10 Best Mini Splits Ac 2025 in the United States

The Senville LETO Series Mini Split is a solid choice if you're looking to cool or heat spaces around 1,250 square feet. With a 24,000 BTU (2-ton) capacity, it’s powerful enough for medium-sized rooms like living areas or small commercial spaces. Its SEER rating of 17 means it offers good energy efficiency, helping you save on electricity bills compared to older models. Noise-wise, it’s fairly quiet at 34 decibels, so it won't disturb your daily activities or sleep. This model supports a single zone, meaning it’s best suited for one main space rather than multiple rooms.

One of the standout features is its compatibility with Alexa and app control, allowing you to adjust settings with voice commands or remotely, which adds convenience. The 4-in-1 function supports air conditioning, heating (down to 5°F or -15°C), dehumidifying, and fan modes, making it a versatile all-season unit. Installation includes necessary parts and a 16-foot line set, but professional installation is required, which can add to upfront costs. Plus, while it comes with a 5-year warranty on parts and the compressor, labor for repairs isn’t covered.

It is manufactured in China, which may concern those preferring locally made products. Additionally, it doesn’t support multiple zones, so if you want individual temperature control in several rooms, this unit won’t fit that need. The Senville LETO is a stylish, efficient, and smart mini-split that is great for users who want an easy-to-control, single-zone system to keep their space comfortable year-round.

The MRCOOL 12000 BTU Easy Pro Series mini split is a solid choice for cooling and heating spaces up to about 550 square feet. Its 12,000 BTU capacity is suitable for small to medium rooms, making it a versatile option for homes, offices, or small commercial areas. The unit runs quietly at 43 dB, which is about the noise of a quiet conversation, so it won’t be disruptive in most settings. It offers both heating and cooling, allowing you to use it year-round, which is a nice bonus compared to AC-only models.

Installation is designed to be DIY-friendly, which can save you money on professional setup, but some users might still prefer professional help to ensure optimal performance and proper refrigerant handling. The system includes smart features like a timer and refrigerant leak detection, adding convenience and safety. The Active Clean Technology helps maintain good indoor air quality by reducing odors and making the filters easier to clean.

The unit supports a single zone, so if you need to cool multiple rooms separately, you'd have to invest in additional units. This mini split provides a practical balance of heating and cooling with user-friendly features, making it well suited for those needing a straightforward, quiet, and flexible solution for a single room or space.

The MRCOOL DIY 36K BTU mini-split is a solid choice for cooling a single large zone up to around 1500 square feet. Its 36,000 BTU (3 tons) capacity makes it powerful enough for bigger spaces, while the high 18 SEER rating means it operates efficiently to help save on energy bills. At just 34 dB, the indoor unit runs quietly, which is great for keeping noise distractions low.

Installation is a standout feature because it’s designed for DIY with pre-charged quick connect lines, so you don’t need special tools or professional help, saving time and installation costs. The unit also offers smart controls via your phone, letting you adjust settings remotely for added convenience. Plus, it has useful features like leakage detection to protect the compressor and an auto-restart function after power outages.

This model only supports one zone, so it’s not suitable if you need to cool multiple rooms separately. While the product is Energy Star certified for efficiency, the BEE star rating is only 1, which may be less meaningful depending on your location. The weight is quite heavy (262 pounds), so some assistance may be needed during installation. This MRCOOL mini-split is a great pick for someone looking for an efficient, quiet, and easy-to-install AC system for a single large room or open area.
