10 Best Mini Splits 2025 in the United States

The MRCOOL 18000 BTU 5th Gen DIY Mini Split is a solid choice for cooling and heating spaces up to about 800 square feet, making it suitable for a single room or small office. It offers a strong BTU rating of 18,000 along with heating capability, so it works well year-round. The SEER rating of 22.5 means it is quite energy efficient compared to many other models, which can help save on electricity bills. Noise level is reasonably low at 46 dB, so it won’t be too disruptive indoors.

One standout feature is the DIY installation: it comes with pre-charged line sets and requires no special tools or professional training, which many users will find convenient and cost-saving. The unit is also smart home compatible with Google Assistant and Alexa, allowing for easy temperature control from your phone or voice commands.

It is important to note that this model only supports a single zone, so it's not ideal if you want to condition multiple rooms independently. Also, the BEE Star Rating is just 1 star, which suggests it might not meet higher energy efficiency standards in some regions. Additionally, it operates on a 230V power supply, so you’ll want to ensure your home’s electrical setup matches. If you need an efficient, quiet, and easy-to-install mini split for one area and appreciate smart features, this MRCOOL unit is worth considering.

The Senville LETO Series Mini Split is a solid choice if you’re looking for a quiet and efficient 1.5-ton air conditioner and heat pump system suitable for about 1,000 square feet. With an 18,000 BTU cooling capacity and a good SEER rating of 19, it offers energy-efficient performance that can help keep electricity costs reasonable. This model is versatile, working as both a cooling and heating unit, and can function in cold weather down to about 5°F, making it useful year-round in many climates. It also includes handy features like Alexa compatibility, so you can adjust settings with your voice or remotely via an app, which adds convenience. Noise levels are quite low at 30 dB, meaning it won’t disturb your living or working space.

It is designed for single-zone use only, so it’s best suited for one room or open area rather than multiple rooms. Installation requires a professional, and although the package comes with necessary parts including a 16-foot refrigerant line, installations beyond that length might incur extra costs. The system is not Energy Star certified, which might be a consideration if you prioritize top energy-saving certifications. The included warranty covers the compressor and parts for five years, which offers some peace of mind.

This mini-split is a strong option for homeowners or small businesses wanting a quiet, efficient, and smart-controlled heating and cooling system for a single space, but it may not be the best fit if you need multi-zone capabilities or the highest energy standards.

The Senville AURA Series Mini Split Air Conditioner Inverter Heat Pump is a powerful and efficient option for both residential and commercial spaces. With a substantial 24000 BTU cooling power, it can comfortably handle areas up to 1250 square feet. The impressive SEER rating of 20.5 signifies its high energy efficiency, which can lead to significant savings on energy bills. Additionally, it boasts a quiet operation with a noise level of just 36 dB, making it ideal for bedrooms or living rooms where noise might be a concern.

One of the standout features is its compatibility with Alexa, allowing for easy voice control and integration into smart home setups. The unit comes with everything necessary for installation, including an indoor air handler, outdoor condenser, and a 16ft. installation kit. However, it's important to note that professional installation is required, which might add to the initial cost.

The product is also backed by a solid warranty: 3 years for parts and 7 years for the compressor. While the warranty is comprehensive, it does not cover labor costs, which could be a drawback for some users. In summary, the Senville AURA Series offers a blend of performance, efficiency, and smart features, making it a great choice for those looking to cool or heat larger spaces effectively. However, potential buyers should be aware of the additional costs associated with professional installation and labor not covered under warranty.
