auto-defrost feature protects the outdoor unit in cold weather. Installation requires a licensed professional and involves mounting the indoor and outdoor units separately. Some potential drawbacks are that it only supports a single zone, so it’s best for one main living area rather than multiple rooms. Also, the 115V power requirement may limit placement options depending on your home’s wiring.

With smart-like features such as iFEEL, which senses temperature around the remote, the unit still lacks full smart home integration. This mini split is well-suited for users who want dependable heating and cooling with a focus on energy savings and quiet operation in a single room setup.

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 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.
