10 Best Mini Splits 2025 in the United States

The Senville LETO Series Mini Split is a solid choice if you're looking to cool or heat a space around 1,250 square feet. It delivers 24,500 BTU, which means it has strong cooling and heating power suitable for medium to larger rooms or multiple connected areas (zones). It comes with a good energy efficiency rating (SEER 17), helping reduce electricity bills compared to less efficient units. The noise level is quite low at 34 decibels, so it won't disturb your daily activities or sleep.

This model is versatile, offering cooling, heating down to 5°F (which covers most mild winters), a dehumidifier, fan, and a turbo mode for quick temperature changes. A standout feature is its Alexa compatibility, allowing you to control it through voice commands or a smartphone app for convenience. Installation requires a professional since it comes with a complete kit but no DIY setup instructions, and the unit includes a 16-foot copper line set pre-loaded with refrigerant.

The warranty covers parts and compressor for 5 years, providing peace of mind, though labor costs aren't included. One drawback is that it’s not rated under the BEE Star program, which might matter in some regions focused on strict energy standards. While it supports two tons of capacity, it’s designed generally for single-zone setups unless you install multiple units. This mini-split is a stylish and efficient option for homes or small businesses seeking quiet, reliable climate control with smart features.

The Senville LETO Series Mini Split Air Conditioner Heat Pump is a compact and efficient option for cooling and heating smaller spaces. With 9000 BTU, it’s suitable for rooms up to 400 square feet, making it a good fit for bedrooms, living areas, and even small commercial spaces. Its SEER of 21.5 indicates excellent energy efficiency, potentially lowering your energy bills. Additionally, the system includes a heat pump that works even in temperatures as low as 5°F, making it versatile for year-round use.

The noise level of 25 dB ensures quiet operation, which is ideal for maintaining a peaceful environment. The unit supports one zone, so it’s best suited for single-room applications rather than whole-house solutions. A notable special feature is its compatibility with Alexa, allowing for convenient voice control and integration into smart home systems. However, it's important to note that the system requires professional installation, which could add to the initial cost. The installation kit is comprehensive, including a 16ft line set and communication wire, but labor costs are not covered under the warranty.

With a 5-year warranty on parts and the compressor, Senville provides good long-term support. The device is not Energy Star compliant, which might be a consideration for those prioritizing energy standards. Lastly, the stylish design ensures it won’t be an eyesore in any setting.

Its inverter system and DC Inverter technology help save up to 30% on power, making it a cost-effective option in the long run. Additionally, the unit is compatible with Alexa and WiFi, allowing for convenient remote control operation. The inclusion of smart functions like 4D air flow, multiple fan speeds, and various modes (heating, cooling, dehumidifying) adds to its versatility and user comfort.

This mini-split system requires professional installation due to the need for line-set vacuuming and potential adjustments to freon levels if the line-set length is altered. It is not suitable for DIY installation, which might be a drawback for some users. With a noise level of only 35 dB, it operates quietly, making it ideal for use in bedrooms or living spaces without disturbance. The comprehensive installation kit provided simplifies the setup process for professionals.

The DELLA Versa Series is a reliable and efficient mini-split AC for larger spaces, combining advanced technology with user-friendly features, though it requires professional installation.
