10 Best Ductless Air Conditioners 2025 in the United States

The Senville LETO Series Mini Split is a 24,000 BTU (2-ton) air conditioner and heat pump designed to cool or heat spaces up to about 1250 square feet. It has a strong SEER rating of 17, meaning it uses energy efficiently, which can help keep electricity bills lower compared to less efficient units. One of its notable strengths is the very quiet operation at just 34 dB, making it suitable for bedrooms or living rooms where low noise is important. This model supports Alexa voice control, allowing you to adjust settings easily from a phone or smart speaker, adding convenience.

It’s a versatile 4-in-1 system offering cooling, heating (effective even in colder weather down to 5°F), dehumidifying, and fan options, making it useful year-round. The product includes everything needed for installation except labor, but professional installation is required, which adds to upfront costs and complexity. The unit comes with a 5-year warranty on parts and compressor, which is reassuring. However, it only supports a single zone, so it’s best for cooling or heating one main area rather than multiple rooms. It is factory charged for refrigerant up to 25 feet of line set, good for typical setups but may require extra refrigerant for longer distances.

The design is sleek and modern, fitting well in homes or small businesses. On the downside, it’s imported from China, and while it’s AHRI certified and ETL listed, it doesn’t have a BEE star rating for energy efficiency compliance in some regions. This model is well suited for those who want a quiet, energy-efficient, versatile mini-split with smart features for a single room or open area, though buyers should be prepared for professional installation costs and limited multi-zone capability.

The Senville LETO Series Mini Split Air Conditioner Heat Pump is a versatile and powerful option for those seeking both cooling and heating solutions. With a cooling capacity of 18,000 BTU, it can efficiently manage temperature control in spaces up to 1,000 square feet, making it suitable for larger rooms or small commercial spaces. The SEER rating of 19 indicates good energy efficiency, although it is not Energy Star compliant, meaning it might not be the most efficient option available.

One of its notable features is the low noise level of 30 dB, which ensures quiet operation, beneficial for environments like bedrooms and offices where minimal noise is crucial. This unit is designed to cover a single zone, which limits its use in multi-room setups but is ideal for concentrated heating or cooling in a specific area. Installation is somewhat straightforward with the included kit, though professional installation is required, which could add to the initial cost.

Maintenance is made easier with pre-loaded refrigerant and a 5-year warranty on parts and the compressor, although labor is not included in the warranty. Additional features such as integration with Alexa for voice control, a dehumidifier, fan, and turbo function add to its versatility, making it a comprehensive all-season appliance. The product is also aesthetically pleasing, suitable for both home and business environments.

The Senville 36000 BTU Tri Zone Mini Split Air Conditioner Heat Pump is designed for cooling and heating up to three separate rooms, making it a good choice for homes or small businesses that need individual temperature control in multiple spaces. With a powerful 3-ton capacity and an efficient SEER rating of 22.5, it promises strong performance and energy savings. The inclusion of Alexa support allows for convenient voice control and remote temperature adjustments, helping reduce energy costs when you're away.

This system is AHRI certified and uses the environmentally friendlier R-454B refrigerant. Its Arctic Heat Pump technology ensures reliable heating even in very cold climates, suitable for regions with harsh winters. The package comes with everything needed for installation except labor, but it requires professional installation to maintain the warranty, which covers parts for 5 years and the compressor for 10 years. This means upfront installation costs and no DIY option, which might be a drawback for some.

Mini splits like this typically run quietly, which should make it comfortable for bedrooms or offices. The sleek white design fits well in most interiors. It is suitable for users looking for efficient, customizable climate control across several rooms with smart features, provided they are ready to invest in professional installation and maintenance.
