10 Best Ductless Mini Split Systems 2025 in the United States

The Senville LETO Series Mini Split is a solid choice for anyone looking to cool or heat a medium-sized space, up to about 1250 square feet. It offers 24,000 BTUs of cooling power, which is enough for larger rooms or small apartments. The SEER rating of 17 means it’s fairly energy-efficient, helping to keep electricity bills reasonable. It also includes a heat pump that works down to 5°F, so it can provide warmth in cooler weather without needing a separate heater. A notable plus is that it works with Alexa, letting you control temperature easily by voice or app, which adds convenience.

At just 34 decibels, the noise level is quite low, making it a good option for bedrooms or offices where quiet is important. The package comes with everything needed for installation, including a 16-foot line set and remote control, but professional installation is required, which is typical for mini splits. The warranty covers parts and the compressor for 5 years, offering some peace of mind, though labor costs aren’t included.

One downside is that it’s a single-zone system, so it’s best suited for one main area rather than multiple rooms. Also, while the energy efficiency is good, it isn’t top-tier compared to some newer models. The product is made in China, which isn’t an issue for performance but might matter to some buyers. Lastly, its stylish, compact design fits well in varied settings, from homes to small businesses. This model is a dependable mini split for those who want a reliable, quiet, and smart-controlled unit with heating and cooling in one. It’s ideal if you need a straightforward system for a single zone and value ease of use and decent energy savings.

The Senville LETO Series Mini Split is a solid choice for anyone looking to cool or heat single-zone spaces like bedrooms or small living areas. Its 12,000 BTU capacity and 1-ton rating make it suitable for medium-sized rooms. The system stands out with a high SEER rating of 19, meaning it operates efficiently and can help reduce electricity bills compared to older models. It also offers an HSPF rating through its heat pump function, which works down to 5°F, so it can provide heating in mild winter conditions. One of its strongest points is the smart Alexa compatibility, allowing easy temperature control via voice or app, which adds convenience. The included installation kit with pre-charged refrigerant makes preparation easier, but professional installation is still necessary, which can add to initial costs and complexity.

Noise levels are generally low due to the inverter technology, making it suitable for quiet environments like bedrooms or offices. However, it lacks Energy Star certification, which some buyers might consider when prioritizing energy savings. The package comes with a 5-year warranty on parts and compressor, offering good peace of mind. While the unit is well-designed and stylish, it is intended for single-zone use only, so it might not fit multi-room needs without purchasing additional units. This mini split is a reliable, energy-efficient system with smart features ideal for users seeking comfort and convenience in a compact system.

The DELLA Vario 24000 BTU Mini Split is a solid choice for cooling or heating a medium to large space—up to about 1500 square feet. Its 24000 BTU capacity and 19 SEER2 rating make it quite energy efficient, helping save on electricity bills compared to less efficient units. It also includes a 2-ton heat pump that operates well even in cold temperatures down to -4°F, making it versatile for year-round use. Noise is kept low at roughly 35 dB, so it runs quietly without disturbing your daily activities.

One standout feature is the smart sensor in the remote control that adjusts airflow and temperature based on room conditions, adding to comfort and efficiency. It also supports Alexa and WiFi control, which is convenient if you like smart home integration. However, this system covers only a single zone, so if you want to cool or heat multiple rooms independently, you might need to look for multi-zone models.

Installation isn’t DIY-friendly—it requires a professional to vacuum the line-set and handle refrigerant adjustments, so be prepared for extra installation costs. Maintenance is typical for ductless systems and should be performed regularly to keep it running smoothly. This unit is well-suited for homeowners looking for an energy-efficient, quiet, and smart-controlled mini split for a single zone with solid heating and cooling capabilities.
