10 Best Ductless Mini Split Systems 2026 in the United States

The Senville AURA Series Mini Split Air Conditioner Inverter Heat Pump is an efficient choice for those needing powerful climate control, offering 33000 BTU of cooling power suitable for larger spaces. With a SEER rating of 19.5, it ensures energy efficiency which is ideal for reducing electricity bills, and its Energy Star certification further confirms this efficiency. Heating capabilities are also robust, functioning effectively in extremely cold conditions down to -22°F, making it suitable for regions with harsh winters.

The system’s noise level is relatively low at 35 dB, promising quieter operation which is great for both residential and commercial settings. It supports voice control through Alexa, adding convenience for tech-savvy users who enjoy smart home integration. However, it does require professional installation, which may incur additional costs and effort. Maintenance might be straightforward given the 5-year parts and 10-year compressor warranty, although labor is not covered under warranty, potentially leading to extra expenses for part replacements.

The design is versatile and aesthetically pleasing, fitting well into various environments. On the downside, the system is not DIY-friendly and the substantial weight and size may pose handling challenges during installation. Ideal users are those needing high-capacity cooling and heating with smart home compatibility and are prepared for professional setup.

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.

The Daikin 24,000 BTU Entra R32 Series ductless mini split system is a solid choice for cooling and heating spaces up to 1,500 square feet, making it suitable for medium-sized rooms or open areas such as sunrooms, basements, or garages where traditional ductwork is difficult. It delivers a strong cooling capacity of about 22,400 BTUs and heating up to 23,000 BTUs, with a flexible range that adapts well to different climates, working efficiently in temperatures from 50°F to 115°F for cooling and down to 5°F for heating.

With an 18 SEER2 rating and 9 HSPF, this model is energy efficient, helping reduce electricity bills while maintaining year-round comfort. The system uses environmentally friendly R-32 refrigerant and DC inverter technology, which further enhances efficiency and temperature control. Noise is kept low at 38 decibels, so it won’t disturb daily activities or sleep.

Installation is simplified by the included 15-foot Maxwell installation kit and wall mounting bracket, which is helpful especially if you’re doing a retrofit or adding AC where ductwork isn’t feasible. However, this model supports only a single zone, meaning it cools or heats one area rather than multiple rooms independently. Additional features like ECO+ mode for energy savings, air purification filters, and smart self-diagnostics make it user-friendly and contribute to better indoor air quality. Some users might find basic maintenance manageable, but professional installation is recommended to ensure optimal performance. This Daikin mini split system suits homeowners seeking an efficient, quiet, and environmentally friendlier heating and cooling option for a single-zone space, especially where duct installation is not practical. For multi-zone capabilities, other models should be considered.
