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 Daikin 12,000 BTU Oterra Mini-Split is a strong choice for cooling and heating spaces up to about 550 square feet. It offers a solid 12,000 BTU cooling capacity and 13,500 BTU heating, covering a useful temperature range suitable for many climates, including cold winters down to 5°F and hot summers up to 118°F. One of its biggest strengths is its high energy efficiency with a 21 SEER2 rating, meaning it uses less electricity to keep your room comfortable, which can save money on utility bills over time. The system uses the eco-friendly R32 refrigerant and includes helpful features like automatic defrosting and a special filter that improves air quality.

Installation is typical for a ductless split system with wall-mounted indoor and outdoor units, which works well in rooms where traditional ductwork isn't possible. It also comes with smart controls and auto-changeover between heating and cooling for convenience. The installation kit is included but professional installation is recommended to ensure proper setup. While designed for a single zone, it may not be ideal for larger or multiple rooms without adding extra units.

This Daikin model is efficient, reliable, and packed with features suited for homeowners looking to efficiently heat and cool a medium-sized space without ducts.

The Senville 36000 BTU Quad Zone Mini Split is a solid choice for those needing climate control across multiple rooms, as it supports up to four zones with individual temperature adjustments. Its 36000 BTU (3 ton) cooling capacity suits medium to large spaces, roughly up to 1800 square feet, making it practical for homes or small commercial areas. With a SEER rating of 22.5, this system is quite energy efficient, which helps reduce electricity bills. It also works well in colder climates thanks to its Arctic Heat Pump technology, functioning effectively even when temperatures drop to -22°F. Noise is impressively low at just 23.5 decibels, so it operates quietly without disturbing your living or working space.

The unit’s Alexa compatibility adds convenience by allowing voice controls and remote adjustments via an app, which can also help save energy by setting schedules. Installation requires professional help since it’s a split system with separate indoor and outdoor units, and it’s not a simple DIY project. Weighing 225 pounds and including a 16-foot installation kit, this package provides everything necessary for setup, but keep in mind the outdoor unit’s size and the need for proper placement.

This mini split is well suited for users seeking efficient, quiet, multi-zone temperature control with smart features, especially in homes or small businesses that can accommodate professional installation.
