10 Best Mini Split For Garage 2025 in the United States

The Senville LETO Series Mini Split is a solid choice for cooling and heating a garage space of up to about 1,250 square feet, thanks to its powerful 24,500 BTU (2-ton) capacity. Its SEER rating of 17 means it uses electricity efficiently, helping keep energy costs reasonable, which is important for year-round garage use. It also functions as a heat pump working in temperatures as low as 5°F, making it useful during cold winters. Noise is kept low at just 34 dB, so it won’t be disruptive if you’re working in or near your garage.

The system is Alexa-enabled, allowing convenient control through voice commands or an app—handy if you want to adjust settings without physically interacting with the unit. The 4-in-1 design covers air conditioning, heating, dehumidifying, and fan modes, which adds flexibility to maintain comfort and air quality.

Installation requires professional help and comes with a fairly complete kit including a 16-foot line set and remote, but labor costs are not included in the warranty. The warranty offers 5 years for parts and compressor, which is reassuring, though labor costs are excluded. While the unit is made in China, it is well-suited for garage owners wanting efficient, quiet climate control with smart features, provided they’re comfortable with professional installation and managing warranty coverage.

The TOSOT 30,000 BTU mini-split is a powerful option for cooling and heating spaces up to around 1800 square feet, making it a solid choice for larger garages. Its 22 SEER2 rating means it’s designed to use energy efficiently, which can help lower electricity bills compared to less efficient units. It also offers reliable heating down to -13°F, so it can handle cold climates well. Noise levels are impressively low, operating between 22 to 36 decibels, which is quieter than many other systems and helpful if you want a peaceful garage or workshop.

Installation includes both indoor and outdoor units along with a 16-foot copper line set, which is fairly standard but might require professional help to set up properly. The system supports smart features like WiFi control through an app and voice commands, adding convenience if you prefer managing your garage climate remotely. The sturdy packaging and a 5-year warranty provide some peace of mind about durability and support.

The unit is fairly large and heavy, so it needs sufficient space and solid mounting surfaces for installation. Also, the product’s shipping in multiple packages could complicate setup if all parts don’t arrive together. While it’s marketed for residential use, its size, power, and quiet operation make it particularly well-suited for garage environments where both heating and cooling are needed without disturbing noise.

The TOSOT Aoraki Series mini-split is a strong choice if you need reliable heating and cooling for a garage up to around 1500 square feet. Its 24,000 BTU capacity provides solid power to handle both warm and chilly conditions, and the 24 SEER2 rating means it’s quite energy-efficient, which can help lower electricity bills compared to less efficient models. This unit stands out with its ability to heat in very cold climates thanks to a dual electric heating belt and can even cool effectively in near-freezing outdoor temperatures, useful if your garage experiences extreme weather.

Noise is kept very low indoors, at just 30 decibels, so it won’t disturb your work or sleep if your garage is connected to living spaces. It also offers WiFi control, letting you adjust settings remotely for convenience. One unique feature is support for an optional energy recovery ventilator (ERV) system, which can improve air quality and balance humidity by recycling energy from exhaust air, though installing this requires additional vents and professional help. The black finish is sleek, but the unit is relatively large and heavy, meaning installation is best handled by a pro.

This product is well-suited for those seeking a durable, energy-saving mini-split with good cold climate heating and smart features for their garage. However, the need for separate components like the ERV and the complexity of installation may not appeal to users looking for a simple plug-and-play solution. Some may also find the price higher than basic mini-splits that lack these advanced features.
