10 Best Mini Split Units 2025 in the United States

The YITAHOME 18000 BTU Mini Split is a solid choice if you need efficient cooling and heating for a space up to about 1250 square feet. It has a good cooling capacity suitable for medium-sized rooms like bedrooms, living rooms, or small commercial spaces. With a SEER rating of 19, it’s quite energy-efficient, which helps save on electricity costs over time, and its inverter compressor enhances performance and efficiency by adjusting power as needed. This model runs quietly at about 47 decibels, so it won’t be disruptive in your home. It’s also WiFi-enabled and works with Alexa, letting you control it conveniently from your phone or smart devices.

The system offers five different modes, including energy-saving and air purification features, which improve air quality and comfort. It is a single-zone unit, making it best suited for cooling or heating one main area rather than multiple rooms. Installation requires professional help and comes with a complete kit, but be aware that the components may arrive separately and setup isn’t DIY-friendly.

Maintenance is relatively easy thanks to a washable air filter and an auto-clean function, keeping upkeep simple. If you want a reliable, quiet, and smart mini split for a single room or open area, this unit meets those needs effectively. For those needing to cool multiple zones, exploring multi-zone systems might be a better option.

The Senville LETO Series Mini Split is a solid choice if you need a 2-ton (24,500 BTU) unit capable of cooling or heating spaces up to around 1,250 square feet. Its SEER rating of 17 is respectable, meaning it’s fairly energy-efficient for year-round use, complemented by an inverter compressor that adjusts power use to save energy. The heat pump function works efficiently down to about 5°F, so it can provide heat in moderately cold climates. Noise level is quite low at 34 dB, which should keep your environment quiet and comfortable. This model supports one zone, so it’s best suited for single-room or open-plan areas rather than multiple zones.

Installation includes all necessary components and refrigerant for up to 25 feet of piping, but professional installation is required and labor costs are extra. The unit integrates with Alexa for convenient voice control and remote app access, a nice modern feature that can enhance ease of use. One downside is that the product is rated below some energy star standards and is imported from China, which may concern buyers focused on certification or support. The 5-year warranty on the compressor and parts offers good peace of mind, though labor isn't covered.

This mini-split fits well for homeowners or small businesses looking for a powerful, quiet, and smart-controlled system primarily for a single zone.

The COSTWAY 18000BTU Mini Split is a solid choice for cooling and heating rooms up to about 1250 square feet, thanks to its good BTU capacity and a strong 1.5-ton heat pump. Its SEER rating of 19 means it’s quite energy efficient, which helps lower electricity bills. The unit uses modern R-32 refrigerant, which is better for the environment compared to older types. You get five operation modes including cooling, heating, dehumidifying, and fan options, plus handy features like ECO mode and a turbo boost for quick comfort.

Noise level is around 56 dB, which is moderate—quiet enough for most living spaces but possibly noticeable in very quiet rooms. The remote control and smart timer add convenience, and the self-cleaning function helps reduce maintenance effort. However, installation must be done by a licensed HVAC professional, which adds to initial setup cost and complexity.

This model is a single-zone system, so it’s best suited for one main area rather than multiple rooms. For those seeking a reliable, energy-saving mini split that covers a medium-sized space while maintaining reasonable noise levels, this unit fits well, provided you are comfortable with professional installation requirements.
