10 Best Mini Splits 2026 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 Della Hyper Heat mini split is a strong choice if you're looking to cool or heat a space of about 1,000 square feet. With an 18,000 BTU capacity and a 1.5-ton heat pump, it can handle medium-sized rooms comfortably. It stands out with a high energy efficiency rating (23 SEER2), which means it can save you money on electricity bills compared to less efficient models. It also works as a heater in very cold weather, effective down to -13℉, making it suitable for colder climates. Noise levels are quite low at 31 decibels, so it won’t disrupt sleep or work.

The unit supports smart features like WiFi control and Amazon Alexa compatibility, allowing easy temperature adjustments from your phone or voice commands. Installation requires professional help due to the technical setup and refrigerant handling, so it’s not a do-it-yourself option and may add to upfront costs. The product comes with a comprehensive installation kit, but remember that any modification of the line set affects refrigerant balance and demands expert attention.

The design is sleek and quiet, fitting well into homes or small commercial spaces. It supports only a single zone, so it’s best for one main area rather than multiple separate rooms. If you want a reliable, energy-saving mini split with modern smart controls and serious heating power for cold winters, this unit performs well — just plan for professional installation and one-zone use.

It boasts an impressive 19 SEER2 rating, indicating high energy efficiency, and features a 2-ton heat pump that works efficiently even in cold environments down to 5°F. 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.
