10 Best Mini Split Units 2025 in the United States

The MRCOOL Easy Pro 24,000 BTU mini-split unit is a solid choice for heating and cooling a space up to about 1,050 square feet. Its 24,000 BTU capacity should provide reliable comfort for medium-sized rooms or small homes. One of its biggest advantages is the easy DIY installation, which can save you money on professional setup and reduce hassle. This unit also operates quietly at 43 decibels, making it suitable for bedrooms or living areas where low noise is important. It offers both heating and cooling year-round, controlled conveniently through WiFi and compatible with voice assistants like Google and Alexa, which adds a modern touch and ease of use.

The product has a 2-star BEE rating, indicating it may consume more power compared to other mini-splits with higher energy efficiency ratings. It supports only a single zone, so it is best suited for one main area rather than multiple rooms. Maintenance and running costs should be reasonable due to the inverter technology.

This MRCOOL model is ideal if you want a quiet, easy-to-install, and smart-controlled mini-split for a single zone, although it may not be the most energy-efficient option available.

The Senville AURA Series Mini Split is a solid choice if you need a quiet and energy-efficient cooling and heating solution for a medium-sized room (up to about 750 sq ft). With a 12,000 BTU capacity and a very high SEER rating of 25.5, it’s designed to keep your space comfortable while saving on electricity. The unit is Energy Star certified and performs well even in extreme cold, thanks to its inverter heat pump technology. It’s also Alexa-enabled, allowing easy voice or app control, which is convenient if you want to adjust settings remotely. Noise levels are impressively low at 24 dB, making it unobtrusive in bedrooms or living areas.

This model is a single-zone system, so it’s best suited for cooling and heating one room rather than multiple zones or large homes. Installation is not DIY-friendly and requires a professional, which adds to the initial cost and effort. While the product comes with a strong warranty (10 years on the compressor), the included line set is 16 feet long, so placement options may be somewhat limited.

If you’re looking for an efficient, quiet mini-split for one room and don’t mind arranging professional installation, this unit offers good value with modern smart features and reliable performance.

The MRCOOL 12000 BTU Easy Pro Series mini split is a good option for anyone needing both heating and cooling in spaces up to about 550 square feet, such as a small room, office, or commercial spot. With 12,000 BTUs, it provides solid power for this size range, making it well-suited for year-round use. The unit runs quietly at 43 dB, which means it won't be very disruptive in most environments.

This model uses a modern refrigerant (R-454B) that’s better for the environment compared to older types. The DIY design and features like refrigerant leakage detection and easy-to-clean filters make installation and maintenance simpler for users comfortable with basic home projects. However, the BEE Star Rating of 2 indicates moderate energy efficiency, so it might not be the most cost-effective choice over time if energy savings are a top priority. Also, it supports a single zone, so it’s best for cooling or heating one room or area rather than multiple rooms.

If you want a straightforward, reliable mini split with heating and cooling that’s easy to install yourself, the MRCOOL Easy Pro series fits well. Keep in mind that its energy efficiency is average, and it’s designed for smaller spaces rather than whole-house multi-zone setups.
